Urologic surgery
About 50290: Perinephric cyst excision
Report this surgery when a surgeon excises a cyst in the tissue surrounding the kidney, rather than a cyst arising from the kidney itself.
A surgeon, commonly a urologist, removes a cyst located in the perinephric tissue around the kidney. The procedure treats the cyst itself; it is distinct from removing a cyst arising within renal tissue and from removing the kidney. The operative record should make the cyst’s location clear and describe its excision. This service is performed in an operative setting.
Report the code for excision of the perinephric cyst, with documentation supporting the site and the work performed. The service has a 90-day global period, which includes 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. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation. Team surgery is not permitted, and modifier 50 is inappropriate.
