S52.321F Displaced transverse fracture of shaft of right radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

Displaced transverse fracture of shaft of right radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Summary

A displaced transverse fracture of the shaft of the right radius is a horizontal break in the long outer bone of the forearm (radius) where the broken fragments are misaligned. This injury is classified as an open fracture type IIIA, IIIB, or IIIC, meaning the bone has pierced the skin with significant soft tissue damage, and it represents a subsequent encounter for treatment with routine healing. The fracture typically results from trauma and may affect arm function depending on the degree of displacement and soft tissue involvement.

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. Open fractures may result from the same mechanisms, with the bone penetrating the skin during the injury event.

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

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

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity, followed by imaging studies such as X-rays or CT scans to confirm the fracture type, displacement, and soft tissue involvement. The classification of the open fracture (IIIA, IIIB, or IIIC) is determined by the extent of soft tissue damage and contamination.

Treatment Options

Treatment typically includes stabilization of the fracture, such as casting or surgical fixation, to promote healing. Open fractures require wound care and possible debridement to prevent infection. Physical therapy may be recommended to restore function once healing progresses.

Prognosis and Follow-Up

With routine healing, most fractures heal within the expected timeframe, but recovery depends on the severity of the injury and adherence to treatment. Follow-up appointments monitor healing progress and adjust care as needed. Long-term outcomes may include restored function, though some residual stiffness or weakness is possible.

Complications

• Infection at the fracture site or wound
• Delayed healing or nonunion
• Nerve or blood vessel damage
• Chronic pain or arthritis
• Limited range of motion in the wrist or forearm

Lifestyle & Prevention

• Use protective gear during high-risk activities
• Maintain bone health through diet and exercise
• Avoid falls by modifying home environments (e.g., removing tripping hazards)
• Follow post-injury care instructions to support healing

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible bone protrusion, increased swelling, or signs of infection (e.g., redness, pus). Follow up with a healthcare provider if symptoms worsen or do not improve as expected.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing status to assign this code accurately. Ensure the encounter is classified as subsequent and that the right radius shaft fracture is clearly documented.
