38 27 Inpatient Release 27: 2019 Q1 – 2020 Q2 Mayo Regional Hospital (200066) Resubmissions: Hospital Specific Notes

As communicated in past releases, due to a change in the Mayo Regional Hospital’s EHS system, starting with 2019 Q1 data through Q2 2020 the hospital incorrectly submitted ED services in the inpatient data that should have been included in the outpatient data; as a result, the volume of ED visits has been comparatively high in the inpatient data. This situation was addressed by the facility through a resubmission of inpatient and outpatient records for January 2019 through June 2020. MHDO has replaced the affected encounter records with the resubmitted records and has confirmed that the volume of ED records has returned to comparable levels for the affected period through the most current release period (2020 Q3). These data will be available as a separate patch file or the MHDO can release full replacement files if needed. Users should contact the MHDO to obtain these data.

31 25 Hospital Specific Notes (2020 Q1-Q2 Inpatient Release 25):

Total Volume Quality Check: We compared the encounter volume for each quarter against the previous quarter and flagged changes equal to or greater than 20%. The following facilities have a 20% to 30% volume decrease in 2020 Q2 compared to 2020 Q1: Calais Regional Hospital (200055), Central Maine Medical Center (200024), LincolnHealth (201302), Millinocket Regional Hospital (200003), Mount Desert Island Hospital (200038), Northern Light Acadia Hospital (200004), Northern Light AR Gould Hospital (200018), Northern Light Blue Hill Hospital (200051), Pen Bay Medical Center (200063), Penobscot Valley Hospital (200062), Rumford Hospital (200016), and York Hospital (200020). Northern Light Inland Hospital (200041) has a 25% decrease in 2020 Q1 from 2019 Q4. All of these facilities have confirmed the accuracy of the volume changes, and most have indicated that the reduction in services is in response to the COVID-19 pandemic. Others verified the submitted volume as correct but did not provide a specific reason for the change.

Encounter volume decreases larger than 30% in 2020 Q2 compared to 2020 Q1 have been noted below and hospital explanations provided.

Riverview Psychiatric Center (200056) with a 62% volume decrease - “Due to COVID 19, the hospital has restricted the number of admissions and discharges. This will be an ongoing process until we are able to fully function.”, Northern Light C.A. Dean Hospital (200023) with a 59% volume decrease - “Volume reported is accurate”, and St. Joseph Hospital (200001) with a 39% decrease - “Drop in volume has been validated and is a direct result of COVID.”

Total ED Volume Quality Check: We compared 2020 Q1 and Q2 ED% against the overall 2019 Q1-Q4 ED% to see if the absolute percentage point difference is 10 or higher. Notes for flagged facilities are below.

Bridgton Hospital (200007): ED visits decreased in 2020 Q2. To date the hospital has not provided any insight.

Mayo Regional Hospital (200066): As previously communicated, due to a change in the Mayo Regional Hospital’s EHS system, the facility submitted ED services in the inpatient data starting with 2019 Q1 data that historically had been included in the outpatient data; as a result the volume of ED visits has been comparatively high. This situation continues to be applicable in the 2020 Q1-Q2 release. The facility has indicated that the inpatient encounters affected by this situation are those with Primary Payer Category values of 01 MEDICARE, 02 MEDICAID (MaineCare), 04 TRICARE/USVA, 09 WORKERS COMPENSATION and 12 MEDICARE ADVANTAGE AND Revenue code values of 0450.

Mayo Regional Hospital has committed to resolving this issue beginning with their Q3 2020 submissions to MHDO. They have also committed to resubmitting CY 2019 and 2020 Q1-Q2 records with the appropriate ED services in the outpatient file to MHDO by January 15, 2021. The updated data will be available for data users in March 2021. The MHDO will work with current data users to determine who would like to receive the updated release files.

Lastly, MHDO investigated ways to remove the ED services portions for the 2020 Q1-Q2 data; however, we have determined that it is not possible to do solely based on the information submitted on the encounter. We apologize for any confusion.

29 24 Hospital Specific Notes (Q4 2019 Inpatient Release 24):

Total Volume Quality Check: We compared volume for Q4 against the previous quarter Q3 and flagged potential issues if the changes are equal to or greater than 20%. Notes for three flagged facilities are below.

Dorothea Dix Psychiatric Center (200057): The facility had an increase in the overall encounter volume from Q3 to Q4. The facility indicated that the increase is due to normal fluctuation in services month to month.

Mount Desert Island Hospital (200038): The facility had a decrease in the overall encounter volume from Q3 to Q4. The facility indicated that, as a Critical Access Hospital with 25 beds, their inpatient volume is volatile and is very dependent on providers available to care for patients.

Northern Light Blue Hill Hospital (200051): The facility had a decrease in the overall encounter volume from Q3 to Q4. The facility confirmed the accuracy of the volume change.

Total ED Volume Quality Check: We compared 2019 Q4 ED% against the overall 2018 Q1-Q4 ED% and flagged potential issues if the absolute percentage point difference is 10 or higher. Notes for two flagged facilities are below.

Bridgton Hospital (200007): Quality checks indicate ED visits decreased. To date the hospital has not provided any insight.

