S62.246 Nondisplaced fracture of shaft of first metacarpal bone, unspecified hand

Name of the Condition

• Nondisplaced fracture of shaft of first metacarpal bone, unspecified hand

Summary

This condition involves a break or crack in the shaft of the first metacarpal bone, the long portion 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 injury.

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, ensuring no displacement is present.

Treatment Options

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

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Follow-up appointments monitor healing progress, and physical therapy may be recommended to regain full function. Recovery typically takes 4–6 weeks, depending on the individual.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Stiffness or reduced range of motion in the thumb or hand.
• Rarely, infection or nerve damage at the injury site.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if balance is impaired.

When to Seek Professional Help

Seek immediate care if pain worsens, swelling increases, or there is numbness, tingling, or loss of circulation in the thumb or hand.

Tips for Medical Coders

Document the nondisplaced nature of the fracture and specify the hand (unspecified) as per the code. Ensure clinical notes confirm no displacement and align with the ICD-10-CM guidelines for accurate coding.
