Summary & Overview
CPT 78454: Multiple Planar Myocardial Perfusion Study
CPT code 78454 denotes a cardiac nuclear imaging procedure consisting of multiple planar myocardial perfusion studies to identify areas of deficient blood flow. This imaging modality is used to detect myocardial ischemia and guide clinical decision making for patients with suspected or known coronary artery disease. Nationally, myocardial perfusion imaging remains a widely used noninvasive test for evaluating perfusion abnormalities and informing diagnostic and treatment pathways.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise synthesis of what 78454 represents clinically, typical sites where the service is delivered, and the payer landscape affecting coverage and claims processing. The publication summarizes common modifiers and administrative considerations encountered with this service line and highlights typical billing contexts.
This report is intended to give clinicians, coding staff, and policy analysts a clear, national-level overview of CPT code 78454, its clinical role in cardiac imaging, and the administrative dimensions relevant to reimbursement and documentation. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 78454 describes a nuclear cardiology procedure in which the provider performs multiple planar studies of the heart to determine areas of deficient blood flow. The primary clinical purpose is to identify regions of myocardial ischemia or reduced perfusion.
Service type: Cardiac nuclear imaging / myocardial perfusion planar study
Typical site of service: Hospital outpatient imaging department or ambulatory imaging center

Clinical & Coding Specifications
Clinical Context
A 64-year-old male with a history of hypertension and hyperlipidemia presents with exertional chest pain and dyspnea. His cardiologist orders a myocardial perfusion study to evaluate for areas of ischemia and to guide revascularization decisions. The patient arrives to a hospital outpatient nuclear medicine unit where technologists initiate intravenous access, confirm allergies and recent medications, and review recent cardiac testing. The procedure performed is a multiple planar myocardial perfusion study (78454) using radiotracer injection at rest and during pharmacologic stress (e.g., regadenoson) because the patient cannot perform adequate exercise.
During the session, a nuclear medicine physician or cardiologist supervises radiotracer administration, monitors hemodynamics and ECG changes, interprets raw tomographic images, and documents findings of fixed or reversible perfusion defects. Images are reconstructed and processed with gated acquisition to assess left ventricular function. The final report includes perfusion defect localization, severity, and ejection fraction; results inform decisions for coronary angiography, percutaneous coronary intervention, or medical management. Typical site of service is a hospital outpatient imaging center, ambulatory imaging center, or inpatient nuclear medicine department. The service type is nuclear medicine myocardial perfusion imaging (multiple planar studies).