Mayo Regional Hospital (200066): As previously reported, MHDO’s data quality checks indicate ED visits continue to be high. According to the hospital there are ED encounters in the inpatient data that should be in the outpatient data, but unfortunately the new EHS system is not able to process correctly. The hospital is exploring possible solutions to this issue. In the interim, there are outpatient ED encounters that are included in the inpatient data. The outpatient ED records are identified as records with Primary Payer Category values of 01 MEDICARE, 02 MEDICAID (MaineCare), 04 TRICARE/USVA, 09 WORKERS COMPENSATION and 12 MEDICARE ADVANTAGE AND Revenue code values of 0450.

24 23 Facilities Status Updates

MHDO completed a review of the Support Facilities table that accompanies the Inpatient and Outpatient releases. Data for a subset of the facilities listed are no longer submitted under their original MHDO ID’s (SubmitterEIN in the encounter data and ifFacilityID in the Support Facilities table). To indicate this, the following changes have been made in the Support Facilities file:

(1) ‘Deactivated’ and ‘Closed’ statuses are added to the ifStatus field. ‘Deactivated’ indicates that the MHDO ID (SubmitterEIN in the encounter data or ifFacility ID) is no longer being utilized. ‘Closed’ indicates that the facility is no longer in operation.
(2) A Notes field is added to provide information about the facility history and any relevant impact to the data submission, as well as dates and details pertaining to the submitter’s status.

Additionally, the previous version of the Support Facilities table indicated that MHDO ID 200009 (Maine Medical Center) is the affiliated Hospital ID for submitters: 200103, 200104, 200147, 200148, 200149. The correct MHDO ID, 200032 (Stephens Memorial Hospital), is now displayed in the ifAffiliatedHospitalID field.

25 23 Hospital Specific Notes (Q3 2019 Inpatient Release 23):

Mount Desert Island Hospital (200038): The facility has a 22% increase in the overall encounter volume from Q2 to Q3. The facility indicated that the increase is due to a local nursing home that closed. Two new doctors joined the hospital’s staff.

Northern Light C.A. Dean Hospital (200023): The facility has a 29% decrease in the overall encounter volume from Q2 to Q3. The facility confirmed the accuracy of the volume change.

Calais Regional Hospital (200055): Quality checks indicate ED visits increased. The facility confirmed the accuracy of the change.

Mayo Regional Hospital (200066): The impact from Mayo’s transition to a new EHS system continues to give the appearance of a large increase in inpatient ED visits. According to the hospital there are ED encounters in the inpatient data that should be in the outpatient data, but unfortunately the new EHS system is not able to process correctly. The hospital is exploring possible solutions to this issue. In the interim, these outpatient ED encounters are included in the inpatient data. MHDO is working with Mayo Regional Hospital to determine if there is a way to identify these encounters in the inpatient data. If there is a way to do so, MHDO will send a follow up communication to the MHDO data users.

Northern Light Sebasticook Valley Hospital (200028): Quality checks indicate an increase in ED visits . The facility stated this is due to a higher overall census: “the facility is actively working on acute to acute transfers from other area hospitals as well as from the Northern Light Eastern Maine Medical Center’s Emergency Department.”
7/1/2019 9/30/2019
26 16 In the Q3 2018 Inpatient release, one encounter record (IPMB01_IDN = 49594007) had erroneously blank values in a subset of fields. The fields that were erroneously left blank for this IDN and the correct values they should have are the following: IPMVA30_MRNEncrypted (000072945), IPMVA20_LOS (1), IPMVA21_AGE (80), IPMVA23_RVHITS (16), and IPMVA25_EDFlag (1). 7/1/2018 9/30/2018

22 22 Hospital Specific Notes (Q2 2019):

Penobscot Valley Hospital (200062): The volume for this quarter has decreased since Q1; however, it is the same as Q4 2018’s. As reported 1/29/19 by Penobscot Valley Hospital, “The ripple effects of regional economic conditions including the loss of Lincoln’s major employer, Lincoln Paper and Tissue, have led to high unemployment rates, loss of commercial health insurance coverage, and families moving out of the area. In-patient admissions have decreased 65% and overall patient volume has decreased by nearly 10% over the last four years”.

Mayo Regional Hospital (200066): The percentage of ED visits appears to have increased when compared to the historical volume, however it is because ED charges for patients paying via Medicare have not been split out and moved to the outpatient data record. This record split must be done manually now, since the recent transition to a new EHS system; the facility notified MHDO that there is a delay in this process, which resulted in an apparent increase in the ED visit volume.

20 21 Hospital Specific Notes (Q1 2019):

Rumford Hospital (200016): The volume has increased from the previous quarter; however, the 2018 Q4 volume was unusually low. The Q1 2019 volume is in a normal range for this facility.

Mayo Regional Hospital (200066): The percentage of ED visits appears to have increased when compared to the historical volume, however it is because ED charges for patients paying via Medicare have not been split out and moved to the outpatient data record. This record split must be done manually now, since the recent transition to a new EHS system; the facility notified MHDO that there is a delay in this process, which resulted in an apparent increase in the ED visit volume.

Maine Medical Center (200009), MaineGeneral Medical Center Augusta (200015), Southern Maine Health Care (200019): In Q1 2019, these facilities had decreases in the self-pay volume when compared to the historical volume. MHDO has been notified by these facilities that the decrease is attributed to the MaineCare Expansion, effective since January 2019.

