What 93320 covers

Code 93320 represents a complete spectral Doppler assessment performed as an add-on to an echocardiographic study. Doppler data record blood-flow velocities and direction, supporting evaluation of valve stenosis or regurgitation, intracardiac shunting, and cardiac hemodynamics. Cardiac sonographers typically acquire the data in hospitals, imaging departments, and cardiology offices; a qualified physician interprets the findings with the associated echocardiogram.

Report 93320 only with an eligible primary echo code when a complete spectral Doppler assessment is performed; it is not a stand-alone service. Documentation should support the complete Doppler assessment and link it to the corresponding echo report. Do not add it to a complete TTE code that already includes spectral Doppler, such as 93306. CMS treats 93320 as an add-on paid within the primary procedure's global period. Modifier 26 identifies the interpretation, and TC identifies the equipment and staff; billing without a modifier represents 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.

93320 billing questions

Can 93320 be billed by itself?

No. It is an add-on and must be reported with an eligible primary echocardiography procedure.

How is 93320 different from 93321?

93320 represents a complete spectral Doppler assessment. Use 93321 when the spectral Doppler assessment is limited or follow-up rather than complete.

Can 93320 be reported with 93306?

No. Code 93306 includes spectral Doppler as part of the complete transthoracic study, so 93320 would duplicate that component.

When are modifiers 26 and TC appropriate?

Use modifier 26 for the physician's interpretation and report, or TC for the technical service, including equipment and staff. Without either modifier, the claim represents the global service.

Can 93320 and 93325 be reported together?

They represent different Doppler techniques: spectral Doppler and color-flow mapping. Both may be reported when both services are performed and supported by the associated echocardiogram.

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.
