MRI Cervical Spine Without Contrast CPT Code Guide

The CPT code for an MRI of the cervical spine without contrast is 72141. This code is used when a magnetic resonance imaging study of the cervical spinal canal and contents is performed without the administration of contrast material. It is the standard code for non-contrast cervical spine MRI and is widely recognized across payers, including Medicare.

Understanding the correct CPT code is essential for accurate billing and reimbursement. Using the wrong code—such as 72156 for a combined without-and-with contrast study—can lead to claim denials or audits. This guide explains the official descriptor, when to use 72141, how it differs from related codes, and the documentation and modifier requirements to ensure clean claims.

Official Descriptor and Clinical Definition of CPT 72141

The American Medical Association (AMA) defines CPT code 72141 as: Magnetic resonance (e.g., proton) imaging, spinal canal and contents, cervical; without contrast material. This code falls under the Diagnostic Radiology section for spine and pelvis procedures (72100–72295). It is a HCPCS Level I code maintained by the AMA and reimbursed under the CMS Medicare Physician Fee Schedule.

In clinical terms, 72141 covers an MRI of the cervical spine that captures soft tissue structures—intervertebral discs, spinal cord, nerve roots, and surrounding musculature—using proton-based sequences. No gadolinium or other contrast agent is injected before, during, or after the scan. The radiologist's report must clearly state that no contrast was used; otherwise, the claim may be denied or downcoded.

When to Use CPT 72141: Indications and Medical Necessity

CPT 72141 is appropriate when a physician orders a non-contrast cervical spine MRI to evaluate structural or neurological conditions. Payers require documented medical necessity, meaning the clinical indication must appear in the ordering physician's notes and correspond to a supported ICD-10-CM diagnosis code. Common indications include:

• Cervical radiculopathy: nerve root compression from disc herniation or foraminal stenosis causing arm pain, numbness, or weakness.
• Myelopathy: spinal cord compression producing gait disturbance, upper extremity weakness, or hyperreflexia.
• Disc herniation: suspected or confirmed disc prolapse at any cervical level.
• Cervical spinal stenosis: narrowing of the spinal canal or neural foramina.
• Neck pain with neurological signs: axial neck pain with radicular symptoms unresponsive to conservative treatment.
• Suspected cord pathology: evaluation of demyelinating disease, syrinx, or intramedullary lesion (non-enhancing).
• Post-surgical assessment: follow-up imaging where contrast is not clinically indicated.

Medicare and many commercial payers have local coverage determinations (LCDs) that specify which diagnosis codes meet coverage criteria. For example, CMS LCD L35175 (MRI and CT Scans of the Head and Neck) lists covered diagnoses for Medicare. Always verify the current LCD for your Medicare Administrative Contractor (MAC) jurisdiction, as covered diagnosis lists vary. Pairing the correct ICD-10 code with 72141 is foundational for avoiding medical necessity denials.

CPT 72141 vs. 72142 and 72156: Key Differences

The cervical spine MRI code family includes three primary codes based on contrast use:

CPT Code	Description	When to Use
72141	MRI cervical spine without contrast	No contrast administered
72142	MRI cervical spine with contrast	Contrast administered only (rarely used alone)
72156	MRI cervical spine without and with contrast	Both non-contrast and post-contrast sequences performed in same exam

Selecting the wrong code is the most common billing error for these studies. The contrast protocol documented in the radiologist's report determines the correct code, not the order form. If contrast was administered, you must bill 72156 (or 72142 if only post-contrast images were obtained, though this is uncommon). Never use 72141 when contrast was given.

According to the American College of Radiology (ACR) Appropriateness Criteria, MRI without contrast may be appropriate for many cervical spine conditions, including chronic neck pain and suspected disc pathology. Contrast is typically reserved for suspected infection, tumor, or certain post-surgical complications. The ordering physician selects the protocol based on clinical scenario, and the coder must verify the documented protocol before assigning the code.

