S62.661P Nondisplaced fracture of distal phalanx of left index finger, subsequent encounter for fracture with malunion

Name of the Condition

• Nondisplaced fracture of distal phalanx of left index finger, subsequent encounter for fracture with malunion (ICD-10 Code: S62.661P)

Summary

A nondisplaced fracture of the distal phalanx of the left index finger with malunion is a break in the tip bone of the finger where the bone fragments remain in their normal anatomical alignment, but healing has occurred with abnormal alignment. This is a subsequent encounter, indicating the fracture has been previously treated and is now in the healing phase with malunion. The distal phalanx is the most distal segment of the finger, and this injury typically results from direct trauma or impact to the fingertip.

Causes

Direct trauma or impact to the fingertip, such as from crushing injuries, falls, or accidents. Severe bending forces applied to the finger, often seen in sports or manual labor, can also cause this fracture. Malunion may occur if the fracture was not properly aligned during initial treatment or if healing was incomplete.

Risk Factors

• Participation in contact sports or activities with a high risk of hand injuries.
• Occupations involving manual labor or handling heavy equipment.
• Prior history of hand or finger fractures.
• Osteoporosis or other conditions that weaken bone density.
• Inadequate immobilization or follow-up after initial fracture treatment.

Symptoms

• Persistent pain, swelling, and tenderness at the fingertip.
• Bruising around the injury site.
• Visible or palpable deformity due to abnormal bone alignment.
• Limited range of motion or difficulty moving the fingertip.
• Numbness or tingling if nerve involvement is present.

Diagnosis

Diagnosis is based on clinical evaluation and imaging studies. A physical examination assesses pain, swelling, deformity, and range of motion. X-rays or other imaging confirm the fracture and evaluate for malunion. The provider reviews the patient’s history, including prior treatment and healing progress, to determine the fracture status.

Treatment Options

Treatment focuses on managing symptoms and addressing malunion. Options may include pain management, physical therapy to improve function, or orthopedic referral for evaluation of surgical correction if functional impairment is significant. Immobilization or splinting may be used to support healing.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Most patients recover with conservative management, but some may experience long-term stiffness or reduced dexterity. Follow-up appointments monitor healing, function, and the need for further intervention.

Complications

• Chronic pain or discomfort.
• Reduced range of motion or stiffness.
• Nerve damage leading to numbness or tingling.
• Aesthetic concerns due to visible deformity.
• Increased risk of future fractures in the affected finger.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Practice proper ergonomics to reduce strain on fingers.
• Maintain bone health through adequate nutrition and exercise.
• Follow post-injury care instructions to support proper healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or function declines. Consult a provider if deformity is noticeable, numbness persists, or there are signs of infection (e.g., redness, warmth, or drainage).

Tips for Medical Coders

Document the fracture status (nondisplaced with malunion) and encounter type (subsequent) clearly. Include details on prior treatment, healing progress, and functional impact to support coding accuracy. Ensure alignment with clinical findings and follow-up care records.
