Peripheral opacity of cornea, left eye

This code indicates a non-centralized cloudiness or haziness affecting the outer regions of the cornea in the left eye. This opacity can result from various causes, including trauma, inflammation, or degenerative conditions, and may or may not impair vision depending on its density and exact location.

Use this code when documentation specifies an opacity located peripherally on the cornea of the left eye. This diagnosis is typically supported by an ophthalmological examination noting the location and nature of the corneal abnormality. It is appropriate for both new diagnoses and follow-up encounters related to this specific condition.

• Ensure documentation clearly specifies "peripheral" and "left eye" to support this laterality and location.
• Distinguish from central corneal opacities (H17.0-) and other specified corneal opacities (H17.81-).
• Code any underlying cause of the corneal opacity, if known and documented, as an additional diagnosis.
