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

Most of the time, your  drugs are covered only if they are filled at HPSM network  pharmacies.

If your prescription is denied at the pharmacy, call your doctor. Your doctor will need to ask for pre-approval from HPSM. They can do this by filling out the Pharmacy Prior Authorization Request Form and the Pharmacy Prior Authorization Request Form and faxing it to 650-829-2045
