S62.364P Nondisplaced fracture of neck of fourth metacarpal bone, right hand, subsequent encounter for fracture with malunion

Name of the Condition

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

Summary

A nondisplaced fracture of the neck of the fourth metacarpal bone in the right hand, with a subsequent encounter for fracture with malunion, refers to a break in the midsection of the fourth metacarpal bone where the bone fragments remain aligned but have healed in a non-anatomical position. This condition occurs during follow-up care for a previously treated fracture that did not heal properly, resulting in malalignment.

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.
• Inadequate initial fracture immobilization or treatment.

Symptoms

• Persistent pain and swelling in the hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or hand.
• Visible or palpable deformity due to malunion.
• Reduced grip strength or functional impairment.

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 the extent of malunion. Comparison with prior imaging to assess healing progress.

Treatment Options

• Orthopedic referral for evaluation of malunion severity.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength.
• Possible surgical intervention to realign and stabilize the bone if functional impairment is significant.

Prognosis and Follow-Up

Prognosis depends on the degree of malunion and functional impact. Most patients experience improved symptoms with treatment, but residual stiffness or weakness may persist. Regular follow-up appointments are necessary to monitor healing and functional recovery.

Complications

• Chronic pain or discomfort.
• Reduced range of motion in the hand or fingers.
• Long-term functional limitations.
• Increased risk of future fractures due to altered bone structure.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive hand stress or overuse.
• Follow proper safety protocols in occupational settings.

When to Seek Professional Help

Seek immediate medical attention if pain worsens, swelling increases, or new deformity develops. Consult a healthcare provider if hand function does not improve with treatment or if symptoms interfere with daily activities.

Tips for Medical Coders

Document the presence of malunion and the nature of the subsequent encounter (e.g., follow-up care for a healed fracture with malalignment). Include details on imaging findings, functional impact, and any interventions performed. Ensure documentation supports the "subsequent encounter" and "malunion" components of the code.
