Summary & Overview
CPT 78300: Bone Scan (Limited Area) Scintigraphy
CPT code 78300 represents a limited-area bone scan (scintigraphy), a nuclear medicine imaging procedure in which a radionuclide is injected and targeted images are acquired to evaluate a single bone or joint. This procedure is important for diagnosing focal bone disease, evaluating pain or suspected localized injury, and guiding clinical management when a full-body scan is not required. Nationally, bone scintigraphy remains a key diagnostic tool in musculoskeletal and oncologic care pathways, influencing imaging utilization and care coordination across outpatient imaging centers and hospital radiology departments.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical indications and service context, typical sites of service, common modifier usage noted in billing practice, and the payer landscape relevant to reimbursement and prior authorization norms. The publication summarizes benchmarks where available, highlights policy considerations that affect utilization of limited-area bone scans, and provides clinical context to help administrative and clinical stakeholders understand when CPT code 78300 is used versus other nuclear medicine imaging codes. Data not available in the input is identified explicitly where applicable.
Billing Code Overview
CPT code 78300 is a bone scan (scintigraphy), limited area nuclear medicine procedure. The provider injects a radionuclide prior to imaging to examine bones in a limited area of the body, such as a single bone or joint, to evaluate bone pathology or injury.
Service Type: Nuclear medicine imaging — limited/targeted bone scintigraphy
Typical Site of Service: Hospital outpatient imaging department, freestanding imaging center, or outpatient radiology/nuclear medicine clinic
Clinical & Coding Specifications
Clinical Context
A 68-year-old ambulatory male with a history of prostate cancer presents with new onset localized bone pain in the pelvis. The oncology team requests a targeted nuclear medicine bone scan of the pelvis to evaluate for metastatic disease. The patient arrives to an outpatient radiology suite. The nuclear medicine technologist obtains IV access and injects a radionuclide tracer (commonly Tc-99m-labeled diphosphonate). After an appropriate uptake period, the nuclear medicine physician performs scintigraphic imaging of the limited pelvic region, acquiring planar and/or single-photon emission computed tomography (SPECT) images as indicated. The physician interprets images, documents findings in the report, and provides face-to-face consultation if necessary. Results are routed to the referring oncologist for management decisions.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the physician interpretation for the bone scan when the technical component is billed separately. |
TC | Technical component | Use when billing only the technical component (equipment, radiopharmaceutical, technologist) and the professional interpretation is billed separately. |
