S42.151A Displaced fracture of neck of scapula, right shoulder, initial encounter for closed fracture

Name of the Condition

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

Summary

A displaced fracture of the neck of the scapula 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 is specific to the right 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 right 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 of the shoulder.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and functional limitations. Imaging tests, such as X-rays, CT scans, or MRIs, are typically used to confirm the fracture, evaluate displacement, and rule out associated injuries. The focus is on determining the extent of the fracture and its impact on shoulder function.

Treatment Options

• Immobilization of the shoulder with a sling or brace to promote healing and reduce pain.
• Pain management with medications like NSAIDs or acetaminophen.
• Physical therapy to restore range of motion and strength once initial healing occurs.
• Surgical intervention may be considered for severe displacement or instability, though many cases heal with conservative management.

Prognosis and Follow-Up

Most displaced fractures of the scapular neck heal with conservative treatment, but recovery may take several weeks to months. Follow-up appointments are necessary to monitor healing and adjust treatment plans. Physical therapy is often recommended to prevent stiffness and restore function. Long-term outcomes depend on the severity of the fracture and adherence to rehabilitation.

Complications

• Chronic pain or stiffness in the shoulder.
• Reduced range of motion or shoulder instability.
• Nerve or blood vessel damage in severe cases.
• Delayed union or nonunion of the fracture if not properly managed.

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 modifying the home environment (e.g., removing tripping hazards).
• Strengthen shoulder muscles to improve stability and reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible deformity, or inability to move the arm after a shoulder injury. Persistent pain, swelling, or difficulty with daily activities also warrants evaluation by a healthcare provider.

Tips for Medical Coders

Document the specific location (right shoulder), displacement, and encounter type (initial, closed fracture) to accurately assign this code. Ensure clinical notes confirm the fracture's displacement and that the injury is being addressed for the first time without associated open wounds. Coding should reflect the precise anatomical site and nature of the fracture as described in the medical record.
