Musculoskeletal condition M47.14 — ICD-10 M47.14

ICD-10: M47.14 | Category: Spine Disorders | Billable: Yes

M47.14 refers to lumbar spondylosis with radiculopathy, a degenerative condition of the lumbar spine characterized by the degeneration of intervertebral discs and facet joints, leading to nerve root compression. This condition often manifests as pain, numbness, or weakness that radiates down the legs, typically following the distribution of affected nerve roots. It is essential for clinicians to recognize the clinical implications of this diagnosis, as it can significantly impact a patient's quality of life and functional abilities.

The lumbar spine consists of five vertebrae (L1-L5), intervertebral discs, ligaments, and muscles that provide stability and mobility. The intervertebral discs serve as shock absorbers between vertebrae, while facet joints allow for flexion, extension, and rotation.

Biomechanics

Normal lumbar biomechanics involve the distribution of loads during movement. The intervertebral discs maintain spinal alignment and absorb forces during activities such as lifting or bending. However, with age or injury, these structures can undergo degenerative changes that alter their mechanical properties, leading to increased stress on surrounding tissues.

Patient presents with neck pain and stiffness, with an MRI revealing cervical spondylosis. The physician documents that the patient is experiencing myelopathy symptoms. Code as M47.14 because the documentation clearly indicates cervical spondylosis (M47.1) with myelopathy, which aligns with the criteria specified in the ICD-10-CM guidelines for this code.

To support medical necessity for coding M47.14 and to prevent claim denials, the following documentation elements are critical:

• Clear diagnosis of cervical spondylosis with specific mention of any neurological involvement, such as myelopathy.
• Detailed patient history, including symptom duration, previous treatments, and response to therapy.
• Comprehensive physical examination findings, including neurological assessments and imaging results.
• Explicit treatment plans that link to the diagnosis, demonstrating the necessity of the interventions being provided.

Subjective: A 62-year-old female patient reports persistent neck pain and intermittent numbness in her hands. She states that the pain worsens with prolonged sitting and improves with movement. She has a history of arthritis. Objective: Physical examination reveals reduced range of motion in the cervical spine and positive Spurling’s test. MRI results indicate moderate cervical spondylosis with signs of myelopathy. Assessment: Cervical spondylosis with myelopathy (ICD-10 Code M47.14). Plan: Initiate physical therapy focusing on cervical stabilization exercises, recommend ergonomic adjustments at her workplace, and prescribe NSAIDs for pain management. Schedule a follow-up in 6 weeks to assess progress.

Differential diagnoses for lumbar spondylosis with radiculopathy include:

1. Herniated Nucleus Pulposus (M51.26): Often presents similarly but may involve acute onset of symptoms.
2. Lumbar Spinal Stenosis (M48.061): Characterized by narrowing of the spinal canal; symptoms may include claudication.
3. Sacroiliac Joint Dysfunction (M53.3): Pain localized to the sacroiliac joint area without radicular symptoms.
4. Facet Joint Syndrome (M53.8): Localized back pain without significant neurological findings.

Accurate documentation is vital for billing purposes related to M47.14:

Key Elements for Documentation

1. Detailed patient history including onset, duration, and severity of symptoms.
2. Results from physical examinations including neurological assessments.
3. Imaging findings that support the diagnosis of lumbar spondylosis with radiculopathy.

Billing Guidance

Ensure that documentation aligns with coding guidelines for M47.14:

• Use specific codes for any associated conditions (e.g., M54.16 for radicular pain).
• Document any treatments provided during visits to support billing claims effectively.
