Summary & Overview
CPT 46280: Complex Anorectal Fistula Surgery, Possible Seton Placement
CPT code 46280 represents surgical management of multiple or complex anorectal fistulas in high anal locations (suprasphincteric, high transsphincteric, extrasphincteric) or multiple fistulas with tracts adjacent to the anorectal ring. It is used to report operative procedures that may include seton placement and addresses anatomically challenging fistula disease that carries higher clinical complexity and potential morbidity. Nationally, this code matters because it captures resource-intensive operative care provided by colorectal and general surgeons and is relevant for surgical quality measurement and reimbursement for complex anorectal disease.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coding intent and clinical context, expected sites of service, and common billing modifiers associated with complex anorectal fistula procedures. The publication also provides benchmarking context and policy-relevant considerations about coverage and documentation expectations for complex fistula surgery, along with clinical context to help clinicians and billing professionals align operative reports with appropriate code selection.
This summary is written for a national audience and focuses on the code’s clinical meaning, typical care settings, and the payer landscape relevant to complex anorectal fistula surgery.
Billing Code Overview
CPT code 46280 describes surgical treatment of multiple or complex anorectal fistulas located in high anal areas — including suprasphincteric, high transsphincteric, or extrasphincteric regions — or multiple fistulas with tracts near the anorectal ring. The procedure may include placement of a seton as part of management.
-
Service type: Complex anorectal fistula surgery, including fistulotomy/fistulectomy with possible seton placement
-
Typical site of service: Operating room or ambulatory surgical center, frequently performed by colorectal surgeons or general surgeons with expertise in anorectal procedures
Clinical & Coding Specifications
Clinical Context
A 42-year-old male with a history of recurrent perianal sepsis presents with persistent drainage and intermittent severe perianal pain. Examination and pelvic MRI identify multiple complex fistulous tracts in the high anal region, including a suprasphincteric tract and a high transsphincteric tract with internal openings near the anorectal ring. The colorectal surgeon schedules a definitive operative procedure under general anesthesia: exploration, fistula tract excision and curettage, possible placement of a seton for drainage, and repair as appropriate. Preoperative workflow includes history and focused exam, review of MRI, informed consent, anesthesia evaluation, perioperative antibiotics, and postoperative wound-care instructions with planned follow-up for seton management and assessment of sphincter function.

26 | Professional component | When reporting only the surgeon’s professional service separate from a facility technical component (rare for this procedure). |
51 | Multiple procedures | When multiple CPT procedures (distinct surgical services) are performed during the same operative session. |
