Keratopathy (bullous aphakic) fol cataract surgery, left eye

This code describes a specific type of corneal disease, bullous keratopathy, that develops in the left eye after cataract surgery in a patient who is aphakic (lacks a natural lens). This condition is characterized by corneal edema and bullae formation, leading to vision impairment.

This code is appropriate when documentation clearly indicates the development of bullous keratopathy in the left eye as a direct complication of prior cataract extraction, and the patient is aphakic. Supporting documentation would include operative reports of cataract surgery, ophthalmology exam notes detailing corneal findings, and a diagnosis explicitly linking the keratopathy to the aphakic state post-cataract surgery.

• Ensure the documentation specifies "aphakic" to differentiate from pseudophakic bullous keratopathy.
• Verify laterality (left eye) is clearly documented; separate codes exist for the right and bilateral eyes.
• Sequence this code after any primary diagnosis for the underlying reason for the encounter, if applicable, or as the primary diagnosis if it is the sole reason for the visit.
