Bullous keratopathy, left eye

This code describes a condition affecting the left eye where the cornea develops fluid-filled blisters due to endothelial dysfunction. This leads to corneal edema, reduced vision, and discomfort. It is often a complication of intraocular surgery, particularly cataract extraction, or other corneal diseases.

Use this code when documentation specifically indicates bullous keratopathy affecting the patient's left eye. This diagnosis is typically supported by slit-lamp examination findings of corneal edema, epithelial bullae, and reduced visual acuity. It is often seen in patients with a history of ocular surgery or corneal dystrophies.

• Ensure laterality is clearly documented as left eye; separate codes exist for right, bilateral, and unspecified eyes.
• Look for underlying causes such as pseudophakic or aphakic bullous keratopathy, and code those conditions if documented.
• Do not confuse with other forms of corneal edema or dystrophies unless bullae formation is explicitly stated.
