Urologic surgery
About 50543: Laparoscopic partial kidney removal
Reports laparoscopic removal of part of a kidney, commonly to excise a renal mass while preserving functioning kidney tissue.
A urologic surgeon uses a laparoscopic approach to remove a portion of the kidney, typically to excise a localized renal mass while retaining the remaining kidney. The operative work includes managing the kidney and the excision site as part of the partial nephrectomy. This code distinguishes kidney-preserving resection from laparoscopic ablation of a renal mass and from removal of the entire kidney.
Select the code when the operative report supports laparoscopic partial rather than complete removal or ablation. Documentation should identify the kidney treated, the laparoscopic approach, the portion removed, and the indication and findings supporting the resection. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

50543 billing questions
How is this different from laparoscopic renal mass ablation?
Report 50543 when the surgeon removes part of the kidney. Code 50542 describes laparoscopic ablation of a renal mass rather than partial nephrectomy.
When should the surgeon report radical nephrectomy instead?
Use 50545 when the laparoscopic operation removes the kidney radically rather than preserving the remaining kidney after partial excision.
Does the 90-day global period include related postoperative care?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is bilateral surgery reported?
The CMS rule specifies modifier 50 for a bilateral procedure, with payment at 150%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
What documentation supports 50543 rather than a complete nephrectomy?
The operative report should establish the laparoscopic approach and that only a portion of the kidney was removed, including the treated side and operative findings.
