How to obtain a prior authorization

Begin by confirming that the specific service requires authorization for the specific plan, using the payer's current policy rather than an assumption or a stale list. Which services require authorization varies by payer and plan and changes, so the only reliable answer is the current one from the payer.

At the same time, confirm coverage is active for the planned service date. An authorization is of no use if coverage is not in force when the service is delivered, and the two front-end checks are naturally run together.

Build the request around what the payer's criteria require it to establish: the specific service, the units or visits, the planned dates, the ordering and rendering providers, and the clinical documentation that supports medical necessity. Draw the clinical evidence from the record; never shape it to fit a criterion it does not actually meet.

Where the plan applies step therapy or specific coverage criteria, address them directly — document the prior trials or the basis for an exception — rather than leaving the reviewer to infer them.

Submit through the payer's required channel and select the correct standard or expedited pathway for the clinical situation. Record the submission date, channel, and any confirmation number so the request can be followed to a decision.

Track each request against the payer's stated timeframe rather than a generic one. If the payer signals an intent to deny on medical-necessity grounds, a peer-to-peer review is often the fastest way for the ordering provider to present the clinical rationale directly.

An approval is not the finish line. Record the authorization number, the approved units, and the approved date range, and make sure the eventual claim falls within all three. An approval for one service, a set number of units, and a date window does not cover a different service, more units, or dates outside it.

Reporting the authorization number where the payer's billing instructions require it is what lets the payer match the claim to the approval — so the reconciliation step is part of getting paid, not an afterthought.
