S92.065K Nondisplaced intraarticular fracture of left calcaneus, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

A nondisplaced intraarticular fracture of the left calcaneus with nonunion is a break in the left heel bone where the fracture extends into the joint space, the bone fragments remain aligned, and healing has not occurred by the time of the subsequent encounter. This condition involves the subtalar joint and may cause persistent pain, swelling, and impaired foot function due to the failure of the fracture to unite.

Causes

High-impact trauma, such as falls from a height or motor vehicle accidents, is a common cause. Direct force to the heel, often seen in sports injuries or workplace accidents, can also result in this fracture. 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.
• Previous heel injuries or surgeries.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent 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.
• Limited range of motion in the subtalar joint.

Diagnosis

Physical examination to assess pain, swelling, deformity, and joint mobility. Imaging tests, such as X-rays, CT scans, or MRI, to confirm the fracture, evaluate joint involvement, and assess for nonunion (e.g., visible gap or sclerosis at the fracture site).

Treatment Options

• Conservative management: Prolonged immobilization, bone stimulation therapies, or orthotic devices to support healing.
• Surgical intervention: Bone grafting, internal fixation, or joint fusion to promote union or stabilize the joint.
• Pain management: Medications or physical therapy to address discomfort and improve function.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Follow-up imaging and clinical assessments are typically required to monitor healing progress. Long-term outcomes may include persistent pain or reduced mobility if union is not achieved.

Complications

• Chronic pain or arthritis in the subtalar joint.
• Permanent disability or reduced mobility.
• Infection (if surgical intervention is performed).
• Need for additional surgeries if initial treatment fails.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use proper footwear and orthotics to support the foot.
• Maintain bone health through diet and exercise (if appropriate).
• Follow post-treatment guidelines to optimize healing.

When to Seek Professional Help

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

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with nonunion. Include details on the fracture’s alignment, joint involvement, and evidence of nonunion (e.g., imaging findings). Ensure documentation supports the use of code S92.065K by confirming the fracture is nondisplaced, intraarticular, and associated with nonunion at the time of the encounter.
