Criteria checklist

0 of 7 ticked
Indications
  • enumerated: no
  • description: Transection or avulsion of an extradural spinal/peripheral nerve (CPT 64772). Two practical uses: (1) endoscopic MEDIAL BRANCH transection (MBT) as a surgical alternative to facet radiofrequency ablation — supported by the same diagnostic logic (positive medial branch blocks); and (2) transection for intractable neuropathic/peripheral-nerve pain (e.g., painful neuroma, refractory neuralgia) as a late/last resort after failed less-invasive options. No NCD/LCD establishes criteria; document chronicity, the failed prior interventions, and the rationale.

Payor-specific notes

Endoscopic nerve transection (CPT 64772, transection/avulsion of other spinal nerve, extradural) has no NCD and no IN/KY LCD — Traditional Medicare adjudicates under §1862(a)(1)(A) R&N, and reimbursement is determined regionally by each MAC (claims often reviewed given the procedure is uncommon and invasive). The endoscopic application includes medial branch transection (MBT) as a surgical alternative to facet RFA; for that use, the facet diagnostic logic (positive medial branch blocks) supports medical necessity — see the facet-joint cell. CMS raised the 64772 MUE from 2 to 6 units effective 2026-01-01 (a utilization edit, not a coverage policy); MAC adoption timing varies. No peer LCDs exist. Confirm MAC posture before scheduling (needs_reverification).

Dot phrase

Lean narrative A&P attestation. `***` = fill-in. No NCD/LCD binds — Medicare R&N; document failed less-invasive options thoroughly (claims are reviewed).

.ENDONERVEMCARE
.ENDONERVEMCARE  [MEDIAL BRANCH TRANSECTION]

Assessment: *** — facet (zygapophyseal) joint-mediated chronic axial *** pain with prior
positive medial branch blocks at *** (and/or a prior response to RFA), now refractory.

Medical necessity under Medicare's reasonable-and-necessary standard (no NCD or LCD binds):
less-invasive options have been tried and have failed — conservative care, positive
diagnostic medial branch blocks, and radiofrequency ablation where applicable: *** . My
rationale for endoscopic medial branch transection over repeat RFA is: *** .

Plan: Endoscopic medial branch nerve transection at *** (CPT 64772). Risks, benefits, and
alternatives discussed; consent obtained.

---
.ENDONERVEMCARE  [PERIPHERAL NERVE] — swap the assessment and necessity sentences:
Assessment: *** — intractable neuropathic pain / painful neuroma of the *** nerve, refractory
to medical and interventional management. Transection is undertaken as a last resort after
failed *** options.

Where this payor diverges from the Medicare baseline

  • last-resort framing
  • no NCD/LCD basis
  • MBT leans on facet diagnostic logic

Cautions

  • R&N, MAC-adjudicated (claims reviewed); 64772 MUE = 6 units (eff 2026-01-01), MAC adoption varies. Regenerate if `medicare-in-ky-endoscopic-nerve-transection.md` `version` advances.

Prior-auth pathway

  • required: no
  • verified: no
  • note: Not on the OPD prior-auth list; uncommon/invasive -> claims frequently reviewed; submit full medical-necessity documentation.
