2021 ICD-10-CM Codes for Keratitis (H16)

Clinical Terms for Keratitis (H16)

Keratitis-. Inflammation of the cornea.

Corneal Ulcer-. Loss of epithelial tissue from the surface of the cornea due to progressive erosion and necrosis of the tissue; usually caused by bacterial, fungal, or viral infection.

Keratoconjunctivitis-. Simultaneous inflammation of the cornea and conjunctiva.

Corneal Neovascularization-. New blood vessels originating from the corneal veins and extending from the limbus into the adjacent CORNEAL STROMA. Neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as TRACHOMA, viral interstitial KERATITIS, microbial KERATOCONJUNCTIVITIS, and the immune response elicited by CORNEAL TRANSPLANTATION.
