What 50593 covers

The physician places one or more cryotherapy probes through the skin into a renal tumor and uses freeze-thaw cycles to destroy the target. Imaging guides probe placement and treatment monitoring as part of the procedure. Urologists and interventional radiologists commonly perform this treatment in a hospital or ambulatory surgery setting for patients with a renal mass selected for percutaneous ablation. A biopsy performed as part of the ablation is included in the service.

Report the code for the percutaneous cryotherapy approach, not for laparoscopic ablation or surgical removal of renal tissue. The operative report should support the treated kidney, tumor target, percutaneous access, cryotherapy, and imaging-guided treatment. The procedure has a 10-day global period, which includes related postoperative visits during that period. For bilateral treatment, modifier 50 is paid at 150%. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
