72141

Magnetic resonance (eg, proton) imaging, spinal canal and contents, cervical; without contrast material

Magnetic Resonance Imaging (MRI) of the cervical spine without contrast material (CPT code 72141) is a highly sensitive, non-invasive advanced diagnostic imaging modality utilized to evaluate the anatomical structures of the cervical spinal canal and its contents. This includes the cervical vertebrae (C1 through C7), intervertebral discs, spinal cord, nerve roots, surrounding paraspinal musculature, and associated ligamentous structures. The procedure leverages a powerful magnetic field, radiofrequency pulses, and advanced computerized processing to generate high-resolution, multiplanar images (sagittal, axial, and coronal) of the cervical spine. It is frequently indicated for patients presenting with persistent neck pain, cervical radiculopathy, myelopathy, sensory or motor deficits in the upper extremities, trauma, suspected disc herniation, degenerative disc disease, and spinal stenosis. The without contrast designation specifies that gadolinium-based contrast agents are not administered intravenously during this study. In a typical clinical workflow, the patient is positioned supine on the MRI table with their head and neck resting within a specialized cervical or neurovascular receiver coil. This coil operates to capture the radiofrequency signals emitted by the hydrogen protons in the patient's body as they realign with the main magnetic field following radiofrequency excitation. Various pulse sequences (such as T1-weighted, T2-weighted, Short Tau Inversion Recovery [STIR], and Gradient Echo [GRE]) are meticulously acquired to differentiate between fat, water, bone marrow, and neural tissues. T1-weighted images provide excellent anatomical detail, while T2-weighted images are optimal for identifying pathology such as edema, fluid accumulations, and spinal cord lesions. The radiologist reviews the resulting digital images on a high-definition Picture Archiving and Communication System (PACS) workstation, carefully analyzing the spinal alignment, vertebral body integrity, disc height and hydration, neural foraminal patency, and the presence of any compressive elements on the thecal sac or exiting nerve roots. A comprehensive report is then generated and transmitted to the referring physician to guide subsequent medical or surgical management. The high tissue contrast resolution makes this procedure the gold standard for evaluating soft tissue pathologies within the cervical spine without exposing the patient to ionizing radiation. Furthermore, careful clinical documentation must support the medical necessity of this procedure, specifically noting the duration of symptoms and the failure of any conservative management strategies when the condition is non-emergent.

Clinical Indications

  • Chronic or acute neck pain (cervicalgia) refractory to conservative treatment
  • Cervical radiculopathy with radiating arm pain, numbness, or tingling
  • Suspected cervical disc herniation or degenerative disc disease
  • Cervical spinal stenosis causing neurogenic claudication or myelopathy
  • Evaluation of cervical spine trauma or suspected occult fractures
  • Congenital anomalies of the cervical spine
  • Follow-up of previously diagnosed conservative non-surgical cervical spine conditions

Procedure Steps

  1. The patient is screened for MRI contraindications including pacemakers, cochlear implants, and other ferromagnetic foreign bodies.
  2. The patient is positioned supine on the MRI examination table.
  3. A dedicated cervical spine radiofrequency (RF) receiver coil is positioned around the patient's neck to optimize signal-to-noise ratio.
  4. The patient is advanced into the isocenter of the MRI scanner bore.
  5. A localizer (scout) scan is performed to ensure accurate anatomical alignment and positioning.
  6. Multiple pulse sequences are acquired, typically including sagittal and axial T1-weighted, T2-weighted, and STIR (Short Tau Inversion Recovery) images.
  7. The technologist monitors the acquisition in real-time to check for motion artifacts and image quality.
  8. Once all imaging sequences are completed successfully, the patient is removed from the scanner.
  9. The acquired images are sent to the Picture Archiving and Communication System (PACS) for interpretation.
  10. A radiologist reviews the images, evaluates the cervical spine anatomy and pathology, and generates a formal diagnostic report.

Coding Guidelines

  • Report 72141 for an MRI of the cervical spine performed entirely without intravenous contrast.
  • Do not report 72141 in conjunction with 72142 (MRI cervical spine with contrast) or 72156 (MRI cervical spine without and with contrast) for the same patient on the same day.
  • If the patient cannot tolerate the study (e.g., due to severe claustrophobia) and the study is aborted, apply modifier 52 (Reduced Services) or 53 (Discontinued Procedure) depending on payer policy and facility versus professional fee billing.
  • Ensure medical necessity is documented, often requiring a minimum period of conservative management for non-traumatic neck pain prior to imaging.
  • For professional component only, append modifier 26. For technical component only, append modifier TC. If billing globally, no modifier is needed.
