Search for a covered drug

Use the formulary search form to find a covered drug by generic or brand name, or view all drugs within a category.

Filling prescriptions

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.

Pharmacy for specialty medications

Call Member Services, your doctor, or Alphascript. To avoid delays in filling your prescription, call Alphascript on the day that you receive your prescription (before you leave your doctor’s office or clinic, if possible).
