S49.141S Salter-Harris Type IV physeal fracture of lower end of humerus, right arm, sequela

Name of the Condition

• Salter-Harris Type IV physeal fracture of lower end of humerus, right arm, sequela (ICD-10 Code: S49.141S)

Summary

This code describes a Salter-Harris Type IV fracture involving the growth plate (physeal) at the lower end of the right humerus, classified as a sequela. Type IV fractures extend through the metaphysis, physis, and epiphysis, potentially disrupting both growth and joint alignment. The sequela designation indicates residual effects following the acute phase of healing, such as chronic pain, deformity, or functional limitations. These injuries are most common in children and adolescents due to the relative weakness of the growth plate during development.

Causes

Trauma is the primary cause, typically resulting from a fall onto an outstretched hand, a direct blow to the elbow, or forceful arm movement. High-impact activities, such as sports or accidents, can generate the necessary force to cause this fracture type. The sequela arises from incomplete healing or complications during the recovery process.

Risk Factors

• Age (most common in children and adolescents with open growth plates)
• Participation in high-impact or contact sports
• Prior growth plate injuries or developmental abnormalities
• Activities involving repetitive stress on the elbow

Symptoms

• Chronic pain or discomfort in the elbow or lower arm
• Tenderness over the distal humeral growth plate
• Limited range of motion in the affected arm
• Possible visible deformity or malalignment
• Difficulty with daily activities requiring arm use

Diagnosis

Diagnosis relies on clinical evaluation and imaging studies, such as X-rays or MRI, to assess residual bone or joint abnormalities. The sequela status is determined by the presence of long-term effects following the fracture, including persistent symptoms or structural changes. Documentation should reflect the ongoing nature of the condition and its impact on function.

Treatment Options

Treatment focuses on managing symptoms and addressing functional limitations. Options may include physical therapy to improve range of motion, pain management, or surgical intervention for severe deformity. The approach is tailored to the specific residual effects and patient needs.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and the effectiveness of prior treatment. Some patients may experience long-term limitations, while others recover with minimal impact. Regular follow-up is recommended to monitor for complications and adjust management as needed.

Complications

• Chronic pain or stiffness
• Growth disturbances or limb length discrepancy
• Joint instability or arthritis
• Persistent deformity affecting function

Lifestyle & Prevention

• Avoid high-impact activities that stress the elbow
• Use protective gear during sports or recreational activities
• Engage in exercises to maintain strength and flexibility
• Follow post-injury care guidelines to minimize long-term effects

When to Seek Professional Help

Seek medical attention if symptoms worsen, new deformity develops, or daily activities become significantly impaired. Prompt evaluation is important to address complications and optimize outcomes.

Tips for Medical Coders

This code is used for the sequela of a Salter-Harris Type IV physeal fracture of the lower humerus, right arm. Documentation should clearly indicate the residual effects, such as chronic pain, deformity, or functional limitations, and their relationship to the prior fracture. The sequela status requires evidence of a condition persisting beyond the acute healing phase. Ensure the code aligns with the patient’s current clinical status and treatment plan.
