Early congenital syphilis, latent

This code represents a stage of syphilis acquired congenitally, where the infant shows no clinical signs or symptoms of the disease but serologic tests are reactive. It indicates that the infection was transmitted from mother to child during pregnancy or birth, and the disease has progressed beyond the primary and secondary stages but remains asymptomatic.

Use this code when documentation confirms congenital syphilis in an infant, and serologic tests are positive without any active clinical manifestations. This diagnosis is typically made based on maternal syphilis history, infant serology (e.g., RPR, VDRL, FTA-ABS), and the absence of physical signs of early congenital syphilis.

• Differentiate from A50.0 (Early congenital syphilis, symptomatic) which involves active clinical signs.
• Ensure documentation clearly states "latent" and "early" to support this specific code.
• Consider sequencing this code as the primary diagnosis when the latent congenital syphilis is the reason for the encounter.
