Keratoconus, stable, right eye

This code signifies a diagnosis of keratoconus in the right eye that is currently stable, meaning the corneal ectasia is not progressing. Keratoconus is a progressive eye disease characterized by the thinning and bulging of the cornea into a cone-like shape, leading to distorted vision. "Stable" indicates that the condition has been monitored and shows no significant change in corneal curvature or thickness over a defined period.

Use this code when documentation confirms a diagnosis of keratoconus affecting the right eye, and clinical assessment indicates the condition is stable. This typically applies after a period of observation where serial topography or pachymetry measurements show no significant progression. Supporting documentation should include ophthalmological examination findings, corneal topography, and pachymetry results confirming stability.

• Ensure documentation explicitly states "stable" or provides evidence of non-progression for the right eye.
• Distinguish from progressive keratoconus (H18.60x, H18.62x, H18.63x) which indicates ongoing changes.
• Always specify laterality (right, left, bilateral, or unspecified) as available in the documentation.
