Methodology for Rx Costs and Utilization

The information in these reports represents the most recent 12 months of available data as of the date of publication. The data were extracted from pharmacy claims data in the MHDO All-Payer Claims Database (APCD) for medications prescribed July 1, 2019 – June 30, 2020. The reports focus on prescription drugs purchased at a retail pharmacy, including mail-order; they do not include medications that appear on medical claims and those purchased over the counter without a prescription.

  • NDC and Drug Name – Each analysis is conducted at the level of the 11-digit National Drug Code (NDC), a unique, three-segment number that serves as a universal product identifier for drugs. All pharmacy products with an NDC are included in the analyses. The NDC identifies the chemical compound in the drug, the labeler (usually the manufacturer), and the type of packaging, for example pill or liquid form.
  • Drug Class(es) – The reports use the American Hospital Formulary Service (AHFS) Drug Information to provide Drug Classes, the contextual information on the types of therapies each drug is prescribed for.
  • Number of Prescriptions – Calculated across all prescriptions for a specific drug, regardless of variation in the quantity dispensed or the number of days of supply.
  • Number of Prescription Users – Count of individuals with at least one pharmacy claim for the drug during the reporting period. Note that the number of prescription users is not comparable between Version 2 and Version 3 due to implemented improvements in tracking individuals across insurance changes.
  • Cost –Total dollar amount insurance companies and insured individuals paid a pharmacy for prescriptions of the drug throughout the State.
  • Cost Per Prescription – Total dollar amount insurance companies and insured individuals paid a pharmacy for prescriptions of the drug divided by the number of individuals that filled the prescription during the year.
  • Increase – Data from the previous 12 months were analyzed to ascertain year-over-year cost increases.
