S52.332F Displaced oblique fracture of shaft of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

Displaced oblique fracture of shaft of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
ICD-10 Code: S52.332F

Summary

A displaced oblique fracture of the shaft of the left radius is a break in the long, outer bone of the forearm (radius) between the elbow and wrist, where the fracture line runs diagonally and the bone fragments are misaligned. This injury is classified as an open fracture type IIIA, IIIB, or IIIC, indicating significant soft tissue damage, and is documented as 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 associated soft tissue involvement.

Causes

This fracture commonly occurs due to direct trauma, such as falls onto an outstretched arm, direct blows to the forearm, or accidents involving twisting forces at the wrist or elbow. High-impact events like motor vehicle collisions or sports injuries can also cause the bone to break in an oblique pattern. Open fractures occur when the bone pierces the skin or the wound communicates with the fracture site, leading to the specified type III classification.

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 injury 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 deformity, swelling, and skin integrity, followed by imaging studies such as X-rays to confirm the fracture type, displacement, and alignment. Additional tests, like CT scans, may be used to evaluate complex fractures or soft tissue damage. The classification of the open fracture (IIIA, IIIB, or IIIC) is determined by the extent of soft tissue injury, contamination, and vascular involvement.

Treatment Options

Treatment focuses on stabilizing the fracture and promoting healing. Options may include immobilization with a cast or splint, surgical intervention to realign and fix the bone with plates or screws, and wound care for open fractures. Physical therapy is often recommended to restore function and strength after healing.

Prognosis and Follow-Up

With proper treatment, most fractures heal within 6–12 weeks, though recovery time may vary based on fracture severity and patient health. Routine follow-up appointments monitor healing progress, and imaging may be repeated to assess bone union. Long-term outcomes depend on the degree of displacement, soft tissue damage, and adherence to rehabilitation.

Complications

Potential complications include infection (especially in open fractures), nonunion or malunion of the bone, nerve or blood vessel damage, chronic pain, and reduced range of motion. Open fractures carry a higher risk of infection due to exposure of the fracture site.

Lifestyle & Prevention

Preventive measures include using protective gear during high-risk activities, maintaining bone health through diet and exercise, and avoiding falls by modifying home environments. For those with osteoporosis, medications and supplements may reduce fracture risk.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible bone protrusion, numbness, or inability to move the arm. Follow up with a healthcare provider if swelling, pain, or deformity worsens, or if signs of infection (e.g., redness, fever) develop.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing status to assign S52.332F accurately. Ensure the encounter is classified as subsequent, with clear evidence of ongoing care for the fracture. Note the left radius and oblique fracture pattern to meet code specificity requirements.
