S92.065P Nondisplaced intraarticular fracture of left calcaneus, subsequent encounter for fracture with malunion

Name of the Condition

• Nondisplaced intraarticular fracture of left calcaneus, subsequent encounter for fracture with malunion

Summary

A nondisplaced intraarticular fracture of the left calcaneus with malunion is a healed fracture of the left heel bone where the bone fragments remain aligned but have healed in a non-anatomic position, affecting the subtalar joint. This condition occurs during a subsequent encounter and may result in persistent pain, stiffness, or altered foot mechanics due to the malaligned joint surface.

Causes

The fracture initially results from high-impact trauma, such as falls from a height or motor vehicle accidents. Malunion develops if the fracture heals without proper alignment, often due to inadequate immobilization, delayed treatment, or insufficient follow-up care.

Risk Factors

• Inadequate initial fracture management or immobilization.
• Delayed or incomplete follow-up after the initial injury.
• Underlying bone conditions like osteoporosis that impair healing.
• High-impact activities or occupations that stress the heel during recovery.

Symptoms

• Chronic heel pain, especially with weight-bearing or uneven surfaces.
• Stiffness or limited range of motion in the subtalar joint.
• Altered gait or foot mechanics.
• Possible swelling or discomfort during activity.

Diagnosis

Physical examination to assess pain, joint mobility, and gait. Imaging tests, such as X-rays or CT scans, to evaluate fracture healing, joint alignment, and the extent of malunion. Comparison with prior imaging may help confirm the malunion.

Treatment Options

• Conservative management: Orthotics, physical therapy, or activity modification to reduce pain and improve function.
• Interventional options: Bracing or casting for support, or surgical correction if malunion causes significant functional impairment.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Regular follow-up with imaging and clinical assessments is recommended to monitor healing and adjust treatment. Long-term management may focus on symptom relief and preventing further joint damage.

Complications

• Chronic pain or arthritis in the subtalar joint.
• Gait abnormalities or increased fall risk.
• Reduced mobility or activity limitations.

Lifestyle & Prevention

• Use proper footwear with arch support to reduce joint stress.
• Avoid high-impact activities that strain the heel during recovery.
• Follow rehabilitation guidelines to optimize healing and alignment.
• Maintain bone health through diet and exercise to support future fracture prevention.

When to Seek Professional Help

Seek care if chronic pain worsens, gait changes, or new swelling occurs. Prompt evaluation is needed if symptoms interfere with daily activities or if signs of infection (e.g., redness, warmth) develop.

Tips for Medical Coders

Document the subsequent encounter status and confirmation of malunion. Include details on prior fracture history, imaging findings, and clinical assessment of healing. Ensure documentation supports the malunion diagnosis to justify the code.
