I work at a dermatology office and we recently had an audit with BCBS. They are doing a special investigation on codes 17000 & 17110. They are requesting us to send in clinic note along with claim form if the patient received these services. . I am now receiving feedback on it and they are denying these codes for medical necessity. I reviewed the physician’s notes and the patients are being treated for AKs (L57.0) with 17000 and ISKs (L82.0) or Warts with 17110. This is being stated in the notes as well as the location(s) of the lesions. I am not sure what BCBS will need to process these particular codes for reimbursement. Does anyone have any suggestions?
