Choose the source that answers your question

Start with the member’s named plan or current card. Check that the publisher, program and edition match before applying a document. An employer-specific example is useful for recognizing a formulary family, but does not describe every member administered by the same PBM.

Use the RX BIN lookup for routing identifiers and the reject-code reference for a returned code. Neither substitutes for the complete payer response. Public documents may move or require a portal sign-in; use the publisher’s current document index if a saved PDF is no longer available.

FAQ

Questions worth asking.

Is there one national pharmacy formulary?

No. Commercial PBM lists can vary by employer and plan, Medicare Part D plans have their own formularies, and Medicaid preferred drug lists vary by state and sometimes by managed-care plan. Use the source that matches the coverage context, then confirm the member-specific benefit.

Does a public formulary prove that a claim will pay?

No. Public lists may be templates, abbreviated lists, or state-level references. They do not replace the member's current card, eligibility response, plan portal, benefit documents, or live claim result.

What should I check when a drug is not on a formulary?

Confirm that the list and effective date match the patient's plan, then check the plan's coverage policy, preferred alternatives, prior-authorization or exception process, and the current claim response. Do not infer that an omitted drug is universally excluded.

What is the difference between a formulary and a preferred drug list?

A formulary is a plan's covered-drug list, often organized by tier and restrictions. A preferred drug list identifies products a program prefers, usually for lower cost or simpler authorization. The terms overlap in everyday use, but the governing plan or state program defines the actual coverage and rules.
