Medical prior authorization: the other “prior auth”

In U.S. healthcare, prior authorization is a health plan's approval before it will cover certain care. It has nothing to do with a payment-card hold — this page exists because the same two words cause constant confusion.

What it means

Medical prior authorization (also called pre-certification or pre-approval) is a health plan's decision that a prescription, test, procedure, treatment, or hospital service is covered under the plan — often made before the care happens. If the plan requires authorization and none is obtained, the plan may refuse to pay, leaving the patient with the bill. The card-hold kind of pre-authorization reserves money on a bank card; the medical kind approves coverage. Different industries, different rules, same shorthand.

How to check whether you need it

If a prior authorization is denied

Ask for the reason in writing, the deadline to respond, and the insurer's appeal or grievance process. Your care team may be able to supply missing clinical information, request a peer-to-peer review, or discuss alternatives the plan will cover. Denials are frequently documentation problems rather than final answers, so treat the first “no” as the start of a process, not the end of one.

Informational only. Medicare, Medicaid, employer-sponsored, and individual health-plan rules differ, and this page does not provide medical or insurance advice and does not list or endorse providers. For your situation, rely on your plan documents and your care team.
