Nerve allograft (Avance) is medically necessary for repair of short-to-medium sensory nerve gaps of 30 mm or less in the upper extremity, and CPT 64912 and 64913 are covered when those selection criteria are met. Nerve allograft for motor nerve repair, long gaps over 30 mm, large-diameter nerves, lower extremity reconstruction and all other indications not noted as medically necessary is experimental, investigational or unproven. Sural, cavernous and genitofemoral nerve grafts during radical retropubic prostatectomy, collagen and synthetic or xenograft nerve wraps and conduits for all indications, nerve wrapping for compression neuropathy, and vascularized nerve grafts for a nerve gap are also listed as not covered.

Nerve Grafting and Reconstruction: Selected Indications (CPB 0416, reviewed 2025-06-09)
Aetna's Clinical Policy Bulletin 0416 sets the medical necessity rules for nerve grafting and nerve reconstruction.

Collagen conduits and synthetic or xenograft nerve grafts, including the AxoGen, Integra, NeuraGen, NeuraWrap, Neuromatrix and NeuroMend products, are experimental, investigational or unproven for all indications, and so are sural, cavernous and genitofemoral nerve grafts during radical retropubic prostatectomy, nerve wrapping for compression neuropathy, cross-palm nerve grafting for ulnar neuropathy, vascularized nerve grafts, intra-operative electrical stimulation of peripheral nerves in the upper extremity, and phrenic nerve reconstruction for diaphragmatic paralysis (this does not apply to prompt repair of acute phrenic nerve transection due to trauma or surgery).
