S62.173A Displaced fracture of trapezium [larger multangular], unspecified wrist, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of trapezium [larger multangular], unspecified wrist, initial encounter for closed fracture

Summary

This condition describes a break in the trapezium bone of the wrist, with displacement of the bone fragments. The trapezium is a carpal bone located at the base of the thumb, and its fracture can impact wrist and thumb mobility. Displacement indicates the bone fragments are not aligned properly, and this is an initial encounter for a closed fracture (no open wound). Treatment may be needed to restore function.

Causes

Typically caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the thumb or wrist, or a twisting injury. High-impact activities or accidents may also lead to fractures in this area.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, especially in older adults.
• Previous wrist injuries or fractures.

Symptoms

• Pain, swelling, and tenderness at the base of the thumb.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the thumb.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and thumb mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture and evaluate its extent and displacement.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the area and promote healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Surgical intervention: May be required for severe displacement to realign and fix the bone fragments.

Prognosis and Follow-Up

Most fractures heal with proper treatment, but recovery time varies. Follow-up appointments monitor healing and may include physical therapy to restore strength and mobility. Long-term outcomes depend on fracture severity and adherence to treatment.

Complications

• Chronic pain or stiffness in the wrist or thumb.
• Arthritis in the affected joint over time.
• Nerve or tendon damage from the injury or treatment.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by improving balance and home safety.

When to Seek Professional Help

Seek care if pain is severe, swelling worsens, or movement is impossible. Immediate attention is needed for open wounds, numbness, or signs of infection.

Tips for Medical Coders

Document the fracture as displaced, specify the wrist as unspecified, and note it is an initial encounter for a closed fracture. Ensure clinical details align with the code’s definition to support accurate coding.
