S92.062K Displaced intraarticular fracture of left calcaneus, subsequent encounter for fracture with nonunion

Name of the Condition

• Displaced intraarticular fracture of left calcaneus, subsequent encounter for fracture with nonunion

Summary

A displaced intraarticular fracture of the left calcaneus is a break in the left heel bone where the bone fragments are misaligned and the fracture extends into the joint space. This subsequent encounter code applies when the patient is receiving active treatment for the fracture, and the fracture has failed to heal (nonunion) after a reasonable healing period. The condition can disrupt joint alignment and function, leading to persistent pain and impaired mobility.

Causes

High-impact trauma, such as falls from a height or motor vehicle accidents, commonly causes this fracture. Direct force to the heel, including sports-related injuries or workplace accidents, can also result in this condition. Nonunion may develop due to inadequate immobilization, poor blood supply to the bone, infection, or other factors that impede healing.

Risk Factors

• Participation in high-impact sports or activities.
• Occupations involving heights or fall risks.
• Osteoporosis or other bone-weakening conditions.
• Uneven surfaces or improper footwear increasing fall risk.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent severe heel pain, especially with weight-bearing.
• Swelling and bruising around the ankle and heel.
• Difficulty or inability to bear weight on the affected foot.
• Possible deformity of the heel.
• Lack of improvement in symptoms over time, indicating nonunion.

Diagnosis

Physical examination to assess pain, swelling, deformity, and functional impairment. Imaging tests, such as X-rays, CT scans, or MRI, to confirm the fracture and evaluate for nonunion (e.g., visible gap at the fracture site, lack of callus formation). Additional tests may assess blood flow or infection if needed.

Treatment Options

• Conservative management: Prolonged immobilization, bone stimulation therapies, or orthotics to support healing.
• Surgery: Internal fixation, bone grafting, or joint reconstruction to promote union and restore function.
• Rehabilitation: Physical therapy to improve strength and mobility after treatment.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient factors, and treatment response. Nonunion may require extended treatment and rehabilitation. Regular follow-up with imaging is necessary to monitor healing progress. Long-term outcomes may include persistent pain or arthritis if joint alignment is not fully restored.

Complications

• Chronic pain or arthritis in the subtalar joint.
• Persistent nonunion requiring additional surgery.
• Nerve damage or vascular impairment.
• Difficulty with weight-bearing or mobility.

Lifestyle & Prevention

• Use proper footwear and avoid uneven surfaces to reduce fall risk.
• Maintain bone health through diet and exercise (e.g., calcium, vitamin D).
• Follow post-injury care instructions to support healing.
• Avoid high-impact activities until cleared by a healthcare provider.

When to Seek Professional Help

Seek immediate care if you experience severe heel pain after trauma, inability to bear weight, or signs of infection (e.g., fever, increased swelling, redness). Follow up with a provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

This code is used for a subsequent encounter for a displaced intraarticular fracture of the left calcaneus with nonunion. Document the fracture’s status (nonunion) and the encounter type (subsequent) to support coding. Ensure clinical documentation specifies the fracture’s location (left calcaneus), displacement, intraarticular involvement, and nonunion to justify the code.
