S59.029D Salter-Harris Type II physeal fracture of lower end of ulna, unspecified arm, subsequent encounter for fracture with routine healing

Name of the Condition

• Salter-Harris Type II physeal fracture of lower end of ulna, unspecified arm, subsequent encounter for fracture with routine healing

Summary

This condition involves a fracture of the growth plate (physeal) at the lower end of the ulna bone, classified as Salter-Harris Type II, with routine healing during a subsequent encounter. It typically affects children and adolescents, where the fracture extends through the physis (growth plate) and into the metaphysis. The injury may result from trauma to the forearm, particularly near the wrist joint. This code is used for follow-up care after initial treatment, indicating the fracture is healing as expected.

Causes

Salter-Harris Type II physeal fractures often occur due to direct impact, such as a fall onto an outstretched hand, or from forceful twisting of the forearm. These injuries are common in activities involving sudden stops or collisions, where the growth plate is weaker than surrounding bone. The subsequent encounter phase reflects ongoing management after the initial injury.

Risk Factors

• Children and adolescents are at higher risk due to the presence of growth plates.
• Participation in contact sports or activities with a high likelihood of falls increases risk.
• Certain genetic or metabolic conditions affecting bone development may also elevate susceptibility.

Symptoms

• Pain and swelling near the wrist or forearm (may be reduced during healing).
• Difficulty moving the wrist or hand (improving with healing).
• Tenderness to touch at the fracture site (diminishing over time).
• Possible bruising around the affected area (fading as healing progresses).

Diagnosis

Physical examination by a healthcare professional to assess pain, swelling, and range of motion during follow-up. Imaging tests, especially X-rays, may be used to confirm routine healing and assess bone alignment. Clinical evaluation focuses on monitoring progress and ensuring no complications.

Treatment Options

Treatment during the subsequent encounter typically involves monitoring healing, ensuring proper immobilization (e.g., cast or brace), and guiding gradual return to activity. Physical therapy may be recommended to restore strength and mobility. Pain management and follow-up imaging are common to confirm continued healing.

Prognosis and Follow-Up

With routine healing, most Salter-Harris Type II fractures of the ulna have a good prognosis. Follow-up care ensures the fracture heals properly and function is restored. Regular assessments by a healthcare provider are important to track progress and address any concerns.

Complications

Complications are rare with routine healing but may include delayed union, growth disturbances, or stiffness. Close monitoring helps detect and manage these issues early.

Lifestyle & Prevention

• Avoid high-risk activities until cleared by a healthcare provider.
• Use protective gear during sports to reduce injury risk.
• Maintain a balanced diet with adequate calcium and vitamin D to support bone health.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility decreases during healing. Contact a healthcare provider if there are signs of infection (e.g., redness, fever) or if the injury does not improve as expected.

Tips for Medical Coders

Use this code for subsequent encounters where the fracture is healing routinely. Document the encounter type (subsequent) and confirm routine healing. Ensure the fracture is classified as Salter-Harris Type II and involves the lower end of the ulna. Do not use this code for initial encounters or complications.
