M46.07 Spinal enthesopathy, lumbosacral region

Name of the Condition

• Spinal Enthesopathy, Lumbosacral Region

Summary

Spinal enthesopathy in the lumbosacral region refers to inflammation or degeneration at the sites where ligaments and tendons attach to the vertebrae in the lower spine, specifically involving the lumbar and sacral segments. This condition can cause pain, stiffness, and discomfort in the lower back and pelvic area.

Causes

Spinal enthesopathy in the lumbosacral region may result from mechanical stress, repetitive overuse, autoimmune diseases (such as ankylosing spondylitis), or previous injuries to the lower spine. In some cases, the exact cause remains unclear, but inflammation at the entheseal attachment sites is a key feature.

Risk Factors

• Age, particularly middle-aged and older adults.
• Genetic predisposition to autoimmune disorders.
• Occupations or activities involving repetitive bending, lifting, or twisting of the lower back.
• History of trauma or overuse of the lumbosacral spine.

Symptoms

• Localized pain and stiffness in the lower back and sacral region.
• Tenderness over affected entheses.
• Reduced mobility or flexibility in the lower spine.
• Possible radiating pain to the hips or legs.

Diagnosis

Diagnosis is typically made through a combination of patient history, physical examination, and imaging tests (e.g., X-rays or MRI) to detect changes at the entheses. Blood tests may be used to rule out inflammatory or autoimmune conditions.

Treatment Options

• Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation.
• Physical therapy to strengthen supporting muscles and improve flexibility.
• Corticosteroid injections for localized pain relief.
• Lifestyle modifications to avoid aggravating activities.

Prognosis and Follow-Up

Prognosis depends on the underlying cause and severity of the condition. With appropriate treatment, many patients experience symptom improvement, though chronic cases may require ongoing management. Regular follow-up is recommended to monitor symptoms and adjust treatment as needed.

Complications

• Chronic pain or disability if left untreated.
• Reduced mobility or functional impairment.
• Potential progression to other spinal conditions (e.g., spondylosis) in severe cases.

Lifestyle & Prevention

• Maintain a healthy weight to reduce spinal stress.
• Practice proper lifting techniques and avoid repetitive strain.
• Engage in regular low-impact exercise to strengthen core and back muscles.
• Use ergonomic support during prolonged sitting or standing.

When to Seek Professional Help

Seek medical attention if you experience persistent lower back pain, worsening stiffness, or radiating pain that interferes with daily activities. Prompt evaluation is important if symptoms are accompanied by numbness, weakness, or bowel/bladder changes.

Tips for Medical Coders

When coding for M46.07 (Spinal enthesopathy, lumbosacral region), ensure documentation specifies the lumbosacral location. Verify that the diagnosis aligns with clinical findings, such as imaging or physical exam results, to support the code assignment. Avoid using this code for unspecified spinal enthesopathy or other regional variants.