16 16, 19 Hospital Specific Notes (Q3 & Q4 2018):

Calais Regional Hospital (200055): Inpatient care capacity decreased from 25 to 10 hospital beds starting with June 2018.

Maine Coast Memorial Hospital (200050): Increase in volume from previous two quarters are normal volume. Q1 and Q2 were lower due to an issue with the vendor software, which was resolved for Q3 data.

Penobscot Valley Hospital (200062): Decrease in volume is due to hospital's new process to place patients in two-day observation rather than admitting with the inpatient status. Additionally, loss of a major employer in the hospital area has had an economic impact on this facility over the past years.

17 20 New Payer Category Codes – Patch File for Inpatient data prior to Q3 2018.

This release affects previously released Hospital Inpatient Encounter records for data prior to Q3 2018. It contains encounter rows that have had at least one of the following fields updated: IPMPY20_PAY1, IPMPY21_PAY2, IPMPY22_PAY3. The MHDO periodically reassesses payer names that were assigned Payer Category Codes of ‘99’ or null in previous releases to determine whether newly received data have brought the number of encounters associated with these names above the “10 or more encounters” threshold. Previously unassigned payer names found to be above this threshold are assigned a Payer Category Code and encounters that previously were coded with a null or ‘99’ are then updated with the new code. Enclave users and new data applicants who request data extracts in this date range will have access to the updated values. A patch file with these new Payer Category Codes is available by request for current data requestors who previously received data extracts in this date range.

4/1/2018 6/30/2018
11 15 Two duplicate records were noticed in already released inpatient data:
(a) IPMB01_IDN = 49464572 in the 2018 Q1 inpatient release
(b) IPMB01_IDN = 49428583 in the 2017 Q4 inpatient release
The issue arose due to a mismatch between the hospital-supplied patient ZIP code and the hospital-supplied patient city, for out-of-state patients, resulting in two identical records for the same IPMB01_IDN, except for the geocode field; one of the two distinct records has a correctly assigned geocode value, while the other instance can be deleted.
Users should take note and exclude the following records from all applicable files received:
(a) For IPMB01_IDN = 49464572, the record with IPML22_GEOCODE = 44055 should be deleted
(b) For IPMB01_IDN = 49428583, the record with IPML22_GEOCODE = 44045 is the improper one and can be deleted

1 5 New Release File: This release contains a new file: OP61_Narrow. This file contains the same detail information as the existing OP61 file. However, it has been restructured. Rather than each row having three sets of fields documenting revenue codes, HCPCS codes, etc., the OP61_Narrow format only has a single set of fields. So, if an encounter has 2 records with all fields populated on the OP61 table with OP6102_SequenceNumbers 1-2, these would appear as 6 records on OP61_Narrow with OP6102_SequenceNumbers 1-6. The MHDO will continue to supply the OP61 information in both formats for reasons of backwards compatibility. 1/1/2017 12/31/2017
2 5 Hospital Specific Notes:
Calais Regional Hospital (200055) – lower counts in February 2017 due to loss of physicians and services at hospital.

Mount Desert Island Hospital (200038) – lower count in February 2017 due to few of the high-volume providers on vacation during that month, having significant impact on their volume.

Pen Bay Medical Center (200063) - lower record count for Pen Bay physician clinic data is due to the change in EMR vendors. The new system includes multiple procedures in one encounter record; whereas previous did not.
1/1/2017 12/31/2017
3 5 Missing Data:
Maine Coast Physician Offices (200072) – Missing Q4 2017 data due to unresolved issues with their data vendor. MHDO is working with submitter in hopes that the missing Q4 2017 data will be submitted and included in the next release of hospital outpatient data.

Mount Desert Island Health Centers (200086) – Missing data due to issues with new vendor and system. MHDO is working with submitter in hopes that the missing Q4 2017 data will be submitted and included in the next release of hospital outpatient data.

Dorothea Dix Psychiatric Center (200057) – Dorothea Dix reported to MHDO that they do not have final bills for Q4 2017 and will include any Q4 2017 outpatient encounters in the next reporting cycle.

7 10 This release contains July – September (Q3) 2017 Hospital Inpatient Encounter data. It contains inpatient encounter data for all Maine hospitals required to submit according to MHDO Rule Chapter 241. Data issues to note in this release:

1) As of August 2017, Calais Hospital no longer delivers babies.

2) Emergency Department (ED) visits – MHDO’s methodology for flagging ED visits remains unchanged – visits that have a revenue code of 0450, 0452, 0456, or 0459 are flagged and considered ED visits. In this release we noticed around a 50% drop in flagged ED visits for two facilities in the 3rd quarter – Calais Hospital and Mayo Hospital. Note: the number of total encounters at these facilities remained consistent with historical counts. Both hospitals are Critical Access Hospitals with CPSI as their data vendor. Based on our research of these issues it appears that our methodology to flag ED visits as described above may not be catching ED visits at critical access hospitals for certain payers. What has come to our attention from these two CAH’s that is impacting our ability to apply our flagging methodology is a billing practice referred to as “split” billing. Feedback from these hospitals is as follows:

Calais Hospital: MHDO’s methodology described above is only flagging non-Medicare patients with ED visits at Calais Hospital. The reason for this is as described by Calais Hospital: All Medicare accounts at our facility “split” off to bill the ED separately, meaning any inpatient with Medicare will not show any ED charges (Rev codes in the 0450’s) on their Inpatient record. Instead there will be a separate record (ED only) created after discharge to bill the ED portion of the stay.

