Summary & Overview

CPT 72148: MRI of Lumbar Spine Without Contrast

CPT code 72148 is a widely utilized billing code for magnetic resonance imaging (MRI) of the lumbar spine without the use of contrast material. This diagnostic radiology procedure is essential for evaluating a range of spinal conditions, including low back pain, disc displacement, spinal stenosis, radiculopathy, and ligament sprains. The code is most frequently billed in outpatient hospital settings, reflecting its role in routine and urgent diagnostic workups.

Major national payers, including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare, provide coverage for this procedure, making it a cornerstone in spine imaging reimbursement and policy discussions.

CPT Code Overview

CPT code 72148 represents magnetic resonance imaging (MRI) of the lumbar spinal canal and contents without contrast material. This procedure is classified under diagnostic radiology (diagnostic imaging) procedures of the spine and pelvis. It is commonly performed in an outpatient hospital setting (Place of Service 22), where advanced imaging technology is used to evaluate the lumbar region for a variety of clinical indications. The MRI provides detailed images that assist clinicians in diagnosing conditions affecting the lower spine and its surrounding structures.

Clinical & Coding Specifications

Clinical Context

A patient presents to an outpatient hospital setting with persistent low back pain, radiculopathy, or symptoms suggestive of lumbar spinal stenosis or disc displacement. The ordering physician, often a neurologist, orthopedic surgeon, or primary care provider, requests a lumbar spine MRI without contrast to evaluate the spinal canal and its contents. The radiology department schedules the procedure, and a radiologist interprets the images to assist in diagnosis and management. This workflow is typical for diagnostic imaging of the lumbar spine in cases of suspected disc pathology, nerve impingement, or ligament injury.

Coding Specifications

Modifiers:
- 26 - Professional Component: Used when only the interpretation of the MRI is performed by the radiologist.
- TC - Technical Component: Used when only the technical aspect (equipment, technician, etc.) is billed.
- 59 - Distinct Procedural Service: Used to indicate a distinct service from other procedures performed on the same day.
- 76 - Repeat Procedure by Same Physician: Used when the same physician repeats the MRI procedure.
