HMO 90-Day Supply Program

The 90-day supply benefit program can save both time and money. With this program, members have the option of obtaining a 90-day supply of maintenance medications through a network of contracting retail and mail service pharmacies. Specific health care benefit plans and whether a medication is generic, formulary brand& or non-formulary brand will determine the amount paid. Using a generic or formulary brand medication can help save money.

If a change is made to an existing prescription and members need a refill immediately, they can provide the doctor with a Physician Fax Form so that he/she can send their prescription directly to the mail service pharmacy for them. Please note that the mail service pharmacy will only accept the fax prescription directly from the doctor's office.
