Anterior corneal pigmentations, unspecified eye

This code describes the presence of pigment deposits on the anterior surface of the cornea, without further specification of the exact location or laterality. These pigmentations can be benign or indicative of underlying ocular conditions.

Use this code when documentation indicates "corneal pigmentation" or "pigment on cornea" without specifying if it's posterior, stromal, or the specific eye affected. This code is appropriate when the provider notes anterior corneal pigmentations but does not specify the laterality (right, left, or bilateral).

• Avoid using this code if the laterality is documented; instead, use the more specific codes for right (H18.011), left (H18.012), or bilateral (H18.013) anterior corneal pigmentations.
• Do not confuse with codes for posterior corneal pigmentations (H18.02-).
• Always query the provider for laterality if not documented to allow for more specific coding.
