Urologic surgery
About 50400: Simple open pyeloplasty
Reports open reconstruction of the renal pelvis or ureteropelvic junction for a simple repair, commonly to relieve an obstruction impairing kidney drainage.
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.

50400 billing questions
How do I choose between 50400 and 50405?
Use 50400 for a simple pyeloplasty and 50405 for a complicated one. The operative report should support the selected level; the diagnosis alone does not establish complexity.

No. CPT 50544 represents laparoscopic surgical pyeloplasty; 50400 is the simple open pyeloplasty code.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
How are additional procedures in the same session paid?
CMS pays the highest-valued procedure in full and applies the standard multiple-procedure reduction to the others.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How is a bilateral pyeloplasty reported?
CMS identifies this as a bilateral procedure; with modifier 50, payment is at 150%.
