Summary & Overview
CPT 78102: Limited-Area Bone Imaging After Radiotracer Administration
CPT code 78102 represents a limited-area nuclear medicine bone imaging study performed after intravenous administration of a radiopharmaceutical. This focused diagnostic procedure captures bone marrow or bone tissue radiotracer uptake in a localized anatomical region, supporting evaluation of focal pathology such as localized infection, fracture, or focal metabolic activity. Nationally, bone scintigraphy remains an important noninvasive tool in musculoskeletal and oncologic imaging because it can detect physiologic changes before structural changes appear on radiography.
Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for using a limited-area bone scan, customary settings where the service is provided (outpatient imaging centers and hospital nuclear medicine departments), and what typical reporting and coding considerations accompany a focal bone scintigraphy service. The publication outlines benchmarks and common billing practices where available, and summarizes policy or coverage themes affecting nuclear medicine bone imaging nationally. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 78102 describes a limited area bone imaging procedure performed after intravenous administration of a radiopharmaceutical (radiotracer). The study images bone tissue where the tracer localizes and is used to visualize distribution and uptake within a restricted anatomical region rather than a whole-body or multiple-region exam.
Service type: Diagnostic nuclear medicine bone imaging, limited area
Typical site of service: Outpatient imaging center or hospital radiology/nuclear medicine department

Clinical & Coding Specifications
Clinical Context
A 68-year-old outpatient with a history of prostate cancer presents with new onset localized bone pain of the right hip. The referring oncologist requests focused bone imaging to evaluate for suspected metastatic involvement limited to the pelvic region. The nuclear medicine team schedules a limited-area bone scan after intravenous administration of a technetium-labeled radiopharmaceutical. The patient arrives to an outpatient imaging center or hospital nuclear medicine department; an IV is placed, the tracer is injected, and after appropriate uptake time the technologist and interpreting physician acquire planar and/or limited-field SPECT images of the targeted pelvic bones. The interpreting nuclear medicine physician documents findings, compares with prior imaging if available, and issues a report to the referring provider. Billing is submitted using 78102 for bone marrow (bone) imaging of a limited area, with the professional and technical components split as appropriate and modifiers appended per payer rules (for example, professional component 26 when reporting only interpretation).
