What 93306 covers
A sonographer obtains chest-wall images of the cardiac chambers, valves, pericardium, and proximal great vessels, using spectral Doppler and color flow mapping to assess blood flow and valve function. A cardiologist or other qualified physician interprets the images and reports findings such as chamber size, wall motion, ejection fraction, and valve function. Common reasons for the study include heart failure, a new murmur, atrial fibrillation, suspected valve disease, or syncope with suspected structural heart disease. The examination may take place in a cardiology office, hospital echo lab, or at the bedside.
Report 93306 once for a complete study with spectral and color Doppler; do not add separate codes for those Doppler services. Documentation should support a complete examination, identify structures that could not be adequately visualized, and include an interpretation. Modifier TC identifies the equipment and staff portion, while modifier 26 identifies the physician interpretation; billing without either modifier represents the global service. In a hospital, the interpreting physician typically bills with modifier 26. CMS applies a cardiovascular diagnostic multiple-procedure reduction to the technical component when eligible tests are furnished to the same patient on the same date.
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.

93306 billing questions
Can 93320 and 93325 be billed with 93306?
No. Spectral Doppler and color flow mapping are included in 93306. Those services may be separately reported with other eligible echocardiography codes when performed.
When should 93307 be used instead of 93306?
Use 93307 for a complete transthoracic study performed without Doppler. Use 93306 when the complete examination includes both spectral and color Doppler.
What modifier does the interpreting cardiologist use for a hospital study?
The physician appends modifier 26 to bill only the interpretation of a study performed using hospital equipment and staff. The hospital bills its technical services under its own payment system.
What if poor acoustic windows prevent some views from being obtained?
A complete study can still be reported when the required examination was attempted and the report explains which structures could not be adequately visualized. An examination intentionally restricted to selected structures or a focused question is reported with 93308.
Is strain imaging separately reportable with a complete TTE?
Yes. When speckle-tracking myocardial strain imaging is performed and documented, report add-on code 93356 with 93306, such as during chemotherapy-related cardiac monitoring.
Does 93306 apply to an examination of congenital cardiac anomalies?
Use the congenital transthoracic codes 93303 or 93304 when the examination evaluates congenital cardiac anomalies. Report applicable Doppler codes separately when those services 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.
