Keratoconus, stable, bilateral

This code describes a chronic, non-inflammatory corneal ectasia affecting both eyes, where the cornea thins and bulges into a cone-like shape, but the progression has halted. "Stable" indicates that the condition is no longer worsening, as confirmed by serial topographic measurements.

Use this code when documentation explicitly states bilateral keratoconus that has been determined to be stable. This often follows a period of active progression or after interventions like corneal collagen cross-linking (CXL) have successfully stabilized the condition. Documentation should include evidence of stability, such as comparative topography reports.

• Do not use this code for progressive keratoconus; specific codes exist for active progression.
• Ensure documentation clearly specifies "bilateral" and "stable" to support this code.
• Consider sequencing this code after any codes for active treatment or procedures that led to stabilization.
