M21.25 Flexion deformity, hip

Name of the Condition

• Flexion deformity, hip

Summary

Flexion deformity of the hip is a condition where the hip joint is persistently bent, reducing its range of motion. This limits the ability to fully extend the leg and may lead to discomfort or mobility issues.

Causes

Flexion deformity of the hip can result from prolonged immobility, trauma, or underlying conditions such as arthritis, neuromuscular disorders, or post-surgical complications. Abnormal muscle or tendon tightness, contractures, or chronic inflammation may also contribute to its development.

Risk Factors

• Age-related joint degeneration
• History of hip injuries or surgeries
• Chronic conditions affecting joint or muscle function
• Prolonged immobilization or poor posture
• Genetic predisposition to musculoskeletal abnormalities

Symptoms

• Persistent bending of the hip joint
• Limited ability to fully extend the leg
• Pain or discomfort in the hip area
• Uneven gait or difficulty walking
• Visible asymmetry or abnormal positioning

Diagnosis

Diagnosis involves a physical examination to assess joint alignment and range of motion. Imaging studies, such as X-rays or MRI, may be used to evaluate bone and soft tissue structures. Clinical history and underlying conditions are also considered.

Treatment Options

• Physical therapy to improve joint mobility and strength
• Use of braces or orthotic devices
• Pain management with medications
• Surgery in severe cases to correct the deformity

Prognosis and Follow-Up

With appropriate treatment, many individuals see improvement in mobility and comfort. Regular follow-ups may be necessary to monitor the condition and adjust treatment as needed.

Complications

• Chronic pain or stiffness
• Reduced mobility or functional limitations
• Increased risk of falls or injuries
• Potential for secondary joint degeneration

Lifestyle & Prevention

• Maintain regular physical activity to support joint health
• Practice proper posture and body mechanics
• Avoid prolonged immobility or bed rest when possible
• Manage underlying conditions that may contribute to deformity

When to Seek Professional Help

Seek medical attention if you experience persistent hip pain, limited mobility, or difficulty walking. Early evaluation can help prevent progression and improve outcomes.

Tips for Medical Coders

Document the specific hip affected (e.g., right, left, or unspecified) and any underlying causes or contributing factors. Ensure clinical documentation supports the diagnosis and severity to justify coding and billing.
