Other cerebrovascular syphilis

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 affects blood vessels in the brain, causing complications like stroke or other neurological problems, excluding the specific condition of general paresis of the insane. This is a late-stage manifestation of untreated syphilis affecting the central nervous system.

Coding Tips

  • •Verify documentation specifies neurosyphilis with cerebrovascular involvement but is NOT general paresis of the insane (GPI), as A52.04 is the specific code for GPI
  • •Ensure the patient has confirmed syphilis diagnosis and documented evidence of cerebrovascular complications such as stroke, aneurysm, or arteritis related to syphilis
