A52.2

What This Code Means

This is a condition where a person has syphilis bacteria in their nervous system and cerebrospinal fluid, but they don't currently have any symptoms or signs of neurological disease. It's detected through testing rather than patient complaints.

Coding Tips

• •Asymptomatic neurosyphilis requires documented evidence of CNS involvement (positive CSF serology or other confirmatory testing) without clinical neurological symptoms to distinguish it from latent syphilis
• •This code should be used only when neurosyphilis is confirmed; if only serological evidence of syphilis exists without CNS involvement confirmation, use the appropriate latent syphilis code instead
