M24.652 Ankylosis, left hip

Name of the Condition

• Ankylosis, left hip

Summary

Ankylosis of the left hip is a condition characterized by abnormal stiffness or immobility of the left hip joint due to abnormal adhesion or fusion of joint structures. It can limit range of motion and affect daily activities that require hip movement, such as walking or sitting.

Causes

Common causes include trauma or injury to the hip, chronic inflammatory conditions such as arthritis, prolonged immobility after surgery or injury, and connective tissue disorders. In some cases, the cause may be idiopathic (unknown).

Risk Factors

Risk factors include age (more common in older adults), a history of hip injuries, chronic arthritis, and conditions requiring prolonged immobilization, such as a cast or sling. Repetitive strain on the hip through occupation or activities may also increase risk.

Symptoms

Symptoms typically include hip stiffness, pain, limited movement, and sometimes visible swelling or deformity around the hip area. Pain may worsen with attempted motion or weight-bearing.

Diagnosis

Diagnosis may involve a physical examination, patient history assessment, and imaging tests such as X-rays or MRIs to evaluate joint structure and rule out other conditions. Range of motion tests may also be performed to assess mobility.

Treatment Options

Treatment may include physical therapy to improve mobility, medications for pain and inflammation, and in severe cases, surgical intervention to restore joint function. The approach depends on the underlying cause and severity of the condition.

Prognosis and Follow-Up

Prognosis varies based on the cause and extent of joint involvement. Early intervention and adherence to treatment plans can improve outcomes. Regular follow-up with a healthcare provider is important to monitor progress and adjust treatment as needed.

Complications

Complications may include persistent pain, reduced mobility, difficulty with daily activities, and potential development of secondary conditions such as muscle atrophy or joint degeneration if left untreated.

Lifestyle & Prevention

Maintaining a healthy weight, avoiding repetitive high-impact activities, and promptly treating hip injuries or inflammatory conditions may help reduce risk. Physical therapy exercises can aid in preserving joint function when appropriate.

When to Seek Professional Help

Seek medical attention if you experience persistent hip stiffness, pain, or limited movement that interferes with daily activities. Early evaluation can help prevent progression and improve treatment outcomes.

Tips for Medical Coders

Document the specific side (left hip) and any contributing factors, such as trauma or arthritis, to ensure accurate coding. Verify that the diagnosis aligns with clinical findings and imaging results. Use this code only when ankylosis is confirmed in the left hip.
