Rosacea conjunctivitis, left eye

This code signifies inflammation of the conjunctiva (the membrane lining the eyelids and covering the white part of the eye) specifically caused by rosacea, affecting the left eye. It is an ocular manifestation of the chronic inflammatory skin condition rosacea.

Apply this code when documentation clearly indicates conjunctivitis as a direct result of rosacea, and the condition is present in the patient's left eye. Supporting documentation should include a diagnosis of rosacea and a clinical assessment confirming rosacea-related conjunctival inflammation.

• Ensure laterality is accurately documented and coded; this code is specific to the left eye.
• Do not code this if the conjunctivitis is due to other causes, even if the patient has rosacea.
• Consider co-coding with a code for the underlying rosacea (e.g., L71.x) to provide a complete clinical picture.
