Summary & Overview
CPT 93315: Transesophageal Echocardiography (TEE), 2D, Multiple/Rotating Transducers
CPT code 93315 denotes transesophageal echocardiography (TEE) using multiple transducers or a rotating transducer to capture two-dimensional cardiac images, including probe placement, image acquisition, interpretation, and reporting. As a specialized diagnostic imaging service, this code is central to the evaluation of structural heart disease, intraoperative monitoring, endocarditis assessment, and certain procedural guidance. Nationally, accurate coding for TEE influences clinical documentation, hospital and ambulatory imaging workflows, and payer reimbursement for advanced cardiac imaging.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines how payers typically classify and adjudicate TEE claims, common billing modifiers that may be applied, and where 93315 sits relative to other echocardiography codes.
Readers will learn the clinical context for using CPT code 93315, typical sites of service where the procedure is performed, and practical guidance on documentation elements expected by payers. The report also summarizes available benchmark topics and policy considerations relevant to advanced echocardiographic imaging. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 93315 describes a transesophageal echocardiography (TEE) procedure performed with multiple transducers or a rotating transducer to obtain two-dimensional (2D) imaging for visualization of the heart. The procedure includes probe placement, acquisition of diagnostic 2D images, interpretation by the provider, and a formal report of the findings.
Service type: Diagnostic cardiac imaging — transesophageal echocardiography (TEE)
Typical site of service: Hospital-based imaging suites, cardiac catheterization laboratories, and ambulatory surgical centers where advanced echocardiography is performed
Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old hospitalized adult with new-onset atrial fibrillation and suspected left atrial thrombus after a transthoracic study was inconclusive. The cardiology team requests a transesophageal echocardiography to visualize posterior cardiac structures, evaluate valvular pathology, and assess for endocarditis or thrombus prior to cardioversion. The clinical workflow includes pre-procedure evaluation (consent, NPO status, review of anticoagulation), sedation and topical anesthesia by the procedural team, placement of the TEE probe with multiple or rotating transducers, acquisition of 2D images and Doppler as indicated, real-time interpretation by the performing physician, and documentation of findings and an operative report. The procedure typically occurs in an echocardiography lab, cardiac catheterization suite, or operating room with monitoring and recovery capability for sedation.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the physician’s interpretation/report separate from technical services |
TC | Technical component | Use when billing only the equipment, probe, and sonographer services |
