Onchocerciasis with eye involvement, unspecified

This code signifies an ocular manifestation of onchocerciasis, a parasitic infection caused by the nematode Onchocerca volvulus. The "unspecified" designation indicates that the specific type of eye involvement (e.g., keratitis, chorioretinitis, optic atrophy) is not documented.

Use this code when the medical record clearly states a diagnosis of onchocerciasis with eye involvement, but lacks further specificity regarding the exact ocular structure affected. Documentation supporting its use would include physician notes indicating "onchocercal eye disease" or "river blindness with ocular involvement" without detailing the specific pathology.

• Do not use if the specific eye involvement is documented; instead, choose a more specific B73.0 subcategory (e.g., B73.01, B73.02).
• Ensure the documentation explicitly links the eye condition to onchocerciasis.
• Consider sequencing this code as a primary diagnosis if the ocular involvement is the primary reason for the encounter.
