H16.203

What This Code Means

This code describes inflammation of both the cornea and conjunctiva (the clear membranes covering the eye and inner eyelid) when the specific cause is not identified. The condition affects both eyes equally.

Coding Tips

• •Use this code only when the type of keratoconjunctivitis is not specified or documented; if a specific cause is identified (such as viral, bacterial, or sicca), use the more specific subcategory instead
• •The bilateral designation (code ending in 3) indicates both eyes are affected; verify documentation confirms bilateral involvement before coding, as unilateral cases would use different codes
