What 50400 covers
A urologist uses this code for a simple open pyeloplasty, reconstructing the renal pelvis or ureteropelvic junction (UPJ), with or without an incision into the renal pelvis. A typical clinical indication is UPJ obstruction causing impaired drainage or hydronephrosis. The service is performed in an operating room; laparoscopic pyeloplasty is represented by a different code. The operative report should establish the repair performed and support selection of the simple rather than complicated pyeloplasty code.
Report 50400 for the simple repair, not the complicated repair represented by 50405. The major-surgery global period 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% reduction. For bilateral reporting with modifier 50, CMS pays 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
