Summary
Aetna's updated Winged Scapula policy (CPB 0859) establishes medical necessity criteria for surgical muscle transfer procedures after failed conservative therapy (12 months for traumatic cases, 24 months for non-traumatic cases), while designating magnetic resonance neurography, long thoracic nerve neurolysis, and polyester tape scapulopexy as experimental/investigational and therefore non-covered. Billing teams must ensure proper code selection, apply appropriate medical necessity documentation requirements, and deny claims for experimental procedures.
Action Required
REQUIREMENTS: By January 9, 2026, billing team must: (1) Update billing system to require documentation of at least 12 months (traumatic) or 24 months (non-traumatic) conservative therapy before approving CPT 23395, 23397, or 23400 claims; (2) Implement claim denial logic for CPT 64708 and 64727 when billed for long thoracic nerve treatment—these are non-covered; (3) Deny all claims for magnetic resonance neurography (no specific CPT assigned) related to long thoracic nerve evaluation; (4) Deny all scapulopexy claims (CPT 23400) that use polyester tape technique or are submitted for cosmetic indications only; (5) Train providers to document functional impairment (not cosmetic deformity) and conservative therapy duration in medical record prior to surgical code submission; (6) Add ICD-10 code M21.80 (winged scapula—covered if criteria met) and G54.0 (long thoracic nerve—not covered for neuroplasty/neurolysis) to denial rules in system. Failure to implement these controls will result in improper reimbursement and potential compliance violations.
