CPT code 52317: Bladder stone removal, small or simple calculus2026 Medicare rate & RVUs

Medicare pays $868.42 for 52317 nationally in the office and $304.28 in a hospital or facility. Local office rates run $767.01–$1,154.02.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 52317 covers

A urologist uses a cystoscope and appropriate instruments to break up a bladder calculus and remove the fragments through the urinary outlet. This service addresses stones within the bladder, such as a calculus found during evaluation of urinary symptoms or identified on imaging; it is not the ureteral-stone procedure. The operative record should describe the stone’s location, size and complexity, the method used to fragment it, and removal of the resulting material.

Select this code for a small or straightforward bladder stone procedure; the larger or more complex bladder-stone service is a separate sibling code. The service includes fragmentation and removal, rather than separate reporting for each fragment. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy-family pricing applies. Modifier 50 is inappropriate for this bladder procedure. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
