S49.041S Salter-Harris Type IV physeal fracture of upper end of humerus, right arm, sequela

Name of the Condition

• Salter-Harris Type IV physeal fracture of upper end of humerus, right arm, sequela (ICD-10 Code: S49.041S)

Summary

This code describes a Salter-Harris Type IV fracture of the growth plate (physeal) at the upper end of the right humerus, with residual effects (sequela) following the injury. Type IV fractures involve a break through the metaphysis, across the growth plate, and into the epiphysis, often affecting joint alignment. The "sequela" modifier indicates ongoing consequences after the acute phase, such as chronic pain, deformity, or functional impairment.

Causes

The initial fracture typically results from trauma, such as a fall onto an outstretched hand or a direct blow to the shoulder. These injuries often occur during sports, play, or accidents involving forceful arm movement. The sequela arise from incomplete healing, malunion, or long-term joint damage.

Risk Factors

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

Symptoms

• Chronic pain or discomfort in the shoulder or upper arm
• Reduced range of motion or stiffness
• Visible deformity or limb length discrepancy
• Functional limitations, such as difficulty lifting or rotating the arm

Diagnosis

Diagnosis involves a physical examination to assess residual pain, deformity, and functional impairment, combined with imaging studies like X-rays or MRI to evaluate healing and joint alignment. A detailed patient history, including the original injury and treatment, is essential to confirm the sequela.

Treatment Options

• Rehabilitation: Physical therapy to improve strength and range of motion
• Pain management: Medications or injections for chronic discomfort
• Surgical intervention: Corrective procedures for severe deformity or joint issues
• Assistive devices: Braces or supports to stabilize the arm during activity

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and the effectiveness of treatment. Some patients may experience long-term functional limitations, while others recover with minimal impact. Regular follow-up is necessary to monitor healing and address complications.

Complications

• Chronic pain or arthritis
• Growth disturbances or limb length discrepancy
• Joint instability or deformity
• Reduced mobility or strength

Lifestyle & Prevention

• Avoid high-impact activities that risk re-injury
• Use protective gear during sports or physical activities
• Engage in regular, low-impact exercise to maintain joint health
• Follow post-treatment guidelines to support recovery

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or deformity develops, or functional limitations interfere with daily activities. Prompt evaluation can help address complications early.

Tips for Medical Coders

This code is used for sequela (residual effects) of a Salter-Harris Type IV physeal fracture of the upper humerus, right arm. Document the nature of the sequela (e.g., chronic pain, deformity) and confirm the original injury and treatment history. Ensure the code aligns with the patient’s current clinical status and follow-up care.
