A50.59

Billable

Other late congenital syphilis, symptomatic

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

This code describes syphilis that was passed from mother to child before birth and is now causing symptoms in the child after age 2 years, but doesn't fit into other specific late congenital syphilis categories. It represents the long-term effects of untreated maternal syphilis infection during pregnancy.

Coding Tips

  • Verify the patient's age is at least 2 years old, as this is classified as 'late' congenital syphilis; early congenital syphilis (A50.0-A50.2) applies to symptoms appearing before age 2
  • Use this code only when the specific manifestation of late congenital syphilis is not captured by more specific codes (A50.30-A50.57), such as when multiple or atypical symptoms are present
