GHP Family plan formulary updates

Health insurance plan formularies are regularly updated, like when new drugs are added or a drug is recalled.

These changes are listed in our GHP member newsletters, or you can check this page whenever you’d like.

Formulary changes

If we remove drugs from our formulary, or add prior authorization, quantity limits and/or step therapy restrictions on a drug or move a drug to a higher cost-sharing tier, we must notify affected members of the change (30 days for employer coverage and GHP Family; 60 days for other plans) before the change becomes effective.

Safety concerns

Drugs declared unsafe by the FDA or withdrawn by the manufacturer are immediately removed from the formulary, and affected members are notified.

Prior authorization

Some drugs require prior approval from GHP Family. Your prescriber must get this approval before the prescription can be filled. GHP Family will not cover the drug without approval.

If prior authorization is needed:

Option 1

If your medication isn’t on the Statewide Preferred Drug List or GHP Family formulary, you can share the lists with your doctor. They can tell if you if there’s an alternative that will work for you.

Call GHP Family Pharmacy Customer Service at 855-552-6028 or 570-214-3554 (PA Relay 711).

Hours:
Monday, Tuesday, Thursday, Friday: 8 a.m. – 7 p.m.
Wednesday: 8 a.m. – 8 p.m.
Saturday: 8 a.m. – 2 p.m.

Option 2

Your doctor can ask GHP Family to approve your current drug through a prior authorization. See our Geisinger policy.

Specialty medications and pharmacy options

With GHP Family, you have access to the Navitus Specialty Pharmacy Network, allowing you to choose any specialty pharmacy in the network.

Out-of-network pharmacies can be used if:

  • The medication isn’t available at a network pharmacy due to "limited distribution" by the manufacturer
  • A network pharmacy can’t provide the medication in time to prevent harm
