A53.0
BillableLatent syphilis, unspecified as early or late
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code describes syphilis infection that is present in the body but shows no symptoms and has an unknown duration (whether it occurred recently or long ago). The person has tested positive for syphilis but has no active signs of the disease.
Coding Tips
- •Use this code only when the duration of latent syphilis cannot be determined as early (less than 2 years) or late (2 years or more); if duration is known, use A53.11 (early latent) or A53.12 (late latent) instead
- •Latent syphilis requires documentation of positive serological testing; ensure the medical record supports the diagnosis before coding
