A50.32

What This Code Means

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).

Coding Tips

• •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
• •This is a combination code that includes both the congenital syphilis diagnosis and the specific eye complication, so do not code syphilis and chorioretinitis separately
