S62.348A Nondisplaced fracture of base of other metacarpal bone, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of base of other metacarpal bone, initial encounter for closed fracture

Summary

A nondisplaced fracture of the base of another metacarpal bone (excluding the thumb) involves a small break or crack in the bone where the fragments remain in their normal alignment. This injury is classified as a closed fracture, meaning the skin is intact, and it is documented during the initial encounter for treatment. Such fractures typically result from trauma or impact to the hand.

Causes

Direct trauma, such as a fall or blow to the hand. Sports-related injuries or accidents. Repetitive stress or overuse.

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Occupational hazards involving manual labor.

Symptoms

• Pain and tenderness at the base of the affected metacarpal bone.
• Swelling and bruising around the injured area.
• Difficulty or pain when moving the corresponding finger.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, or deformity. Imaging tests, such as X-rays, to confirm the fracture and evaluate its extent. The diagnosis confirms the fracture is nondisplaced and closed, with no skin penetration.

Treatment Options

• Immobilization with a splint or cast: To keep the bones in place while healing.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength.
• Surgery may be required for severe or displaced fractures to realign the bone.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and care. Follow-up appointments monitor healing progress, typically with repeat imaging if symptoms persist. Full recovery may take several weeks, depending on the bone involved and patient factors.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Stiffness or reduced range of motion in the affected finger.
• Chronic pain in rare cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, manual labor).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive hand stress or improper technique during activities.

When to Seek Professional Help

Seek immediate care if pain worsens, swelling increases, or movement becomes impossible. Signs of infection (e.g., redness, pus) or new deformity also require prompt evaluation.

Tips for Medical Coders

Document the fracture as nondisplaced and closed, with confirmation of the initial encounter. Include details on the affected metacarpal bone (excluding the thumb) and any trauma mechanism. Ensure imaging results support the diagnosis to justify code assignment.
