ICD 10 for Neck Pain: Comprehensive Code List by Type

Neck pain is one of the most common musculoskeletal complaints seen in clinical practice. Whether due to injury, degeneration, or referred pain from other structures, accurate diagnosis and documentation are critical for proper treatment and insurance billing. In the United States, the International Classification of Diseases, 10th Revision (ICD-10), is used to standardize medical coding across healthcare systems. Understanding the correct ICD-10 codes for neck pain ensures accurate communication, effective treatment planning, and successful reimbursement.

This comprehensive guide outlines the various ICD-10 codes associated with neck pain, categorized by type—acute, chronic, cervicalgia, radiculopathy, traumatic, and more. We’ll also explore how these codes are applied in clinical settings, why specificity matters, and how healthcare providers can avoid common coding errors.

What Is ICD-10 and Why Is It Important?

The ICD-10 is a globally recognized diagnostic tool developed by the World Health Organization (WHO). It provides a standardized system for classifying diseases, symptoms, and medical conditions. In the U.S., the ICD-10-CM (Clinical Modification) version is used for diagnostic coding in all healthcare settings.

For neck pain, accurate ICD-10 coding helps in:

Incorrect or vague coding can lead to claim denials, delayed payments, and even audits. That’s why selecting the right ICD-10 code based on the specific type, location, and cause of neck pain is essential.

Common ICD-10 Codes for General Neck Pain

The most frequently used ICD-10 code for neck pain is M54.2 – Cervicalgia. This code describes neck pain without a specified cause and is often used when no underlying pathology such as disc herniation or spinal stenosis is identified.

M54.2 – Cervicalgia is appropriate when a patient presents with:

While M54.2 is widely used, it should not be overused as a default code. Payers and auditors often scrutinize this code because it lacks specificity. If a more precise diagnosis is available (e.g., whiplash, cervical spondylosis), a more detailed code should be assigned.

Acute vs. Chronic Neck Pain: Understanding the Difference

Neck pain can be classified as either acute or chronic, and ICD-10 coding should reflect this distinction when possible.

Acute Neck Pain

Acute neck pain typically lasts less than 6 weeks and is often due to muscle strain, minor injury, or recent trauma. While there is no specific ICD-10 code labeled 'acute neck pain,' M54.2 remains the most commonly used code. However, providers are encouraged to document the acute nature of the condition in the clinical notes to support medical necessity.

For trauma-related acute neck pain, such as from a motor vehicle accident, consider:

These injury codes are more specific and should be used when trauma is the documented cause.

Chronic Neck Pain

Chronic neck pain persists for more than 12 weeks and may be associated with degenerative conditions, poor posture, or unresolved injuries. Although ICD-10 does not have a dedicated code for 'chronic neck pain,' providers often use M54.2 with a note indicating chronicity.

When chronic neck pain is due to identifiable conditions, use more specific codes such as:

Using these more precise codes helps justify long-term treatment plans and supports medical necessity for physical therapy or other interventions.

Cervical Radiculopathy: Nerve-Related Neck Pain

Cervical radiculopathy occurs when a nerve root in the neck is compressed or irritated, causing pain that radiates into the shoulder, arm, or hand. This condition is often due to herniated discs, bone spurs, or spinal stenosis.

The primary ICD-10 code for cervical radiculopathy is M54.12. This code should be used when:

For more detail, subcategories under M50 (Cervical disc disorders) can be used if the underlying cause is known:

These codes provide greater specificity and are often required by insurance companies for authorization of imaging or specialist referrals.

Whiplash and Traumatic Neck Injuries

Whiplash is a common cause of neck pain, especially after motor vehicle accidents. It involves sudden hyperextension and flexion of the neck, leading to soft tissue injury.

The appropriate ICD-10 codes for whiplash depend on the severity and structures involved:

Note: The 7th character extension (A, D, or S) is mandatory and indicates the phase of treatment:

Additional codes may be needed to capture associated symptoms:

Always document the mechanism of injury (e.g., 'rear-end motor vehicle collision') to support accurate coding and billing.

Neck Pain Due to Degenerative Disc Disease and Spondylosis

As people age, the cervical spine undergoes degenerative changes that can lead to chronic neck pain. Common conditions include cervical spondylosis, disc degeneration, and spinal stenosis.

Key ICD-10 codes include:

For spondylosis (degenerative joint disease of the spine):

These codes allow for precise documentation of the affected spinal level and associated complications, improving care coordination and reimbursement potential.

Neck Pain with Headache and Referred Symptoms

Neck pain is frequently associated with headaches, particularly cervicogenic headaches—those originating from disorders of the neck but perceived as head pain.

The appropriate ICD-10 code for cervicogenic headache is G44.86 – Cervicogenic headache. This code should be used when:

Do not confuse cervicogenic headache with tension-type or migraine headaches. Using G44.86 ensures proper classification and may support the need for physical therapy or cervical spine interventions.

In some cases, both neck pain and headache codes may be billed together. For example:

Always ensure that both diagnoses are documented in the medical record to justify dual coding.

Referred Neck Pain: When the Source Isn't the Neck

Not all neck pain originates in the cervical spine. Pain can be referred from other areas such as the heart, lungs, or gastrointestinal system.

Examples of referred neck pain and their ICD-10 codes:

It’s crucial to rule out life-threatening causes of neck pain, especially when accompanied by symptoms like shortness of breath, sweating, or nausea. Accurate coding in these cases supports timely interventions and appropriate referrals.

Post-Surgical Neck Pain

Patients who have undergone cervical spine surgery may experience persistent or new-onset neck pain. This is known as failed back surgery syndrome (FBSS) when it occurs after spinal procedures.

Applicable ICD-10 codes include:

Always link post-surgical pain to the original procedure and document whether the pain is typical healing discomfort or a complication. This distinction affects coding and treatment decisions.

Neck Pain in Children and Adolescents

While less common, neck pain in younger patients can result from sports injuries, poor posture (e.g., 'text neck'), or congenital conditions.

Common codes include:
