Urologic surgery
About 50542: Laparoscopic renal mass ablation
Reports laparoscopic destruction of one or more renal masses, such as a tumor treated with cryoablation or radiofrequency ablation.
A urologic surgeon uses laparoscopic access to destroy a renal mass while preserving the kidney when the treatment plan calls for ablation rather than excision. Common techniques include cryoablation and radiofrequency ablation. The procedure is generally performed in an operating room, and intraoperative ultrasound guidance is included when used. This code is for a renal mass, not a renal cyst or a tumor removed by partial nephrectomy.
Report the service when the operative documentation identifies the renal mass, laparoscopic approach, ablation performed, and treated side or sides. The code covers ablation of one or more masses in the procedure. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

50542 billing questions
How does this differ from laparoscopic partial nephrectomy?
Use 50542 when the renal mass is destroyed in place. Use 50543 when the surgeon removes the mass with a portion of kidney.
Can this code be used for a renal cyst?
No. Laparoscopic ablation of a renal cyst is reported with 50541; 50542 is for a renal mass.
Is intraoperative ultrasound separately reported?
The code includes intraoperative ultrasound guidance when performed. Do not separately report that guidance as though it were outside the ablation service.
How is bilateral ablation reported?
For a bilateral procedure, report modifier 50; CMS pays the service at 150%.
What happens when another procedure is performed in the same session?
CMS pays the highest-valued procedure in full and applies the standard multiple-procedure reduction to the other procedure or procedures. The 90-day global period includes related postoperative care.
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.
