S49.039S Salter-Harris Type III physeal fracture of upper end of humerus, unspecified arm, sequela

Name of the Condition

• Salter-Harris Type III physeal fracture of upper end of humerus, unspecified arm, sequela (ICD-10 Code: S49.039S)

Summary

This code describes a Salter-Harris Type III fracture involving the growth plate (physeal) at the upper end of the humerus, the bone of the upper arm, in an unspecified arm. This type of fracture extends through the growth plate and into the epiphysis (the end of the bone), typically occurring in children and adolescents due to the relative weakness of the physis during development. The "sequela" modifier indicates the condition represents a residual effect or complication following the acute fracture, such as chronic pain, deformity, or functional impairment.

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

• Chronic pain or discomfort at the shoulder or upper arm
• Limited range of motion or stiffness
• Visible deformity or malalignment
• Difficulty with daily activities involving arm use

Diagnosis

Diagnosis relies on a physical examination to assess residual pain, swelling, and range of motion, combined with imaging studies like X-rays to visualize the fracture site and confirm healing status. A detailed patient history, including the original injury and subsequent recovery, is also important.

Treatment Options

Treatment focuses on managing residual symptoms and may include physical therapy to improve strength and mobility, pain management, or surgical intervention if deformity or functional impairment is significant. The approach depends on the severity of the sequela and the patient’s functional needs.

Prognosis and Follow-Up

Prognosis varies based on the initial injury severity and treatment. Most patients experience some residual effects, but many achieve good functional outcomes with appropriate management. Regular follow-up is important to monitor for complications and adjust treatment as needed.

Complications

• Chronic pain or arthritis
• Growth disturbances or limb length discrepancy
• Reduced range of motion or stiffness
• Functional limitations in daily activities

Lifestyle & Prevention

• Engage in regular physical therapy to maintain mobility and strength.
• Use protective equipment during sports or high-risk activities.
• Follow post-injury guidelines to minimize long-term effects.

When to Seek Professional Help

Seek medical attention if residual symptoms worsen, new pain or deformity develops, or functional limitations impact daily life. Early evaluation can help address complications and optimize recovery.

Tips for Medical Coders

This code is used for sequela of a Salter-Harris Type III physeal fracture of the upper humerus. Document the residual effects (e.g., chronic pain, deformity) and confirm the fracture history to support coding. Ensure the "sequela" modifier is appropriate for long-term complications following the acute injury.
