S62.318A Displaced fracture of base of other metacarpal bone, initial encounter for closed fracture

Name of the Condition

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

Summary

A displaced fracture of the base of another metacarpal bone, initial encounter for closed fracture, involves a break in the proximal (base) portion of one of the hand bones (excluding the thumb) where the bone fragments are misaligned. This injury occurs during the initial encounter and is classified as closed, meaning the skin is not broken. It typically results from trauma or impact to the hand, leading to pain, swelling, and potential functional impairment.

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 swelling in the hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or hand.
• Possible deformity or misalignment.

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 and displacement.

Treatment Options

• Immobilization with a cast or splint to promote 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 fractures heal within 6-8 weeks with proper immobilization and care. Follow-up appointments monitor healing progress and may include repeat imaging. Physical therapy helps restore function, and full recovery depends on the severity of the fracture and adherence to treatment.

Complications

• Nonunion or delayed healing.
• Malunion (improper healing leading to deformity).
• Stiffness or reduced range of motion.
• Chronic pain.

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 improper lifting techniques.

When to Seek Professional Help

Seek immediate care if severe pain, swelling, or deformity occurs after hand trauma. Contact a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the specific metacarpal bone involved (excluding the thumb) and confirm the fracture is displaced and closed. Note the initial encounter status to ensure accurate coding. Include details of trauma mechanism and clinical findings to support the diagnosis.
