M54.1 is a non-billable ICD-10-CM code for radiculopathy; use specific subcodes like M54.12 or M54.16 for accurate diagnosis and reimbursement.

What is M54.1 – Radiculopathy code?

M54.1 is a general ICD-10-CM diagnosis code used to describe radiculopathy, a condition involving nerve root irritation or compression along the spinal nerve root. This disorder is typically marked by radicular pain, sensory loss referable to a specific body region, or weakness in the muscles served by the structures innervated by the involved nerve.

As of the 2025 ICD-10-CM coding guidelines, M54.1 is now non-billable for reimbursement purposes due to its lack of specificity. Providers must instead use more detailed subcodes that indicate the exact site of the radiculopathy or involved nerve root.

M54.10 – Radiculopathy, site unspecified
M54.11 – Radiculopathy, occipito-atlanto-axial region
M54.12 – Radiculopathy, cervical region
M54.16 – Radiculopathy, lumbar region
M54.17 – Radiculopathy, lumbosacral region
M54.18 – Radiculopathy, sacral and sacrococcygeal region

These specific, billable subcodes ensure accurate documentation and reimbursement for patient encounters involving radiculopathy.

Is M54.1 billable?

To ensure proper documentation and billing, use the following specific and billable diagnosis codes in place of M54.1:

M54.10 – Radiculopathy, site unspecified
M54.11 – Radiculopathy, occipito-atlanto-axial region
M54.12 – Radiculopathy, cervical region
M54.16 – Radiculopathy, lumbar region
M54.17 – Radiculopathy, lumbosacral region
M54.18 – Radiculopathy, sacral and sacrococcygeal region

These codes are essential for insurance claims, reimbursement purposes, and EHR documentation.

Clinical information

Radiculopathy is part of the broader musculoskeletal system disorders and often results from compression-related conditions like:

Intervertebral disc disorder (especially disc herniation)
Cervical disc degeneration
Lumbar and other intervertebral disc displacement
Cervical disc disorder with myelopathy
Trauma or lesions affecting the thoracic spine or connective tissue

Common clinical manifestations include pain, sensory loss, tingling, and muscle weakness along the affected spinal nerve root. Diagnostic confirmation often requires imaging such as MRI or CT scans to assess the intervertebral disc and nerve root involvement.

Treatment for radiculopathy or neuritis or radiculitis varies based on the region involved (e.g., cervical region, thoracolumbar region, or thoracic region) and the severity of symptoms. Approaches include:

Conservative care: rest, NSAIDs, and physical therapy
Epidural steroid injections: to reduce inflammation around the involved nerve root
Surgical options: Optoins such as discectomy or spinal decompression, for persistent or worsening symptoms

Synonyms include

Radiculopathy may also be coded or described under terms such as:

Nerve root disorder
Pinched nerve
Radiculopathy brachial radiculitis NOS
Radiculitis NOS lumbosacral neuritis
Radiculitis NOS thoracic neuritis
Neuralgia and neuritis NOS
Brachial neuritis
Neuritis NOS
Psychogenic dorsalgia
Back pain and low back pain

Other ICD-10 Codes commonly used for radiculopathy

M50.00 – Cervical disc disorder with myelopathy, unspecified region
M50.30 – Cervical disc degeneration, unspecified cervical region
M99.03 – Segmental and somatic dysfunction of the lumbar region
M54.5 – Low back pain, often seen as a symptom of lumbar radiculopathy
M54.2 – Cervicalgia, related to neck pain and possible nerve root involvement
