S62.172D Displaced fracture of trapezium [larger multangular], left wrist, subsequent encounter for fracture with routine healing

Name of the Condition

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

Summary

This condition describes a displaced fracture of the trapezium bone in the left wrist, where the bone fragments are not aligned properly. The trapezium is a carpal bone at the base of the thumb, and its fracture can impact wrist and thumb function. This code specifically applies to a subsequent encounter during the healing phase, indicating the fracture is progressing as expected without complications.

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 crushing 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. Documentation of routine healing is required to support the subsequent encounter 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.
• Rehabilitation: Physical therapy to restore strength and mobility once healing allows.

Prognosis and Follow-Up

With proper treatment, most fractures heal within 6–8 weeks. Routine follow-up ensures healing progresses as expected. Full recovery of function depends on the severity of the fracture and adherence to rehabilitation.

Complications

• Delayed healing or nonunion if treatment is inadequate.
• Arthritis or chronic pain in the wrist or thumb.
• Nerve or tendon damage from the initial injury.

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 worsens, swelling increases, or mobility does not improve. Signs of infection, such as redness or fever, also require immediate attention.

Tips for Medical Coders

Document the fracture type (displaced), location (left wrist), and encounter type (subsequent) to support this code. Include details of routine healing, such as clinical or radiographic evidence of progress, to justify the "subsequent encounter" designation.
