72148

Lumbar Spine MRI Without Contrast

Code Description

CPT code 72148 is used to report magnetic resonance imaging (MRI) of the lumbar spine performed without contrast material. The examination produces detailed images of the spinal canal, vertebrae, intervertebral discs, spinal cord, and surrounding soft tissues to help diagnose conditions affecting the lower back.

This study is commonly ordered to evaluate chronic lower back pain, suspected disc herniation, spinal stenosis, nerve compression, and other degenerative or traumatic conditions of the lumbar spine. Because no contrast agent is administered, CPT 72148 is appropriate only for non-contrast MRI examinations.

When to Use 72148

Common examples include:

  • chronic lower back pain

  • lumbar disc herniation

  • sciatica

  • spinal stenosis

  • nerve root compression

  • degenerative disc disease

  • preoperative spine evaluation

Documentation Requirements

Documentation should include:

  • reason for the examination

  • lumbar spine evaluated

  • confirmation that no contrast was administered

  • physician or radiologist interpretation

  • diagnostic findings

  • medical necessity for the MRI

Common Billing Mistakes

Common billing mistakes include:

  • reporting CPT 72148 when contrast material was used

  • failing to document that the study was performed without contrast

What conditions can a lumbar spine MRI diagnose?

A lumbar MRI may help diagnose herniated discs, spinal stenosis, nerve compression, degenerative disc disease, tumors, infections, and other lower back conditions.
