S92.055K Nondisplaced other extraarticular fracture of left calcaneus, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

This condition refers to a nondisplaced fracture of the left calcaneus (heel bone) that occurs outside the joint surfaces, with subsequent encounter indicating follow-up care for a fracture that has failed to heal (nonunion). The fracture is classified as "other" to denote a specific type not covered by more detailed subcategories, and it is extraarticular, meaning it does not involve the subtalar or calcaneocuboid joints. Nondisplacement means the bone fragments remain in their normal alignment, but nonunion indicates the fracture has not progressed through the normal healing stages. This stage of care focuses on addressing the nonunion and supporting further healing.

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.
• Poor blood supply to the fracture site.
• Inadequate initial immobilization or treatment.

Symptoms

• Persistent pain in the heel or foot, often localized to the fracture site.
• Swelling or tenderness that does not improve over time.
• Difficulty or inability to bear weight on the affected foot.
• Possible instability or deformity if the fracture has shifted.

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 healing progress. Assessment of the fracture site to determine if nonunion is present, often requiring comparison to prior imaging.

Treatment Options

• Surgical intervention, such as bone grafting or internal fixation, to promote healing.
• Immobilization with a cast or brace to stabilize the fracture.
• Pain management and anti-inflammatory medications.
• Physical therapy to restore strength and mobility once healing is underway.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Follow-up care is essential to monitor healing and adjust treatment as needed. Regular imaging may be required to assess progress.

Complications

• Chronic pain or disability.
• Infection, particularly if surgical intervention is performed.
• Delayed or incomplete healing.
• Long-term joint damage or arthritis.

Lifestyle & Prevention

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

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or weight-bearing becomes more difficult. Prompt evaluation is necessary if signs of infection (e.g., fever, redness, drainage) occur.

Tips for Medical Coders

Document the fracture type (nondisplaced, extraarticular), laterality (left), and the presence of nonunion. Include details of the encounter (subsequent) and any treatment provided. Ensure documentation supports the nonunion diagnosis to justify the code.
