S52.362F Displaced segmental fracture of shaft of radius, left arm, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

Displaced segmental fracture of shaft of radius, left arm, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
ICD-10 Code: S52.362F

Summary

A displaced 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, where the bone is separated into two or more fragments that are misaligned. This injury is classified as an open fracture type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and bone exposure. The term "subsequent encounter" denotes ongoing care after the initial treatment phase, and "routine healing" confirms the fracture is progressing without complications. The "left arm" specification indicates the affected side.

Causes

This fracture typically results from direct trauma, such as high-impact falls, motor vehicle collisions, or forceful blows to the forearm. The segmental nature of the break suggests significant force was applied, often involving twisting or bending at the wrist or elbow. Open fractures of this severity may occur in severe accidents or crush injuries.

Risk Factors

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

Symptoms

• Persistent pain at the injury site, even with healing
• Swelling or bruising around the forearm
• Limited range of motion in the wrist or elbow
• Possible residual deformity or tenderness
• Skin changes or scarring from prior open fracture

Diagnosis

Diagnosis involves a physical examination to assess alignment, swelling, and tenderness. Imaging, typically X-rays or CT scans, confirms the fracture pattern, displacement, and healing status. Documentation of the open fracture type (IIIA, IIIB, or IIIC) and routine healing is critical for coding. Clinical notes should detail the fracture’s progression and any residual symptoms.

Treatment Options

Treatment focuses on maintaining alignment and promoting healing. This may include immobilization with a cast or brace, physical therapy to restore function, and monitoring for complications. Surgical intervention is less common in subsequent encounters unless malunion or nonunion occurs. Pain management and activity modification are often part of the care plan.

Prognosis and Follow-Up

With routine healing, most patients recover full or near-full function, though some residual stiffness or weakness may persist. Follow-up appointments monitor healing progress, assess range of motion, and adjust therapy. Long-term outcomes depend on the initial injury severity and adherence to rehabilitation.

Complications

• Delayed union or nonunion of the fracture
• Persistent pain or stiffness
• Nerve or vascular damage (rare in subsequent encounters)
• Infection (historical risk in open fractures)
• Post-traumatic arthritis in the wrist or elbow

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a provider
• Use protective gear during sports or work
• Maintain bone health with calcium and vitamin D (if applicable)
• Follow rehabilitation guidelines to restore strength and mobility

When to Seek Professional Help

Seek care if experiencing increased pain, swelling, or deformity, or if there are signs of infection (e.g., redness, fever). New numbness, tingling, or circulation issues also warrant immediate evaluation.

Tips for Medical Coders

Code S52.362F requires documentation of a displaced segmental fracture of the left radius shaft, open fracture type IIIA, IIIB, or IIIC, and routine healing during a subsequent encounter. Ensure clinical notes specify the fracture type, healing status, and affected side. Avoid coding if the fracture is closed or healing is complicated (e.g., delayed union).
