S99.021K Salter-Harris Type II physeal fracture of right calcaneus, subsequent encounter for fracture with nonunion

Name of the Condition

• Salter-Harris Type II physeal fracture of right calcaneus, subsequent encounter for fracture with nonunion

Summary

This condition involves a Salter-Harris Type II fracture of the growth plate (physis) in the right calcaneus (heel bone), classified as a subsequent encounter for fracture with nonunion. Type II fractures involve a separation of the growth plate with a metaphyseal fragment, and the "nonunion" designation indicates the fracture has failed to heal properly after an initial injury. This typically occurs in children or adolescents due to the developing bone structure and requires evaluation to guide appropriate management for delayed healing.

Causes

Direct trauma or injury to the right heel, such as falls, sports-related impacts, or accidents. Sudden force applied to the foot can disrupt the growth plate and cause the characteristic fracture pattern, which may progress to nonunion if healing is impaired.

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 immobilization or delayed care can contribute to nonunion.

Symptoms

• Persistent pain and swelling localized to the heel area.
• Difficulty bearing weight or walking on the affected foot.
• Limited range of motion in the ankle or foot.
• Visible deformity or instability in severe cases.
• Possible clicking or grinding sensations during movement.

Diagnosis

Physical examination to assess pain, swelling, and function, combined with imaging studies such as X-rays or CT scans to evaluate fracture alignment and healing status. Additional tests may be used to rule out infection or other complications.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a cast or brace, surgical intervention to realign and stabilize the fracture, or bone grafting to stimulate union. Physical therapy is often recommended to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Regular follow-up with imaging is necessary to monitor healing. Long-term outcomes may include persistent pain or functional limitations if healing is incomplete, but most patients achieve satisfactory recovery with appropriate care.

Complications

• Chronic pain or instability in the heel.
• Delayed growth or deformity of the calcaneus.
• Increased risk of arthritis in the surrounding joints.
• Potential need for additional surgeries if nonunion persists.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use proper footwear and protective gear during sports.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Follow rehabilitation guidelines to optimize healing and prevent re-injury.

When to Seek Professional Help

Seek immediate medical attention if pain worsens, swelling increases, or there is new deformity. Contact a healthcare provider if symptoms persist despite treatment or if there are signs of infection, such as redness, warmth, or fever.

Tips for Medical Coders

Document the subsequent encounter status and confirmation of nonunion clearly in the medical record. Ensure the fracture type (Salter-Harris II) and location (right calcaneus) are specified, along with any surgical or therapeutic interventions performed.
