2025 CPT code 78483

Cardiac blood pool imaging (planar), first-pass technique; multiple studies (rest and stress), wall motion study, ejection fraction, with or without quantification.

Follow the official CPT coding guidelines and payer-specific coding policies. Modifier 26 (professional component) may be appended if only the physician’s interpretation is reported. Modifier TC (technical component) may be used in appropriate settings. Adherence to local coverage determination (LCD) is also required.

Modifiers 26 (professional component) and TC (technical component) may be applied as appropriate.Other modifiers may be used according to established guidelines and payer requirements.Check local coverage determination (LCD) for specific modifier rules.

Medical necessity is determined based on the clinical indication for the study.Common indications include evaluation of chest pain, assessment of left ventricular function in patients with heart failure or valvular heart disease, and risk stratification of patients with known or suspected coronary artery disease.

A physician specializing in nuclear cardiology or a qualified radiologist performs the procedure. Responsibilities include patient preparation, tracer injection, image acquisition, and interpretation of results.In some settings, technologists may assist with image acquisition.

IMPORTANT:May be reported with stress testing codes (93015-93018).Do not report with 78451-78454.Related codes include 78472, 78473, 78481, 78494, and 78496, depending on the specifics of the imaging performed.

In simple words: This test uses special imaging to see how well your heart pumps blood while at rest and during exercise or after medicine to increase heart rate. It shows how well your heart muscle is moving and how much blood it pumps with each beat.

This CPT code encompasses cardiac blood pool imaging using the planar first-pass technique.The procedure involves multiple studies, both at rest and under stress (either exercise or pharmacologically induced).The imaging assesses left ventricular wall motion and ejection fraction, with optional quantitative analysis.The first-pass technique captures the initial passage of the radioactive tracer through the heart and lungs.

Example 1: A 65-year-old male presents with chest pain and suspected coronary artery disease.A cardiac blood pool study (78483) is performed at rest and with dobutamine stress to evaluate left ventricular function and detect any perfusion defects., A 70-year-old female with a history of heart failure undergoes a cardiac blood pool study (78483) at rest and with exercise stress to assess the ejection fraction and wall motion abnormalities., A 50-year-old male with suspected cardiomyopathy undergoes a cardiac blood pool study (78483) at rest and with pharmacologic stress to determine the extent of myocardial damage and assess cardiac function.

Complete patient history, including symptoms, risk factors, and medications.Details of the stress test (exercise or pharmacologic agent used), including the achieved heart rate and blood pressure.Images of rest and stress studies.Quantitative analysis results (ejection fraction, wall motion scores).Physician interpretation report.
