Parasitic endophthalmitis, unspecified, right eye

This code signifies an inflammatory condition within the right eye caused by a parasitic infection, where the specific type of parasite is not documented. Endophthalmitis is a severe intraocular inflammation that can lead to significant vision loss if not promptly treated.

Use this code when documentation confirms parasitic endophthalmitis affecting the right eye, but the causative parasite is not identified. This typically occurs when laboratory testing for parasite identification is pending, inconclusive, or not performed. Supporting documentation includes ophthalmology notes detailing clinical signs of endophthalmitis and a confirmed or suspected parasitic etiology.

• Always strive for greater specificity if the parasitic organism is identified (e.g., toxoplasmosis, onchocerciasis).
• Ensure laterality is clearly documented as "right eye" to support this specific code.
• Code any underlying parasitic infection (e.g., B58.01 for ocular toxoplasmosis) in conjunction with this code if known.