Mayo Hospital: MHDO’s methodology described above is only flagging non-Medicare, MaineCare, VA, Workers Comp and Medicare Replacement plans at Mayo Hospital.

MHDO/HSRI will discuss with CAH’s the best way to identify all ED visits regardless of the payer for future releases.

31 20 Outpatient Release 20: 2021 Q3 Hospital Specific Notes

Total Volume Quality Check: MHDO compares the hospitals encounter volume for each quarter against the hospitals previous quarter of data and identifies changes equal to or greater than 20% in the Release Notes; and includes a statement from the hospital for the variation.

Increases in Volume: None

Decreases in Volume:

Northern Light Mercy Hospital (200008) experienced a 30% decrease in 2021 Q3 compared to 2021 Q2. The hospital confirmed the accuracy of their reporting stating the decrease in volume is due to less Covid vaccinations given this quarter vs the prior quarter. Last quarter was a mass community effort for the Covid vaccination.

Northern Light C.A. Dean Hospital (200023) experienced a 32% decrease in 2021 Q3 compared to 2021 Q2. The hospital confirmed the accuracy of their reporting stating, less patients were seen during this quarter because there was a higher volume of Covid Vaccine Clinics done in Q2, then in Q3.

Northern Light Eastern Maine Medical Center (200033) experienced a 27% decrease in 2021 Q3 compared to 2021 Q2. The hospital confirmed the accuracy of their reporting stating they are trending back to the normal volume prior to covid outbreak.

Encounters Missing Primary Payer Volume Quality Check:

There are a few submitters that have encounters that are missing primary payer information; the percentage of missing primary care payer information for 2021 Q3 quarter is less than 0.1%.

Northern Maine Medical Center (200052): 1% of encounters are missing primary payer information. The hospital stated that the missing payer information is for encounters that are either self-pay or client billing. Client billing means the employer pays. For example, if an NMMC employee needs to test for COVID NMMC pays for it. The MHDO is working with the submitter to enter self-pay or client billing as payer names for these encounters in future submissions.

Maine Behavioral Health (200067) and Maine Medical Center (200009):

This release includes a resubmission of Q1 2021 outpatient hospital data for these two submitters. It was discovered that data from four Maine Behavioral Health departments were mistakenly reported in the Maine Medical Center files. Data users of data release version 18 are not missing any data for these entities, instead the facility identified in the data was not correct. The facility confirmed that the reason for the misidentification was due to the transition to a new EMR system on 2/27/21. The issue has been resolved and updated files have been submitted to MHDO.

22 18 Outpatient Release 18: 2021 Q1 Hospital Specific Notes

Total Volume Quality Check: MHDO compares the hospitals encounter volume for each quarter against the hospitals previous quarter of data and identifies changes equal to or greater than 20% in the Release Notes; and includes a statement from the hospital for the variation.

Increases in Volume

Maine Medical Center (200009) experienced a 24% increase in 2021 Q1 volume compared to 2020 Q4 volume. The hospital confirmed the accuracy with the following explanation: “Volume increase attributed to COVID vaccinations.”

Northern Light AR Gould Hospital (200018) experienced a 24% increase in 2021 Q1 volume compared to 2020 Q4 volume. The hospital confirmed the accuracy with the following explanation: “Higher volume is due to increase in Covid vaccines and Covid Labs. Volume is correct.”

Northern Light C.A. Dean Hospital (200023) experienced a 39% increase in 2021 Q1 volume compared to 2020 Q4 volume. The hospital confirmed the accuracy with the following explanation: “The volume of 13,663 for CAD Q1 2021 is correct. The increase volume is related to Covid-19 Vaccination and Covid-19 lab encounters. Covid-19 vaccination is a two shot series 21 days apart. Each patient receiving the two shot series generated two encounter numbers.”

Northern Light Eastern Maine Medical Center (200033) experienced a 36% increase in 2021 Q1 volume compared to 2020 Q4 volume. The hospital confirmed the accuracy with the following explanation: “The increased volume of 210,279 is correct (from 155,084 from the 4th Qtr. 2020). This increased volume is directly linked to COVID-19 vaccinations and COVID-19 lab encounters. Because the majority of the COVID-19 vaccinations are two-dose series, each of those patients receiving both shots generated two encounter numbers, thus accounting for the large volume increase during the first quarter of 2021.”

Spring Harbor Hospital (Maine Behavioral Healthcare) (200067) experienced a 75% increase in 2021 Q1 volume compared to 2020 Q4 volume. The hospital confirmed the accuracy with the following explanation: The main reason for the large increase in volume is that when they switched to the EPIC EMR (2/27/21) they began submitting data for outpatient services they provide at their other locations. It went from two to 56 locations in all that fall under the Maine Behavioral Health scope.

Stephens Memorial Hospital (200032) experienced a 21% increase in 2021 Q1 volume compared to 2020 Q4 volume. The hospital confirmed the accuracy with the following explanation: “Volume increase attributed to COVID vaccinations.”

