S42.155K Nondisplaced fracture of neck of scapula, left shoulder, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of neck of scapula, left shoulder, subsequent encounter for fracture with nonunion

Summary

A nondisplaced fracture of the neck of the scapula, left shoulder, refers to a break in the narrow portion of the shoulder blade bone that connects the body of the scapula to the glenoid fossa (shoulder joint), where the bone fragments remain in their normal anatomical alignment. This condition affects the left shoulder and is classified as a subsequent encounter for fracture with nonunion, meaning the fracture has not healed properly after an initial injury. The scapular neck plays a key role in shoulder stability and movement, and a nonunion may impact function due to incomplete bone healing.

Causes

Traumatic injury is the primary cause of fractures to the scapular neck. Common mechanisms include falls from a significant height, motor vehicle accidents, or direct blows to the shoulder or back. Sports-related collisions or forceful impacts during physical activities may also result in this type of fracture. The left shoulder may be affected due to the direction of impact or body positioning during the injury. Nonunion can occur if the fracture fails to heal, often due to inadequate immobilization, poor blood supply, or underlying health conditions.

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.
• Smoking or poor nutrition, which can impair bone healing.

Symptoms

• Persistent pain in the shoulder or upper back
• Limited range of motion in the shoulder
• Swelling or tenderness at the fracture site
• Weakness in the affected arm
• Possible clicking or grinding sensations during movement

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture and evaluate for nonunion. The provider may also review the patient's medical history, including prior injuries and treatment, to determine if the fracture has failed to heal. Additional tests, like bone scans, may be ordered to assess bone healing activity.

Treatment Options

Treatment focuses on promoting bone healing and restoring function. Options may include immobilization with a sling or brace to reduce stress on the fracture site, physical therapy to maintain mobility and strength, and pain management. In some cases, surgical intervention, such as bone grafting or internal fixation, may be necessary to address nonunion. The choice of treatment depends on the severity of the nonunion and the patient's overall health.

Prognosis and Follow-Up

Prognosis varies based on the extent of nonunion and the effectiveness of treatment. With appropriate care, many patients can achieve functional recovery, though some may experience long-term limitations in shoulder movement or strength. Follow-up appointments are essential to monitor healing progress, adjust treatment plans, and address any complications. Regular imaging may be used to assess bone union over time.

Complications

• Chronic pain or discomfort
• Persistent limited range of motion
• Muscle weakness or atrophy
• Increased risk of future fractures
• Potential need for surgical intervention

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Engage in low-impact exercises, such as swimming or walking, to preserve mobility.
• Use protective gear during sports or activities with a risk of falls.
• Quit smoking, as it can impair bone healing.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, increased swelling, or new numbness or tingling in the arm. Prompt evaluation is important if the shoulder becomes increasingly unstable or if you notice a deformity. Follow up with your provider if symptoms do not improve with initial treatment or if you have concerns about healing progress.

Tips for Medical Coders

This code is used for a subsequent encounter for a nondisplaced fracture of the neck of the scapula, left shoulder, with nonunion. Documentation should clearly indicate the fracture's status (nondisplaced), location (left shoulder), and the presence of nonunion. Include details about prior treatment, current symptoms, and any imaging or clinical findings that confirm nonunion. Ensure the encounter is classified as "subsequent" and that the fracture is not healing as expected.
