S42.152A Displaced fracture of neck of scapula, left shoulder, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of neck of scapula, left shoulder, initial encounter for closed fracture

Summary

A displaced fracture of the neck of the scapula, left shoulder, involves a break in the narrow portion of the shoulder blade bone that connects to the shoulder joint, with the bone fragments shifted out of their normal alignment. This condition affects the left shoulder and is classified as an initial encounter for a closed fracture, meaning the skin is intact and the injury is being addressed for the first time. The scapula's neck region is critical for shoulder stability and movement, and displacement can affect joint function.

Causes

Traumatic injury is the primary cause of this fracture. Common mechanisms include falls onto the shoulder, motor vehicle accidents, or direct blows to the shoulder area. High-impact events, such as sports collisions or forceful impacts, may also result in a displaced fracture of the scapular neck. The force required to displace the bone fragments typically indicates significant trauma.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other bone-weakening conditions that reduce bone density.
• Advanced age, which may increase susceptibility to fractures from minor trauma.
• Previous shoulder or upper arm injuries that compromise bone integrity.

Symptoms

• Pain in the shoulder or upper back, especially with movement.
• Swelling, bruising, or tenderness over the shoulder blade.
• Limited range of motion in the shoulder joint.
• Difficulty lifting or rotating the arm.
• In severe cases, visible deformity or instability.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays or CT scans, are typically used to confirm the fracture and evaluate displacement. The closed nature of the fracture is determined by examining the skin for intactness, and the initial encounter status is established by documenting the first treatment episode for the injury.

Treatment Options

Treatment depends on the severity of displacement and patient factors. Non-displaced or minimally displaced fractures may be managed with immobilization (e.g., sling) and pain control. Displaced fractures may require surgical intervention to realign and stabilize the bone, followed by rehabilitation to restore function. Physical therapy is often recommended to improve mobility and strength.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though recovery time varies. Most patients regain full or near-full shoulder function, but stiffness or residual pain may occur. Follow-up appointments monitor healing, assess range of motion, and adjust treatment plans as needed. Rehabilitation is crucial for optimal recovery.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), chronic pain, or shoulder instability. Nerve or vascular injury near the fracture site is rare but possible. Infection risk is low for closed fractures but may increase with surgical intervention.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Strengthen shoulder and upper back muscles to support the joint. Use protective gear during contact sports. Maintain bone health through adequate calcium and vitamin D intake, especially for those with osteoporosis.

When to Seek Professional Help

Seek immediate care for severe pain, visible deformity, inability to move the arm, or signs of infection (e.g., fever, redness). Follow up with a healthcare provider if pain worsens, swelling persists, or mobility does not improve with treatment.

Tips for Medical Coders

Document the laterality (left shoulder), displacement status, and encounter type (initial for closed fracture) to accurately assign this code. Ensure clinical notes specify the fracture as closed (intact skin) and the encounter as the first treatment episode. Verify that imaging or physical exam findings support the diagnosis of displacement.