Waldo County General Hospital (200013) experienced a 25% increase in 2021 Q1 volume compared to 2020 Q4 volume. The hospital confirmed the accuracy with the following explanation: “Volume increase attributed to COVID vaccinations.”

Decrease in Volume

New England Rehabilitation Hospital (200010) experienced a 24% decrease in 2021 Q1 volume compared to 2020 Q4 volume. The hospital confirmed the accuracy with the following explanation: “These numbers are correct. The inclement weather/threat of inclement weather and a decline in referrals combined to reduce our volume for Q1 2021.”
1/1/2021 3/31/2021
23 18 Self-Pay Volume Quality Check: MHDO compared the hospitals self-pay encounter volume for each quarter against the previous quarters submitted and flagged changes that are larger than historical volume.

Southern Maine Health Care (200019) 9% of encounters were Self- Pay for March 2021 with volume of 3,554 encounters, 5%-6% for Jan and Feb 2021 and 2020 most months with around 1,000 encounters.

Mount Desert Island Hospital (200038) 16% of encounters were Self-Pay for March 2021 with volume of 663 encounters, 7%-13% for Jan and Feb 2021 and 2020 months with 100-400 encounters.

Mid Coast Hospital (200044) 13% of encounters were Self-Pay for Jan 2021 with volume of 2,152 encounters, 7%-9% for Feb and March 2021 and 2020 months with 500-1500 encounters.

Encounters Missing Primary Payer Volume Quality Check: There are a few submitters that have encounters that are missing primary payer information; the percentage out of the total volume for 2021 Q1 quarter is less than 0.1%.

Northern Light Mayo Hospital (200066) 2%- 3% of encounters are missing primary payer information; these findings are consistent with what was observed in previous quarters.

Length of Stay Quality Check: The volume of encounters where the length of stay is greater than one, has increased for several hospitals. (Time frame between dates coded in the Statement Covers Period From field and the date in the Statement Covers Period Thru field). These encounters are primarily associated with administration of two-dose COVID vaccines. These facilities confirmed that rather than a patient having two separate services, they coded the two dose vaccines as recurring services (traditionally used for therapies, some lab, radiation therapy etc.) such that the start date was the first dose, and the second dose was the end date.

- Bridgton Hospital - 2021 Q1 18% of encounters, which is a change from an average of 3% in 2017-2020.
- Rumford Hospital - 2021 Q1 for 20% of encounters, which is a change from an average of 5% in 2017-2020 quarters.
- Central Maine Medical Center – 2021 Q1for 10% of encounters, which is a change from an average of 2% in 2017-2020 quarters.
1/1/2021 3/31/2021
24 18 Location of Service (LOS)

As the COVID-19 vaccine became available in 2021 Q1, many hospitals opened new vaccine clinic locations. As a result, users will see an increased number of new Location of Service (LOS) codes and descriptions available in this release. For example, Northern Light Eastern Main Medical Center (200033) had over 50,000 encounters take place at the City of Bangor-Bass Park COVID testing location. Maine Medical Center (200009) had over 40,000 encounters take place at a COVID vaccination clinic at the former Scarborough Downs harness racing track.

20 17 2019 Outpatient Release 17 – Mount Desert Island Resubmission

This release contains January - December 2019 Hospital Outpatient Encounter data for Mount Desert Island Hospital (200038).
Mount Desert Island recently corrected an error in their reporting of clinic data. They have resubmitted their 2019 data to now include encounters from 6-7 health centers owned by MDI hospital. As a result, the volume of outpatient encounters reported to the MHDO has increased from approximately 41,000 encounters to approximately 86,000 encounters. The resubmitted volume is consistent with the approximately 84,000 encounters in 2020.
1/1/2019 12/31/2019
15 12 2020 Outpatient Release 12

This release contains January - December 2020 Hospital Outpatient Encounter data for all Maine hospitals required to submit data to the MHDO according to Rule Chapter 241, Uniform Reporting System for Hospital Inpatient and Hospital Outpatient Data Sets.
1/1/2020 12/31/2020
16 12 2020 Outpatient Release 12 Hospital Specific Notes

Total Volume Quality Check: MHDO compares the hospitals encounter volume for each quarter against the hospitals previous quarter of data and identifies changes equal to or greater than 20% in the Release Notes; and includes a statement from the hospital for the variation.

In 2020, many facilities experienced considerable volume decreases in Q2, gradual increases in Q3, and volumes nearing normal again in Q4. Each facility confirmed the accuracy of the data submitted, and most have indicated that the reduction or increase in encounters is in response to the COVID-19 pandemic. In an effort to streamline the release notes, we have not listed every facility and their volume changes by quarter in 2020 that are due to the pandemic. However, we have noted two facilities and their volume changes in 2020 below.

Mount Desert Island Hospital (200038): MDI recently corrected an error in their reporting of clinic data. As a result, the volume of encounter records more than doubled in 2020 compared to 2019 (84,190 encounters reported in 2020 versus 41,396 encounters reported in 2019). MDI has since resubmitted 2019 data which can be made available to data users if interested.

New England Rehabilitation Hospital (200010) confirmed that they had a 46% increase in Q1 due to discharging patients in March due to the pandemic. Q2 volume decreased 99% (No encounters for April or May and 4 encounters reported for the month of June) due to the complete shutdown of outpatient therapy services mid-March thru beginning of July.

