Summary & Overview
CPT 78802: Whole-Body Nuclear Medicine Imaging with Radiotracer
CPT code 78802 represents a single–day, whole‑body nuclear medicine imaging study using a gamma–emitting radiotracer to diagnose and localize tumors, inflammatory processes, or to evaluate radiopharmaceutical distribution. The code also encompasses vascular flow and blood pool imaging of cardiac function when performed. This procedure is a key diagnostic tool in oncology, infection imaging, and select cardiac assessments, and its use affects imaging workflows, facility resource allocation, and reimbursement pathways nationally.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and common service settings, benchmarking expectations across major payers, and notes on billing considerations relevant to single–day whole‑body nuclear imaging. The publication outlines common modifiers used with the service and highlights areas where policy updates and payer-specific rules commonly influence coverage and claims processing. Clinical teams, coding specialists, and revenue managers will learn how CPT code 78802 fits into diagnostic imaging portfolios and what to expect when submitting claims for whole‑body nuclear medicine studies. Data not available in the input for specific payer rate values, associated taxonomies, and ICD‑10 diagnosis mappings are noted where applicable.
Billing Code Overview
CPT code 78802 describes a diagnostic nuclear medicine study using a gamma–emitting radiotracer to detect and localize tumors, inflammatory processes, or to assess radiopharmaceutical agent distribution. The service includes vascular flow and blood pool imaging when performed and represents single–day whole body imaging.
-
Service type: Diagnostic nuclear medicine whole-body imaging with radiotracer administration
-
Typical site of service: Outpatient imaging centers, hospital nuclear medicine departments, and ambulatory diagnostic facilities
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a history of colorectal cancer presents with rising carcinoembryonic antigen (CEA) and new bone pain. The referring oncologist orders a whole-body nuclear medicine scan using a gamma-emitting radiotracer to evaluate for metastatic disease and to localize potential tumor deposits and sites of radiopharmaceutical distribution. The patient arrives at an outpatient nuclear medicine department or hospital radiology/nuclear medicine suite. The technologist confirms identity, reviews the clinical indication and allergies, and administers the radiopharmaceutical intravenously. After an appropriate uptake period, the patient undergoes single-day whole-body planar and spot imaging, with flow and blood-pool sequences performed if cardiac function assessment is clinically indicated. The interpreting nuclear medicine physician documents findings, impression, and correlation with prior imaging, signs/symptoms, and laboratory data. The final report supports oncology treatment planning and may prompt additional targeted imaging or biopsy if suspicious focal uptake is identified.
