How to appeal a Prior Authorization denial

A prior-authorization denial means the payer says the required pre-approval wasn't obtained before the service. It's common, and a large share are recoverable.

Common code: CARC 197 (precert/authorization absent)

Why payers issue it

  • Authorization was required and not obtained, or obtained for the wrong code
  • It was an emergent or add-on service where auth wasn't practical
  • The auth existed but wasn't linked to the claim correctly
  • The payer's own records of the auth are wrong

What overturns it

  • Pursue a retroactive authorization where the payer allows it
  • Show the service was emergent or that auth wasn't actually required for the code/plan
  • Provide the existing auth number and tie it to the claim
  • Demonstrate medical necessity to support a retro-auth appeal

Worth appealing? Prior-auth denials feel like a dead end, but retro-auth and payer-error appeals recover a meaningful slice, especially on emergent and add-on services.

Common questions

How do I appeal a Prior Authorization denial?

A prior-authorization denial means the payer says the required pre-approval wasn't obtained before the service. It's common, and a large share are recoverable. To overturn it: pursue a retroactive authorization where the payer allows it; show the service was emergent or that auth wasn't actually required for the code/plan; provide the existing auth number and tie it to the claim; demonstrate medical necessity to support a retro-auth appeal. The key is matching the documentation to the payer's own rule for prior authorization denials.

Is a Prior Authorization denial worth appealing?

Prior-auth denials feel like a dead end, but retro-auth and payer-error appeals recover a meaningful slice, especially on emergent and add-on services. A no-risk recovery service makes it easy to find out, you only pay on what's actually recovered, so there's no cost to working the ones that are winnable.
