Summary & Overview
CPT 78453: Cardiac Planar Perfusion Study, 2D
CPT code 78453 represents a single planar nuclear medicine study of the heart performed to identify areas of deficient blood flow using two-dimensional imaging. This cardiac perfusion imaging code is used to localize regions of reduced myocardial blood supply and supports diagnostic decision-making for ischemia and other perfusion abnormalities. Nationally, accurate coding for cardiac nuclear studies impacts coverage decisions, utilization monitoring, and care pathways for patients with suspected coronary ischemia.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a clinical and billing-focused overview of the code, typical sites of service, common billing modifiers, and how CPT code 78453 fits into cardiac imaging service lines. The publication also outlines relevant benchmarks and policy considerations where available, and summarizes practical coding context for clinicians, billing staff, and policy analysts.
This report is written for a national audience and concentrates on clinical purpose, typical delivery settings, and payer relationships relevant to cardiac nuclear perfusion imaging using a single planar 2D approach. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 78453 describes a single planar nuclear medicine study of the heart performed to identify areas of deficient myocardial blood flow. The procedure produces two-dimensional (2D) planar images to localize regions with reduced perfusion.
Service Type: Cardiac nuclear medicine perfusion imaging (single planar study)
Typical Site of Service: Hospital outpatient imaging department, outpatient nuclear medicine center, or ambulatory imaging facility
Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old male with exertional chest pain and known coronary artery disease referred by cardiology for a myocardial perfusion planar imaging study to evaluate areas of deficient blood flow to the myocardium. The patient presents to a hospital nuclear medicine department or an outpatient imaging center. After initial intake and review of indications and medications, an IV radiotracer (commonly technetium-labeled agent) is administered. Rest and/or stress imaging protocols are performed with single planar (2D) images acquired to localize perfusion defects. Images are interpreted by a nuclear cardiologist or cardiologist with nuclear medicine competency, and a report documents areas of reduced perfusion, comparison to prior studies if available, and correlation with clinical presentation. Typical site of service is an outpatient imaging center or hospital outpatient department; inpatient performance can occur for hospitalized cardiac patients. The clinical workflow includes pre-test screening, tracer injection, appropriate timing for image acquisition, acquisition of planar 2D images, image processing, physician interpretation, and generation of the final report for the referring provider.
