What 93307 covers
This service uses an ultrasound transducer on the chest to create cardiac images for a comprehensive assessment of heart structure and function. A sonographer typically acquires the images in a hospital or outpatient imaging setting, and a physician, often a cardiologist, interprets them. The study includes two-dimensional imaging and M-mode recording when performed, without Doppler evaluation. Findings may address chamber size, wall motion, valves, and the pericardium.
Report 93307 for a complete study, not a focused or follow-up examination; the report should support the scope of a complete evaluation. When the complete study includes Doppler, 93306 is the relevant code instead. The service may be billed globally, or divided between the interpretation with modifier 26 and the equipment-and-staff portion with modifier TC. When multiple cardiovascular diagnostic procedures are performed, CMS applies its multiple-procedure reduction to the technical component.

93307 billing questions
How does 93307 differ from 93306?
93307 describes a complete transthoracic study without Doppler. Use 93306 when the complete study includes Doppler evaluation.
Can 93307 be used for a limited or follow-up echo?
No. 93307 is for a complete examination; 93308 is the related code for a limited or follow-up transthoracic study.
Can the professional and technical portions be billed separately?
Yes. Report modifier 26 for the physician interpretation and modifier TC for the technical portion; an unmodified claim represents the global service.
What documentation supports a complete study?
The record should show a comprehensive transthoracic examination and its findings, rather than a focused assessment of a single question or structure.
How does the multiple-procedure reduction affect 93307?
When multiple cardiovascular diagnostic procedures are performed, CMS applies the reduction to the technical component of 93307.

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.
