S92.123K Displaced fracture of body of unspecified talus, subsequent encounter for fracture with nonunion

Name of the Condition

• Displaced fracture of body of unspecified talus, subsequent encounter for fracture with nonunion

Summary

A displaced fracture of the body of the talus with nonunion is a break in the central portion of the talus bone where fragments are misaligned, and the fracture has failed to heal properly. This injury disrupts the ankle joint's structure, potentially affecting weight-bearing and mobility. The talus connects the foot to the lower leg and is critical for movement and stability. The term "subsequent encounter" indicates this is a follow-up visit for the fracture, and "nonunion" specifies the lack of healing progress.

Causes

Direct trauma to the ankle, such as falls, sports injuries, or motor vehicle accidents, is the primary cause. High-impact forces or twisting motions may lead to this type of fracture, particularly in activities involving sudden stops or changes in direction. Nonunion can result from inadequate initial treatment, poor blood supply to the bone, or excessive movement at the fracture site during healing.

Risk Factors

• Participation in high-impact sports or activities with ankle injury risk.
• Osteoporosis or conditions weakening bone density.
• Previous ankle or talus injuries.
• Inadequate protective gear during physical activities.
• Smoking or other factors impairing bone healing.

Symptoms

• Persistent pain and swelling around the ankle.
• Difficulty bearing weight on the affected foot.
• Bruising and tenderness at the fracture site.
• Possible deformity or abnormal positioning of the foot.
• Limited range of motion in the ankle.

Diagnosis

A healthcare provider performs a physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays or CT scans, are used to confirm the fracture, evaluate displacement, and assess for nonunion. Additional tests may include MRI to evaluate soft tissue or blood supply.

Treatment Options

Treatment depends on the severity of the nonunion and may include surgical intervention to realign and stabilize the bone, bone grafting to promote healing, or immobilization with a cast or brace. Physical therapy is often recommended to restore strength and mobility.

Prognosis and Follow-Up

Prognosis varies based on the extent of the nonunion and treatment response. Regular follow-up visits are necessary to monitor healing progress, and imaging may be repeated to assess bone union. Long-term outcomes depend on successful healing and rehabilitation.

Complications

• Chronic pain or arthritis in the ankle.
• Persistent instability or difficulty bearing weight.
• Infection (if surgical intervention is required).
• Nerve or blood vessel damage.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use appropriate protective gear during sports or physical activities.
• Maintain bone health through adequate nutrition and exercise.
• Follow post-treatment instructions to support healing.

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, or difficulty bearing weight, or if symptoms worsen after initial treatment. Prompt evaluation is important for managing nonunion and preventing further complications.

Tips for Medical Coders

This code is used for a subsequent encounter for a displaced fracture of the talus body with nonunion. Documentation should specify the fracture type, displacement, and nonunion status. Ensure the encounter is subsequent (not initial) and that nonunion is clearly documented to support code assignment.
