Clinical Context
A 52-year-old patient presents to the outpatient radiology department with progressive neck pain, intermittent paresthesia in both upper extremities, and intermittent gait instability after a fall six weeks prior. The referring neurosurgeon requests detailed evaluation of the cervical spinal canal for suspected disc herniation, spinal cord compression, and possible intradural pathology. The patient arrives fasting not required, is screened for MRI safety and contrast allergies, and completes a pregnancy check if applicable. The MRI technologist acquires a standard cervical spine MRI protocol first without intravenous gadolinium contrast to evaluate alignment, intervertebral discs, foramina, and spinal cord signal. After review of the non-contrast sequences and confirmation that contrast is indicated, the radiologist orders intravenous gadolinium and repeat contrast-enhanced sequences to assess for enhancement of the spinal cord, nerve roots, leptomeninges, or an enhancing mass.
The typical workflow includes scheduling and insurance verification, MRI safety screening, IV placement by technologist or nurse, non-contrast MRI acquisition, radiologist review and decision to proceed with contrast, contrast administration and post-contrast imaging, radiologist interpretation, and issuance of a signed report to the referring provider. Typical sites of service are outpatient hospital radiology departments, freestanding imaging centers, and inpatient hospital radiology when the patient is admitted. The service type is diagnostic imaging (MRI cervical spine with and without contrast).
Coding Specifications
| Modifier | Description | When to Use |
|---|
26 | Professional component | When billing only the interpreting physician’s portion separate from technical facility charges |
TC | Technical component | When billing only the facility/technical portion for scanner, technologist, and supplies |
50 | Bilateral procedure | Not typically applicable to spine MRI; use only when payer requires explicit bilateral indicator for paired organ imaging |
59 | Distinct procedural service | When another distinct procedure or service not normally reported together was performed unrelated to the MRI study |
76 | Repeat procedure by same physician | When the MRI study (or portion) is repeated later the same day by the same provider |
77 | Repeat procedure by another physician | When another physician repeats the imaging study the same day |
52 | Reduced services | When the imaging procedure is partially reduced or not fully performed |
53 | Discontinued procedure | When the MRI was started but discontinued due to patient intolerance or safety concern |
25 | Significant, separately identifiable E/M service | When a separately billable evaluation and management visit is performed on the same day as imaging |
76 | Repeat procedure by same physician | Duplicate entry intentionally avoided; see above |
| Taxonomy Code | Specialty | Notes |
|---|
| 246Z00000X | Diagnostic Radiology | Most common interpreting specialty for MRI spine studies |
| 2084P0800X | Neurological Surgery | Neurosurgeons frequently order and review MRI cervical spine studies for operative planning |
| 207RC0000X | Orthopaedic Surgery | Orthopedic spine specialists commonly evaluate MRI results for nonoperative and operative management |
| 208800000X | Physical Medicine & Rehabilitation | PM&R physicians use MRI findings in planning conservative spine care |
| 2084N0400X | Neuroradiology | Specialist radiologists may interpret complex spinal cord and intradural pathology |

Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|
72052 | Magnetic resonance (e.g., proton) imaging, spinal canal and contents, thoracic; without contrast material | Performed when thoracic spine evaluation is needed in addition to cervical imaging; may be ordered in a combined spine MRI study |
72157 | Magnetic resonance imaging, cervical spinal canal and contents, without contrast material, followed by contrast material and further sequences of the cervical spine (repeat of 72156 descriptor) | An adjacent or alternative code sometimes used depending on payer descriptors; confirms similar service if coding conventions differ |
72141 | Radiologic examination, spine, cervical; 2 or 3 views (plain radiographs) | Plain radiographs often performed before MRI for initial alignment assessment or preoperative planning |
70450 | CT head or brain, without contrast (single volume) | Ordered when concurrent evaluation of head is needed for trauma or neurologic symptoms alongside cervical MRI |
76000 | Fluoroscopic guidance for vascular access (e.g., for difficult IV placement) | Used rarely if advanced vascular access or special guidance is required to administer contrast for MRI |
If additional or site-specific codes are required in a payer’s policy, coders should reference local guidelines. Use 72156 for MRI of the cervical spine performed both without and with contrast when documenting and billing the combined study.
