S62.341 Nondisplaced fracture of base of second metacarpal bone, left hand

Name of the Condition

• Nondisplaced fracture of base of second metacarpal bone, left hand

Summary

A nondisplaced fracture of the base of the second metacarpal bone in the left hand involves a small break or crack in the bone that connects to the index finger, where the bone fragments remain in proper alignment. This type of injury typically results from trauma or direct impact to the hand.

Causes

Direct trauma, such as a fall onto the hand or a blow to the area, is the primary cause. Sports-related injuries, accidents, or repetitive stress may also lead to this fracture.

Risk Factors

• Participation in activities with a risk of hand trauma, such as contact sports or manual labor.
• Reduced bone density, which can increase susceptibility to fractures.
• Inadequate hand protection during high-risk activities.

Symptoms

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

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, or deformity. Imaging tests, such as X-rays, are used to confirm the fracture and verify that the bone fragments are properly aligned.

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, typically within 4–6 weeks. Follow-up appointments monitor healing progress and may include repeat imaging to ensure proper alignment. Full recovery of strength and function is common, but some residual stiffness or mild discomfort may persist temporarily.

Complications

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

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive hand stress or overuse.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, swelling, deformity, or inability to move the finger. Persistent pain or difficulty with daily activities after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the specific location (base of the second metacarpal bone, left hand) and confirm the fracture is nondisplaced. Include details about the encounter type (e.g., initial, subsequent) and whether the fracture is open or closed, as these affect code assignment. Ensure clinical documentation supports the diagnosis to align with coding guidelines.
