Keratoconus, unspecified, right eye

This code signifies a diagnosis of keratoconus, a progressive, non-inflammatory corneal ectasia characterized by corneal thinning and a conical protrusion, affecting the right eye. The "unspecified" nature indicates that the specific stage or type of keratoconus is not documented.

Apply this code when medical record documentation confirms keratoconus in the right eye, but lacks further specificity regarding its stage (e.g., stable, progressive, acute hydrops). This code is appropriate when the physician's diagnosis explicitly states "keratoconus, right eye" without additional detail.

• Do not use this code if the medical record specifies the stage or type of keratoconus; instead, choose a more specific code from the H18.6 series.
• Ensure laterality is clearly documented as "right eye" to support the use of this specific code.
• Consider querying the provider for further specificity if the documentation is ambiguous regarding the stage or type of keratoconus.