ED Volume Quality Check: MHDO compares each hospital's 2020 quarterly ED % against their prior year's overall ED %. Differences of 10 percentage points or more are identified in the Release note; and includes a statement from the hospital for the variation. Notes for identified facilities are below.

Mount Desert Island Hospital (200038): ED visits decreased in 2020. The facility has confirmed the accuracy with the following explanation: “We had a decrease in 2020 of ED visits due to COVID and travel restrictions. Our ED volume typically increases during the summer months due to International travel (Cruise ships, etc.) and domestic travel (personal vehicles and tour buses). We did not have any of that last year.”

Primary Payer Quality Check: MHDO compares the number of records per quarter missing OP3009 Payer Name (Primary) against the total number of records per quarter and identifies percentages equal to or greater than 1% in the Release Notes; and includes a statement from the hospital to explain the missing information.

Mayo Regional Hospital (200066), 2% of 2020 records are missing the primary payer information. This facility has confirmed the accuracy with the following explanation: “These files look like employee health visits. The payor for these is the employer the patient works for.” MHDO is working with the hospital to have information included in OP3009 in future submissions so that MHDO can code these values as the ‘11’ Other payer category.

17 12 Enhanced Deidentified Person ID

The enhanced deidentified MHDO-assigned replacement Person ID is meant to be unique for a given person regardless of hospital. This field appears in the base release layout as OPMB10_PersonID and contains integer values.
1/1/2020 N/A
18 12 Enhanced Provider ID

The enhanced MHDO-assigned replacement Provider ID is a single integer identifier that is assigned to a provider (regardless of whether that provider is acting as an operating provider, an attending provider, or a billing provider) on a given encounter. Each MHDO assigned provider ID is associated with no more than one NPI.

For data releases that include Provider Identifiable data as outlined in Chapter 120, the following revised MHDO-assigned replacement fields are included: OPMB11_Attending_ProviderID, OPMB12_Operating_ProviderID, OPMB13_Billing_ProviderID.

To support the enhanced MHDO-assigned replacement Provider ID, authorized data users will receive an updated support table vwSupport_Provider_Details beginning with this release. The table will provide one row for each Provider ID with provider details as authorized under Chapter 120 for release, such as NPI and, for data users authorized to receive provider identifiable information, provider name. A text file named vwSupport_Provider_Details_Layout with the layout of this file will also be included in this release.
1/1/2020 N/A
19 12 Facility Information Update

Upon a review of the Hospital System column (ifHospitalSystem) in the Support Facilities table, MHDO uncovered some missing information. This only impacts the support table used to identify hospitals and the systems they are affiliated with, not the data themselves. The following hospital submitters have corrected hospital system values as follows:

Penobscot Valley Hospital (200062): change from “Maine Health” to blank
MaineGeneral Medical Center Augusta (200015): change from blank to “MaineGeneral Health”
MaineGeneral Medical Center Waterville (200039): change from blank to “MaineGeneral Health”
New England Rehabilitation Hospital (200010): change from blank to “MaineHealth”
Franklin Memorial Hospital (200037): change from blank to “MaineHealth”
Mid Coast Hospital (200044): change from blank to “MaineHealth”
Mayo Regional Hospital (200066): change from blank to “Northern Light Health”
St. Joseph Hospital (200001): change from blank to “St. Joseph Healthcare”
St. Mary's Regional Medical Center (200034): change from blank to “St. Mary's Health System”

As a result of the changes listed above, the following submitters, affiliated with one of the facilities mentioned, also needed to have their hospital system value updated:
MaineGeneral Physician Offices (200070): change from blank to “MaineGeneral Health”
LSS - Franklin-Physicians Offices (200092): change from blank to “MaineHealth”
ECW - Franklin Physician Offices (200096): change from blank to “MaineHealth”

11 11 2019 Outpatient Release 11
This release contains January - December 2019 Hospital Outpatient Encounter data for all Maine hospitals required to submit data to the MHDO according to Rule Chapter 241, Uniform Reporting System for Hospital Inpatient and Hospital Outpatient Data Sets.
1/1/2019 12/31/2019
12 11 New Release Field: The base release layout now includes a new field, OP4006_Place_of_Service, which contains CMS codes indicating the specific type of professional bill. 1/1/2019 12/31/2019
13 11 Updates to the Location of Service support table
Starting with the 2019 Outpatient release, the vwSupport_LOS_Codes table includes a new field, Start_Date. In the 2019 release this field displays the date when the respective row was loaded to the support table in the data warehouse. In next year's 2020 release this field will display, where provided, a date collected directly from submitters about the date the location began providing services. Additionally, MHDO has begun collecting a date the location moved or stopped providing services. The respective start and end dates are passed on to data users in the LOS_Description field. A date value of N/A signifies that the submitters left the respective information unspecified; as per submission guidelines, end dates with the N/A value indicate that the LOS code is still active.

14 11 Hospital Specific Notes:

Total Encounters-Volume
Total Volume Quality Check: We compared the volume for 2019 Q1-Q4 quarters against their previous quarter (each of 2018 Q1 through 2019 Q3, respectively) and flagged potential issues if the volume changes are equal to or greater than 20%. Notes for flagged facilities are below.

