CPT code 11771 represents the surgical excision of a pilonidal cyst or sinus when the procedure requires extensive dissection into deeper subcutaneous tissues. As a distinct procedural code, it captures more complex pilonidal disease management than superficial excision codes and is used to document resource use, clinical complexity, and care setting. Nationally, accurate use of CPT code 11771 matters for clinical reporting, reimbursement classification, and quality measurement in ambulatory and hospital outpatient surgical care.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the procedure, expected sites of service, and typical billing considerations. The publication outlines benchmark metrics and payer coverage patterns where available, highlights relevant policy or coding guidance that affects claim adjudication, and summarizes clinical scenarios that commonly justify use of CPT code 11771 versus less extensive excision codes.

This briefing is intended for health system revenue cycle teams, surgical practices, and policy analysts seeking a clear national-level summary of CPT code 11771, including clinical scope, payer relevance, and areas to review in coding and coverage policies. Data not available in the input will be noted where applicable.
