Urology CPT Codes
Urology mixes office diagnostics with endoscopic and open procedures, most of them in the Surgery section's Urinary and Male Genital subsections. Cystoscopy is the specialty's bread and butter, urodynamics comes with its own bundling maze, and prostate procedures pair with imaging guidance and pathology that bill separately. Global periods here run from zero days to 90, so the calendar matters as much as the code.

Urology CPT codes
Cystourethroscopy, Diagnostic
Diagnostic scope of the bladder and urethra. Bundles into any therapeutic cysto code from the same session.
Prostate Biopsy, Needle or Punch
Transrectal or transperineal prostate biopsy. Guidance and pathology bill separately.
Vasectomy
Vasectomy including postoperative semen analysis. Coverage varies significantly by plan.
Post-Void Residual, Ultrasound
Bladder scan measuring residual urine. Frequency-limited by most payers.
Cystoureteroscopy with Laser Lithotripsy and Stent
Ureteroscopy with laser stone fragmentation and stent placement in one code.
Complex Cystometrogram with Voiding Pressure
Urodynamic study of bladder filling and voiding pressures. Includes the simple CMG.

Urology billing notes
Diagnostic cystoscopy (52000) carries no global period, but the therapeutic cysto codes bundle the diagnostic look. Scope in, treat something, and 52000 disappears into the therapeutic code.
Urodynamics codes stack when distinct tests are performed and documented, but payers bundle aggressively. The complex cystometrogram (51728) already includes the simple version.
55700 (prostate biopsy) covers the needle work. Ultrasound guidance (76942) and the pathology on each specimen bill separately, which is why one biopsy visit produces three different claim lines.
51798, the ultrasound post-void residual, is a quick office code with strict frequency limits at most payers. Once per visit, and medical necessity still applies.
Vasectomy (55250) is often a benefit exception: some plans cover it fully, others exclude it. Verify benefits before the procedure, because the patient owns the bill if the plan excludes it.
Frequently asked questions about urology billing
Can I bill 52000 with a stone removal or other therapeutic cysto?▼
No. The diagnostic cystoscopy is bundled into every therapeutic cystoscopy code from the same session. Bill the therapeutic code alone; 52000 only stands when the scope was purely diagnostic.
What bills alongside a prostate biopsy?▼
Typically three things: 55700 for the biopsy itself, 76942 for ultrasound guidance when used and documented with saved images, and surgical pathology for the specimens. Each has its own requirements, and the guidance code is the one most often missed.
How often can a post-void residual be billed?▼
Generally once per encounter, and payers set frequency limits across encounters too. It needs a reason in the note, like retention symptoms or medication monitoring. Routine scanning of every patient at every visit is a pattern payers flag quickly.
