S62.036A Nondisplaced fracture of proximal third of navicular [scaphoid] bone of unspecified wrist, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of proximal third of navicular [scaphoid] bone of unspecified wrist, initial encounter for closed fracture

Summary

A nondisplaced fracture of the proximal third of the navicular (scaphoid) bone in the unspecified wrist is a break in the upper portion of one of the wrist's small bones, where the bone fragments remain in their normal alignment. This type of fracture typically results from trauma and requires evaluation to ensure proper healing and prevent complications. The term "initial encounter for closed fracture" indicates this is the first visit for a fracture that does not penetrate the skin.

Causes

Typically results from a fall onto an outstretched hand (FOOSH), which applies significant force to the scaphoid bone. Can also occur due to direct trauma, such as a blow or impact to the wrist, or twisting injuries during high-impact activities.

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.

Symptoms

• Pain and tenderness in the wrist, especially at the base of the thumb.
• Swelling and bruising around the wrist area.
• 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 confirm it is nondisplaced. Additional tests may be used to check for associated injuries.

Treatment Options

• Immobilization with a cast or splint to stabilize the bone.
• Pain management with nonsteroidal anti-inflammatory drugs (NSAIDs) or other analgesics.
• Follow-up imaging to monitor healing progress.
• Physical therapy to restore strength and range of motion after immobilization.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and follow-up care. Healing time varies but typically ranges from 6 to 12 weeks. Regular follow-up appointments are necessary to assess healing and adjust treatment as needed. Complications are rare but may include delayed union or nonunion if the fracture does not heal properly.

Complications

• Delayed or nonunion of the fracture.
• Avascular necrosis (loss of blood supply to the bone).
• Post-traumatic arthritis in the wrist.
• Nerve or ligament damage from the initial injury.

Lifestyle & Prevention

• Use protective gear during high-risk activities, such as wrist guards in sports.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid falls by using assistive devices if balance is impaired.
• Strengthen wrist muscles through regular exercise to improve stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe wrist pain, swelling, or deformity after an injury. Also, consult a healthcare provider if symptoms worsen or do not improve with initial treatment, or if you notice numbness, tingling, or changes in skin color.

Tips for Medical Coders

Document the specific location (proximal third of the navicular bone), laterality (unspecified wrist), and encounter type (initial for closed fracture) to ensure accurate coding. Include details about the fracture's displacement status (nondisplaced) and any associated injuries or treatments provided. Verify that the documentation supports the use of this code and aligns with clinical guidelines.
