CPT code 93316: TEE probe placement, congenital cardiac anomalies2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 93316 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 93316 covers

This code represents the clinician’s work to advance and position a transesophageal echocardiography probe for evaluation of congenital cardiac anatomy. It is used when probe placement is performed as a distinct service, often in a procedural or operating-room setting, while image acquisition and the interpretation and report are handled separately. The service concerns positioning the probe, not the diagnostic findings from the resulting study.

Report it only when documentation supports probe placement for a congenital cardiac evaluation and identifies the clinician who performed that work. When one clinician performs the complete congenital TEE service, including placement, imaging, interpretation, and reporting, the complete-service code 93315 is the better fit. If another clinician performs the imaging and interpretation/report, code 93317 describes that separate portion. CMS fee-schedule payment for 93316 reflects the probe-placement service.
