S62.185K Nondisplaced fracture of trapezoid [smaller multangular], left wrist, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of trapezoid [smaller multangular], left wrist, subsequent encounter for fracture with nonunion

Summary

This condition refers to a break in the trapezoid bone of the left wrist where the bone fragments remain aligned (nondisplaced), but the fracture has failed to heal (nonunion) during a subsequent encounter. The trapezoid is a small carpal bone on the radial (thumb) side of the wrist, contributing to stability and movement. Nonunion indicates the fracture did not progress through normal healing stages, requiring further evaluation and management.

Causes

Typically caused by direct trauma to the left wrist, such as a fall onto an outstretched hand, a blow to the wrist, or a twisting injury. High-impact events, like motor vehicle accidents or sports injuries, may also result in this type of fracture. Nonunion can occur due to inadequate immobilization, poor blood supply to the bone, or underlying health conditions affecting healing.

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.
• Smoking or other factors that impair bone healing.
• Conditions like diabetes or vascular disease that affect circulation.

Symptoms

• Persistent pain, swelling, and tenderness in the radial side of the left wrist.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the hand or fingers.
• Possible clicking or grinding sensation during wrist movement.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture and evaluate for nonunion. Additional tests may be ordered to assess bone healing or rule out infection.

Treatment Options

• Immobilization with a cast or splint to stabilize the wrist.
• Surgical intervention, such as bone grafting or internal fixation, to promote healing.
• Physical therapy to restore strength and range of motion.
• Pain management with medications or other modalities.
• Addressing underlying factors that may hinder healing, such as smoking cessation or managing chronic conditions.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Follow-up imaging and clinical evaluations are necessary to monitor healing progress. Recovery may be prolonged, and some patients may experience long-term wrist stiffness or pain.

Complications

• Chronic pain or discomfort in the wrist.
• Persistent limited range of motion.
• Increased risk of future fractures due to weakened bone.
• Infection, particularly if surgical intervention is required.
• Nerve or tendon damage in the wrist area.

Lifestyle & Prevention

• Avoid high-impact activities that risk wrist injury until fully healed.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through adequate nutrition (e.g., calcium, vitamin D) and exercise.
• Follow post-treatment guidelines for immobilization and activity restrictions.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, swelling, or numbness in the wrist; if the injury does not improve with initial treatment; or if you notice signs of infection, such as redness, warmth, or drainage.

Tips for Medical Coders

Document the subsequent encounter for fracture with nonunion, including clinical findings, imaging results, and treatment provided. Ensure the code S62.185K is used for the left wrist, nondisplaced trapezoid fracture with nonunion during a subsequent encounter. Note any contributing factors to nonunion, such as patient history or treatment adherence, to support coding accuracy.
