S62.366A Nondisplaced fracture of neck of fifth metacarpal bone, right hand, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of neck of fifth metacarpal bone, right hand, initial encounter for closed fracture

Summary

A nondisplaced fracture of the neck of the fifth metacarpal bone in the right hand is a break in the midsection of the fifth metacarpal bone where the bone fragments remain aligned. This injury typically results from trauma or impact to the hand, with the fracture not causing significant displacement of the bone fragments. The term "initial encounter" indicates this is the first time the patient is receiving treatment for the fracture, and "closed fracture" means the skin over the fracture site remains intact.

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.

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 nondisplaced fractures of the metacarpal neck heal well with conservative treatment, and patients typically regain full function. Follow-up care involves monitoring healing progress, which may include repeat imaging or clinical assessments. Physical therapy is often recommended to restore strength and range of motion. Recovery time varies but generally ranges from several weeks to a few months, depending on the severity and patient factors.

Complications

• Delayed healing or nonunion of the fracture.
• Stiffness or reduced mobility in the hand or fingers.
• Chronic pain or discomfort.
• Infection (rare, especially with closed fractures).

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.
• Practice proper ergonomics during manual tasks to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, swelling, or deformity after a hand injury. Contact a healthcare provider if symptoms worsen, or if there is difficulty moving the hand or fingers, as these may indicate a more serious injury or complication.

Tips for Medical Coders

Document the specific metacarpal bone (fifth) and hand (right) involved, as well as the fracture type (nondisplaced) and encounter status (initial for closed fracture). Ensure documentation supports the absence of displacement and confirms the fracture is closed (skin intact). Include details of the injury mechanism and any imaging results to validate code assignment.
