S49.022 Salter-Harris Type II physeal fracture of upper end of humerus, left arm

Name of the Condition

• Salter-Harris Type II physeal fracture of upper end of humerus, left arm (ICD-10 Code: S49.022)

Summary

This code describes a Salter-Harris Type II fracture involving the growth plate (physeal) at the upper end of the left humerus. This type of fracture occurs when the growth plate and a portion of the metaphysis (the area adjacent to the growth plate) separate from the rest of the bone, typically in children and adolescents due to the relative weakness of the physis during development.

Causes

Trauma, such as a fall onto an outstretched hand or a direct blow to the shoulder, is the primary cause. These injuries often 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

• Pain and swelling at the shoulder or upper arm
• Limited range of motion
• Visible deformity in severe cases
• Difficulty moving the arm

Diagnosis

Diagnosis relies on a physical examination to assess pain, swelling, and range of motion, combined with imaging studies like X-rays to visualize the fracture and confirm its location at the growth plate. A detailed patient history, including the mechanism of injury, is also important.

Treatment Options

• Immobilization: A sling or cast may be used to stabilize the arm and allow healing.
• Pain management: Medications or other interventions to reduce discomfort.
• Surgical intervention: May be necessary for severe or displaced fractures to realign the bone.
• Physical therapy: Recommended during recovery to restore strength and mobility.

Prognosis and Follow-Up

Most Salter-Harris Type II fractures heal well with appropriate treatment, especially when diagnosed early. Follow-up care, including monitoring for growth disturbances or deformity, is important, particularly in children with open growth plates. Long-term outcomes depend on the severity of the injury and adherence to treatment plans.

Complications

• Growth plate damage leading to limb length discrepancies or angular deformities
• Stiffness or reduced range of motion in the shoulder or arm
• Chronic pain in rare cases
• Infection (if surgical intervention is required)

Lifestyle & Prevention

• Use protective gear during sports or activities with a risk of falls.
• Ensure proper supervision of children during play to minimize accident risks.
• Maintain bone health through adequate nutrition (e.g., calcium and vitamin D) to support healing.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible deformity, inability to move the arm, or signs of infection (e.g., redness, swelling, fever) after an injury.

Tips for Medical Coders

This code specifies a Salter-Harris Type II physeal fracture of the upper end of the humerus in the left arm. Accurate documentation should include the fracture type, location, and laterality. Ensure the medical record supports the diagnosis and treatment provided to justify the code assignment.
