A50.30

What This Code Means

This code describes eye problems that develop later in life due to syphilis infection passed from mother to child before birth, when the specific type of eye disease is not identified. The condition affects vision and eye structures as a delayed consequence of untreated congenital syphilis.

Coding Tips

• •Use this code only when the specific type of late congenital syphilitic eye disease cannot be determined; if the ophthalmologic manifestation is documented (such as interstitial keratitis or chorioretinitis), use the more specific A50.31-A50.39 codes instead
• •Verify that the patient has documented congenital syphilis history and that the eye condition is confirmed as syphilis-related; coordinate with ophthalmology documentation to ensure accurate specificity
