M24.651 Ankylosis, right hip

Name of the Condition

• Ankylosis, right hip

Summary

Ankylosis of the right hip is a condition characterized by abnormal stiffness or immobility of the right hip joint due to abnormal adhesion and rigidity of the joint structures. It can limit range of motion and affect daily activities that require hip movement.

Causes

Common causes include trauma or injury to the hip joint, 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 joint stiffness, pain, limited movement, and sometimes visible swelling or deformity around the hip area. In severe cases, the hip may become completely immobile.

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 some cases, surgical intervention to restore joint function.

Prognosis and Follow-Up

Prognosis depends on the underlying cause and severity of the ankylosis. 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 chronic pain, reduced quality of life, difficulty with mobility, and potential development of secondary joint issues due to altered movement patterns.

Lifestyle & Prevention

Maintaining a healthy weight, avoiding excessive strain on the hip, and engaging in regular low-impact exercise can help reduce risk. Prompt treatment of hip injuries or inflammatory conditions may prevent progression to ankylosis.

When to Seek Professional Help

Seek medical attention if you experience persistent hip stiffness, pain, or reduced mobility that interferes with daily activities. Early evaluation can help prevent worsening of the condition.

Tips for Medical Coders

When coding for ankylosis of the right hip (M24.651), ensure documentation specifies the affected side and joint. Include details about the underlying cause, if known, and any associated symptoms or complications to support accurate code assignment.
