Summary & Overview
CPT 93350: Stress Echocardiography, Transthoracic with Interpretation
CPT code 93350 is a widely utilized billing code for stress echocardiography, a diagnostic procedure that evaluates cardiac function under physical or pharmacological stress. This code is essential in cardiology for identifying and monitoring heart disease, including conditions such as valve disorders, heart failure, and myocardial infarction. The procedure is typically performed in office settings or diagnostic testing facilities, making it accessible for outpatient care.
Major national payers covering this service include Aetna, Blue Cross Blue Shield, Cigna Health, Medicare, and UnitedHealthcare. Understanding coverage policies and billing requirements for these payers is crucial for providers and healthcare organizations to ensure accurate reimbursement and compliance.
This publication provides a comprehensive overview of CPT code 93350, including clinical context, payer coverage, and related coding information. Readers will gain insights into benchmarks, policy updates, and the role of stress echocardiography in cardiovascular care. The summary also highlights associated modifiers, relevant ICD-10 diagnoses, and related CPT codes, offering a clear reference for billing and clinical documentation. The information is designed to support healthcare professionals, administrators, and policy analysts in navigating the complexities of cardiovascular billing and coding.
CPT Code Overview
CPT code 93350 represents a cardiovascular procedure known as stress echocardiography. This service involves a transthoracic echocardiogram performed in real-time with image documentation (2D), including M-mode recording when indicated. The procedure is conducted during rest and a cardiovascular stress test, which may utilize treadmill, bicycle exercise, or pharmacologically induced stress. The test is interpreted and reported by a physician. Typical sites of service for this procedure include the office (POS 11) and diagnostic testing facilities. Stress echocardiography is a key diagnostic tool in cardiology, used to assess cardiac function and detect abnormalities under stress conditions.
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult presenting to a cardiology office or diagnostic testing facility with symptoms such as chest pain, shortness of breath, or suspected heart failure. The patient may have a history of rheumatic heart disease, myocardial infarction, or left ventricular dysfunction. The cardiologist orders a stress echocardiography procedure (93350) to assess cardiac function and detect ischemia or valvular abnormalities. The test is performed using treadmill or bicycle exercise, or pharmacological stress if the patient cannot exercise. Real-time transthoracic echocardiography images are obtained during rest and stress, and the interpreting physician provides a report.
