S62.304K Unspecified fracture of fourth metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Name of the Condition

• Unspecified fracture of fourth metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Summary

This condition describes a fracture of the fourth metacarpal bone in the right hand that has not healed properly, as indicated by the "nonunion" status. It is a subsequent encounter, meaning it follows an initial injury and requires ongoing care due to delayed or incomplete healing.

Causes

Direct trauma or impact to the hand, such as falls, sports injuries, or accidents, can lead to fractures. Nonunion may occur if the initial injury disrupts blood supply, if the bone fragments are not properly aligned, or if there is insufficient immobilization during healing.

Risk Factors

• High-impact activities or contact sports increasing fracture risk.
• Conditions affecting bone healing, such as diabetes or smoking.
• Inadequate initial treatment or immobilization of the fracture.

Symptoms

• Persistent pain at the fracture site.
• Swelling or tenderness that does not improve over time.
• Limited range of motion in the affected finger or hand.
• Possible deformity or instability in the hand.

Diagnosis

Physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays or CT scans, to confirm nonunion by showing a gap or lack of bone union at the fracture site.

Treatment Options

• Surgical intervention to realign and stabilize the bone, often with plates, screws, or bone grafts.
• Extended immobilization with a cast or splint to support healing.
• Pain management and physical therapy to restore function and strength.

Prognosis and Follow-Up

Prognosis depends on the success of treatment, but many patients achieve healing with appropriate intervention. Regular follow-ups monitor progress and adjust treatment as needed to promote union and recovery.

Complications

• Chronic pain or arthritis in the affected joint.
• Permanent loss of function or mobility in the hand.
• Infection or other surgical risks if intervention is required.

Lifestyle & Prevention

• Avoid high-risk activities until fully healed.
• Use protective gear during sports or manual labor.
• Maintain overall bone health through proper nutrition and exercise.

When to Seek Professional Help

Seek care if pain worsens, swelling persists, or mobility does not improve. Immediate attention is needed for signs of infection, such as redness, warmth, or fever.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with nonunion. Include details on prior treatments, imaging results confirming nonunion, and any surgical interventions. Ensure the code S62.304K is used for the right-hand, fourth metacarpal fracture with nonunion status.
