S62.032P Displaced fracture of proximal third of navicular [scaphoid] bone of left wrist, subsequent encounter for fracture with malunion

Name of the Condition

Displaced fracture of proximal third of navicular [scaphoid] bone of left wrist, subsequent encounter for fracture with malunion

Summary

A displaced fracture of the proximal third of the navicular (scaphoid) bone in the left wrist, with malunion, refers to a break where bone fragments have shifted out of alignment and healed improperly. This condition occurs during a subsequent encounter for the fracture and requires evaluation to address functional impairment or complications from the malunion.

Causes

Direct trauma to the left wrist, such as a fall onto an outstretched hand, is the primary cause. Malunion may develop if initial treatment was inadequate, or if the fracture did not heal in proper alignment.

Risk Factors

• Participation in contact sports or activities with a high risk of wrist injury
• Osteoporosis or weakened bone density
• Previous wrist fractures or ligament damage
• Delayed or incomplete initial fracture management

Symptoms

• Persistent pain and swelling in the left wrist, particularly on the thumb side
• Limited wrist mobility or stiffness
• Visible or palpable deformity at the fracture site
• Difficulty gripping objects or performing fine motor tasks
• Possible clicking or grinding sensations during wrist movement

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRI, to confirm malunion and evaluate fracture alignment. Functional assessments may be used to determine the impact on wrist mechanics.

Treatment Options

• Orthopedic consultation to evaluate malunion severity
• Physical therapy to improve range of motion and strength
• Pain management with nonsteroidal anti-inflammatory drugs (NSAIDs) or other appropriate medications
• Possible surgical intervention, such as osteotomy or bone grafting, for significant functional impairment
• Immobilization with a brace or splint if instability is present

Prognosis and Follow-Up

Prognosis depends on the degree of malunion and functional impact. Regular follow-up with an orthopedic specialist is recommended to monitor healing and adjust treatment. Most patients experience improved function with appropriate management, though some may have residual limitations.

Complications

• Chronic pain or arthritis in the wrist joint
• Reduced grip strength or range of motion
• Increased risk of future fractures due to altered bone structure
• Nerve compression or vascular issues from malaligned bone fragments

Lifestyle & Prevention

• Avoid high-impact activities that stress the wrist until cleared by a healthcare provider
• Use wrist protection during sports or manual labor
• Maintain bone health through adequate calcium and vitamin D intake
• Follow post-treatment guidelines to support proper healing

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Sudden increase in pain, swelling, or deformity
• Inability to move the wrist or fingers
• Signs of infection, such as redness, warmth, or pus at the fracture site
• Numbness or tingling in the hand or fingers

Tips for Medical Coders

Document the subsequent encounter for fracture with malunion, including clinical notes confirming malunion and its impact on function. Ensure documentation supports the need for follow-up care and any interventions related to the malunion. Code S62.032P is specific to the left wrist and requires clear identification of the fracture site and malunion status.
