What 76937 covers

This service covers ultrasound assessment and real-time guidance during vascular access. The clinician evaluates potential access sites, documents the selected vessel’s patency, watches the needle enter the vessel, and permanently records the images. It is commonly performed during central venous catheter or PICC placement and may also accompany arterial access. Physicians and other qualified practitioners perform it in hospitals, outpatient departments, and office settings.

Report 76937 only with a primary procedure for vascular access; it is an add-on code and is paid within that procedure’s global period. Documentation should support the site evaluation, vessel patency, real-time visualization of needle entry, and permanent image recording. CMS treats the service as a diagnostic test with professional and technical components: report modifier 26 for the interpretation or TC for the equipment and staff, or bill without a modifier for the global service.

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.

76937 billing questions

What documentation supports 76937?

The record should show evaluation of potential access sites, patency of the selected vessel, real-time visualization of needle entry, and permanent image recording.

Can 76937 be billed by itself?

No. It is an add-on code and must be reported with a primary vascular access procedure.

Which modifiers apply to 76937?

Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.

Is 76937 the same as ultrasound guidance for a biopsy?

No. 76937 is for vascular access, including documented vessel assessment and real-time needle entry. Code 76942 relates to ultrasound guidance for needle placement in procedures such as biopsy.

Can 76937 be reported with PICC placement?

It may be reported as an add-on with a qualifying PICC placement procedure when the required ultrasound assessment, real-time guidance, and image documentation are performed.

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.
