Other corneal deformities, right eye

This code signifies a non-specific, acquired or congenital structural abnormality of the right cornea that does not fit into more specific categories like keratoconus, keratoglobus, or other defined corneal ectasias. It encompasses a range of deformities affecting the shape, curvature, or integrity of the corneal surface.

Use this code when documentation specifies a corneal deformity in the right eye that is not otherwise classified. This includes conditions like irregular astigmatism not due to refractive error alone, corneal warpage, or other unspecified structural changes. Documentation should clearly indicate the right eye and the nature of the corneal irregularity.

• Ensure the medical record specifies the right eye; otherwise, an unspecified eye code (H18.799) or bilateral code (H18.793) may be more appropriate.
• Differentiate this code from more specific corneal ectasias (e.g., H18.6x for keratoconus) or corneal scars (H17.xx).
• Always review the documentation for laterality and the specific type of corneal deformity to avoid miscoding.
