Urologic surgery
About 50065: Secondary open renal stone operation
Reports a secondary open operation to remove a kidney stone when the documented surgical circumstances distinguish it from routine initial stone removal.
A urologist uses this code for a secondary open operation to remove a calculus from the kidney. The procedure involves surgically reaching the kidney and treating the stone through an open approach, typically in a hospital operating room. The code distinguishes this service from routine open stone removal and from percutaneous procedures that reach the kidney through a small access tract.
Choose the code based on the operative circumstances, not stone size alone; the record should describe the calculus, the open approach, and why the operation is secondary. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others at 50%. For bilateral surgery reported with modifier 50, payment is at 150%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.

50065 billing questions
How does this differ from 50060?
50065 is for a secondary open operation for a renal calculus. Use 50060 for routine open removal when the circumstances do not support reporting a secondary operation.
Does stone size determine whether to report 50065?
No. The selection turns on the secondary-operation circumstances, not stone size alone. A large staghorn calculus has a distinct open procedure code, 50075.
Can the kidney incision and stone extraction be billed separately?
The access to the kidney and treatment of the calculus are part of the open stone operation; do not separately report those operative steps as distinct services.
How is bilateral surgery paid?
When the procedure is performed bilaterally and reported with modifier 50, CMS pays at 150%.
What documentation supports reporting 50065?
Document the kidney and calculus treated, the open approach, and the operative circumstances supporting classification as a secondary operation. The operative report should make the distinction from routine stone removal clear.
Can an assistant surgeon be reported?
Assistant-at-surgery payment may be made for this code. Co-surgeons and team surgery are not permitted under the CMS rules provided.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
