M47.2 – Spondylosis with Radiculopathy
M47.2 is the ICD-10 code for spondylosis with radiculopathy – a degenerative spinal condition in which bony or disc changes compress nerve roots, causing pain, tingling, or weakness.
Things worth knowing about "M47.2"
M47.2 is the ICD-10 code for spondylosis with radiculopathy – a degenerative spinal condition in which bony or disc changes compress nerve roots, causing pain, tingling, or weakness.
What is M47.2?
The ICD-10 code M47.2 refers to spondylosis with radiculopathy. This is a degenerative condition of the spine in which age-related or wear-related changes – such as bone spurs (osteophytes), disc protrusions, or narrowing of the spinal canal – compress or irritate one or more nerve roots that branch off from the spinal cord. Radiculopathy describes the resulting nerve root irritation or damage, which can cause radiating pain, sensory disturbances, or muscle weakness.
Causes
M47.2 results from gradual degeneration of the spinal structures. Common contributing factors include:
- Degeneration of intervertebral discs (loss of height and hydration)
- Formation of osteophytes (bony outgrowths at the vertebral margins)
- Thickening of spinal ligaments (e.g., ligamentum flavum)
- Narrowing of the neural foramina (openings through which nerve roots exit the spine)
- Chronic poor posture, heavy physical labor, or prolonged inactivity
- Previous spinal injuries or trauma
Symptoms
The specific symptoms depend on which part of the spine is affected. Common symptoms include:
- Radiating pain into the arm or leg, depending on the affected spinal segment
- Numbness, tingling, or a burning sensation along the distribution of the affected nerve
- Muscle weakness in the arm or leg
- Neck or back pain
- Reduced range of motion in the spine
- In severe cases: loss of reflexes or coordination difficulties
Commonly Affected Spinal Regions
- Cervical spine (neck): Pain radiates into the shoulder, arm, or hand
- Lumbar spine (lower back): Pain radiates into the buttock, leg, or foot (similar to sciatica)
Diagnosis
The diagnosis of M47.2 is established through clinical evaluation and imaging studies:
- Medical history and physical examination: Assessment of reflexes, muscle strength, and sensation
- X-ray: Detection of osteophytes, disc space narrowing, and vertebral misalignment
- MRI (Magnetic Resonance Imaging): Detailed visualization of soft tissues, discs, and nerve roots
- CT (Computed Tomography): Evaluation of bony structures and canal narrowing
- Electrophysiological studies (e.g., EMG/NCV): Assessment of nerve conduction and function
Treatment
Treatment is tailored to the severity of symptoms and the affected spinal region. The primary goals are pain relief, functional improvement, and prevention of further deterioration.
Conservative Treatment
- Physical therapy: Targeted exercises to strengthen core and back muscles, stretching, and postural correction
- Pain medications: NSAIDs (e.g., ibuprofen, diclofenac), muscle relaxants, or analgesics
- Nerve root injections: Corticosteroid injections near the affected nerve root (perineural infiltration)
- Heat and cold therapy
- Orthopedic aids: e.g., cervical collar (short-term use) or orthopedic insoles
Surgical Treatment
Surgery may be considered in cases of severe nerve damage, persistent symptoms despite conservative treatment, or a risk of permanent neurological deficit. Common procedures include:
- Nerve root decompression (e.g., foraminotomy)
- Disc surgery (e.g., discectomy)
- Spinal fusion (spondylodesis) in selected cases
Prognosis
The condition is often chronic but can be effectively managed with consistent treatment. Many patients experience significant improvement in quality of life through physical therapy and medication. Early intervention can help slow disease progression and prevent irreversible nerve damage.
