AAAC Reimbursement for Fee-for-Service Pharmacies


The Oregon Health Authority (OHA) pays for Oregon Health Plan fee-for-service prescriptions using Average Actual Acquisition Cost (AAAC) rates.

  • The goal of the model is to establish a transparent, timely and accurate pharmacy reimbursement system.
  • AAAC rates are based on the actual cost (invoice) to the pharmacy for the drug dispensed plus a statistically validated dispensing fee.

Non-disclosure agreements

If your pharmacy would like a non-disclosure agreement (NDA) with OHA for information shared through the pricing and volume surveys conducted by Myers & Stauffer, LC:
  • Contact OHP Pharmacy Program (fax 503-947-1119).
  • The agreement will be executed and returned to you as soon as possible.
You can also view a copy of the state's NDA with Myers & Stauffer.
