What This Code Means
A50.30 is the ICD-10-CM diagnosis code for late congenital syphilitic oculopathy, unspecified. 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. A50.30 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).
A50.30 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.
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.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A50.30 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
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
