Transesophageal Echocardiography (TEE) involves placing an ultrasound probe down the esophagus. It is billed using CPT 93312, but only if the same physician does both the placement and the reading.

Component Billing for TEE

  • 93312: Global code (Probe placement, image acquisition, and interpretation).
  • 93313: Probe placement ONLY (e.g., performed by an anesthesiologist).
  • 93314: Image acquisition, interpretation, and report ONLY (e.g., performed by a cardiologist reading the images while another physician places the probe).

Medical Necessity

TEE is often used during cardiac surgery or to rule out endocarditis/thrombus before cardioversion. Document the medical necessity clearly if a transthoracic echo (TTE) was deemed insufficient.

Verify Medical Necessity

Don't risk a denial. See if your ICD-10 code is on the approved Medicare LCD list.

NCCI Edits

Do not bill conscious sedation (99152) if the TEE is performed by an anesthesiologist who is already billing for anesthesia during a concurrent cardiac surgery.
