Urologic surgery
About 50020: Open renal or perirenal abscess drainage
Open drainage of an abscess in or around the kidney, reported when the surgeon surgically exposes and drains the infected collection.
A urologist typically performs this operation in an operating room to surgically expose and drain a purulent collection within the kidney or in the tissue surrounding it. The service is defined by open operative drainage of the abscess, rather than drainage through an image-guided catheter or a procedure directed at a renal calculus. The operative report should identify the abscess location and describe the open drainage performed.
Medicare assigns 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, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

50020 billing questions
How is 50020 distinguished from renal exploration?
Report 50020 when open drainage of a renal or perirenal abscess is the operative service. Renal exploration is a different selection when exploration, rather than abscess drainage alone, defines the procedure.
Can image-guided drainage be reported as 50020?
No. 50020 describes open operative drainage; image-guided catheter drainage is a different approach and may point to a drainage code such as 49405, depending on the service performed.
What postoperative care is included?
The 90-day global includes the day-before preoperative visit and related postoperative care through 90 days after surgery.
Should modifier 50 be used for bilateral abscesses?
No. CMS identifies bilateral adjustment as inappropriate for 50020; modifier 50 should not be used.
How are assistants and co-surgeons handled?
Medicare does not pay an assistant at surgery for this code. Co-surgeons are payable only with supporting documentation, and team surgery is not permitted.
