Central corneal opacity, unspecified eye

This code signifies a non-specific opacification located in the central part of the cornea, the transparent outer layer of the eye. This opacity can impair vision by interfering with light transmission to the retina. It does not specify the underlying cause or the exact nature of the opacity.

Use this code when documentation indicates a central corneal opacity without further specification of the affected eye or the etiology. This is appropriate when the physician notes "central corneal opacity, unspecified eye" or similar, and no laterality is documented. It serves as a placeholder until more specific information becomes available.

• Avoid using this code if the laterality (right, left, or bilateral) is documented; instead, use the more specific H17.11, H17.12, or H17.13.
• Do not use this code if the cause of the corneal opacity is known and documented (e.g., H17.0- for adherent leucoma, H17.8- for other corneal opacities).
• Always query the provider for more specific information regarding laterality and etiology if possible, to allow for more precise coding.
