Parasitic endophthalmitis, unspecified, bilateral

This code signifies an inflammation of the internal structures of both eyes caused by a parasitic infection, where the specific type of parasite is not identified. This condition can lead to severe vision impairment or loss if left untreated.

Apply this code when documentation confirms parasitic endophthalmitis affecting both eyes, but the causative parasite is not specified. This typically occurs when laboratory identification of the parasite is pending or inconclusive, or when the physician's diagnosis explicitly states "unspecified parasitic endophthalmitis, bilateral."

• Ensure documentation clearly states "bilateral" involvement; otherwise, a unilateral code or an unspecified eye code may be more appropriate.
• Do not use this code if the specific parasite is identified (e.g., toxoplasmosis, onchocerciasis); instead, use the more specific code for that parasitic infection.
• Always sequence this code after the underlying parasitic disease code, if known and applicable.
