S92.124K Nondisplaced fracture of body of right talus, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of body of right talus, subsequent encounter for fracture with nonunion

Summary

A nondisplaced fracture of the body of the right talus is a break in the central portion of the talus bone where the bone fragments remain in their normal anatomical position. This code describes a follow-up encounter for a fracture that has failed to heal (nonunion) after an initial injury. The talus is a critical bone in the ankle joint, and nonunion can impact weight-bearing and mobility, requiring ongoing medical management.

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 can lead to fractures of the talus body, particularly in activities involving sudden stops or changes in direction. Nonunion may occur due to inadequate immobilization, poor blood supply to the bone, or other factors affecting healing.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer) or activities with a risk of ankle injury.
• Osteoporosis or other conditions that weaken bone density.
• Previous ankle or talus injuries.
• Inadequate protective gear during physical activities.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent pain in the ankle or foot, often worsening with activity.
• Swelling and bruising around the injury site.
• Difficulty bearing weight or walking.
• Limited range of motion in the ankle joint.
• Possible instability or clicking sensations in the ankle.

Diagnosis

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

Treatment Options

• Immobilization using a cast or boot to restrict movement and support healing.
• Surgical intervention, such as bone grafting or internal fixation, to promote union.
• Pain management with over-the-counter or prescribed medication.
• Physical therapy to restore mobility and strength once healing progresses.

Prognosis and Follow-Up

The prognosis depends on the severity of the nonunion and the effectiveness of treatment. With appropriate intervention, many patients achieve successful healing, but recovery may be prolonged. Regular follow-up visits and imaging are typically required to monitor progress.

Complications

• Chronic pain or arthritis in the ankle joint.
• Persistent instability or difficulty bearing weight.
• Infection (if surgery is performed).
• Delayed or failed healing requiring additional treatment.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use proper footwear and protective gear during sports or physical activities.
• Maintain bone health through a balanced diet and regular exercise.
• Follow post-injury care instructions to support healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to bear weight, or if symptoms worsen after an initial injury. Contact your provider if you notice persistent pain, instability, or signs of infection (e.g., redness, fever) during recovery.

Tips for Medical Coders

This code is used for a subsequent encounter for a nondisplaced fracture of the body of the right talus with nonunion. Documentation should specify the fracture type, laterality (right), and the presence of nonunion. Ensure the encounter is classified as "subsequent" and that the nonunion is clearly documented to support code assignment.
