S62.023G Displaced fracture of middle third of navicular [scaphoid] bone of unspecified wrist, subsequent encounter for fracture with delayed healing

Name of the Condition

• Displaced fracture of middle third of navicular [scaphoid] bone of unspecified wrist, subsequent encounter for fracture with delayed healing

Summary

This condition involves a displaced fracture in the middle third of the navicular (scaphoid) bone, a small bone in the wrist near the base of the thumb. The fracture is displaced, meaning the bone fragments have shifted from their normal position. The encounter is classified as subsequent for a fracture with delayed healing, indicating ongoing management after the initial injury and a healing process that is not progressing as expected.

Causes

Displaced fractures of the scaphoid typically result from a fall onto an outstretched hand (FOOSH). Direct trauma to the wrist, such as a blow or impact, can also cause this injury. Severe twisting injuries or high-impact activities that stress the wrist may lead to displacement of the bone fragments. Delayed healing may occur due to factors like poor blood supply to the scaphoid, inadequate immobilization, or underlying health conditions affecting bone repair.

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 have compromised bone integrity.
• Smoking or other lifestyle factors that impair bone healing.

Symptoms

• Persistent pain and tenderness at the base of the thumb.
• Swelling and bruising around the wrist area that may not resolve with time.
• Limited wrist movement or difficulty gripping objects, even with immobilization.
• Possible numbness or tingling if nerves are affected by the fracture or healing process.

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 determine its characteristics (e.g., displacement, location, and signs of delayed healing). Additional tests may be used to evaluate blood flow to the scaphoid or rule out other complications.

Treatment Options

Treatment focuses on promoting healing and may include extended immobilization with a cast or splint, surgical intervention to stabilize the fracture, or bone grafting to enhance healing. Physical therapy may be recommended once healing progresses to restore wrist function and strength.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, adherence to treatment, and individual healing capacity. Regular follow-up with imaging is typically required to monitor healing progress. Delayed healing may extend recovery time, and some cases may require long-term management to address functional limitations.

Complications

• Nonunion (failure of the bone to heal) or malunion (healing in an incorrect position).
• Avascular necrosis (loss of blood supply to the scaphoid), which can lead to bone death.
• Chronic pain or arthritis in the wrist.
• Nerve damage or persistent numbness/tingling.

Lifestyle & Prevention

• Avoid high-risk activities that may lead to falls or wrist trauma.
• Use protective gear during sports or activities with a risk of wrist injury.
• Maintain bone health through adequate nutrition (e.g., calcium, vitamin D) and exercise.
• Quit smoking, as it can impair bone healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe wrist pain, swelling, or inability to move the wrist after an injury. Contact your healthcare provider if symptoms worsen or do not improve with treatment, or if you notice new numbness, tingling, or color changes in the hand.

Tips for Medical Coders

Document the encounter as subsequent for fracture with delayed healing. Ensure clinical documentation specifies the fracture location (middle third of the navicular/scaphoid bone), displacement, and the reason for delayed healing (e.g., poor blood supply, noncompliance with immobilization). Include details about imaging findings or treatment modifications related to the healing process.
