Health Insurance Prior Authorization: What It Means and How to Prepare
Learn what prior authorization means, why it is not a payment guarantee, what information may be required, and how to track or appeal a decision.
Prior authorization—also called preauthorization or prior approval—is a plan requirement to obtain a coverage decision before certain services, drugs, equipment, or facilities are used. HealthCare.gov warns that preauthorization is not a promise that the plan will pay the claim.
Why plans require it
A plan may review whether the requested item is covered, medically necessary under its criteria, delivered in the correct setting, or preceded by required alternatives. Requirements depend on the exact plan, service, diagnosis, provider, and date. A new plan year or treatment change can trigger a new review.
Confirm responsibility
The treating provider often submits clinical records, procedure or drug codes, diagnosis information, prior treatments, and supporting notes. The member should still confirm that the request was sent, received, assigned a reference number, and decided before the service when possible. Out-of-network providers may have different obligations.
Information checklist
- Exact plan and member information through a secure channel
- Ordering and rendering provider names and network status
- Service, drug, equipment, or facility code
- Expected date and place of service
- Clinical documentation requested by the plan
- Reference number, submission date, status, and decision
- Written approval or denial and the effective authorization window
Why approval still may not equal payment
The member must still be eligible on the service date. The service must match the authorized code, provider, setting, quantity, and time window. Deductibles, copays, coinsurance, exclusions, benefit limits, coordination of benefits, and final claim facts also apply.
If a request is denied or delayed
Read the written notice for the reason, evidence used, correction process, appeal deadline, and urgent-review option. Ask the provider whether missing information or a different code caused the problem. Follow the plan’s internal appeal and external-review instructions when applicable. State and federal procedures differ.
Urgent care
A plan may have an expedited process when delay could seriously affect health under applicable criteria. The treating clinician and plan determine whether the request meets that standard. Do not delay emergency care to wait for an ordinary authorization; contact emergency services and the plan as soon as reasonably possible.
