Official Description

Magnetic resonance (eg, proton) imaging, spinal canal and contents, without contrast material, followed by contrast material(s) and further sequences; lumbar

Common Language Description

Magnetic resonance imaging (MRI) is a sophisticated imaging technique utilized to visualize the spinal canal and its contents, specifically in the lumbar region. This procedure is noninvasive and does not involve exposure to ionizing radiation, making it a safer alternative for patients requiring detailed imaging of the spine. MRI leverages the magnetic properties of hydrogen nuclei, which are abundant in the human body, particularly in water and fat. When a patient is placed within the strong magnetic field of the MRI scanner, the hydrogen atoms align with the magnetic field. Subsequently, radiowaves are transmitted, causing these aligned protons to emit radiofrequency signals. These signals are captured by the MRI machine and processed by a computer to generate high-resolution, three-dimensional images of the spinal structures. The MRI procedure for the lumbar spine typically involves two phases: an initial scan without the use of contrast material, followed by a second scan after the administration of contrast agents. This dual-phase approach enhances the visualization of the spinal anatomy and any pathological conditions present. The resulting images provide critical information that assists healthcare providers in diagnosing various spinal disorders, including abnormal spinal alignment, vertebral body diseases or injuries, intervertebral disc issues such as herniation or degeneration, and nerve root compression. MRI of the lumbar spine is often indicated when conservative treatments for back pain have failed, or when there is a need to assess changes post-surgery. This imaging modality is essential for guiding further treatment decisions and ensuring optimal patient care.

1. Indications

Magnetic resonance imaging (MRI) of the lumbar spine is indicated for a variety of clinical scenarios, particularly when conservative management of back pain has proven ineffective. The following conditions may warrant the use of this imaging technique:

  • Back Pain Persistent back pain that does not respond to conservative treatment measures.
  • Post-Surgical Evaluation Assessment of the lumbar spine following surgical interventions to monitor for complications or changes.
  • Disc Disorders Evaluation of intervertebral disc herniation, degeneration, or dehydration.
  • Spinal Alignment Issues Investigation of abnormal spinal alignment that may contribute to symptoms.
  • Nerve Compression Identification of pinched or inflamed nerves that may be causing pain or neurological deficits.
  • Spinal Canal Assessment Measurement of the spinal canal size to ensure adequate space for the spinal cord and nerve roots.

2. Procedure

The MRI procedure for the lumbar spine is conducted in a systematic manner to ensure comprehensive imaging of the spinal canal and its contents. The following steps outline the process:

  • Patient Preparation The patient is positioned on a motorized table that slides into the MRI scanner. It is essential for the patient to remain still during the imaging process to obtain clear images.
  • Initial Imaging Without Contrast The first phase of the MRI involves capturing images of the lumbar spine without the use of contrast material. This initial scan provides baseline images of the spinal structures.
  • Administration of Contrast Material After the initial imaging, contrast material is administered to enhance the visibility of certain structures within the spinal canal. This may involve intravenous injection of a gadolinium-based contrast agent.
  • Further Imaging Sequences Following the administration of contrast, additional imaging sequences are performed. These sequences are designed to highlight areas of interest and provide detailed views of the spinal anatomy.
  • Image Processing The signals emitted from the protons in the body are processed by the MRI machine's computer, which converts the data into high-resolution, three-dimensional images of the lumbar spine.
  • Image Review Finally, the physician reviews the images to assess for any abnormalities or conditions that correlate with the patient's symptoms.

3. Post-Procedure

After the MRI procedure, patients may resume their normal activities unless otherwise instructed by their healthcare provider. There are typically no specific post-procedure care requirements, as MRI is a noninvasive procedure. However, patients should be monitored for any immediate reactions to the contrast material, if used. The physician will review the images and discuss the findings with the patient, which may lead to further diagnostic or therapeutic interventions based on the results of the MRI.

This is a primary code that can be used with these additional add-on codes.

0649T Add-on Code MPFS Status: Carrier Priced APC S Quantitative magnetic resonance for analysis of tissue composition (eg, fat, iron, water content), including multiparametric data acquisition, data preparation and transmission, interpretation and report, obtained with diagnostic MRI examination of the same anatomy (eg, organ, gland, tissue, target structure); single organ (List separately in addition to code for primary procedure)
0698T Add-on Code Resequenced Code MPFS Status: Carrier Priced APC S ASC Z2 Quantitative magnetic resonance for analysis of tissue composition (eg, fat, iron, water content), including multiparametric data acquisition, data preparation and transmission, interpretation and report, obtained with diagnostic MRI examination of the same anatomy (eg, organ, gland, tissue, target structure); multiple organs (List separately in addition to code for primary procedure)
26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
