S52.364C Nondisplaced segmental fracture of shaft of radius, right arm, initial encounter for open fracture type IIIA, IIIB, or IIIC

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, right arm, initial encounter for open fracture type IIIA, IIIB, or IIIC
ICD-10 Code: S52.364C

Summary

A nondisplaced segmental fracture of the shaft of the radius is a specific type of fracture involving two separate breaks in the long, outer bone of the forearm (radius) between the elbow and wrist, with the bone fragments remaining in their original alignment. This injury typically results from significant trauma and may require stabilization to prevent displacement and restore function. The "right arm" specification indicates the affected side. The "initial encounter for open fracture type IIIA, IIIB, or IIIC" modifier indicates the fracture is open (exposing the bone) and classified by the severity of soft tissue damage, requiring urgent evaluation and treatment.

Causes

This fracture commonly occurs due to direct trauma, such as falls onto an outstretched arm, high-impact blows to the forearm, or accidents involving twisting forces at the wrist or elbow. Motor vehicle collisions, sports injuries, or forceful impacts may also cause the bone to break into multiple segments without misalignment. Open fractures occur when the trauma is severe enough to pierce the skin, exposing the bone to the external environment.

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
• High-energy trauma exposure (e.g., motor vehicle collisions)

Symptoms

• Sudden, severe pain at the injury site
• Swelling, bruising, or deformity of the forearm
• Inability to move the wrist or forearm
• Visible bone protrusion through the skin (open fracture)
• Numbness or tingling in the hand or fingers (possible nerve involvement)
• Bleeding or wound at the fracture site (open fracture)

Diagnosis

Diagnosis is confirmed through clinical evaluation and imaging. A physical exam assesses pain, swelling, deformity, and wound characteristics. Imaging, typically X-rays, visualizes the fracture pattern and confirms nondisplacement. For open fractures, wound assessment determines the type (IIIA, IIIB, or IIIC) based on soft tissue damage severity. Additional tests (e.g., CT scans) may be used to evaluate complex fractures or associated injuries.

Treatment Options

Treatment focuses on stabilizing the fracture and managing the open wound. Nondisplaced fractures may be managed with immobilization (e.g., casting or splinting) and close monitoring. Open fractures require urgent surgical debridement (cleaning) and stabilization (e.g., internal or external fixation) to prevent infection and promote healing. Antibiotics and tetanus prophylaxis are standard for open fractures. Rehabilitation begins once the fracture is stable to restore function.

Prognosis and Follow-Up

Prognosis depends on fracture severity, treatment adherence, and associated injuries. Nondisplaced fractures generally heal well with proper immobilization and follow-up. Open fractures carry a higher risk of infection or complications, requiring closer monitoring. Follow-up includes regular imaging to assess healing and physical therapy to restore mobility and strength. Full recovery may take several months, with activity modifications during healing.

Complications

• Infection (higher risk in open fractures)
• Nonunion or malunion of the fracture
• Nerve or blood vessel damage
• Chronic pain or stiffness
• Compartment syndrome (swelling restricting blood flow)
• Post-traumatic arthritis (long-term joint damage)

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, work)
• Maintain bone health through diet (calcium, vitamin D) and exercise
• Avoid falls by modifying home environments (e.g., removing tripping hazards)
• Follow safety protocols in occupations with trauma risk
• Seek prompt treatment for forearm injuries to prevent complications

When to Seek Professional Help

Seek immediate medical attention for:

• Visible bone protrusion or severe bleeding
• Inability to move the arm or wrist
• Numbness, tingling, or coldness in the hand/fingers
• Worsening pain, swelling, or redness
• Signs of infection (fever, pus, increased warmth)

Tips for Medical Coders

Document the fracture type (nondisplaced segmental), affected side (right arm), and encounter details (initial for open fracture). Specify the open fracture type (IIIA, IIIB, or IIIC) based on soft tissue damage severity. Include clinical notes confirming the fracture pattern, wound characteristics, and treatment provided to support code assignment. Ensure alignment with ICD-10-CM coding guidelines for fracture classification and encounter sequencing.
