S62.173D Displaced fracture of trapezium [larger multangular], unspecified wrist, subsequent encounter for fracture with routine healing

Name of the Condition

• Displaced fracture of trapezium [larger multangular], unspecified wrist, subsequent encounter for fracture with routine healing

Summary

This condition describes a displaced fracture of the trapezium bone in the wrist, with routine healing during a subsequent encounter. The trapezium is a carpal bone at the base of the thumb, and displacement means the bone fragments are not aligned. This code applies when the fracture is healing as expected, following initial treatment. The unspecified wrist indicates the side is not documented, and the subsequent encounter denotes follow-up care after the initial fracture management.

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 alignment. Documentation of routine healing is required for this code.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the area and promote healing.
• Pain management: Medications or therapies to reduce discomfort.
• Physical therapy: Exercises to restore strength and mobility once healing allows.
• Monitoring: Regular follow-up to ensure proper healing progress.

Prognosis and Follow-Up

With appropriate treatment, most displaced trapezium fractures heal well, though some may require ongoing care. Follow-up appointments are important to assess healing and adjust treatment as needed. Full recovery may take several weeks to months, depending on the severity.

Complications

• Persistent pain or stiffness in the wrist or thumb.
• Nonunion or delayed healing of the fracture.
• Arthritis in the thumb joint over time.
• Nerve or tendon damage in severe cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by using assistive devices if needed.
• Practice proper wrist and thumb mechanics during daily tasks.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility does not improve. Contact a healthcare provider if numbness, tingling, or signs of infection (e.g., redness, fever) occur.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with routine healing. Ensure the trapezium fracture is confirmed and displacement is noted. The unspecified wrist indicates the side is not documented, and routine healing must be clinically supported. Follow guidelines for subsequent encounter coding and fracture healing documentation.
