S49.049S Salter-Harris Type IV physeal fracture of upper end of humerus, unspecified arm, sequela

Name of the Condition

• Salter-Harris Type IV physeal fracture of upper end of humerus, unspecified arm, sequela (ICD-10 Code: S49.049S)

Summary

This code describes a Salter-Harris Type IV fracture involving the growth plate (physeal) at the upper end of the humerus, unspecified arm, with sequela. This fracture type extends through the metaphysis, physis, and epiphysis, often involving joint structures. It is most common in children and adolescents due to the relative weakness of the growth plate during development. The "sequela" modifier indicates the condition represents residual effects following the acute injury and healing phase.

Causes

Trauma, such as a fall onto an outstretched hand or a direct blow to the shoulder, is the primary cause. These injuries may occur during sports, play, or accidents involving forceful arm movement.

Risk Factors

• Age (most common in children and adolescents with open growth plates)
• Participation in high-impact sports or activities
• Prior growth plate injuries

Symptoms

• Chronic pain or discomfort at the shoulder or upper arm
• Limited range of motion
• Visible deformity in severe cases
• Difficulty moving the arm
• Possible joint instability

Diagnosis

Diagnosis relies on a physical examination to assess pain, swelling, and range of motion, combined with imaging studies like X-rays to visualize residual effects of the fracture. A detailed patient history, including the mechanism of injury and prior treatment, is also important.

Treatment Options

Treatment focuses on managing residual symptoms and may include physical therapy to improve range of motion and strength, pain management, and monitoring for long-term complications. Surgical intervention may be considered for severe deformities or functional impairment.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and the effectiveness of treatment. Regular follow-up is important to monitor for complications such as growth disturbances or joint issues. Long-term outcomes may vary based on individual factors.

Complications

• Growth plate disturbances leading to limb length discrepancy
• Joint stiffness or arthritis
• Chronic pain
• Functional limitations

Lifestyle & Prevention

• Avoid high-impact activities that risk reinjury
• Use protective gear during sports
• Maintain regular follow-up with a healthcare provider
• Engage in prescribed physical therapy to preserve mobility

When to Seek Professional Help

Seek medical attention if experiencing increasing pain, new deformity, or difficulty with arm movement, as these may indicate complications requiring intervention.

Tips for Medical Coders

This code is used for the sequela of a Salter-Harris Type IV physeal fracture of the upper humerus, unspecified arm. Documentation should specify residual effects and confirm the fracture type, location, and sequela status. Ensure the encounter aligns with the "sequela" modifier to accurately reflect the condition.
