By September 30, 2025: Billing team must update revenue cycle system to automatically deny claims containing CPT codes 0577U, 0579U, 0580U, 0581U, 0584U, 0589U, 0591U, 0594U, 0596U, 0598U, 0599U, 0415U; HCPCS codes C1740, C1742, C8006, Q4391; and unlisted codes 38999, 43499, 43999, 45399 when associated with lymphaticovenous bypass/anastomosis, Peroral Plication of the Esophagus, or Endoscopic full thickness resection procedures for Medicare Advantage members. Concurrently, remove CPT codes 43497, 0338T, 0339T, 0569T, 0570T from the experimental/investigational list in the billing system to allow coverage as medically necessary services. Update denial templates to reference policy MA00.005at and communicate change to providers via staff meeting and email. Failure to implement will result in incorrect denials of now-covered services (43497, 0338T, 0339T, 0569T, 0570T) and missed denials of non-covered experimental services. Verify changes are live in billing software before October 1, 2025.
