A50.32 ICD-10-CM Code: Late congenital syphilitic chorioretinitis

A50.32 is the ICD-10-CM diagnosis code for late congenital syphilitic chorioretinitis. This is an eye infection caused by syphilis that was passed from mother to child before birth, occurring years after birth. It affects the light-sensitive tissue at the back of the eye (retina) and the layer beneath it (choroid). A50.32 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering infections with a predominantly sexual mode of transmission (a50-a64).

A50.32 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

This code is used only for late manifestations of congenital syphilis (typically after age 2 years); verify the patient's age and that syphilis was acquired congenitally, not through other means.
