Office procedures, testing, drugs and surgery
Urology practices combine office visits with in-office endoscopy, diagnostic testing, drug administration, imaging and surgery in hospitals and surgery centers. Each line of work has its own coding logic and its own denial patterns, and many practices also run in-house labs, imaging or radiation services that add more rules.
Cystoscopy and endoscopic procedures
Diagnostic cystourethroscopy (52000) is the base of a large family of endoscopic codes — biopsy, fulguration, stent insertion and removal, stone treatment. When a therapeutic procedure is performed, the diagnostic cystoscopy is included in it. Most office cystoscopies have a 0-day global period, so a same-day E/M is billable only when it addresses a significant, separate problem (modifier 25) — not the evaluation that led to the scope.
Urodynamics and testing components
| Test | Codes | Watch for |
|---|---|---|
| Cystometrogram (simple or complex; with voiding pressure, urethral pressure profile or both) | 51725–51729 | One code that describes everything performed |
| Uroflowmetry and sphincter EMG | 51736, 51741, 51784 | Reported separately only when performed and documented |
| Intra-abdominal voiding pressure | 51797 (add-on) | Reported only with its primary code |
| Post-void residual by ultrasound | 51798 | Documented result and reason |
When the practice performs a test on equipment owned by a hospital, or interprets a test performed elsewhere, only the professional component (modifier 26) is billed.
Prostate services
- PSA: a screening PSA for Medicare is billed with G0103 and screening diagnoses and is limited to once a year; a PSA to monitor known disease or symptoms is a diagnostic test (84153).
- Prostate biopsy (55700) is billed with any imaging guidance as a separate service where the payer allows, and pathology is billed by the pathologist or lab.
- Drug therapy: injectable hormonal therapies and intravesical treatments are billed by HCPCS code and units, with the administration code; for single-dose containers Medicare requires modifier JW for discarded drug or JZ when none was discarded.
Surgery and global periods
Stone procedures, prostate procedures and open or laparoscopic surgery carry 10- or 90-day global periods. Visits during the global period for the same condition are not billed separately, while unrelated problems (modifier 24), planned staged procedures (58) and returns to the operating room for complications (78) are reported with the correct modifiers. Procedures performed in an ambulatory surgery center are billed by both the surgeon and the facility under different rules.
