Which code would be used to indicate an echocardiogram?

The code used to indicate an echocardiogram is 93306. This code specifically refers to a transthoracic echocardiography, which is a non-invasive imaging technique that uses ultrasound to create images of the heart. It captures important information about the structure and function of the heart, aiding in the diagnosis and management of various cardiovascular conditions.

The other codes listed pertain to different procedures or services. For example, 99223 is a code for a comprehensive hospital visit, 93454 refers to a coronary angiography procedure, and 99024 indicates a postoperative follow-up visit that does not include additional services or procedures. Therefore, 93306 is the correct choice because it uniquely identifies a specific echocardiographic procedure.
