Cardiac imaging

About 93321: Limited Doppler echocardiography

Reports limited or follow-up spectral Doppler assessment performed with echocardiographic imaging, such as focused evaluation of blood flow or pressure gradients.

This add-on covers a limited or follow-up spectral Doppler assessment during an echocardiographic examination, using pulsed-wave and/or continuous-wave Doppler to evaluate blood-flow patterns or velocities. It may help assess a focused hemodynamic question, such as a valve gradient, rather than provide the broader Doppler assessment of a complete study. A cardiac sonographer typically acquires the images, and a qualified physician interprets the findings in an outpatient imaging setting or hospital.

Report 93321 only with an eligible primary echocardiographic procedure; a limited transthoracic study such as 93308 is a common pairing. The record should support the focused Doppler service and its medical purpose. CMS treats it as an add-on paid within the primary procedure’s global period. Modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff, and reporting without either modifier represents the global service.

93321 billing questions

When should 93321 be selected instead of 93320?

Use 93321 for limited or follow-up Doppler assessment. Use 93320 when the Doppler assessment is complete.

Can 93321 be billed by itself?

No. It is an add-on and must be reported with an eligible primary echocardiographic procedure, such as a limited study reported with 93308.

Does a complete study reported with 93306 also need 93321?

93306 includes spectral Doppler as part of the complete transthoracic study. Do not add 93321 merely to report that included Doppler work.

How do modifiers 26 and TC apply?

Use modifier 26 for the physician’s interpretation or TC for the technical service. Without either modifier, the claim represents the global service.

What documentation supports limited Doppler reporting?

Document the focused or follow-up Doppler assessment, its clinical purpose, and the findings interpreted. The record should distinguish this work from a complete Doppler examination.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
