A51.43
ICD-10-CMThis code describes eye involvement occurring during the secondary stage of syphilis. It encompasses various ocular manifestations, such as uveitis, retinitis, or optic neuritis, that are a direct result of disseminated Treponema pallidum infection.
Use this code when documentation explicitly states a diagnosis of secondary syphilis with associated ocular complications. This typically occurs weeks to months after the primary infection and requires a confirmed syphilis diagnosis (e.g., positive serology) along with ophthalmological findings consistent with syphilitic oculopathy.
