What 93313 covers
This code represents placing a transesophageal echocardiography probe, without the image acquisition, interpretation, or report. It is commonly relevant in an operating room when a clinician places the probe for intraoperative TEE and a different clinician performs and reports the imaging service. The probe passes through the esophagus to provide access for cardiac ultrasound views; placement alone is the work represented here, not ongoing image interpretation or monitoring.
Choose 93313 when the documented service is limited to probe placement. The record should identify the clinician who placed the probe and support that this service was separate from the TEE imaging and interpretation. When one clinician performs and reports the complete TEE service, 93312 includes probe placement. When the imaging service is separately reported, 93314 describes image acquisition, interpretation, and reporting without probe placement. Code 93318 instead describes intraoperative TEE monitoring, rather than placement alone.

93313 billing questions
How does 93313 differ from 93312?
93313 covers probe placement alone. Code 93312 covers a complete TEE service that includes probe placement, image acquisition, interpretation, and reporting.
Can 93313 be reported with 93314?
Yes, when probe placement and the separately reported image acquisition, interpretation, and report are performed as distinct services. The documentation should support each clinician's work.
Does 93313 include interpretation of the TEE images?
No. Image acquisition, interpretation, and reporting without probe placement are represented by 93314.
What documentation supports 93313?
Document the probe placement, the clinician who performed it, and how the service was separate from the TEE imaging and interpretation. A complete TEE report alone does not establish a separately performed placement service.
When is 93318 a better fit?
Use 93318 for intraoperative TEE monitoring with ongoing image acquisition and interpretation. Code 93313 represents probe placement alone.
