S62.354P Nondisplaced fracture of shaft of fourth metacarpal bone, right hand, subsequent encounter for fracture with malunion

Name of the Condition

• Nondisplaced fracture of shaft of fourth metacarpal bone, right hand, subsequent encounter for fracture with malunion

Summary

A nondisplaced fracture of the shaft of the fourth metacarpal bone in the right hand, with a subsequent encounter for malunion, refers to a break in the midsection of the bone connecting the ring finger to the wrist where the bone fragments remain aligned but have healed in an abnormal position. This code is used for follow-up care after the initial fracture, where healing occurred with malalignment, requiring ongoing management.

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 due to malunion.

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 malunion. Assessment of functional impact from the malaligned healing.

Treatment Options

• Immobilization with a cast or splint to support healing.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength.
• Surgical intervention may be considered for significant malunion affecting function.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Follow-up care focuses on monitoring healing, managing symptoms, and addressing any functional limitations. Regular evaluations help determine if additional treatment is needed.

Complications

• Chronic pain or discomfort.
• Reduced range of motion or grip strength.
• Increased risk of future fractures in the affected area.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through proper nutrition and exercise.
• Avoid repetitive stress on the hand when possible.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility significantly decreases. Consult a healthcare provider if deformity or functional impairment persists.

Tips for Medical Coders

Document the presence of malunion and the subsequent encounter nature of the visit. Ensure clinical notes specify the fracture’s alignment status and any functional impact to support coding accuracy.
