S62.016K Nondisplaced fracture of distal pole of navicular [scaphoid] bone of unspecified wrist, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of distal pole of navicular [scaphoid] bone of unspecified wrist, subsequent encounter for fracture with nonunion

Summary

A nondisplaced fracture of the distal pole of the navicular (scaphoid) bone in the unspecified wrist involves a break in the lower portion of this small, critical bone without displacement of the fragments. This type of fracture typically results from trauma and requires evaluation to determine appropriate management, as the scaphoid plays a key role in wrist stability and movement. The "subsequent encounter for fracture with nonunion" indicates the patient is in a follow-up phase where the fracture has failed to heal within the expected timeframe.

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.

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.

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.
• 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 assess for nonunion. Additional tests may be ordered to evaluate blood flow or bone healing.

Treatment Options

• Immobilization with a cast or splint to stabilize the wrist.
• Surgical intervention, such as bone grafting or internal fixation, if nonunion persists.
• Physical therapy to restore range of motion and strength.
• Pain management with medications or other modalities.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Follow-up imaging and clinical evaluations are necessary to monitor healing. Long-term outcomes may include persistent pain or reduced wrist function if the fracture does not heal properly.

Complications

• Chronic pain or arthritis in the wrist.
• Reduced range of motion or stiffness.
• Nerve damage leading to numbness or weakness.
• Increased risk of future fractures.

Lifestyle & Prevention

• Avoid high-risk activities that may cause wrist injuries.
• Use protective gear during sports or physical activities.
• Maintain bone health through proper nutrition and exercise.
• Seek prompt medical attention for wrist injuries to prevent complications.

When to Seek Professional Help

• Persistent or worsening pain, swelling, or bruising.
• Difficulty moving the wrist or gripping objects.
• Numbness, tingling, or weakness in the hand or fingers.
• Signs of infection, such as redness, warmth, or drainage.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with nonunion. Include details about the fracture's location (distal pole of navicular [scaphoid] bone), wrist side (unspecified), and the nonunion status. Ensure clinical documentation supports the nonunion diagnosis and subsequent encounter timing.
