Onchocerciasis with endophthalmitis

This code signifies an ocular manifestation of onchocerciasis, commonly known as river blindness, where the parasitic infection has led to inflammation of the internal structures of the eye. This condition can result in severe visual impairment or blindness if left untreated.

Use this code when documentation clearly indicates a diagnosis of onchocerciasis with specific involvement of the eye's internal structures (e.g., uveitis, chorioretinitis, optic neuritis) due to the parasitic infection. Supporting documentation would include ophthalmological exam findings, positive serology for Onchocerca volvulus, or identification of microfilariae in ocular tissues.

• Always code the underlying parasitic infection (onchocerciasis) first, followed by this code for the ocular complication.
• Do not use this code for other ocular manifestations of onchocerciasis that do not involve endophthalmitis; refer to other B73 subcategories for those.
• Ensure the medical record explicitly links the endophthalmitis to the onchocercal infection.
