Parasitic endophthalmitis, unspecified, left eye

This code signifies inflammation of the internal structures of the left eye caused by a parasitic infection, where the specific type of parasite is not identified. It indicates an intraocular inflammatory process resulting from parasitic invasion.

Apply this code when documentation confirms endophthalmitis in the left eye due to a parasitic etiology, but the specific parasitic organism (e.g., Toxoplasma, Onchocerca) is not specified. Supporting documentation would include ophthalmological exam findings, imaging (e.g., ultrasound), and potentially lab results indicating parasitic involvement without definitive species identification.

• Ensure the documentation clearly specifies "left eye" and a parasitic cause for the endophthalmitis.
• If the specific parasite is identified, use a more precise code from the H44.1 series (e.g., H44.11- for toxoplasma).
• Do not use this code if the endophthalmitis is bacterial, fungal, viral, or non-infectious; select the appropriate etiology-specific code.
