S52.364E Nondisplaced segmental fracture of shaft of radius, right arm, subsequent encounter for open fracture type I or II with routine healing

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, right arm, subsequent encounter for open fracture type I or II with routine healing
ICD-10 Code: S52.364E

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 (skin breach with minimal soft tissue damage) and is documented as a subsequent encounter, indicating follow-up care after initial treatment. The "right arm" specification denotes the affected side, and "routine healing" confirms the fracture is progressing without complications. Treatment during this phase focuses on monitoring healing and managing any residual open wound concerns.

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 repetitive stress or heavy lifting

Symptoms

• Persistent mild pain at the injury site during movement
• Minimal swelling or bruising as healing progresses
• Possible residual skin irritation near the original open wound
• Gradual return of forearm and wrist function

Diagnosis

Diagnosis is confirmed through clinical evaluation and imaging, typically X-rays, to assess bone alignment and healing status. The open fracture classification (type I or II) is determined by the extent of soft tissue damage and skin breach. Subsequent encounters require documentation of healing progress, such as callus formation or reduced wound size, to support the "routine healing" designation.

Treatment Options

Treatment during this phase focuses on monitoring healing and managing any residual open wound concerns. This may include periodic imaging to assess bone union, wound care if needed, and physical therapy to restore function. Stabilization devices (e.g., casts, braces) may remain in place or be adjusted based on healing progress. Pain management and activity modification are often recommended to support recovery.

Prognosis and Follow-Up

With routine healing, the prognosis is generally favorable, as nondisplaced fractures tend to heal well with proper care. Follow-up appointments are scheduled to monitor bone union and functional recovery. Most patients regain full or near-full use of the forearm and wrist, though recovery time varies based on individual factors and fracture severity.

Complications

• Delayed union or nonunion of the fracture
• Infection at the original open wound site
• Residual stiffness or reduced range of motion
• Nerve or vascular irritation from healing tissue

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Engage in gradual, supervised physical therapy to restore strength and mobility
• Use protective gear during sports or activities with fall risks
• Maintain bone health through adequate nutrition (e.g., calcium, vitamin D) and exercise

When to Seek Professional Help

Seek care if you experience increasing pain, swelling, or redness at the injury site; signs of infection (e.g., pus, fever); or sudden loss of function in the forearm or wrist. These may indicate complications requiring prompt intervention.

Tips for Medical Coders

Document the encounter as a subsequent visit for an open fracture type I or II with routine healing. Ensure clinical notes specify the fracture’s alignment (nondisplaced), segmental nature, affected side (right arm), and healing status (routine). Code S52.364E is appropriate when the fracture is healing without complications and the open wound is managed routinely.
