CPT code 52330: Stone manipulation, without stone removal2026 Medicare rate & RVUs

Medicare pays $590.19 for 52330 nationally in the office and $231.13 in a hospital or facility. Local office rates run $522.93–$777.96.

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

What 52330 covers

A urologist passes a cystoscope through the urethra into the bladder and manipulates a ureteral calculus without extracting it. A classic use is moving a ureteral stone back toward the kidney before planned extracorporeal shock-wave treatment; this service is the endoscopic manipulation, not the later fragmentation or removal. It is most often performed in an operating room or ambulatory surgery center, though office services also occur.

Report 52330 when the operative note supports cystoscopic manipulation of a ureteral stone and no stone extraction. Document the stone’s location, the manipulation performed, and whether treatment was unilateral or bilateral. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral procedures, modifier 50 is paid at 150%. When related endoscopies are performed together, CMS applies endoscopy-family pricing. CMS does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.
