S99.029S Salter-Harris Type II physeal fracture of unspecified calcaneus, sequela

Name of the Condition

• Salter-Harris Type II physeal fracture of unspecified calcaneus, sequela
• Growth plate fracture of the heel bone (Type II), long-term effects

Summary

This condition represents the long-term consequences (sequela) of a Salter-Harris Type II physeal fracture of the calcaneus (heel bone). It occurs after the initial injury has healed, potentially leading to persistent structural or functional changes. Type II fractures involve a separation of the growth plate with a metaphyseal fragment, and sequelae may include growth disturbances, chronic pain, or altered biomechanics of the foot and ankle.

Causes

The sequela arises from a prior Salter-Harris Type II fracture of the calcaneus, where incomplete healing, malunion, or growth plate disruption during the initial injury leads to lasting effects. The original trauma—such as falls, sports injuries, or accidents—disrupted the growth plate, and subsequent healing processes resulted in residual issues.

Risk Factors

• Age: Children and adolescents, as their growth plates are still developing and more susceptible to injury-related growth disturbances.
• Severity of initial fracture: More severe or displaced fractures increase the risk of sequelae.
• Delayed or inadequate initial treatment: Improper management of the original injury may contribute to long-term complications.

Symptoms

• Chronic pain or discomfort in the heel or ankle area.
• Altered gait or difficulty with weight-bearing activities.
• Visible deformity or uneven growth of the heel bone.
• Reduced range of motion in the foot or ankle.

Diagnosis

Clinical evaluation focuses on assessing persistent symptoms and functional limitations. Imaging, such as X-rays or MRI, may be used to identify residual bone changes, growth plate abnormalities, or joint alignment issues. Comparison with prior injury records helps confirm the link to the original fracture.

Treatment Options

Management depends on the specific sequelae and may include physical therapy to improve mobility, orthotic devices for support, pain management, or surgical intervention for severe deformities. Treatment aims to alleviate symptoms and optimize function.

Prognosis and Follow-Up

Prognosis varies based on the extent of the sequela. Mild cases may have minimal impact, while severe growth disturbances could require ongoing monitoring. Regular follow-up with a healthcare provider ensures timely intervention for complications and helps maintain quality of life.

Complications

• Chronic pain or arthritis in the ankle or subtalar joint.
• Limb length discrepancy or angular deformity due to growth plate damage.
• Reduced mobility or functional limitations in daily activities.

Lifestyle & Prevention

• Avoid high-impact activities that stress the heel until cleared by a provider.
• Use supportive footwear to reduce strain on the foot and ankle.
• Maintain a healthy weight to minimize joint stress.

When to Seek Professional Help

Seek care if chronic pain worsens, mobility declines, or new deformities develop. Prompt evaluation is important to address complications and adjust treatment as needed.

Tips for Medical Coders

This code is used for sequelae of a Salter-Harris Type II physeal fracture of the calcaneus. Document the link to the original injury, the nature of the sequela (e.g., growth disturbance, chronic pain), and any relevant clinical findings to support coding. Ensure the code is not used for acute injuries or initial encounters.
