M76.10 Psoas tendinitis, unspecified hip

Name of the Condition

Psoas Tendinitis, Unspecified Hip

Summary

Psoas tendinitis is an inflammatory condition affecting the psoas tendon, which connects the psoas muscle to the hip. It involves irritation or microtears at the tendon-bone attachment site, often resulting from overuse or mechanical stress. This condition may cause pain and functional limitations in the hip and surrounding areas.

Causes

Psoas tendinitis commonly arises from repetitive stress or overuse of the hip, such as during activities involving hip flexion or extension. Direct trauma to the psoas tendon or sudden increases in physical activity can also trigger inflammation. Poor biomechanics or muscle imbalances may contribute to tendon strain over time.

Risk Factors

• Participation in activities requiring repetitive hip motion, such as running or climbing.
• Age-related tendon degeneration, which reduces tissue resilience.
• Previous hip injuries or conditions affecting the psoas tendon.
• Sedentary lifestyles followed by sudden increases in activity.

Symptoms

• Localized pain in the hip or groin area, often worsening with movement.
• Tenderness or swelling around the affected tendon attachment sites.
• Stiffness or reduced range of motion in the hip.
• Pain that intensifies during weight-bearing activities or prolonged sitting.

Diagnosis

Diagnosis is based on a physical examination to assess tenderness, swelling, and movement. Imaging, such as ultrasound or MRI, may be used to evaluate tissue damage or inflammation at the tendon-bone junction.

Treatment Options

• Rest and activity modification to reduce strain on the psoas tendon.
• Physical therapy to strengthen surrounding muscles and improve biomechanics.
• Nonsteroidal anti-inflammatory drugs (NSAIDs) to manage pain and inflammation.
• Corticosteroid injections for severe or persistent symptoms.
• Surgical intervention in rare cases of chronic or refractory tendinitis.

Prognosis and Follow-Up

Most cases of psoas tendinitis improve with conservative treatment, though recovery time varies. Follow-up care may include monitoring for symptom resolution and adjusting activity levels to prevent recurrence. Persistent or worsening symptoms may require further evaluation.

Complications

• Chronic pain or functional impairment if left untreated.
• Tendon degeneration or rupture in severe cases.
• Reduced mobility or difficulty with daily activities.

Lifestyle & Prevention

• Maintain proper posture and biomechanics during physical activities.
• Gradually increase activity intensity to avoid overuse injuries.
• Incorporate stretching and strengthening exercises for hip and core muscles.
• Use ergonomic support during prolonged sitting or standing.

When to Seek Professional Help

Seek medical attention if pain is severe, persistent, or worsening; if mobility is significantly limited; or if symptoms interfere with daily activities. Prompt evaluation is recommended for acute trauma or sudden onset of symptoms.

Tips for Medical Coders

Use M76.10 for psoas tendinitis of the unspecified hip. Ensure documentation specifies the affected hip (unspecified) and confirms the diagnosis through clinical evaluation. Avoid using this code for bilateral or site-specific hip involvement, as other codes may apply.
