CPT code 93317: Congenital TEE, imaging and report2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 93317 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 93317 covers

This code represents the imaging, interpretation, and reporting portion of a transesophageal echocardiographic study focused on congenital cardiac anomalies. A cardiologist or other qualified physician interprets the ultrasound images and documents findings; the images are acquired using an ultrasound probe positioned in the esophagus. It is distinct from the complete congenital TEE service, which includes probe placement, and from a code limited to probe placement.

Medicare assigns this CPT code physician fee schedule status C, meaning the Medicare Administrative Contractor prices each claim rather than CMS publishing a national payment amount. The study has professional and technical components: modifier 26 identifies interpretation, while modifier TC identifies the equipment and staff portion; without either modifier, the code represents the global service. The code describes diagnostic imaging, not intraoperative TEE monitoring.
