S62.349 Nondisplaced fracture of base of unspecified metacarpal bone

Name of the Condition

• Nondisplaced fracture of base of unspecified metacarpal bone

Summary

A nondisplaced fracture of the base of an unspecified metacarpal bone involves a small break or crack in the base of one of the hand bones (excluding the thumb), where the bone fragments remain in their normal alignment. This type of injury typically results 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.

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 are typically scheduled to monitor healing and adjust treatment as needed. Full recovery may take several weeks, depending on the individual and the severity of the injury.

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.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid repetitive hand motions that may increase stress on the metacarpals.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling worsens, or movement of the finger becomes increasingly difficult. Immediate care is also recommended if the hand appears deformed or if there is numbness or tingling.

Tips for Medical Coders

Document the specific metacarpal bone involved when possible, as this may impact code specificity. For nondisplaced fractures, ensure clinical notes confirm alignment and lack of displacement to support the diagnosis. Use this code when the metacarpal bone is not specified in the documentation.
