S92.015K Nondisplaced fracture of body of left calcaneus, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of body of left calcaneus, subsequent encounter for fracture with nonunion

Summary

This condition refers to a break in the body of the left calcaneus (heel bone) where the bone fragments remain aligned, but healing has not occurred as expected during a subsequent encounter. Nonunion indicates the fracture site has failed to progress toward union, often requiring additional evaluation and management to promote healing and restore function.

Causes

The initial fracture typically results from high-impact trauma, such as falls from a height or direct force to the heel. Nonunion may develop due to inadequate immobilization, poor blood supply to the fracture site, infection, or underlying health conditions that impair bone healing.

Risk Factors

• Delayed or inadequate initial treatment of the fracture.
• Poor blood circulation or smoking, which can hinder healing.
• Certain medical conditions, such as diabetes or osteoporosis, that affect bone repair.
• Excessive weight-bearing or activity before the fracture has healed.

Symptoms

• Persistent pain at the fracture site, often worsening with activity.
• Swelling or tenderness that does not resolve over time.
• Difficulty bearing weight on the affected foot, even with support.
• Possible instability or limited range of motion in the foot or ankle.

Diagnosis

Physical examination to assess pain, swelling, and functional limitations. Imaging tests, such as X-rays or CT scans, to evaluate the fracture site for signs of nonunion, including a persistent gap or lack of bone bridging. Additional tests may be used to assess blood flow or rule out infection.

Treatment Options

• Extended immobilization with a cast or brace to stabilize the fracture.
• Bone stimulation therapies, such as electrical or ultrasound devices, to promote healing.
• Surgical intervention, such as bone grafting or internal fixation, to encourage union.
• Pain management and physical therapy to maintain mobility and strength during recovery.

Prognosis and Follow-Up

Prognosis depends on the underlying cause of nonunion and the effectiveness of treatment. Regular follow-up with imaging is typically required to monitor healing progress. Recovery may be prolonged, and some patients may experience long-term functional limitations.

Complications

• Chronic pain or arthritis in the foot or ankle.
• Persistent instability or difficulty walking.
• Infection, particularly if surgical intervention is needed.
• Need for additional procedures if initial treatments are unsuccessful.

Lifestyle & Prevention

• Avoid high-impact activities until the fracture is fully healed.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Follow medical advice regarding weight-bearing restrictions and rehabilitation.
• Use proper footwear and avoid uneven surfaces to reduce fall risk.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or there are signs of infection (e.g., redness, warmth, or drainage). Prompt evaluation is important if weight-bearing becomes more difficult or if symptoms do not improve with conservative management.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with nonunion. Include details about the fracture's status, any treatments provided, and clinical findings supporting nonunion. Ensure documentation aligns with the code's specificity for the left calcaneus and the presence of nonunion.
