S62.255 Nondisplaced fracture of neck of first metacarpal bone, left hand

Name of the Condition

• Nondisplaced fracture of neck of first metacarpal bone, left hand

Summary

This condition involves a break or crack in the neck of the first metacarpal bone (the bone connecting the thumb to the wrist) without displacement of the bone fragments. The fracture remains aligned, and the severity and treatment depend on the location and extent of the break.

Causes

Typically caused by direct trauma, such as a fall onto an outstretched hand, a blow to the thumb or hand, or a crushing injury. High-impact activities or accidents may also lead to fractures in this area.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, especially in older adults.
• Previous hand or thumb injuries that may have compromised bone integrity.

Symptoms

• Pain, swelling, and tenderness in the thumb or base of the hand.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the thumb.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture and evaluate its extent.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the hand and allow healing.
• Pain management: Over-the-counter or prescription medications to reduce discomfort.
• Physical therapy: Exercises to restore strength and range of motion after healing.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and follow-up care. Recovery typically takes 4–6 weeks, with gradual return to normal activities. Regular follow-up appointments monitor healing and address any complications.

Complications

• Delayed union or nonunion of the fracture.
• Stiffness or reduced range of motion in the thumb.
• Chronic pain or arthritis in the joint.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by improving balance and home safety.

When to Seek Professional Help

Seek immediate care if pain worsens, swelling increases, or movement becomes impossible. Also, consult a healthcare provider if numbness, tingling, or discoloration develops, as these may indicate nerve or vascular issues.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the left hand. Include details on imaging results, treatment provided, and follow-up care to support accurate coding. Ensure alignment with clinical documentation for the ICD-10-CM code S62.255.