ECW - Franklin Physician Offices (200096): The MHDO assigned provider ID for ECW-Franklin Physician Offices of 200096 was terminated beginning with Q2 2019 data submission. As of Q2 2019 all data for ECW-Franklin Physician Offices has been consolidated into the Franklin Memorial Hospital MHDO ID 200037.

Also, similar to what was noted for the CY 2018 outpatient release for Franklin Physician Offices, there is a relatively high volume of partial duplicates (47% of the total 18,083 records from this submitter) for their Q1 2019 data, meaning that they share the same patient information (date of birth, gender, etc.), statement covers period from and thru dates, Medical Health Record Number, discharge status and some other key fields. We continue to recommend, for records submitted with MHDO ID 200096 (note, this is their final submission under this ID), that users develop queries tailored to look across encounters in order to retrieve details for unique outpatient visits.

Franklin Memorial Hospital (200037): Consistent with what is stated above, starting with Q2 2019, the ECW- Franklin Physician Offices (200096) data is being reported with the hospital data stream (200037). As such the total number of outpatient encounters reported under the MHDO ID 200037 has increased in 2019, compared to 2018.

Mayo Regional Hospital (200066): The volume for Q1 increased (compared to 2018 Q4). The volume increase for 2019 OP data is due to it being the first-year clinic data has been submitted to MHDO.

Northern Light Inland Hospital (200041): The 2019 encounter volume is lower than in 2018. As noted in the 2018 release, in Q4 there was a decrease in Inland Hospital’s outpatient encounters due to the implementation of a new EMR system, where ancillary services began to be billed under one patient account rather than separate accounts/encounters.

Northern Light Mercy Hospital (200008): In December 2018, after switching to a new EMR system, the affiliated clinic data (previously submitted separately under 200078) began to be submitted with this hospital outpatient data MHDO ID 200008. As a result, the 2019 volume for 200008 is higher than the 2018 volume but the total 2019 volume decreased when compared to what was previously submitted under the two MHDO IDs previously used. There are three main reasons. The first is that the overall patient census on the hospital side has been declining since January for both surgical, PT/OT and ancillary services. The second is that the facility’s practices were still not booking at 100% capacity until mid-March due to the EHR implementation from December 2018. The third reason is that their ENT practice went from 4 providers down to one until May 2019, this practice is just beginning to get back up to 100% volume.

ED Volume

Mount Desert Island Hospital (200038): There is an increase in ED visits in CY 2019 compared to CY 2018, specifically the increase occurs in Q3 2019. MDI has stated that this increase is due to their summer tourism volume.

Encounters Missing Primary Payer Information

Mayo Regional Hospital (200066): Approximately 2% of their outpatient encounters are missing primary payer information in each quarter of 2019. This share stands out especially because prior to 2019 (2016-2018) there were no encounters missing primary payer information. Mayo provided information on the missing primary payer information confirming that “all these records are associated with the Workwise program which is an occupational health program for employers and for employees of businesses in the area. There is no insurance listed because the hospital bills the employer, or the “client”, not an insurance company”. MHDO is working with the hospital to determine how to code these claims in future submissions.

8 7 Hospital Specific Notes:

Total Encounters-Volume

St. Joseph Hospital (200001) and St Mary’s Regional Medical Center (200034): We observed a significant change in the volume of encounters reported in Q2 2018. When we asked the hospital about this change they reported the following:
"What we think we’re seeing for the differences between the systems (Meditech vs. EPIC) is due to provider billing. For some provider billing purposes in the legacy system a separate visit/encounter was created for the same date as the hospital outpatient visit. In our new EPIC system, we do not have to take those additional steps for provider billing. The difference seen in the counters in the files once we switched over to EPIC was from changing over at the middle of the quarter, we went live on EPIC, May 13th."

Northern Light Mercy Outpatient Provider Clinics (200078): In December 2018 Mercy switched to a new EMR system and began submitting their outpatient clinic data (previously submitted separately under 200078) with their 200008 hospital outpatient data stream. During their EMR conversion the practices were only booking at 25% volume for the month of December and experienced decreases in patient visits hospital wide.

Northern Light Inland Hospital (200041): In Q4 there was a decrease in Inland Hospital’s outpatient encounters due to several factors. A new EMR was implemented, patient visits decreased during this system change over, and ancillary services began to be billed under one patient account rather than separate accounts/encounters.

York Hospital (200020): We observed an increase in volume of encounters in October 2018. The facility confirmed that the volume for the year is correct, but some discharge dates have shifted due to a malfunction in the automatic discharge setup and cannot be changed. While the information reported is substantially correct, some of the monthly volume of discharges by discharge month between October and December will vary, most of which is due to much higher volumes in the month of October vs. December. Length of stay calculations are impacted as well.

Payer Category Observations: Self Pay (Primary Payer only)

St. Joseph Hospital (200001): reported a monthly average of 167 self-pay encounters in 2017, which increased to an average of 495 in 2018. Hospital explained that prior to the change to the new EMR, they had self-pay and charity care separate. Now the two are under self-pay only; therefore, increasing the total.

Other Notes:

Northern Light Inland Hospital (200041): Because of financial hardship per the request of Northern Light, MHDO allowed Inland Hospital to submit their 1/1/2018 through 10/31/2018 physician practice data in the pre-2018 Chapter 241 format. Note: The pre-2018 format did not include the following five elements and therefore are not included in these data.

