S42.021A Displaced fracture of shaft of right clavicle, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of shaft of right clavicle, initial encounter for closed fracture (ICD-10 Code: S42.021A)

Summary

A displaced fracture of the shaft of the right clavicle is a break in the middle portion of the right 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 or pressure.

Diagnosis

Diagnosis involves a physical examination to assess pain, deformity, and range of motion, followed by X-ray imaging to confirm the fracture, displacement, and rule out other injuries. Additional imaging like CT or MRI may be used for complex cases to evaluate fragment alignment or associated soft tissue damage.

Treatment Options

Treatment may include immobilization with a sling to support the arm, pain management, and physical therapy to restore mobility. Severe or unstable displaced fractures may require surgical intervention to realign and stabilize the bone.

Prognosis and Follow-Up

Most displaced clavicle fractures heal well with appropriate treatment, though recovery time varies. Follow-up appointments monitor healing progress, and physical therapy helps restore strength and function. Complications are rare but may include nonunion or malunion if untreated.

Complications

Potential complications include nonunion (failure to heal), malunion (poor alignment), nerve or blood vessel injury, or chronic pain. Infection risk is low for closed fractures but may increase with surgical intervention.

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. Avoiding high-impact activities that strain the shoulder may reduce risk.

When to Seek Professional Help

Seek immediate care for severe pain, visible deformity, inability to move the arm, or signs of infection (e.g., redness, fever). Persistent pain or limited mobility after initial treatment also warrants medical evaluation.

Tips for Medical Coders

Document the fracture as displaced, specify the right clavicle shaft, and confirm it is closed and an initial encounter. Ensure clinical notes support the displacement and laterality to justify the code. Omit modifiers unless additional documentation specifies them.
