Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 46288 covers

A colorectal surgeon repairs the fistula by mobilizing a flap of tissue to cover its internal opening. This approach may be selected for a tract whose anatomy or relationship to the anal sphincter makes laying it open undesirable. The operation is generally performed in an operating room, with the operative report identifying the tract, internal opening, flap tissue, and closure technique.

Report 46288 when the documented repair uses an advancement flap, not simply because an anal fistula is present. The 90-day global period includes the day-before preoperative visit and related postoperative care during the following 90 days. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
