Other late congenital syphilis, symptomatic

This code signifies symptomatic manifestations of late congenital syphilis, acquired from the mother during gestation, that become apparent after two years of age. These symptoms can affect various organ systems, including the skeletal, neurological, and cardiovascular systems, and are not classified as latent or specific late congenital syphilis conditions like interstitial keratitis or neurosyphilis.

Assign this code when documentation clearly indicates a patient presents with active, non-specific symptoms of congenital syphilis that developed after infancy. This includes conditions such as gummas, saber shins, or Hutchinson's teeth, provided they are not explicitly coded elsewhere as specific late congenital syphilis. Supporting documentation should detail the syphilitic etiology and the symptomatic presentation.

• Ensure documentation specifies "congenital" syphilis and "late" onset (after age 2) with active symptoms.
• Differentiate from A50.6 (Late congenital syphilis, latent) which indicates no active symptoms.
• Do not use if a more specific late congenital syphilis code (e.g., A50.3 for late congenital neurosyphilis) is applicable.
