Other corneal deformities, bilateral

This code signifies the presence of various non-specific structural abnormalities affecting both corneas, excluding conditions like keratoconus, corneal ectasia, or specific degenerative disorders. These deformities can impact corneal shape, curvature, and transparency, potentially affecting visual acuity.

Apply this code when documentation clearly indicates a bilateral corneal deformity that doesn't fit more specific ICD-10-CM codes for corneal conditions. Examples include bilateral corneal irregularities not otherwise specified, or congenital corneal anomalies affecting both eyes without a more precise diagnosis. Supporting documentation should detail the bilateral nature and the specific type of deformity if known, or state "other" if not precisely identified.

• Ensure documentation explicitly states the deformity is bilateral; otherwise, consider laterality-specific codes.
• Always review for more specific codes (e.g., H18.6x for keratoconus, H18.71x for corneal ectasia) before defaulting to "other."
• If a specific cause or underlying condition for the deformity is identified, code that condition first, followed by this code as a manifestation, if applicable.
