About the H15–H22 Code Range
These eye conditions affect the sclera, cornea, iris, or ciliary body. Keratitis means inflammation of the cornea; iridocyclitis means inflammation of the iris and ciliary body.
H15 separates scleritis, episcleritis, and other scleral disorders. Corneal conditions occupy several categories: H16 separates types of keratitis and corneal ulcers, H17 covers scars and opacities, and H18 covers other corneal disorders, including deposits, edema, and deformities.
H20 distinguishes acute, subacute, chronic, and lens-induced iridocyclitis. H21 groups other iris and ciliary body disorders by type, including vascular disorders, cysts, and adhesions. H22 identifies iris and ciliary body disorders in diseases classified elsewhere.
