About the H17 Code Range
Corneal scars and opacities are scars and cloudy areas of the cornea. The subdivisions distinguish where an opacity appears and whether a scar or opacity has a more specific description.
H17.0 identifies adherent leukoma, a type of corneal opacity. H17.1 identifies central opacity. Under other scars and opacities, H17.81 identifies minor opacity, H17.82 peripheral opacity, and H17.89 other scars and opacities. The adherent leukoma, central, minor, and peripheral branches distinguish right, left, both, or unspecified eye. H17.9 identifies an unspecified corneal scar and opacity.
