Minor opacity of cornea, unspecified eye

This code signifies a slight, non-specific cloudiness or haziness on the cornea, the transparent outer layer of the eye, that is not severe enough to be classified as a significant scar or ulcer. It indicates a minor corneal abnormality that does not have a specified cause or location within the cornea.

Apply this code when documentation indicates a "minor corneal opacity" or "corneal haze" without further specification of laterality, cause, or specific type of opacity. This is appropriate when the physician notes a subtle corneal change that doesn't fit more specific codes for corneal scars, edema, or other defined opacities.

• Do not use if the laterality (right or left eye) is documented; instead, use the more specific codes for right (H17.811) or left (H17.812) eye.
• Avoid this code if the opacity is described as a "scar," "ulcer," or has a specific etiology (e.g., post-inflammatory, traumatic), as more precise codes exist.
• Ensure documentation clearly states "minor opacity" or similar non-specific terminology to support this code.
