CPT® Code 72100 is used to report a radiologic examination (X-ray) of the lumbosacral spine consisting of 2 or 3 views. This imaging study is commonly performed to evaluate the lumbar vertebrae, sacrum, alignment, and surrounding structures for injury, degenerative changes, or other spinal abnormalities.
This code represents the radiographic examination itself, including image acquisition and interpretation when performed by the same provider.
Key Facts About CPT® 72100

Documentation Requirements
To support CPT 72100 billing, documentation should include:
- Patient identifiers and date of service
- Clinical indication for imaging
- Number of radiographic views obtained (2 or 3)
- Anatomical area imaged (lumbosacral spine)
- Radiologic findings and interpretation
- Final imaging report
- Ordering provider information
Complete documentation supports medical necessity and accurate radiology billing.
Reimbursement and Coding Considerations
- CPT 72100 applies specifically to 2- or 3-view lumbosacral spine radiographs
- Diagnosis coding should support the medical necessity for spinal imaging
- Different CPT codes apply when additional views or different spinal regions are imaged
- Professional and technical components may be billed separately when appropriate using modifiers (e.g., 26 and TC)
- Coverage and reimbursement vary by payer and clinical indication
Always verify payer-specific radiology billing requirements and documentation guidelines.
