Introduction
Nuclear medicine imaging and PET scans are advanced diagnostic tools that provide functional imaging of organs and tissues. Proper CPT coding ensures correct reimbursement and prevents denials due to bundling issues or incorrect modifier use. This guide covers key CPT codes for nuclear medicine and PET scans, along with billing guidelines, modifier use, and a final reference table with CPT descriptions and RVUs.
Understanding Nuclear Medicine & PET Scan Coding
- Nuclear medicine uses radiopharmaceuticals to assess organ function, including cardiac stress tests and bone scans.
- Positron Emission Tomography (PET) scans are commonly used for cancer staging, brain imaging, and cardiac evaluation.
CPT Codes for Nuclear Medicine & PET Scans
Cardiac Nuclear Medicine CPT Codes
- 78452 – Myocardial perfusion imaging, multiple studies, rest and stress.
- 78491 – Myocardial imaging, single study at rest.
- 78492 – Myocardial imaging, multiple studies at rest and stress.
Bone & Organ Scans
- 78306 – Bone scan, whole body.
- 78315 – Bone scan, three-phase study.
- 78707 – Kidney scan, complete.
- 78803 – Radiopharmaceutical localization of inflammatory process, whole body.
PET Scan CPT Codes
- 78811 – PET scan, limited area (e.g., brain, heart).
- 78812 – PET scan, whole-body, limited area.
- 78813 – PET scan, whole-body, with or without CT.
- 78816 – PET scan, tumor imaging.
SPECT Scan CPT Codes
- 78830 – SPECT scan, limited area.
- 78831 – SPECT scan, whole body.
- 78832 – SPECT scan with CT imaging.
Billing Guidelines & Modifier Usage
-
Common Modifiers:
- -26 – Professional component (physician’s interpretation).
- -TC – Technical component (use of imaging equipment and technician).
- -52 – Reduced service if the complete imaging study was not performed.
-
Bundling Considerations:
- PET scans (78811–78816) should not be billed separately from CT scans if performed together.
- Nuclear stress tests (78452) may require documentation of clinical necessity for reimbursement.
Common Denials & How to Avoid Them
- Medical Necessity Denials: Ensure appropriate diagnosis codes justify PET scans and nuclear studies.
- Modifier Use Issues: Use -26 and -TC modifiers correctly when splitting professional and technical components.
- Duplicate Claim Rejections: Avoid resubmitting PET scans without additional medical necessity justification.

Conclusion
Accurate CPT coding for nuclear medicine and PET scan procedures is essential for maximizing reimbursement and preventing denials. Understanding bundling rules, modifier application, and payer-specific guidelines will help ensure accurate claims.
