S62.618K Displaced fracture of proximal phalanx of other finger, subsequent encounter for fracture with nonunion

Name of the Condition

• Displaced fracture of proximal phalanx of other finger, subsequent encounter for fracture with nonunion (ICD-10 Code: S62.618K)

Summary

A displaced fracture of the proximal phalanx of another finger with nonunion is a bone break in the first segment of a finger (excluding the thumb and index finger) where the fragments remain misaligned and have failed to heal properly. This code is used for follow-up care when the fracture does not show signs of progressing toward union during the healing process.

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 cause this type of fracture. Nonunion may result from inadequate immobilization, poor blood supply to the bone, infection, or excessive movement at the fracture site.

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, which can impair bone healing.
• Poor nutrition or underlying medical conditions affecting healing.

Symptoms

• Persistent pain and swelling in the affected finger.
• Bruising around the injury site.
• Visible deformity or misalignment of the finger.
• Limited or no improvement in finger mobility over time.
• Possible clicking or grinding sensations with movement.
• Numbness or tingling if nerves are involved.

Diagnosis

Physical examination by a healthcare professional to assess pain, swelling, and mobility. Imaging tests, such as X-rays, to confirm the fracture and evaluate for nonunion. Additional tests, like CT scans or bone scans, may be used to assess bone healing and blood supply.

Treatment Options

• Surgical intervention, such as bone grafting or internal fixation, to promote healing.
• External fixation devices to stabilize the fracture.
• Physical therapy to improve mobility and strength.
• Pain management with medications or other modalities.
• Addressing underlying factors, such as smoking cessation or nutritional support.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the success of treatment. Follow-up care is essential to monitor healing progress and adjust treatment as needed. Regular imaging and clinical evaluations help assess bone union and functional recovery.

Complications

• Chronic pain or stiffness in the finger.
• Permanent deformity or loss of function.
• Infection at the fracture site.
• Nerve or blood vessel damage.
• Need for additional surgeries if healing does not occur.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Avoid smoking and excessive alcohol, which can impair healing.
• Follow post-injury care instructions carefully to promote proper healing.
• Engage in gentle range-of-motion exercises as recommended by a healthcare provider.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or there is no improvement in symptoms over time. Immediate care is needed for signs of infection, such as redness, warmth, or pus, or if there is loss of sensation or circulation in the finger.

Tips for Medical Coders

This code is specific to a subsequent encounter for a displaced fracture of the proximal phalanx of another finger with nonunion. Document the fracture type, location, and the presence of nonunion clearly. Ensure the encounter is classified as "subsequent" and that the nonunion is explicitly noted in the medical record.
