S92.052K Displaced other extraarticular fracture of left calcaneus, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

This condition involves a displaced fracture of the left calcaneus (heel bone) that occurs outside the joint surfaces, during a subsequent encounter 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 "extraarticular" indicates it does not involve the subtalar or calcaneocuboid joints. Displacement means the bone fragments are misaligned, which may affect stability and healing. The term "subsequent encounter" signifies follow-up care after the initial treatment phase, and "nonunion" indicates the fracture has not healed within the expected timeframe, potentially requiring additional intervention.

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. Nonunion may result from inadequate immobilization, poor blood supply to the bone, infection, or other factors that impede healing.

Risk Factors

• Engaging in high-impact activities or sports.
• Osteoporosis or other bone-weakening conditions.
• Improper footwear or uneven surfaces that increase fall risk.
• Smoking or other lifestyle factors that impair bone healing.
• Prior history of fractures or nonunion.

Symptoms

• Persistent pain in the heel or foot, often worsening with activity.
• Swelling, bruising, or tenderness around the heel that does not resolve.
• Difficulty or inability to bear weight on the affected foot.
• Possible deformity if the fracture is displaced.
• Lack of improvement in symptoms despite prior treatment.

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 its extent. Additional tests, such as bone scans or MRI, may be used to assess blood flow and healing potential. Documentation of nonunion requires evidence of failed healing over time, typically confirmed by imaging.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture.
• Surgical intervention, such as bone grafting, internal fixation, or external fixation, to promote healing.
• Physical therapy to restore strength and mobility.
• Pain management with medications or other modalities.
• Lifestyle modifications to support bone healing, such as smoking cessation.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient factors, and response to treatment. Nonunion may require extended follow-up and additional interventions. Regular imaging and clinical assessments are necessary to monitor healing progress. Long-term outcomes may include persistent pain, reduced mobility, or the need for further surgery.

Complications

• Chronic pain or disability.
• Infection, especially if surgery is performed.
• Arthritis or joint damage due to misalignment.
• Nerve or blood vessel injury.
• Need for additional surgeries or prolonged treatment.

Lifestyle & Prevention

• Wear appropriate footwear and protective gear during high-risk activities.
• Maintain bone health through diet and exercise, including calcium and vitamin D intake.
• Avoid smoking and excessive alcohol, which can impair healing.
• Use caution on uneven surfaces or at heights to reduce fall risk.
• Follow post-injury care instructions to support healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after an injury. Contact a healthcare provider if symptoms persist or worsen despite treatment, or if you notice signs of infection (e.g., fever, redness, drainage). Follow up with your provider as scheduled to monitor healing and address concerns.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture care, with clear evidence of nonunion (e.g., imaging reports, clinical notes). Ensure the code S92.052K is used only when the fracture is confirmed to be nonunion and the encounter is for follow-up of this specific condition. Include details about prior treatments, current symptoms, and any interventions performed during the visit to support accurate coding.
