Summary
Aetna updated its bunionectomy clinical policy (CPB 0629) effective December 11, 2025, establishing specific medical necessity criteria for four procedure categories: simple bunionectomy, bony correction bunionectomy, first MTP joint surgical correction, bunionette correction, cheilectomy, and arthrodesis. The policy requires 6 months of documented conservative treatment, radiographic confirmation of specific angle measurements, skeletal maturity documentation, and symptom persistence before coverage. Billing teams must verify all four eligibility criteria are met and documented before claim submission to avoid denials.
Action Required
DEADLINE: Effective December 11, 2025 - Billing and clinical teams must immediately implement the following: (1) Billing team: Update claim submission templates and billing software to flag bunionectomy claims (CPT 11055-11057, 73620) requiring documentation review before submission. (2) Providers: Ensure all bunionectomy claim submissions include: documented 6-month conservative treatment history; weight-bearing X-ray reports showing specific angle measurements (HVA 15+ degrees for simple bunionectomy, HVA 30+ degrees AND IMA 12+ degrees for bony correction); proof of skeletal maturity; and persistent pain/difficulty walking despite conservative care. (3) Front desk/coding: Create pre-claim checklist requiring verification of all four criteria are present in medical record before billing. (4) All staff: Familiarize with exclusions list—bunionectomy claims will be DENIED if patient has severe vascular insufficiency, non-ambulatory status (except for ulcer relief), cosmetic indications, or poor surgical site tissue. Claims submitted without complete medical necessity documentation will be denied by Aetna.