Modifiers for CPT 72141: Professional, Technical, and Global Billing

Modifier selection depends on who is billing and what component of the service they provided:

• Modifier 26 (Professional Component): Used when a radiologist interprets the scan but does not own the equipment or facility. The radiologist bills 72141-26.
• Modifier TC (Technical Component): Used by the facility that owns the equipment and provides the technologist, supplies, and space. The facility bills 72141-TC.
• Global Service (No Modifier): When a radiologist owns the imaging equipment and performs the full service, they bill 72141 without any modifier.
• Modifier 59: May be needed if 72141 is billed with another spine MRI code on the same date and NCCI edits would bundle them. Always check current NCCI edit tables before applying modifier 59.

Incorrect modifier usage is a leading cause of claim rejections. For example, billing 72141-26 when the radiologist also owns the equipment would underpay the claim, while billing the global service when only the interpretation was performed would be fraudulent.

Documentation Requirements and Common Billing Pitfalls

To support a claim for 72141, the medical record must clearly document:

• The order for a cervical spine MRI without contrast.
• The clinical indication and relevant history (e.g., duration of symptoms, conservative treatment attempted).
• The radiology report stating that no contrast was administered and describing the findings.
• The date of service and the anatomical region imaged (cervical spine).

Common pitfalls that lead to denials include:

• Contrast mismatch: The order says "without contrast" but the report mentions contrast was given. Always code from the final report.
• Missing medical necessity: The diagnosis code does not meet payer coverage criteria. Verify LCDs and payer policies.
• Incorrect modifier: Using modifier 26 when the global service was provided, or vice versa.
• Unbundling: Billing 72141 and 72156 separately when they should be combined into 72156.
• Outdated codes: CPT codes are updated annually. Ensure you are using the current code set for the date of service.

Radiology practices can reduce denials by implementing a structured billing workflow that includes documentation review, coding verification, and pre-claim audits. Outsourcing to a specialized radiology billing company may also help manage payer-specific requirements.

Frequently Asked Questions About CPT 72141

Is it possible to have a cervical spine MRI without contrast?

Yes. In fact, most cervical spine MRIs are performed without contrast. Non-contrast MRI provides excellent detail of discs, nerves, and the spinal cord for common conditions like herniated discs and stenosis. Contrast is only needed when there is suspicion of infection, tumor, or certain post-surgical changes.

What is the ICD-10 code for a cervical spine MRI without contrast?

There is no single ICD-10 code for the procedure itself; ICD-10 codes describe the patient's diagnosis or condition. Common diagnosis codes paired with 72141 include those for cervical disc disorders (e.g., M50.xx), cervical radiculopathy (M54.12), and cervical spinal stenosis (M48.02). The specific code depends on the clinical indication and must be supported by documentation.

What are the CPT codes for MRI procedures in 2026?

CPT codes are updated annually, but as of the current code set, the cervical spine MRI codes remain 72141 (without contrast), 72142 (with contrast), and 72156 (without and with contrast). Always verify the code set applicable to the date of service, as changes can occur.

What is a cervical spine MRI used for?

A cervical spine MRI is used to evaluate neck pain, radiculopathy (pinched nerve), myelopathy (spinal cord compression), disc herniation, spinal stenosis, and other structural abnormalities. It provides detailed images of the vertebrae, discs, spinal cord, and nerve roots without ionizing radiation.

What is the difference between 78815 and 78816?

CPT codes 78815 and 78816 are for positron emission tomography (PET) imaging, not MRI. They are unrelated to cervical spine MRI and should not be confused with 72141.

What is the CPT code for MRI guidance?

MRI guidance codes are separate from diagnostic MRI codes. For example, CPT 77021 is for MRI guidance during needle placement (e.g., biopsy). These codes are used in addition to the primary procedure code when MRI is used for guidance.

For further details, refer to the CPT 72141 reference guide or the AAPC code description. Additional coding guidance is available from radiology billing resources.
