CPT code 52000: Cystoscopy, diagnostic examination only2026 Medicare rate & RVUs in California

Medicare pays $228.81–$288.57 for 52000 in the office in California, from Chico, CA to San Benito County, CA. Which amount applies depends on the service address.

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

What 52000 covers

The clinician passes a flexible or rigid cystoscope through the urethra to inspect the urethral lining, bladder neck, bladder walls, and ureteral orifices. Urologists perform the examination most often, sometimes in an office using topical anesthetic gel and a flexible scope. It may also be performed in a hospital or ambulatory surgery center. Common reasons include hematuria, bladder cancer surveillance, recurrent urinary tract infections, voiding symptoms, and suspected urethral stricture.

Report 52000 for a diagnostic examination when a more extensive cystourethroscopy does not include it during the same session. A biopsy, ureteral catheterization, or clot evacuation performed through the scope calls for the applicable procedure code instead. Document the indication, structures examined, and findings. Its 0-day global period includes routine same-day preoperative and postoperative care; a significant, separately identifiable E/M service may be reported with modifier 25. When other procedures are separately reportable in the same session, the standard multiple-procedure rule pays the highest-valued procedure in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted. Office practice expense is higher than facility practice expense.
