S62.186K Nondisplaced fracture of trapezoid [smaller multangular], unspecified wrist, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

This condition refers to a break in the trapezoid bone of the wrist where the bone fragments remain in their normal alignment (nondisplaced), but the fracture has failed to heal (nonunion). The trapezoid is one of the small carpal bones on the radial (thumb) side of the wrist, contributing to stability and movement. This is a subsequent encounter, indicating ongoing care for the fracture with nonunion, rather than the initial treatment phase.

Causes

Typically caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the wrist, or a twisting injury. High-impact activities or accidents may also lead to fractures in this specific bone. Nonunion can occur if the fracture does not heal properly due to factors like poor blood supply, inadequate immobilization, or infection.

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 poor nutrition, which can impair bone healing.

Symptoms

• Persistent pain, swelling, and tenderness in the radial side of the wrist.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the hand or fingers.
• No improvement in symptoms despite prior treatment.

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 its healing status. Additional tests may be used to assess blood flow or rule out infection if nonunion is suspected.

Treatment Options

Treatment may include immobilization with a cast or splint to stabilize the wrist, physical therapy to restore function, or surgery to promote healing (e.g., bone grafting or internal fixation). Pain management and activity modification are also part of the care plan.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Regular follow-up with imaging is necessary to monitor healing. Long-term outcomes may vary, with some patients experiencing persistent pain or reduced wrist function.

Complications

• Chronic pain or stiffness in the wrist.
• Reduced range of motion or functional impairment.
• Increased risk of arthritis in the affected joint over time.
• Need for additional interventions if nonunion persists.

Lifestyle & Prevention

• Avoid high-impact activities that risk wrist injury.
• Maintain bone health through proper nutrition (e.g., calcium and vitamin D) and exercise.
• Use protective gear during sports or activities with fall risks.
• Follow post-injury care instructions to support healing.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or there is no improvement in symptoms after initial treatment. Immediate care is needed for signs of infection (e.g., redness, fever) or if the wrist becomes deformed.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with nonunion, ensuring clear clinical notes support the diagnosis. Include details on prior treatments, imaging results, and any surgical interventions. The code S62.186K is specific to nondisplaced trapezoid fractures with nonunion in the wrist, so verify the fracture type and healing status match the documentation.
