Minor opacity of cornea, left eye

This code signifies a slight clouding or haziness on the surface of the left eye's cornea. This opacity is typically small and does not significantly impair vision, often resulting from minor trauma, inflammation, or degenerative changes.

Apply this code when documentation specifies a "minor corneal opacity" or "mild corneal haze" affecting the left eye. Supporting documentation should clearly indicate the laterality and the non-severe nature of the opacity, often noted during a slit lamp examination.

• Ensure the documentation explicitly states "left eye" for laterality. If unspecified, query the provider.
• Distinguish from more severe corneal opacities (e.g., H17.0- for adherent leukoma) or opacities due to specific causes (e.g., H17.1- for central corneal opacity).
• This code is for the opacity itself; code any underlying cause (e.g., corneal scar, keratitis) separately if documented.
