S62.342A Nondisplaced fracture of base of third metacarpal bone, right hand, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of base of third metacarpal bone, right hand, initial encounter for closed fracture

Summary

A nondisplaced fracture of the base of the third metacarpal bone in the right hand involves a small break or crack in the bone that connects to the middle finger, where the bone fragments remain in proper alignment. This type of injury typically results from trauma or direct impact to the hand and is classified as a closed fracture (no open wound) during the initial encounter.

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 third metacarpal bone.
• Swelling and bruising around the affected area.
• Difficulty or pain when moving the middle 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. Follow-up appointments are typically scheduled to monitor healing progress, often with repeat imaging to confirm bone alignment. Full recovery may take several weeks, with gradual return to normal activities as tolerated.

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 stress on the hand when possible.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, inability to move the finger, visible deformity, or signs of infection (e.g., redness, pus, fever).

Tips for Medical Coders

Document the specific metacarpal bone (third), hand (right), and encounter type (initial for closed fracture) to ensure accurate coding. Include details on the fracture's alignment (nondisplaced) and whether the fracture is open or closed to support the code selection.