OP2018 Patient Country Code
OP2019 Patient Last Name
OP2020 Patient First Name
OP2023 Patient Address Line
OP4006 Place of Service

ECW - Franklin Physician Offices (200096): Records from this submitter have a substantial proportion (51%) of records that have been preliminarily detected as partial duplicates, meaning that they share the same patient information (date of birth, gender, etc.), statement covers period from and thru dates, Medical Health Record Number, discharge status and some other key fields. For the vast majority of these records, though not all, there are different values in fields such as service codes and corresponding charge amounts, or provider NPIs. As a rule, any records that are initially detected as partial duplicates where variation is observed in terms of the OP9004 Total Ancillary Charges or provider NPIs are not furthered processed as partial duplicates in our system. Given the findings for this submitter’s 2018 records, the majority of their 2018 records are included in this release. These records are equally distributed between the four quarters of CY2018. We recommend, for this particular submitter, that users develop queries tailored to look across encounters in order to retrieve details for unique outpatient visits.

9 8 New Payer Category Codes – Patch File for Outpatient data prior to Q1 2018.

Release 8 contains Hospital Outpatient Encounter records that were released prior to Q1 2018.This release contains encounter rows that have had at least one of the following fields updated: OPMPY20_PAY1, OPMPY21_PAY2, OPMPY22_PAY3. The MHDO periodically reassesses payer names that were assigned Payer Category Codes of ‘99’ or null in previous releases to determine whether newly received data have brought the number of encounters associated with these names above the “10 or more encounters” threshold. Previously unassigned payer names found to be above this threshold are assigned a Payer Category Code and encounters that previously were coded with a null or ‘99’ are then updated with the new code. Enclave users and new data applicants who request data extracts in this date range will have access to the updated values.

A patch file with these new Payer Category Codes is available by request for current data users who previously received data extracts in this date range.
1/1/2009 12/31/2017
10 9 Previously Missing 2017 Outpatient Data, Now Available – Patch File

2017 Outpatient data are now available for the following facilities:
Northern Light Maine Coast Physician Offices (200072) – New data for Q4 2017
Mount Desert Island Hospital (200038) – New data for Q2 & Q4 2017
4/2017 12/2017
1 5 New Release File: This release contains a new file: OP61_Narrow. This file contains the same detail information as the existing OP61 file. However, it has been restructured. Rather than each row having three sets of fields documenting revenue codes, HCPCS codes, etc., the OP61_Narrow format only has a single set of fields. So, if an encounter has 2 records with all fields populated on the OP61 table with OP6102_SequenceNumbers 1-2, these would appear as 6 records on OP61_Narrow with OP6102_SequenceNumbers 1-6. The MHDO will continue to supply the OP61 information in both formats for reasons of backwards compatibility. 1/1/2017 12/31/2017
2 5 Hospital Specific Notes:
Calais Regional Hospital (200055) – lower counts in February 2017 due to loss of physicians and services at hospital.

Mount Desert Island Hospital (200038) – lower count in February 2017 due to few of the high-volume providers on vacation during that month, having significant impact on their volume.

Pen Bay Medical Center (200063) - lower record count for Pen Bay physician clinic data is due to the change in EMR vendors. The new system includes multiple procedures in one encounter record; whereas previous did not.
1/1/2017 12/31/2017
3 5 Missing Data:

Maine Coast Physician Offices (200072) – Missing Q4 2017 data due to unresolved issues with their data vendor. MHDO is working with submitter in hopes that the missing Q4 2017 data will be submitted and included in the next release of hospital outpatient data.

Mount Desert Island Health Centers (200086) – Missing data due to issues with new vendor and system. MHDO is working with submitter in hopes that the missing Q4 2017 data will be submitted and included in the next release of hospital outpatient data.

Dorothea Dix Psychiatric Center (200057) – Dorothea Dix reported to MHDO that they do not have final bills for Q4 2017 and will include any Q4 2017 outpatient encounters in the next reporting cycle.
1/1/2017 12/31/2017
4 5 Closings:
Riverview Psychiatric Center-Medication Management Clinic (200056) –Riverview notified the MHDO that their Medication Management Clinic closed January 2017, so beginning with Q1 2017 there will be no outpatient claims to submit.

Information Regarding 2012 Outpatient Data Release of 8/15/14:

In spite of the extensive internal and external QC that is performed on data prior to release, an issue involving duplicate records has only now been uncovered in the Maine 2012 Outpatient data which was released in August of 2014. In total, there were 49,985 records that appear more than once, most often under two different hospitals. This represents 0.8% of the total release data.

The duplicate system ID file contains a list of record ID (Sysid) that need to be removed from the release data to correct for this error. Any record on either the Encounter or Detail table that has a Sysid on the list should be removed from any analysis of the data.

Removing these records from the previously sent data seems to be the most expedient way to resolve this issue, as users will have already loaded the data into their systems. Any user that would prefer to receive a complete replacement of the release files should contact the MHDO.

Going forward an additional check will be added to the internal QC process to identify and remove any exact duplicate records prior to release.

If you have any questions or concerns, please contact Karynlee Harrington at 207-446-0890.

Outpatient Hospital Encounter Data for CY 2012 were released 8/15/2014. As we continue to work on improving our documentation we provided users with several documents as part of the release.
