In general, your prescriptions are covered only if they are filled at HPSM network pharmacies.
If your prescription is denied at the pharmacy, call your doctor. Your doctor needs to request a prior authorization from HPSM to get coverage for that drug by filling out the Pharmacy Prior Authorization Request Form and faxing it to 650-829-2045. Your physician’s approval is required.
