What 93303 covers
This study uses an ultrasound probe on the chest to assess heart structure and function when congenital cardiac anatomy is present or suspected. A cardiologist or other qualified clinician interprets the images; the technical service is generally performed by trained cardiac sonography staff in a hospital, clinic, or imaging practice. It may be used for initial assessment or ongoing evaluation of congenital heart disease in children or adults.
Select this code for a complete transthoracic study focused on congenital cardiac abnormalities, rather than a limited follow-up examination or a standard study for acquired heart disease. The report should support the congenital indication and document a complete examination and interpretation. Bill the global service without a component modifier, or use modifier 26 for interpretation or TC for equipment and staff when those components are billed separately. CMS applies the cardiovascular diagnostic multiple procedure reduction 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.

93303 billing questions
When should this code be used instead of 93306?
Use this code for a complete transthoracic study evaluating congenital cardiac abnormalities. Code 93306 describes a complete standard transthoracic study with Doppler and is not the congenital-specific choice.
How does this differ from 93304?
This code represents a complete congenital transthoracic examination. Code 93304 is for a limited or follow-up congenital study.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
Which part is subject to the cardiovascular diagnostic multiple procedure reduction?
The technical component is subject to the reduction. CMS applies the reduction to the technical component.
What documentation supports reporting the complete study?
Document the congenital cardiac indication, the complete transthoracic examination performed, and the interpreting clinician’s findings. A limited follow-up examination should be distinguished from a complete study.
Can Doppler services be reported with this study?
Codes 93320 and 93325 describe spectral Doppler and color-flow mapping services that may accompany congenital echocardiography when performed and separately documented.
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.
