S52.354E Nondisplaced comminuted fracture of shaft of radius, right arm, subsequent encounter for open fracture type I or II with routine healing

Name of the Condition

Nondisplaced comminuted fracture of shaft of radius, right arm, subsequent encounter for open fracture type I or II with routine healing
ICD-10 Code: S52.354E

Summary

A nondisplaced comminuted fracture of the shaft of the radius involves a break in the long, outer bone of the forearm (radius) between the elbow and wrist, where the bone is shattered into multiple pieces but the fragments remain in their original alignment. This injury is classified as an open fracture type I or II, meaning the skin was breached but the wound is small or moderate, and soft tissue damage is limited. The "subsequent encounter" modifier indicates ongoing care during the healing phase, and "routine healing" confirms the fracture is progressing without complications. Management focuses on monitoring, pain control, and ensuring proper immobilization to support recovery.

Causes

This fracture typically results from high-impact trauma, such as falls onto an outstretched arm, direct blows to the forearm, or accidents involving significant force (e.g., motor vehicle collisions, sports injuries). Twisting injuries or crush mechanisms can also cause the bone to break into multiple fragments while maintaining alignment.

Risk Factors

• Participation in contact sports or activities with a high risk of falls
• Osteoporosis or weakened bone density
• Advanced age, which increases fracture susceptibility
• Previous forearm or wrist injuries
• Occupations or hobbies involving repetitive stress or heavy lifting

Symptoms

• Persistent but improving pain at the fracture site
• Mild swelling or bruising
• Limited range of motion in the forearm or wrist
• Possible visible scarring from the original open wound
• Sensation of stiffness or discomfort during movement

Diagnosis

Diagnosis is confirmed through clinical evaluation and imaging. A physical exam assesses tenderness, swelling, and range of motion. X-rays or CT scans visualize the fracture pattern, confirming the nondisplaced, comminuted nature and the status of healing. Documentation must specify the open fracture type (I or II) and the routine healing trajectory to support the subsequent encounter code.

Treatment Options

Treatment typically includes immobilization with a cast or splint to stabilize the fracture during healing. Pain management with analgesics may be prescribed. Follow-up visits monitor healing progress, and physical therapy may be recommended to restore strength and mobility once the fracture is stable. Wound care for the original open fracture site is continued as needed.

Prognosis and Follow-Up

Prognosis is generally favorable with routine healing, as the fracture fragments remain aligned and complications are minimal. Follow-up appointments are scheduled to assess healing via imaging and clinical evaluation. Most patients regain full function, though recovery time depends on fracture severity and adherence to treatment.

Complications

• Delayed union or nonunion if healing is impaired
• Infection at the original open wound site
• Residual stiffness or reduced range of motion
• Nerve or vascular irritation from scar tissue
• Rarely, progression to a more severe fracture type if trauma recurs

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use protective gear during sports or work involving forearm risk
• Maintain bone health through adequate calcium and vitamin D intake
• Practice fall prevention strategies, especially in older adults
• Follow post-fracture rehabilitation guidelines to restore function

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms (e.g., numbness, discoloration) develop. Contact a provider if the original wound shows signs of infection (redness, pus, fever) or if mobility does not improve as expected.

Tips for Medical Coders

Document the fracture type (open I or II), the subsequent encounter status, and confirmation of routine healing to accurately assign S52.354E. Ensure clinical notes specify the right arm, shaft of the radius, and the absence of displacement or complications. Coding should align with the documented healing trajectory and encounter type.
