Folds in Descemet's membrane, bilateral

This code signifies the presence of folds or wrinkles in Descemet's membrane, the innermost layer of the cornea, affecting both eyes. These folds can indicate corneal edema, trauma, or other underlying corneal pathologies.

Use this code when documentation explicitly states "folds in Descemet's membrane, bilateral" or similar phrasing, such as "Descemet's folds, OU." This condition is often observed during slit lamp examination and may be associated with conditions like Fuchs' endothelial dystrophy or post-surgical corneal swelling.

• Ensure the documentation clearly specifies "bilateral" involvement; otherwise, a unilateral code should be used.
• Always code any underlying cause or associated condition, such as corneal edema (H18.81x) or Fuchs' endothelial dystrophy (H18.51x), in addition to this code.
• Do not confuse with corneal striae (H18.89) unless specifically documented as Descemet's membrane folds.
