S42.022A Displaced fracture of shaft of left clavicle, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of shaft of left clavicle, initial encounter for closed fracture (ICD-10 Code: S42.022A)

Summary

A displaced fracture of the shaft of the left clavicle is a break in the middle portion of the left collarbone where the bone fragments are not aligned. This condition involves the central third of the clavicle and is classified as closed (no skin break) and initial (first encounter for treatment). It typically results from trauma and requires evaluation to determine appropriate management.

Causes

This fracture commonly occurs due to direct trauma to the shoulder or a fall onto an outstretched hand. High-impact events such as motor vehicle accidents, contact sports injuries, or falls from a height can generate sufficient force to break the clavicle shaft and displace the fragments.

Risk Factors

Factors increasing the likelihood of this injury include participation in contact sports, osteoporosis or reduced bone density, and older age due to higher fall risk. Activities involving repetitive upper-body stress or high-impact forces also raise susceptibility.

Symptoms

Symptoms typically include sudden pain in the shoulder or collarbone area, swelling, bruising, tenderness, and difficulty moving the shoulder. A visible bump or deformity at the fracture site may be present, and pain often worsens with arm movement.

Diagnosis

Diagnosis involves a physical examination to assess pain, deformity, and range of motion, followed by X-ray imaging to confirm the fracture and its displacement. Additional imaging may be used if complications are suspected.

Treatment Options

Treatment may include immobilization with a sling, pain management, and physical therapy. Severe displacement or instability may require surgical intervention to realign and stabilize the bone.

Prognosis and Follow-Up

Most fractures heal within 6–12 weeks with proper care. Follow-up appointments monitor healing and functional recovery. Physical therapy may be recommended to restore strength and mobility.

Complications

Potential complications include nonunion, malunion, nerve or blood vessel injury, or chronic pain. Infection is rare but possible if the fracture becomes open.

Lifestyle & Prevention

Preventive measures include using protective gear during contact sports, maintaining bone health through diet and exercise, and fall prevention strategies for older adults.

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). Prompt evaluation is essential for proper management.

Tips for Medical Coders

Document the fracture as displaced, specify the left clavicle, and confirm it is closed and an initial encounter. Include details on trauma mechanism, imaging results, and treatment plan to support code accuracy.
