• Keratoconjunctivitis-. simultaneous inflammation of the cornea and conjunctiva.
• Keratoconjunctivitis Sicca-. drying and inflammation of the conjunctiva as a result of insufficient lacrimal secretion. when found in association with xerostomia and polyarthritis, it is called sjogren's syndrome.

Specific Coding for Other keratoconjunctivitis

Non-specific codes like H16.29 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for other keratoconjunctivitis:

Patient Education

Corneal Disorders

Your cornea is the outermost layer of your eye. It is clear and shaped like a dome. The cornea helps to shield the rest of the eye from germs, dust, and other harmful matter. It also helps your eye to focus. If you wear contact lenses, they float on top of your corneas.

Problems with the cornea include:

• Refractive errors
• Allergies
• Infections
• Injuries
• Dystrophies - conditions in which parts of the cornea lose clarity due to a buildup of cloudy material

Treatments of corneal disorders include medicines, corneal transplantation, and corneal laser surgery.

Pink Eye

Conjunctivitis is the medical name for pink eye. It involves inflammation of the outer layer of the eye and inside of the eyelid. It can cause swelling, itching, burning, discharge, and redness. Causes include:

• Bacterial or viral infection
• Allergies
• Substances that cause irritation
• Contact lens products, eye drops, or eye ointments

Pink eye usually does not affect vision. Infectious pink eye can easily spread from one person to another. The infection will clear in most cases without medical care, but bacterial pink eye needs treatment with antibiotic eye drops or ointment.
