A52.0Cardiovascular and cerebrovascular syphilis

A52.0 is the ICD-10-CM diagnosis code for cardiovascular and cerebrovascular syphilis. It belongs to category A52 (late 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 8 subcodes must be used instead.

Within A52 (late syphilis), A52.0 is specifically for cardiovascular and cerebrovascular syphilis. Related codes cover symptomatic neurosyphilis (A52.1), Asymptomatic neurosyphilis (A52.2), neurosyphilis, unspecified (A52.3), other symptomatic late syphilis (A52.7), latent (A52.8) and unspecified (A52.9).

To report this condition, pick the subcode that matches the documentation: A52.00 (unspecified), A52.01 (aorta), A52.02 (aortitis), A52.03 (endocarditis), A52.04 (arteritis), A52.05 (syphilis), A52.06 (involvement) and A52.09 (syphilis).

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