S52.364F Nondisplaced segmental fracture of shaft of radius, right arm, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, right arm, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
ICD-10 Code: S52.364F

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 IIIA, IIIB, or IIIC, indicating significant soft tissue damage with extensive contamination or tissue loss. The "right arm" specification denotes the affected side, and "subsequent encounter" refers to follow-up care after the initial treatment phase. "Routine healing" indicates the fracture is progressing normally without complications. Treatment focuses on monitoring healing, managing soft tissue recovery, and restoring function.

Causes

This fracture typically results from high-energy 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. The open fracture classification suggests the trauma was severe enough to breach the skin and damage surrounding soft tissues.

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 pain at the injury site, though less severe than initial trauma
• Swelling or bruising around the forearm
• Limited range of motion in the wrist or elbow
• Possible visible scarring or tissue changes from the open fracture
• Sensation of instability or discomfort during movement

Diagnosis

Diagnosis is confirmed through clinical evaluation and imaging. A physical exam assesses pain, swelling, and range of motion. X-rays or CT scans visualize the fracture pattern and confirm the nondisplaced, segmental nature. The open fracture type is determined by the extent of soft tissue damage observed during examination. Follow-up imaging may be used to monitor healing progress.

Treatment Options

Treatment focuses on supporting routine healing and managing soft tissue recovery. This may include immobilization with a cast or brace to stabilize the bone, physical therapy to restore function, and monitoring for signs of infection or complications. Wound care is emphasized for the open fracture site, and pain management is provided as needed. Surgical intervention is typically not required unless displacement or nonunion occurs.

Prognosis and Follow-Up

With routine healing, the prognosis is generally favorable, though recovery may take several months. Follow-up appointments monitor fracture alignment, soft tissue healing, and functional recovery. Physical therapy is often recommended to restore strength and mobility. Most patients regain full use of the arm, but residual stiffness or weakness may persist.

Complications

• Infection at the open fracture site
• Delayed union or nonunion of the fracture
• Persistent pain or stiffness
• Nerve or vascular damage from the initial trauma
• Limited range of motion in the wrist or elbow

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use protective gear during sports or risky activities
• Maintain bone health through a balanced diet and regular exercise
• Follow post-injury care instructions to support healing
• Attend all follow-up appointments to monitor progress

When to Seek Professional Help

Seek immediate care if you experience increased pain, swelling, redness, or drainage at the injury site, as these may indicate infection. Contact your provider if you notice numbness, tingling, or changes in skin color, which could signal nerve or vascular issues. Follow up as scheduled to ensure proper healing.

Tips for Medical Coders

Use this code for a nondisplaced segmental fracture of the right radius shaft with an open fracture type IIIA, IIIB, or IIIC, documented as a subsequent encounter with routine healing. Ensure the fracture type and healing status are clearly recorded in the medical record. Verify the affected side (right arm) and that the encounter is for follow-up care, not initial treatment.
