I have a denial from Aetna for a pain management procedure. We billed 64635 & 64636 for RFA lumbar. Aetna is denying as payment is inclusive in payment for other procedure and procedure code incidental to primary procedure not submitted for adjudication. This is the primary procedure. The patient had the injections done prior to the RFA. This is the first RFA performed, so I'm not sure if a modifier would be needed.
