Neck Pain ICD 10 Code: Everything You Need to Know

Neck pain is one of the most common musculoskeletal complaints reported by patients across all age groups. Whether caused by poor posture, injury, degenerative conditions, or underlying diseases, neck pain can significantly impact daily life, productivity, and overall well-being. For healthcare providers, accurate diagnosis and proper documentation are essential—not only for effective treatment but also for medical billing and insurance purposes. The International Classification of Diseases, 10th Revision (ICD-10), provides standardized codes to classify and report medical conditions, including neck pain.

What is the ICD-10 Code for Neck Pain?

The primary ICD-10 code used to classify neck pain is M54.2. Officially titled 'Cervicalgia,' this code refers to pain in the neck without a specific underlying structural cause. It is a symptom-based diagnosis used when no definitive pathology such as disc herniation, spinal stenosis, or fracture is identified as the root cause.

ICD-10 Code M54.2 – Cervicalgia
- Category: Other dorsopathies
- Subcategory: Pain in the neck
- Billable: Yes
- Valid for submission: 2024 (October 1, 2023 – September 30, 2024)

This code is widely accepted by insurance providers and is used in medical records, claims, and electronic health records (EHRs) across the United States and other countries that have adopted ICD-10 coding standards.

Understanding Neck Pain: Causes and Symptoms

Before diving deeper into coding, it’s important to understand the clinical picture behind neck pain. Neck pain, also known as cervical pain, can range from mild discomfort to severe, debilitating pain. It may be acute (lasting less than six weeks), subacute (six to 12 weeks), or chronic (more than 12 weeks).

Common Causes of Neck Pain

Symptoms Associated with Neck Pain

Patients may experience a variety of symptoms, including:

Depending on the nature and cause of the pain, healthcare professionals may use more specific ICD-10 codes beyond M54.2 to reflect associated conditions.

Related ICD-10 Codes for Neck Pain Conditions

While M54.2 is the most common code for nonspecific neck pain, there are several related codes used when a more specific diagnosis is established. Proper coding ensures accurate documentation and appropriate reimbursement.

M54.12 – Radiculopathy, Cervical Region

When neck pain is accompanied by nerve root irritation or compression—commonly due to a herniated disc or spinal stenosis—M54.12 should be used. This code indicates radiating pain, numbness, or weakness along the cervical nerve pathway.

M50.1 – Cervical Disc Displacement, Without Myelopathy

Used when imaging confirms disc displacement (protrusion or herniation) in the cervical spine without spinal cord involvement. This includes subcategories like M50.1X1A (initial encounter) or M50.1X1D (subsequent encounter).

M50.2 – Other Cervical Disc Disorders

This category includes degenerative disc disease, spondylosis, and other non-displaced disc pathologies affecting the neck.

S13.4 – Sprain of Joints and Ligaments of the Cervical Spine

Applicable in cases of trauma such as whiplash or sports injuries where ligaments are stretched or torn.

M47.812 – Spondylosis of the Cervical Region with Radiculopathy

Used when degenerative changes in the spine lead to nerve root compression and associated symptoms.

R52 – Unspecified Pain

A general code for pain when location or cause is unclear. However, R52 is less specific and generally discouraged when a more precise code (like M54.2) is applicable.

Why Accurate ICD-10 Coding Matters

Accurate coding is vital for several reasons:

Using M54.2 appropriately—only when neck pain is the primary symptom and no definitive pathology is found—maximizes claim acceptance and reflects clinical judgment accurately.

When to Use M54.2 vs. Other Neck Pain Codes

Choosing the correct ICD-10 code depends on the clinical findings. Here’s a guide to help differentiate:

Use M54.2 – Cervicalgia When:

Use a More Specific Code When:

For example, if a patient presents with neck pain and an MRI reveals a C5-C6 disc herniation causing right arm pain, the appropriate code would be M50.1X1A (Cervical disc displacement, initial encounter), not M54.2.

Documentation Tips for M54.2

To support the use of M54.2, clinicians should document:

Clear and consistent documentation reduces the risk of claim denials and supports medical necessity.

Common Coding Errors and How to Avoid Them

Despite its simplicity, M54.2 is often misused. Here are common pitfalls and how to avoid them:

1. Using M54.2 When a More Specific Code is Available

One of the most frequent errors is using M54.2 when a definitive diagnosis exists. For instance, if a patient has cervical radiculopathy due to a confirmed herniated disc, coding M54.2 instead of M54.12 or M50.1 may lead to denied claims.

Solution: Always correlate symptoms with diagnostic findings. Use the most specific code supported by clinical evidence.

2. Confusing Neck Pain with Back Pain

Neck pain is coded under cervical conditions, while back pain refers to the thoracic or lumbar spine. Using lumbar spine codes (e.g., M54.5 for low back pain) for neck pain is incorrect.

Solution: Clearly identify the anatomical region. Neck = cervical = M54.2 or related cervical codes.

3. Overuse of Unspecified Codes Like R52

Some providers default to R52 (unspecified pain) when they’re unsure. However, R52 lacks specificity and may trigger payer scrutiny.

Solution: If pain is in the neck and no cause is found, M54.2 is more appropriate than R52.

4. Failing to Update Codes for Chronic or Acute Phases

Some codes require specification of encounter type (initial, subsequent, or sequela). For example, trauma-related neck pain may need S13.4XXA for the initial visit and S13.4XXD for follow-up.

Solution: Stay updated on ICD-10 guidelines and use seventh characters when required.

Neck Pain and ICD-10 in Physical Therapy

Physical therapists frequently treat patients with neck pain. Proper coding is essential for treatment authorization and progress tracking.

M54.2 is commonly used in physical therapy settings when treating nonspecific mechanical neck pain. It supports medical necessity for modalities like manual therapy, therapeutic exercises, and posture training.

However, if a patient is referred for cervical radiculopathy, the therapist should use M54.12 and coordinate with the referring physician to ensure coding alignment.

Many insurance plans require a precise diagnosis code to approve therapy sessions. Therefore, accurate documentation and coding at intake can prevent claim delays.

Neck Pain in Chiropractic Care

Chiropractors also rely heavily on ICD-10 codes for billing. M54.2 is a standard code for cervical spine manipulation due to mechanical neck pain.

However, payers such as Medicare and private insurers may have specific requirements for chiropractic services. For example:

Using M54.2 without clinical rationale may result in claim denials. Therefore, chiropractors should document range of motion, pain levels, functional limitations, and treatment response.

Neck Pain Due to Occupational Causes

Work-related neck pain—often due to repetitive motion, prolonged computer use, or heavy lifting—may require special coding considerations.
