S62.352K Nondisplaced fracture of shaft of third metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of shaft of third metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Summary

A nondisplaced fracture of the shaft of the third metacarpal bone in the right hand, subsequent encounter for fracture with nonunion, refers to a break in the midsection of the bone connecting the middle finger to the wrist where the bone fragments remain aligned, but healing has not occurred as expected. This code indicates a follow-up visit for a fracture that has failed to unite after an appropriate healing period.

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.
• Poor blood supply to the fracture site.
• Inadequate immobilization during initial healing.

Symptoms

• Persistent pain and swelling in the hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or hand.
• Possible clicking or grinding sensation with movement.
• No visible deformity, but functional impairment may be present.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, or functional limitations. Imaging tests, such as X-rays or CT scans, to confirm the fracture and evaluate for nonunion. Assessment of healing progress compared to expected timelines.

Treatment Options

• Prolonged immobilization with a cast or splint to encourage union.
• Bone stimulation therapies, such as ultrasound or electrical stimulation.
• Surgical intervention, including bone grafting or internal fixation, if nonunion persists.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the underlying cause of nonunion and the effectiveness of treatment. Follow-up visits are essential to monitor healing and adjust treatment plans. Most fractures eventually heal with appropriate intervention, but recovery may be prolonged.

Complications

• Chronic pain or discomfort.
• Persistent functional limitations.
• Increased risk of arthritis in the affected joint.
• Need for additional surgeries if nonunion is not resolved.
• Potential for infection if surgical intervention is required.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or manual labor.
• Maintain bone health through adequate nutrition and exercise.
• Follow immobilization and activity restrictions as advised.
• Attend all scheduled follow-up appointments to monitor healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility declines significantly. Contact a healthcare provider if new symptoms, such as numbness or discoloration, develop. Prompt evaluation is necessary if nonunion is suspected or confirmed.

Tips for Medical Coders

Document the fracture's status (nondisplaced) and the presence of nonunion clearly. Include details of prior treatments and the reason for the subsequent encounter. Ensure the right-hand specification and the "subsequent encounter" context are accurately reflected in the record.
