S92.064K Nondisplaced intraarticular fracture of right calcaneus, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

A nondisplaced intraarticular fracture of the right calcaneus is a break in the right heel bone where the fracture extends into the joint space but the bone fragments remain in their normal alignment. This injury affects the subtalar joint and is now in a subsequent encounter phase with nonunion, meaning the fracture has not healed as expected. Symptoms typically include persistent pain, swelling, and limited mobility, as the fracture site remains unstable and requires further intervention.

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. The subsequent encounter with nonunion indicates the fracture has failed to heal during the expected timeframe, potentially due to inadequate immobilization, poor blood supply, or underlying health conditions.

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 poor nutrition, which can impair 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 stiffness or limited range of motion in the subtalar joint.
• Sensation of instability in the heel.

Diagnosis

Physical examination to assess pain, swelling, and deformity. Imaging tests, such as X-rays, CT scans, or MRI, to confirm the fracture and evaluate joint involvement, alignment, and signs of nonunion. Additional tests may be ordered to identify underlying factors contributing to delayed healing.

Treatment Options

• Surgical intervention: Internal fixation, bone grafting, or other procedures to promote healing.
• Immobilization: Extended use of a cast or boot to stabilize the fracture.
• Physical therapy: To restore mobility and strength once healing progresses.
• Pain management: Medications or other therapies to control discomfort.

Prognosis and Follow-Up

Prognosis depends on the success of treatment and the underlying cause of nonunion. Regular follow-up with imaging is necessary to monitor healing. Full recovery may take several months, and some patients may experience long-term joint stiffness or arthritis.

Complications

• Chronic pain or instability in the heel.
• Development of arthritis in the subtalar joint.
• Need for additional surgeries if healing does not occur.
• Potential for permanent mobility limitations.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Use proper footwear and safety equipment during activities with fall risks.
• Follow post-treatment instructions carefully to optimize healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to bear weight, or if symptoms worsen after initial treatment. Contact your provider if you notice signs of infection, such as redness, warmth, or drainage from the injury site.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with nonunion, ensuring clear notation of the fracture's failure to heal. Include details on prior treatments, imaging results, and any contributing factors to support the nonunion diagnosis. Code S92.064K is specific to the right calcaneus and requires confirmation of the nonunion status.
