S62.631K Displaced fracture of distal phalanx of left index finger, subsequent encounter for fracture with nonunion

Name of the Condition

• Displaced fracture of distal phalanx of left index finger, subsequent encounter for fracture with nonunion

Summary

A displaced fracture of the distal phalanx of the left index finger is a break in the bone at the fingertip where the fragments have shifted out of their normal alignment. This subsequent encounter indicates the fracture has failed to heal properly, resulting in nonunion. The condition typically follows initial trauma and may involve persistent pain, limited mobility, and complications related to the unhealed bone.

Causes

This condition is usually caused by traumatic injuries, such as a crush injury, a fall onto the fingertip, or a direct blow to the finger with a hard object. High-impact events or accidents involving forceful contact can lead to the bone breaking and displacing. Nonunion may occur due to inadequate immobilization, poor blood supply, infection, or other factors that impede healing.

Risk Factors

• Participation in activities or sports with a high risk of hand injury.
• Occupational hazards involving manual labor or machinery.
• Pre-existing conditions that weaken bone density, such as osteoporosis.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent pain and swelling at the fingertip.
• Visible deformity or misalignment of the finger.
• Limited range of motion or inability to move the finger.
• Bruising or discoloration around the injury site.
• Possible clicking or grinding sensation with movement.

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays, are typically used to confirm the fracture and evaluate the degree of displacement. Additional imaging, like CT scans, may be used to assess nonunion and bone healing.

Treatment Options

• Immobilization: Continued or revised splinting or casting to stabilize the fracture.
• Surgical intervention: Procedures to realign the bone, remove scar tissue, or promote healing, such as bone grafting or internal fixation.
• Physical therapy: Exercises to restore range of motion and strength after healing.
• Pain management: Medications or other therapies to address discomfort.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. With proper intervention, many patients achieve improved function, though some may experience long-term stiffness or pain. Regular follow-up appointments and imaging are typically required to monitor healing progress.

Complications

• Chronic pain or discomfort.
• Permanent loss of range of motion or function.
• Infection, particularly if surgical intervention is needed.
• Need for additional procedures if initial treatment is unsuccessful.

Lifestyle & Prevention

• Avoid activities that risk finger injury until fully healed.
• Use protective gear during sports or manual labor.
• Maintain bone health through proper nutrition and exercise.
• Follow post-treatment guidelines to support healing.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility declines after treatment. Contact a healthcare provider if signs of infection, such as redness, warmth, or pus, develop.

Tips for Medical Coders

This code is used for a subsequent encounter for a displaced fracture of the distal phalanx of the left index finger with nonunion. Documentation should specify the fracture type, location, and the presence of nonunion. Ensure the encounter is classified as "subsequent" and that the nonunion is clearly noted to support accurate coding.
