CPT 78830: SPECT with Concurrent CT, Single-Area Single-Day
Headline: CPT code 78830 defines single-area SPECT with concurrent CT for localized tumor, inflammatory, or tracer imaging
Lead: CPT code 78830 represents a nuclear medicine SPECT study performed with concurrent CT during a single-day, single-area acquisition to localize tumors, inflammatory processes, or radioactive tracer distribution; vascular flow and blood pool imaging are included when performed. This imaging code is clinically important for targeted localization that informs diagnostic and therapeutic decision-making.
Why it matters nationally: Single-area SPECT/CT studies are widely used across hospital outpatient departments and freestanding imaging centers to refine anatomic localization and functional assessment. CPT code 78830 captures a distinct service type that combines functional nuclear imaging with CT correlation in a single session, supporting care pathways in oncology, infection/inflammation evaluation, and targeted radionuclide procedures.
Key payers covered: Analysis typically includes major national payers such as Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
What readers will learn: Readers will get a concise overview of the clinical context and service setting for CPT code 78830, which payers commonly cover this service, and the typical procedural scope (single-area, single-day SPECT with concurrent CT). The publication also outlines common modifiers and coding considerations where available. Data not available in the input is explicitly noted where applicable.

Billing Code Overview
CPT code 78830 describes a single-day single-area SPECT (single photon emission computed tomography) with concurrent CT used to localize a tumor, inflammatory process, or radioactive tracer distribution. The procedure may include vascular flow and blood pool imaging if those components are performed as part of the same single-day acquisition.
Service Type: Nuclear medicine SPECT with concurrent CT imaging, single area, single-day acquisition.
Typical Site of Service: Hospital outpatient imaging center, freestanding imaging center, or nuclear medicine department, with most studies performed on the head, neck, chest, pelvis, or another single anatomic area.
