What 93981 covers

This service uses duplex ultrasound to assess blood flow in penile vessels, such as when evaluating erectile dysfunction for evidence of impaired arterial inflow or venous outflow. Urologists, radiologists, or vascular laboratory personnel may perform the study, often in an office or imaging setting. A vasoactive medication may be injected into the corpora cavernosa during diagnostic testing, with the ultrasound findings interpreted in that clinical context.

Select the limited-study code when the documented examination is focused or incomplete rather than a complete assessment of penile arterial inflow and venous outflow. The record should identify the indication, the vessels or flow findings assessed, and the reason the study was limited. Report the professional interpretation with modifier 26 and the equipment-and-staff portion with modifier TC; without a modifier, the claim represents the global service. The cardiovascular diagnostic multiple-procedure reduction applies to the technical component.

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.

93981 billing questions

How do I choose this code over 93980?

Use 93981 for a limited penile vascular examination. Use 93980 when the documented study is complete, evaluating both arterial inflow and venous outflow.

Can a diagnostic injection be reported with this study?

A diagnostic intracavernosal injection may be separately reported when it is performed and documented as a distinct service. Code 54235 describes that injection service.

How should the professional and technical portions be billed?

Use modifier 26 for the physician’s interpretation and modifier TC for the equipment and staff portion. Billing without either modifier represents the global service.

Which portion is affected by the cardiovascular diagnostic multiple-procedure reduction?

The reduction applies to the technical component. When billing the components separately, it is the TC portion to which this reduction applies.

What documentation supports reporting a limited study?

Document the clinical indication, the scope of the penile vessel assessment, and the findings obtained. The record should support that the examination was limited rather than a complete arterial inflow and venous outflow study.

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.
