A50.3Late congenital syphilitic oculopathy

A50.3 is the ICD-10-CM diagnosis code for late congenital syphilitic oculopathy. It belongs to category A50 (congenital syphilis), block A50-A64 (infections with a predominantly sexual mode of transmission) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within A50 (congenital syphilis), A50.3 is specifically for late congenital syphilitic oculopathy. Related codes cover early congenital syphilis, symptomatic (A50.0), early congenital syphilis, latent (A50.1), early congenital syphilis, unspecified (A50.2), late congenital neurosyphilis [juvenile neurosyphilis] (A50.4), other late congenital syphilis, symptomatic (A50.5), late congenital syphilis, latent (A50.6), late congenital syphilis, unspecified (A50.7) and unspecified (A50.9).

To report this condition, pick the subcode that matches the documentation: A50.30 (unspecified), A50.31 (keratitis), A50.32 (chorioretinitis) and A50.39 (oculopathy).

Don't report A50.3 together with the conditions in its Excludes1 note: Hutchinson's triad (A50.53).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
