S62.651K Nondisplaced fracture of middle phalanx of left index finger, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of middle phalanx of left index finger, subsequent encounter for fracture with nonunion (ICD-10 Code: S62.651K)

Summary

A nondisplaced fracture of the middle phalanx of the left index finger is a break in the middle bone segment of the index finger where the bone fragments remain in their normal anatomical alignment. This is a subsequent encounter for a fracture with nonunion, indicating the fracture has not healed properly after an initial injury. The condition involves the middle phalanx, the central bone of the finger, and is specific to the left index finger.

Causes

Direct trauma or impact to the finger, such as from falls, sports injuries, or accidents. Crushing injuries or severe bending forces applied to the finger can also result in this fracture. Nonunion may occur due to inadequate immobilization, poor blood supply, infection, or other factors that impede healing.

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.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent pain, swelling, and tenderness in the affected finger.
• Bruising around the injury site.
• Limited range of motion or difficulty moving the finger.
• Possible stiffness or discomfort with movement.
• Visible or palpable gap at the fracture site in some cases.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays or CT scans, to confirm the fracture and evaluate for nonunion. Additional tests may be ordered to assess bone healing or rule out infection.

Treatment Options

• Immobilization with a splint or cast to stabilize the finger.
• Pain management with medications or other therapies.
• Surgical intervention, such as bone grafting or fixation, if nonunion persists.
• Physical therapy to restore function and strength.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Follow-up care is essential to monitor healing and adjust treatment as needed. Long-term outcomes may include persistent pain or reduced function if healing is incomplete.

Complications

• Chronic pain or discomfort.
• Reduced range of motion or stiffness.
• Infection at the fracture site.
• Need for additional surgery.
• Long-term disability or functional impairment.

Lifestyle & Prevention

• Avoid activities that risk finger injury until fully healed.
• Use protective gear during sports or manual labor.
• Maintain bone health with proper nutrition and exercise.
• Follow medical advice for immobilization and rehabilitation.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or movement becomes more limited. Contact a healthcare provider if signs of infection, such as redness, warmth, or pus, develop.

Tips for Medical Coders

Document the fracture type (nondisplaced), location (middle phalanx of left index finger), and encounter type (subsequent for nonunion) clearly. Include details on imaging, treatment, and follow-up to support code assignment. Ensure documentation aligns with the specific criteria for S62.651K.
