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

What 46045 covers

A surgeon, commonly a colorectal or general surgeon, opens and drains a perirectal abscess in an operative setting with anesthesia. The service is used for a collection requiring operative access rather than drainage of a superficial perianal abscess. The operative note should identify the abscess location and document the drainage performed.

Select this code when the documented service is perirectal abscess drainage under anesthesia; use the abscess site and the procedure performed to distinguish it from nearby drainage codes. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, Medicare pays the highest-valued procedure in full and other procedures at 50%. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.
