ICD 10 Code for Neck Pain: Cervicalgia & Associated Codes

Neck pain is one of the most common musculoskeletal complaints affecting adults worldwide. Whether caused by poor posture, injury, degeneration, or underlying medical conditions, it can significantly impact daily life and work productivity. For healthcare providers, accurate diagnosis and proper documentation are essential — not only for effective treatment but also for billing, insurance claims, and public health statistics. This is where the International Classification of Diseases, 10th Revision (ICD-10), comes into play.

In this comprehensive guide, we'll explore the ICD-10 code for neck pain, specifically focusing on cervicalgia and its associated codes. We’ll also discuss the clinical significance, differential diagnosis, documentation tips, and how these codes are used in medical practice.

What Is Cervicalgia?

The term cervicalgia refers to pain in the cervical spine — the region of the spine that makes up the neck. It is derived from the Latin word 'cervix,' meaning neck, and the Greek suffix '-algia,' meaning pain. Unlike conditions such as radiculopathy or myelopathy, cervicalgia does not involve nerve root compression or spinal cord dysfunction. It is generally used to describe localized neck pain without radiating symptoms.

Cervicalgia can be acute or chronic. Acute cervicalgia typically lasts less than six weeks and is often caused by muscle strain, trauma, or sudden movements (such as whiplash). Chronic cervicalgia persists for more than three months and may be associated with degenerative changes in the cervical spine, poor ergonomics, or repetitive stress.

ICD-10 Code for Cervicalgia: M54.2

The primary ICD-10-CM code for neck pain or cervicalgia is M54.2. This code is classified under:

M54.2 is a billable and specific code that can be used for reimbursement purposes. It is used to indicate a diagnosis of neck pain when no other underlying condition is identified. However, it's important to note that using M54.2 requires clinical justification. Simply documenting 'neck pain' without further evaluation may not be sufficient for insurance payers.

Key Features of M54.2

When to Use M54.2: Clinical Scenarios

Healthcare professionals use M54.2 in various clinical situations. Common scenarios include:

However, if imaging or clinical findings reveal a specific condition such as cervical disc herniation, spinal stenosis, or arthritis, a more specific ICD-10 code should be used instead of M54.2.

Associated ICD-10 Codes for Neck Pain

While M54.2 is the primary code for nonspecific neck pain, several other ICD-10 codes are associated with neck pain, depending on the underlying cause. Accurate coding ensures proper clinical documentation and facilitates appropriate treatment and reimbursement.

1. Cervical Radiculopathy (M54.12)

M54.12 is used when neck pain is accompanied by radiating pain into the shoulder, arm, or hand due to nerve root compression. This condition is often caused by a herniated disc, spinal stenosis, or degenerative disc disease in the cervical spine.

Symptoms may include:

Using M54.12 instead of M54.2 provides more specificity and supports the medical necessity of advanced diagnostics like MRI or EMG studies.

2. Cervical Disc Disorders

Cervical disc issues are common causes of neck pain. The ICD-10 includes several codes under category M50 for cervical disc disorders:

These codes specify the exact type of disc pathology and associated neurological complications. For example, M50.12 is used when a cervical disc herniation causes radiculopathy on the right side, while M50.13 would indicate left-side involvement.

3. Cervical Spondylosis (M47.812)

M47.812 refers to spondylosis of the cervical region. Cervical spondylosis, also known as cervical osteoarthritis, is a degenerative condition affecting the discs and joints in the neck. It is common in older adults and may cause chronic neck pain, stiffness, and reduced range of motion.

If spondylosis leads to spinal stenosis or nerve compression, more specific codes such as M47.12 (spondylosis with myelopathy) or M47.22 (spondylosis with radiculopathy) should be used.

4. Whiplash-Associated Disorders (S13.4XXA, S13.4XXD)

Whiplash injuries, commonly resulting from rear-end motor vehicle collisions, often present with neck pain. The appropriate ICD-10 codes fall under the injury chapter (S00–T98).

These codes capture the traumatic nature of the injury and the phase of treatment. Using trauma-related codes instead of M54.2 reflects the etiology and supports documentation for auto insurance or workers’ compensation claims.

5. Cervical Strain or Sprain (S16.1XXA)

Muscle strain or ligament sprain in the neck can be coded as S16.1XXA for an initial encounter. This is more specific than M54.2 and is appropriate when trauma or overuse is the clear cause.

6. Facet Joint Syndrome (M53.8)

Cervical facet joint pain, also known as zygapophyseal joint pain, may be coded under M53.8 – Other specified dorsopathies. While not a direct neck pain code, it is used when facet joint arthritis or dysfunction is diagnosed through physical examination or imaging.

7. Torticollis (M43.6)

M43.6 is used for acquired torticollis — a condition where the neck muscles contract abnormally, causing the head to twist or tilt. It can result from muscle spasms, congenital issues, or neurological disorders. Neck pain is a common symptom.

8. Cervical Myofascial Pain (M79.1)

M79.1 – Myofascial pain syndrome — is used when neck pain is due to trigger points in the muscles, often associated with muscle tension, overuse, or poor posture. This code is more specific than M54.2 and may justify physical therapy or trigger point injections.

9. Referred Pain from Other Areas

Neck pain can sometimes be referred from other regions, such as the heart (in angina or myocardial infarction) or the gallbladder. In such cases, the underlying condition should be coded, and neck pain documented as a symptom.

It’s crucial to rule out life-threatening causes of neck pain, especially when accompanied by chest pain, shortness of breath, or other systemic symptoms.

ICD-10 Coding Guidelines for Neck Pain

Proper use of ICD-10 codes requires adherence to official coding guidelines published by the Centers for Medicare & Medicaid Services (CMS) and the American Hospital Association (AHA). Here are key principles to follow:

1. Specificity Is Key

Always use the most specific code available. If a patient has neck pain due to cervical disc herniation with radiculopathy, code M50.12 instead of M54.2. Nonspecific codes like M54.2 should only be used when a definitive diagnosis cannot be established after appropriate evaluation.

2. Combination Codes

Some conditions have combination codes that include both the disease and associated symptoms. For example, M50.12 includes both the cervical disc disorder and radiculopathy. Avoid coding M54.2 and M50.12 together, as this would be redundant.

3. Laterality Matters

Many cervical spine codes require specification of laterality (right, left, or bilateral). For example:

Always document laterality in the clinical notes to support accurate coding.

4. Encounter Type

For injuries, the 7th character extension indicates the type of encounter:

For example, S13.4XXA is used for the first visit after a whiplash injury, while S13.4XXD is used for follow-up visits during recovery.

5. Avoid Overuse of M54.2

While M54.2 is convenient, overuse can lead to claim denials or audits. Payers may require supporting documentation such as physical exam findings, imaging reports, or treatment plans to justify the use of a nonspecific code.

Documentation Tips for Accurate Neck Pain Coding

Strong clinical documentation is the foundation of accurate ICD-10 coding. Here are essential elements to include when evaluating a patient with neck pain:
