S62.015G Nondisplaced fracture of distal pole of navicular [scaphoid] bone of left wrist, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of distal pole of navicular [scaphoid] bone of left wrist, subsequent encounter for fracture with delayed healing

Summary

A nondisplaced fracture of the distal pole of the navicular (scaphoid) bone in the left wrist involves a small crack or break in the lower portion of this critical wrist bone, with the bone fragments remaining in their normal alignment. This code applies to a subsequent encounter where healing is delayed, requiring ongoing evaluation and management to ensure proper recovery. The scaphoid plays a key role in wrist stability and movement, so delayed healing necessitates careful monitoring.

Causes

Typically results from a fall onto an outstretched hand (FOOSH). Can also occur due to direct trauma to the wrist, such as a blow or impact. May involve twisting injuries or high-force activities that stress the wrist. Delayed healing may be influenced by factors like inadequate immobilization, poor blood supply to the scaphoid, or underlying health conditions.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, particularly in older adults.
• Previous wrist injuries or fractures that may compromise bone integrity.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent pain and tenderness localized to the wrist, especially near the base of the thumb.
• Swelling and bruising around the wrist area that may not resolve as expected.
• Decreased range of motion or difficulty gripping objects.
• Possible numbness or tingling if nerves are affected.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRI, to visualize the fracture and evaluate healing progress. Additional assessments may include checking for signs of nonunion or delayed union, which are common in scaphoid fractures.

Treatment Options

• Prolonged Immobilization: Wearing a cast or splint for an extended period to promote healing.
• Surgical Intervention: Considered if delayed healing persists, such as bone grafting or internal fixation.
• Physiotherapy: Rehabilitation exercises to restore strength and mobility after healing.
• Monitoring: Regular follow-up imaging to track progress and adjust treatment as needed.

Prognosis and Follow-Up

Most nondisplaced scaphoid fractures heal with proper immobilization, but delayed healing may extend recovery time. Prognosis depends on the severity of the delay and adherence to treatment. Follow-up appointments are essential to monitor healing and adjust care plans. Long-term outcomes are generally good with appropriate management.

Complications

• Nonunion or delayed union of the fracture.
• Avascular necrosis (loss of blood supply) to the scaphoid, which can lead to bone death.
• Chronic pain or arthritis in the wrist.
• Reduced range of motion or grip strength.

Lifestyle & Prevention

• Avoid high-risk activities until fully healed.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through proper nutrition and exercise.
• Quit smoking to improve healing potential.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility decreases. Contact a healthcare provider if numbness, tingling, or signs of infection (e.g., redness, fever) occur. Prompt evaluation is necessary if healing does not progress as expected.

Tips for Medical Coders

Use this code for a subsequent encounter where healing is delayed. Document the fracture's status (nondisplaced) and the reason for delayed healing (e.g., inadequate immobilization, poor blood supply). Ensure clinical notes support the "subsequent encounter" and "delayed healing" criteria to justify the code.
