Keratopathy (bullous aphakic) following cataract surgery, bi

This code describes a specific corneal disease characterized by bullae formation, occurring in both eyes, as a direct consequence of cataract extraction in an aphakic patient. It signifies a complication where the absence of the natural lens (aphakia) contributes to the development of corneal edema and blistering after cataract surgery.

Use this code when documentation clearly indicates bilateral bullous keratopathy that developed following cataract surgery in a patient who is aphakic. The patient's medical record should specify the laterality and the causal link to the prior cataract extraction.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Confirm the patient is aphakic, as this distinguishes it from pseudophakic bullous keratopathy.
• Sequence this code after the primary reason for the encounter, if applicable, or as the primary diagnosis if it is the focus of treatment.
