S59.021S Salter-Harris Type II physeal fracture of lower end of ulna, right arm, sequela

Name of the Condition

• Salter-Harris Type II physeal fracture of lower end of ulna, right arm, sequela

Summary

This condition represents a Salter-Harris Type II physeal fracture of the lower end of the ulna in the right arm, classified as a sequela. Salter-Harris Type II fractures involve a break through the growth plate (physis) that extends into the metaphysis, typically affecting children and adolescents. The "sequela" modifier indicates the condition is a residual effect following the healing of the initial injury, with ongoing consequences or complications.

Causes

Salter-Harris Type II physeal fractures of the ulna often result from trauma, such as a fall onto an outstretched hand, a direct blow to the forearm, or forceful twisting of the wrist. These injuries are common in activities involving sudden impacts or collisions, where the growth plate—being weaker than surrounding bone—sustains damage.

Risk Factors

• Children and adolescents, due to the presence of growth plates.
• Participation in contact sports or activities with a high risk of falls.
• Pre-existing conditions affecting bone strength or development.

Symptoms

• Persistent pain or discomfort near the wrist or forearm.
• Limited range of motion in the wrist or hand.
• Visible deformity or malalignment of the affected area.
• Possible functional impairment related to the residual effects of the fracture.

Diagnosis

Diagnosis involves a thorough clinical evaluation, including assessment of the patient’s history of the initial injury and current symptoms. Physical examination focuses on identifying residual deformity, tenderness, or functional limitations. Imaging studies, such as X-rays or CT scans, may be used to assess the extent of the sequela and any associated complications.

Treatment Options

Treatment depends on the severity of the sequela and may include physical therapy to improve mobility and strength, pain management, or surgical intervention if significant deformity or functional impairment is present. Orthopedic consultation is often recommended to determine the most appropriate management plan.

Prognosis and Follow-Up

Prognosis varies based on the initial injury’s severity and the effectiveness of prior treatment. Regular follow-up with a healthcare provider is essential to monitor for long-term complications, such as growth disturbances or chronic pain. Rehabilitation and activity modifications may be necessary to optimize recovery.

Complications

Potential complications include chronic pain, limited joint mobility, growth plate disturbances leading to limb length discrepancies, or arthritis in the affected joint. Early intervention and ongoing monitoring can help mitigate these risks.

Lifestyle & Prevention

• Avoid high-impact activities that may exacerbate residual symptoms.
• Engage in targeted physical therapy to maintain or improve function.
• Use protective equipment during sports or activities to prevent re-injury.
• Follow healthcare provider recommendations for activity restrictions or modifications.

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or deformity develops, or functional limitations increase. Prompt evaluation is important to address complications or adjust treatment as needed.

Tips for Medical Coders

This code (S59.021S) is used to document a sequela of a Salter-Harris Type II physeal fracture of the lower end of the ulna in the right arm. Coders should ensure the documentation clearly indicates the condition is a residual effect of a prior fracture, with no active healing or acute injury. The "sequela" modifier is appropriate when the condition represents the long-term consequences of the initial injury.
