S42.113B Displaced fracture of body of scapula, unspecified shoulder, initial encounter for open fracture

Name of the Condition

• Displaced fracture of body of scapula, unspecified shoulder, initial encounter for open fracture

Summary

A displaced fracture of the body of the scapula involves a break in the main, flat portion of the shoulder blade bone, with the fractured fragments shifted out of their normal alignment. This condition affects the shoulder (unspecified side) and is classified as an open fracture, meaning the bone has pierced the skin or the fracture site is exposed to the external environment. It typically results from significant trauma and requires prompt medical attention to manage pain, prevent infection, and restore function.

Causes

Traumatic injury is the primary cause, often resulting from high-impact events such as motor vehicle accidents, falls from height, or direct forceful blows to the shoulder. Sports-related collisions or crush injuries may also lead to this type of fracture. Open fractures occur when the force of the injury is severe enough to break the skin or expose the fracture site.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, which may increase susceptibility to fractures from minor trauma.
• Previous shoulder or upper arm injuries that affect bone integrity.
• High-velocity trauma, such as motor vehicle collisions or industrial accidents.

Symptoms

• Intense pain in the shoulder or upper back, worsening with movement.
• Swelling, bruising, or tenderness over the shoulder blade.
• Limited range of motion in the shoulder joint.
• Difficulty lifting or rotating the arm.
• Visible wound or exposed bone at the fracture site (indicating an open fracture).
• Possible bleeding or drainage from the open wound.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and visible wounds. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture, evaluate displacement, and assess for open fracture characteristics. The open nature of the fracture is determined by examining the wound and confirming bone exposure or communication with the fracture site.

Treatment Options

Treatment focuses on stabilizing the fracture, preventing infection, and promoting healing. This may include wound cleaning and debridement for open fractures, immobilization with a sling or brace, pain management, and antibiotics to reduce infection risk. Surgical intervention may be necessary for severe displacement or unstable fractures. Physical therapy is often recommended during recovery to restore mobility and strength.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and the absence of complications. Most patients recover with proper care, though open fractures carry a higher risk of infection. Follow-up appointments are essential to monitor healing, assess for complications, and adjust treatment as needed. Full recovery may take several months, with gradual return to normal activities.

Complications

• Infection at the fracture site or wound.
• Delayed healing or nonunion of the fracture.
• Nerve or blood vessel damage near the shoulder.
• Chronic pain or reduced shoulder function.
• Post-traumatic arthritis in the shoulder joint.

Lifestyle & Prevention

• Use protective gear during contact sports or high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if at risk (e.g., older adults).
• Seek prompt medical care for injuries to reduce complication risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe shoulder pain, visible bone or wound at the injury site, or signs of infection (e.g., fever, increased redness, drainage). Delayed care for open fractures increases infection risk and may worsen outcomes.

Tips for Medical Coders

This code (S42.113B) is specific to a displaced fracture of the scapula body with an open fracture, initial encounter. Documentation must confirm the fracture type (displaced), location (body of scapula, unspecified shoulder), and the open nature of the fracture. Ensure the encounter is classified as "initial" and that the fracture is not associated with other injuries unless separately documented.
