About 45000: Transrectal drainage of pelvic abscess
Reports operative drainage of a pelvic abscess approached through the rectum, when the abscess location and route match this procedure.
CPT 45000 represents surgical drainage of an abscess located in the pelvis using a transrectal approach. A colorectal or general surgeon may perform it in an operating room when the pelvic collection is reached through the rectum. The key distinction is the pelvic location of the abscess, rather than a collection confined to the rectal wall or perirectal tissues.
Select the code based on the documented abscess location and operative route. The note should identify the pelvic collection and describe drainage through the rectum. Medicare assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. In a same-session multiple-procedure case, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

45000 billing questions
How is 45000 distinguished from drainage of a rectal abscess?
Use 45000 when the abscess is pelvic and the operative route is transrectal. A collection confined to the rectum or perirectal tissues points to a different drainage code.
What documentation supports reporting 45000?
Document the pelvic abscess and the transrectal route used to drain it. The operative report should make clear that the target was pelvic, not a rectal or perirectal abscess.
Does the 90-day global period include postoperative care?
Yes. The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
Can modifier 50 be reported for bilateral drainage?
No. Modifier 50 is inappropriate for this code; report the service for the pelvic drainage rather than as a bilateral procedure.
How does Medicare handle other procedures performed in the same session?
The highest-valued procedure is paid in full, and other procedures performed in that session are paid at 50%. Medicare does not pay an assistant at surgery for 45000.
Can co-surgeons or a surgical team be reported?
No. Medicare does not permit co-surgeons or team surgery for this service.
