Bullous keratopathy, right eye

This code describes a condition affecting the right eye where the innermost layer of the cornea (endothelium) is damaged, leading to corneal swelling and the formation of fluid-filled blisters (bullae) on the corneal surface. This damage impairs the cornea's ability to pump fluid, resulting in chronic edema and reduced vision.

Use this code when documentation specifies bullous keratopathy affecting the right eye. This typically occurs as a complication of intraocular surgery (e.g., cataract extraction), trauma, or other corneal diseases. Supporting documentation should clearly indicate the laterality and the presence of corneal bullae or significant corneal edema.

• Ensure laterality is precisely documented; do not use unspecified laterality codes if the right eye is clearly indicated.
• Distinguish from other corneal edema codes (e.g., H18.2- for other and unspecified corneal edema) which do not specify bullae.
• Consider sequencing this code after any underlying cause, such as a complication of a surgical procedure (e.g., T85.318A for mechanical complication of intraocular lens).
