Senate Bill 819 (2001) created the Practitioner-Managed Prescription Drug Plan (PMPDP). The PMPDP requires the Oregon Health Plan (OHP) to maintain a list of the most cost-effective drugs to prescribe for fee-for-service members. This list is called the Preferred Drug List (PDL).
Drugs not listed on the PDL are "non-preferred" drugs.
- Non-preferred physical health drugs require prior authorization (PA).
- Non-preferred mental health drugs do not require PA.
