What Blue Cross NC's policy requires for mohs surgery & dermatologic surgery — bcc, scc, melanoma in situ, slnb, pdt

How Blue Cross NC denies mohs surgery & dermatologic surgery — bcc, scc, melanoma in situ, slnb, pdt — and how to counter it

Where Blue Cross NC pushes back: 1) 'Reconstruction is cosmetic'; 2) 'Could close primarily'; 3) 'Scar revision is cosmetic'.

Counter-arguments that hold up: AAD/ACMS Position Statement on Mohs Reconstruction: flap/graft/complex closure for oncologic defect is integral surgical step. Document defect size + functional preservation rationale (eyelid: prevent ectropion/entropion; nasal valve: prevent obstruction; oral commissure: prevent microstomia + speech/eating impairment). Photographs of defect support necessity. For scar revision: document specific functional deficit (contracture, ectropion, nasal valve collapse) — not cosmetic.
