Late congenital syphilis, latent

This code signifies a diagnosis of congenital syphilis that has progressed beyond two years of age without clinical manifestations of the disease, but serologic tests remain positive. It indicates a quiescent phase of the infection, where the treponemes are still present in the body without causing active symptoms.

Use this code for patients over two years old with a documented history of congenital syphilis and positive serological tests (e.g., VDRL, RPR, FTA-ABS) but no current clinical signs or symptoms of the disease. Documentation should clearly state "latent" and "late congenital syphilis."

• Distinguish from early congenital syphilis (before age 2) and acquired syphilis.
• Ensure documentation specifies "latent" and "late" to differentiate from other stages.
• Always confirm positive serological evidence in the medical record.
