What 51785 covers

This study records electrical activity from the anal or urethral sphincter using a needle electrode. Urologists and other clinicians performing urodynamic or pelvic-floor evaluations may use it when investigating suspected sphincter dysfunction, neurogenic bladder, or urinary incontinence. The needle technique distinguishes this service from sphincter EMG performed without a needle electrode.

Report the study when the needle-electrode sphincter EMG is performed and documented; the record should identify the site studied and support that the EMG service was completed. It may be performed as part of a broader urodynamic evaluation, with other services reported when separately performed and documented. Medicare recognizes professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and no component modifier represents the global service. For multiple procedures in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

51785 billing questions

How does 51785 differ from 51784?

51785 is the needle-electrode sphincter EMG. Use 51784 for sphincter EMG performed without a needle electrode.

Can 51785 be reported with a cystometrogram?

It may be reported with a cystometrogram when the sphincter EMG is separately performed and documented as part of the evaluation. The services are distinct: 51785 evaluates sphincter electrical activity, while cystometrogram codes assess bladder pressure and function.

When should modifier 26 or TC be used?

Use modifier 26 for the professional interpretation and modifier TC for the technical service, including equipment and staff. Without either modifier, the claim represents the global service.

How does Medicare pay when 51785 is performed with other procedures?

For multiple procedures performed in the same session, Medicare pays the highest-valued procedure in full and applies a 50% reduction to the others.

What documentation supports 51785?

Document the sphincter site examined, use of a needle electrode, and the EMG service performed. The record should distinguish this study from any separately reported urodynamic tests.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
