What 93975 covers

This study uses ultrasound and Doppler to assess blood flow into and out of abdominal, pelvic, scrotal, or retroperitoneal structures. It may be performed for suspected renal vascular disease, portal or hepatic flow concerns, mesenteric vascular disease, or scrotal vascular conditions. A sonographer typically acquires the images, and a qualified physician interprets the study. The examination must support a complete assessment of the relevant arterial inflow and venous outflow, rather than a limited evaluation.

Report 93975 for the complete study; use the documented anatomy, vessels examined, Doppler findings, and interpretation to support that level rather than a limited study. Bill globally without a component modifier when one claim includes both the professional interpretation and technical service. Modifier 26 identifies the professional interpretation, while modifier TC identifies equipment and staff. When multiple cardiovascular diagnostic procedures are performed, the multiple procedure reduction applies to the technical component.

How to choose

93976Vascular study
93976 is for a limited examination of the relevant organ-related vessels; 93975 is for the complete arterial inflow and venous outflow study.
93978Vascular duplex
93978 evaluates the aorta, inferior vena cava, or iliac vasculature as its target. Choose 93975 for the complete vascular evaluation of abdominal, pelvic, scrotal, or retroperitoneal structures.
93979Vascular duplex
93979 is the limited aortoiliac study. It differs from 93975 both in the vascular territory examined and in the extent of the study.

93975 billing questions

How does 93975 differ from 93976?

93975 represents a complete evaluation of arterial inflow and venous outflow for the relevant abdominal, pelvic, scrotal, or retroperitoneal structures. Use 93976 when the documented examination is limited.

When should modifier 26 or TC be reported?

Use modifier 26 for the physician's professional interpretation and modifier TC for the technical service, including equipment and staff. Report without either modifier when billing the global service.

What documentation supports the complete study?

Document the structures and vessels examined, the arterial inflow and venous outflow assessment, Doppler findings, and the interpreting provider's conclusions. The record should show why the examination was complete rather than limited.

Does the multiple procedure reduction affect the interpretation?

The CMS cardiovascular diagnostic multiple procedure reduction applies to the technical component. It is relevant to the TC portion when multiple cardiovascular diagnostic procedures are performed.

Is 93975 the right code for an aortoiliac duplex?

Select the code based on the anatomy and vessels studied. A study directed at the aorta, inferior vena cava, or iliac vasculature is distinguished from 93975's evaluation of organ-related arterial inflow and venous outflow.

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.
