S49.002S Unspecified physeal fracture of upper end of humerus, left arm, sequela

Name of the Condition

• Unspecified Physeal Fracture of Upper End of Humerus, Left Arm, Sequela (ICD-10 Code: S49.002S)

Summary

This code describes a fracture involving the growth plate (physeal) at the upper end of the left humerus, with residual effects or complications following the healing of the initial injury. Physeal fractures occur in the area of developing bone and are more common in children and adolescents. The "sequela" designation indicates the condition is a late effect of the prior fracture, such as chronic pain, deformity, or functional impairment.

Causes

Physeal fractures typically result from trauma, such as falls, sports injuries, or direct blows to the arm. They can also occur due to sudden forceful movements or repetitive stress in younger individuals with open growth plates. The sequela arises from incomplete healing, malunion, or persistent damage to the growth plate.

Risk Factors

• Participation in high-impact activities (e.g., contact sports, gymnastics)
• Age (common in children and adolescents with active growth plates)
• Prior injuries to the same area
• Insufficient protective gear during physical activities

Symptoms

• Chronic pain, swelling, or tenderness at the upper end of the left humerus
• Limited range of motion in the shoulder or elbow
• Visible deformity or limb length discrepancy
• Difficulty bearing weight or using the arm

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and mobility, combined with imaging studies like X-rays to evaluate residual bone changes or growth plate abnormalities. A detailed patient history helps determine the mechanism of the original injury and the timeline of symptoms.

Treatment Options

Treatment focuses on managing symptoms and addressing functional impairment. Options may include physical therapy to improve range of motion, pain management, or surgical intervention for severe deformity or growth disturbances. The approach depends on the extent of residual damage and the patient’s functional needs.

Prognosis and Follow-Up

Prognosis varies based on the severity of the sequela and the patient’s age. Children with growth plate injuries may experience long-term growth issues, while adults may have persistent pain or stiffness. Regular follow-up with imaging and functional assessments is recommended to monitor for complications.

Complications

• Chronic pain or stiffness
• Limb length discrepancy or deformity
• Growth plate arrest leading to uneven bone development
• Reduced shoulder or elbow function

Lifestyle & Prevention

• Use protective gear during high-impact activities
• Avoid repetitive stress on the arm in children with open growth plates
• Engage in age-appropriate physical activity to support bone health
• Follow post-injury rehabilitation guidelines to minimize long-term effects

When to Seek Professional Help

Seek medical attention if symptoms worsen, new deformity develops, or there is significant pain or functional limitation. Early evaluation can help address complications and prevent further damage.

Tips for Medical Coders

This code is used for the sequela of an unspecified physeal fracture of the upper end of the left humerus. Document the residual effects (e.g., chronic pain, deformity) and confirm the fracture occurred in the left arm. Ensure the encounter is for the late effect, not the initial injury or healing phase.
