CPT code 78832 represents a single-day SPECT study performed with concurrent CT imaging to localize tumors, inflammatory processes, or radioactive tracer distribution across multiple anatomic sites or separate acquisitions. This hybrid nuclear medicine service can include vascular flow and blood pool imaging when performed and is used when imaging at least two areas or conducting distinct acquisitions on the same day. Nationally, the code is significant because it captures combined functional and anatomic imaging that supports diagnostic localization and treatment planning across oncology, infection/inflammation assessment, and certain pulmonary evaluations.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the code, typical sites of service, and what the code denotes in terms of study scope. The publication provides benchmarks and policy-relevant information where available, clarifies service definitions for billing and coding clarity, and outlines common operational considerations for facilities that perform multi-site SPECT/CT imaging. Data not available in the input is noted where applicable.
