About 46045: Perirectal abscess drainage under anesthesia
Reports operative drainage of a perirectal abscess under anesthesia when the collection requires surgical access beyond superficial bedside drainage.
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.

46045 billing questions
How is this distinguished from 46040?
Use 46045 for documented perirectal abscess drainage under anesthesia. Select 46040 when the documented drainage service and abscess type fit that code instead.
When is 46050 a better fit?
46050 describes drainage of a superficial perianal abscess. This code is for perirectal abscess drainage under anesthesia, not a superficial perianal collection.
Should 46060 be reported when a fistula is treated?
46060 describes abscess drainage performed with fistulectomy or fistulotomy. Review the operative report to determine whether that fistula procedure was performed rather than reporting drainage alone.
What documentation supports this code?
Document the perirectal location, the abscess drainage performed, and that the service was carried out under anesthesia. The operative report should distinguish the collection from a superficial perianal abscess.
Can modifier 50 or an assistant-at-surgery claim be used?
Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for this service.
How does the global period affect postoperative billing?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When other procedures are performed in the same session, Medicare applies the standard multiple-procedure reduction.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
