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

Name of the Condition

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

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 a subsequent encounter, indicating follow-up care for delayed healing. The "right arm" specification denotes the affected side. Treatment focuses on monitoring healing progress and addressing factors contributing to delayed union.

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
• Poor blood supply to the fracture site
• Smoking or other factors impairing healing

Symptoms

• Persistent pain at the injury site beyond the expected healing timeline
• Swelling or bruising that does not resolve with standard care
• Limited range of motion in the wrist or forearm
• Possible visible signs of the original open wound (if applicable)
• Sensation of instability or "giving way" in the arm

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and functional limitations. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture pattern, assess alignment, and evaluate healing progress. The open fracture classification (type I or II) is determined by the extent of soft tissue damage. Additional tests, like blood work or bone scans, may be ordered to identify factors contributing to delayed healing.

Treatment Options

Treatment focuses on promoting bone healing and may include immobilization with a cast or brace, pain management, and physical therapy to restore function. Surgical intervention, such as internal or external fixation, may be considered if displacement occurs or healing does not progress. Wound care is continued if the original open fracture site is still healing. Nutritional support or medications to enhance bone healing may be recommended based on clinical assessment.

Prognosis and Follow-Up

Prognosis depends on the severity of the original injury, patient health, and adherence to treatment. Delayed healing may extend recovery time, but most fractures eventually heal with appropriate care. Follow-up appointments are scheduled to monitor progress through imaging and physical exams. Adjustments to treatment plans are made based on healing response, and activity modifications are advised to avoid re-injury.

Complications

• Nonunion (failure of the bone to heal)
• Malunion (healing in an incorrect position)
• Infection (if the original open wound persists)
• Chronic pain or stiffness
• Nerve or vascular damage (rare)
• Reduced functional mobility in the arm

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Follow a balanced diet rich in calcium and vitamin D to support bone health
• Quit smoking or reduce exposure to nicotine, which impairs healing
• Use protective gear during sports or activities with fall risks
• Engage in gentle range-of-motion exercises as recommended to maintain mobility

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Sudden, severe pain or swelling at the injury site
• Visible deformity or new displacement of the bone
• Signs of infection (e.g., redness, pus, fever)
• Numbness, tingling, or loss of circulation in the hand or fingers
• Inability to move the wrist or forearm despite immobilization

Tips for Medical Coders

This code is specific to a nondisplaced segmental fracture of the radius in the right arm, classified as a subsequent encounter for an open fracture type I or II with delayed healing. Documentation must clearly indicate the fracture type (open I/II), the affected side (right arm), and the reason for delayed healing (e.g., clinical assessment, imaging findings). Ensure the encounter type (subsequent) is supported by prior treatment records and that the open fracture classification aligns with the original injury documentation.
