Peripheral opacity of cornea, right eye

This code signifies a non-centralized clouding or haziness affecting the outer regions of the cornea in the right eye. This opacity can result from various causes, including trauma, inflammation, or degenerative conditions, and may impact vision depending on its density and location.

Apply this code when documentation specifies a peripheral corneal opacity in the right eye. This is appropriate for conditions like peripheral corneal scarring, arcus senilis (if specifically documented as an opacity rather than a normal aging change), or other non-centralized corneal opacities.

• Ensure the documentation clearly specifies "peripheral" and the laterality as "right eye."
• Distinguish from central corneal opacities (H17.0-) and unspecified corneal opacities (H17.9-).
• Code any underlying cause of the opacity, if known and documented, in addition to this code.
