A52.00

Billable

Cardiovascular syphilis, unspecified

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 has spread to and is affecting the heart and blood vessels, but the specific type or location of damage is not specified. It represents a late-stage complication of untreated syphilis infection.

Coding Tips

  • Use this code only when cardiovascular involvement from syphilis is documented but the specific manifestation (such as aortitis, aneurysm, or valve disease) is not clearly specified; if a specific cardiovascular manifestation is documented, use a more specific A52.0x code
  • Verify that the patient has a confirmed syphilis diagnosis and that cardiovascular involvement is explicitly documented in the medical record before assigning this code
