S99.039S Salter-Harris Type III physeal fracture of unspecified calcaneus, sequela

Name of the Condition

• Salter-Harris Type III physeal fracture of unspecified calcaneus, sequela
• Growth plate fracture of the heel bone (Type III), sequela

Summary

This condition represents a Salter-Harris Type III physeal fracture of the calcaneus (heel bone) in the sequela phase. It involves a fracture that extends through the growth plate (physis) and into the epiphysis, with residual effects following the healing period. Sequela indicates the condition is a late effect or complication of the initial injury, requiring evaluation of long-term functional or structural changes.

Causes

The sequela arises from a prior Salter-Harris Type III fracture of the calcaneus, where incomplete healing, malunion, or persistent growth plate disruption leads to chronic symptoms or structural abnormalities. The original injury typically resulted from direct trauma to the heel, such as falls or sports-related impacts.

Risk Factors

• Age: Children and adolescents, as their growth plates are still developing and more susceptible to injury.
• High-impact activities: Participation in sports like running, jumping, or contact sports.
• Previous injuries: Prior damage to the heel or surrounding structures may increase vulnerability.
• Inadequate initial treatment: Improper management of the original fracture can contribute to sequela development.

Symptoms

• Chronic pain or discomfort in the heel area.
• Limited range of motion in the ankle or foot.
• Visible deformity or growth disturbance of the calcaneus.
• Difficulty bearing weight or walking on the affected foot.
• Possible joint stiffness or instability.

Diagnosis

Clinical evaluation focuses on assessing residual functional impairment and structural changes. Imaging, such as X-rays or MRI, may be used to evaluate healing, malunion, or growth plate abnormalities. The diagnosis is confirmed by correlating the patient’s history of a prior Salter-Harris Type III fracture with current symptoms and findings.

Treatment Options

Management depends on the severity of residual effects. Options may include physical therapy to improve mobility, orthotic devices for support, or surgical intervention to correct deformities or stabilize the growth plate. Treatment aims to alleviate symptoms and restore function.

Prognosis and Follow-Up

Prognosis varies based on the extent of residual damage. Regular follow-up is essential to monitor growth, joint function, and potential long-term complications. Early intervention can improve outcomes, but some patients may experience persistent limitations.

Complications

• Chronic pain or arthritis in the affected joint.
• Growth disturbances or limb length discrepancy.
• Reduced mobility or functional impairment.
• Increased risk of future fractures in the area.

Lifestyle & Prevention

• Avoid high-impact activities that stress the heel until cleared by a healthcare provider.
• Use appropriate footwear and protective gear during sports.
• Maintain a healthy weight to reduce stress on the foot.
• Follow rehabilitation guidelines to optimize recovery.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or deformity develops, or there is difficulty with daily activities. Prompt evaluation is important for managing complications or adjusting treatment.

Tips for Medical Coders

This code is used for the sequela of a Salter-Harris Type III physeal fracture of the calcaneus. Documentation should specify the residual effects (e.g., chronic pain, deformity) and confirm the prior fracture history. Ensure the code aligns with the patient’s current clinical status and treatment phase.
