S62.357P Nondisplaced fracture of shaft of fifth metacarpal bone, left hand, subsequent encounter for fracture with malunion

Name of the Condition

• Nondisplaced fracture of shaft of fifth metacarpal bone, left hand, subsequent encounter for fracture with malunion

Summary

A nondisplaced fracture of the shaft of the fifth metacarpal bone in the left hand, with a subsequent encounter for fracture with malunion, refers to a break in the midsection of the bone connecting the little finger to the wrist where the bone fragments remain aligned, but healing has occurred with abnormal alignment. This condition is identified during a follow-up visit after the initial fracture, where the bone has not healed in its proper position.

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 immobilization during initial healing.

Symptoms

• Persistent pain or discomfort in the hand.
• Swelling or tenderness around the affected area.
• Difficulty moving the fingers or hand.
• Visible or palpable deformity due to malalignment.
• Reduced grip strength.

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 correction.
• Possible surgical intervention to realign the bone.
• 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.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and treatment. Follow-up care may include regular imaging to monitor healing and function. Long-term outcomes can include residual stiffness or reduced range of motion if malunion is not corrected.

Complications

• Chronic pain or discomfort.
• Reduced hand function or grip strength.
• Increased risk of future fractures.
• Nerve or tendon irritation due to malalignment.

Lifestyle & Prevention

• Use protective gear during high-impact activities.
• Maintain bone health through proper nutrition and exercise.
• Avoid repetitive stress on the hand.
• Follow post-injury care instructions to prevent malunion.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility decreases. Consult a healthcare provider if deformity is noticeable or if there are signs of infection, such as redness, warmth, or pus.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with malunion. Include details on the extent of malalignment, treatment provided, and any functional limitations. Ensure documentation supports the need for follow-up care or corrective intervention.
