Folds in Descemet's membrane, left eye

This code describes the presence of folds or wrinkles specifically within Descemet's membrane, the innermost layer of the cornea, in the patient's left eye. These folds indicate a structural abnormality or stress within the corneal layers, often associated with corneal edema or other underlying ocular conditions.

Use this code when documentation explicitly states "folds in Descemet's membrane" affecting the left eye, as observed during a slit-lamp examination. This finding is often noted in cases of corneal hydrops, post-surgical corneal changes, or other conditions leading to corneal swelling.

• Ensure the documentation specifies "folds" and not other Descemet's membrane abnormalities like detachments or ruptures.
• Verify the laterality is clearly documented as "left eye" to avoid incorrect coding.
• Always code the underlying cause of the Descemet's membrane folds if known and documented (e.g., corneal edema due to glaucoma).
