What 93312 covers
A transesophageal echocardiogram uses an ultrasound probe passed into the esophagus to obtain views of the heart and nearby structures. A cardiologist or other qualified physician may use it to evaluate valve disease, suspected endocarditis, prosthetic valves, intracardiac masses, or a possible cardiac source of embolism. The service is performed in settings such as a hospital, outpatient department, or procedure area when transthoracic views are inadequate or a closer view is needed.
Report 93312 when the service includes probe placement, image acquisition, and the physician’s interpretation and report. The record should support the indication, the examination performed, and the findings in the signed report. Modifier 26 identifies the professional interpretation and report; modifier TC identifies the equipment and staff portion. Without either modifier, the claim represents the global service. When multiple cardiovascular diagnostic procedures are performed, the multiple-procedure reduction applies to the technical component.

93312 billing questions
When should 93312 be chosen instead of a transthoracic echo?
Use 93312 for a transesophageal examination, with the ultrasound probe positioned in the esophagus. A transthoracic study such as 93306 uses images obtained through the chest wall.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the interpretation and report, while modifier TC identifies the equipment and staff portion. Billing without either modifier represents the global service.
Can 93313 or 93314 be reported with 93312?
93313 describes probe placement alone, and 93314 describes image acquisition with interpretation and report. They represent split portions of the service rather than additional portions to report alongside a complete 93312 service.
Does a multiple-procedure reduction affect 93312?
The cardiovascular diagnostic multiple-procedure reduction applies to the technical component. For a global service, the reduction affects its technical portion.
What documentation supports reporting 93312?
Document the reason for the transesophageal examination, that probe placement and image acquisition were performed, and the physician’s findings and interpretation in a report.
