S52.364B Nondisplaced segmental fracture of shaft of radius, right arm, initial encounter for open fracture type I or II

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, right arm, initial encounter for open fracture type I or II
ICD-10 Code: S52.364B

Summary

A nondisplaced segmental fracture of the shaft of the radius is a break in the long, outer bone of the forearm (radius) between the elbow and wrist, involving two separate fracture lines that create a free-floating segment of bone without misalignment. This injury is classified as an open fracture type I or II, meaning the skin is breached but with minimal soft tissue damage. The "right arm" specification indicates the affected side, and "initial encounter" denotes the first episode of care for this injury. Treatment focuses on stabilizing the bone and managing the open wound to prevent infection.

Causes

This fracture typically results from significant trauma, such as motor vehicle collisions, falls from height, or direct forceful impacts to the forearm. Twisting injuries or crush mechanisms can also produce the two distinct fracture lines characteristic of a segmental pattern. High-impact events are common triggers due to the force required to break the bone in multiple places while maintaining alignment.

Risk Factors

• Participation in high-risk activities (e.g., contact sports, extreme sports)
• Osteoporosis or reduced bone density
• Advanced age, which increases fracture susceptibility
• Previous forearm or wrist injuries
• Occupations or hobbies involving heavy lifting or repetitive stress

Symptoms

• Severe, localized pain at the injury site
• Visible deformity or swelling of the forearm
• Inability to move the wrist or forearm
• Open wound at the fracture site (for type I or II open fractures)
• Numbness or tingling in the hand or fingers (if nerve involvement occurs)

Diagnosis

Diagnosis is confirmed through clinical evaluation and imaging. A physical exam assesses pain, swelling, deformity, and open wound characteristics. X-rays of the forearm are standard to visualize the fracture pattern, confirm nondisplacement, and rule out associated injuries. CT scans may be used for complex cases to evaluate bone alignment and soft tissue damage. Documentation of the open fracture type (I or II) and affected side (right arm) is critical for coding accuracy.

Treatment Options

Treatment focuses on stabilizing the fracture and managing the open wound. Nondisplaced fractures may be managed with immobilization (e.g., cast or splint) and close monitoring. Open fractures require wound care, antibiotics to prevent infection, and possible surgical intervention (e.g., internal or external fixation) if instability is present. Pain management and physical therapy are often included in the recovery plan.

Prognosis and Follow-Up

Prognosis is generally favorable with proper treatment, especially for nondisplaced fractures. Healing typically occurs within 6–12 weeks, depending on bone health and adherence to immobilization. Follow-up visits monitor healing via X-rays, assess functional recovery, and address any complications. Physical therapy may be recommended to restore strength and range of motion.

Complications

• Infection (risk increased with open fractures)
• Nonunion or delayed union of the fracture
• Nerve or vascular damage (rare but possible)
• Stiffness or reduced mobility in the wrist or elbow
• Chronic pain or deformity if treatment is inadequate

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, construction)
• Maintain bone health through adequate calcium and vitamin D intake
• Avoid falls by using assistive devices if balance is impaired
• Practice proper lifting techniques to reduce forearm strain
• Seek prompt treatment for minor forearm injuries to prevent progression

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Severe pain, swelling, or deformity of the forearm
• An open wound at the injury site
• Numbness, tingling, or loss of circulation in the hand
• Inability to move the wrist or fingers
• Signs of infection (e.g., redness, pus, fever) after injury

Tips for Medical Coders

Document the fracture as nondisplaced, segmental, and involving the right arm. Specify the open fracture type (I or II) and note the initial encounter. Ensure clinical documentation supports the absence of displacement and the open wound classification to justify the code. Verify laterality (right arm) and encounter type (initial) for accuracy.
