S92.055P Nondisplaced other extraarticular fracture of left calcaneus, subsequent encounter for fracture with malunion

Name of the Condition

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

Summary

This condition refers to a fracture of the left calcaneus (heel bone) that is extraarticular (not involving joint surfaces) and nondisplaced, with malunion (healing in an abnormal position) during a subsequent encounter for fracture care. The fracture remains outside the subtalar or calcaneocuboid joints, and the bone fragments are not displaced but have healed improperly. It typically results from trauma and may affect weight-bearing ability depending on the malunion's severity and location.

Causes

High-impact trauma, such as falls from a height or automobile accidents. Direct force to the heel, often seen in sports injuries or workplace accidents.

Risk Factors

• Engaging in high-impact activities or sports.
• Osteoporosis or other bone-weakening conditions.
• Improper footwear or uneven surfaces that increase fall risk.

Symptoms

• Persistent pain in the heel or foot, especially during weight-bearing.
• Swelling, bruising, or tenderness around the heel.
• Difficulty or inability to bear weight on the affected foot.
• Possible deformity or altered gait due to malunion.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays or CT scans, to confirm the fracture and evaluate malunion. Comparison with prior imaging to assess healing progression.

Treatment Options

• Pain management with medications or physical therapy.
• Orthotic devices or braces to support the foot and improve alignment.
• Surgical intervention (e.g., osteotomy) if malunion causes significant functional impairment.
• Rehabilitation to restore strength and mobility.

Prognosis and Follow-Up

Prognosis depends on the malunion's severity and response to treatment. Follow-up care may include regular imaging to monitor healing and functional assessments to guide rehabilitation. Long-term outcomes can vary, with some patients experiencing persistent pain or mobility limitations.

Complications

• Chronic pain or arthritis due to altered joint mechanics.
• Reduced mobility or gait abnormalities.
• Increased risk of future fractures in the affected area.

Lifestyle & Prevention

• Wear supportive footwear and use protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid uneven surfaces or high-impact activities that increase fall risk.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility declines significantly. Prompt evaluation is needed if new deformity or signs of infection (e.g., redness, fever) develop.

Tips for Medical Coders

Document the presence of malunion and specify the encounter as subsequent for fracture care. Include details on imaging findings, treatment provided, and any functional limitations to support code assignment. Ensure documentation aligns with the clinical status of the fracture and healing progress.
