I have a P2P with an MD from a commercial insurance agency. They initially denied SCS trial for a patient. The patient has a plethora of pain issues most notably low back pain, lumbar spondy, radic, numbness/tingling in feet, neuropathy, to name a few. They've failed conservative therapy including ESI, RFA, PT, meds. Told not to be a surgical candidate. This insurance has listed indications for SCS as: Failed Back Surgery, CRPS or Critical Limb Ischemia. They don't really fit nicely into any of these. In reality, can I expect them to approve SCS for a non-approved indication if I argue for it? Or are P2P's only to see if a patient does actually fit into one of their approved categories? For example, maybe I should argue during the P2P that they do have early signs of CRPS although that wasn't the initial working diagnosis that was documented when we submitted for auth. In other words, what's the best way to get this approved?
