H16 Keratitis

Name of the Condition

• Keratitis

Summary

Keratitis is an inflammation of the cornea, the clear front surface of the eye. This condition can cause pain, redness, and vision changes. It may result from infection, injury, or underlying diseases and requires prompt evaluation to prevent complications.

Causes

Keratitis can be caused by bacterial, viral, fungal, or parasitic infections. Non-infectious causes include dry eye, autoimmune disorders, or exposure to irritants like contact lens overuse. Trauma to the eye may also trigger inflammation.

Risk Factors

• Prolonged contact lens wear without proper hygiene.
• History of eye injuries or surgeries.
• Weakened immune system.
• Pre-existing eye conditions like dry eye syndrome.
• Exposure to contaminated water or environments.

Symptoms

• Eye pain, redness, or irritation.
• Blurred vision or sensitivity to light.
• Excessive tearing or discharge.
• Feeling of a foreign object in the eye.
• Reduced visual acuity in severe cases.

Diagnosis

Diagnosis involves a comprehensive eye exam, including slit-lamp microscopy to assess the cornea. Cultures or scrapings may be taken if infection is suspected. Additional tests, such as corneal topography, help evaluate the extent of damage.

Treatment Options

Treatment depends on the cause. Antibiotics or antivirals address infections, while anti-inflammatory drops reduce swelling. Severe cases may require steroid therapy or surgical intervention. Underlying conditions are managed to prevent recurrence.

Prognosis and Follow-Up

With early treatment, most cases resolve without lasting effects. Delayed care can lead to scarring or vision loss. Follow-up appointments monitor healing and adjust treatment as needed. Chronic keratitis may require long-term management.

Complications

Untreated keratitis can cause corneal scarring, permanent vision impairment, or perforation. Secondary infections may worsen outcomes. In severe cases, corneal transplantation may be necessary.

Lifestyle & Prevention

• Practice good contact lens hygiene.
• Avoid swimming or showering while wearing lenses.
• Use protective eyewear during activities with debris.
• Manage dry eye with lubricating drops.
• Seek prompt care for eye injuries or infections.

When to Seek Professional Help

Consult a healthcare provider if symptoms persist beyond 24-48 hours, worsen, or include severe pain, vision loss, or discharge. Immediate care is needed for trauma or suspected infection.

Tips for Medical Coders

Document the specific type of keratitis (e.g., infectious, non-infectious) and any associated factors (e.g., contact lens use, trauma). Include details on laterality (e.g., unilateral/bilateral) and clinical findings to support code assignment. Ensure documentation aligns with the ICD-10-CM guidelines for H16.
