This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code describes a skin manifestation of secondary syphilis that doesn't fit into other specified categories. Secondary syphilis occurs weeks to months after initial infection and can cause various rashes and skin lesions.
Coding Tips
- •Use this code only when the skin manifestation of secondary syphilis is not better described by more specific codes (A51.31 for condyloma latum, A51.32 for mucous patches, A51.33 for other rashes)
- •Always verify the stage of syphilis (primary, secondary, latent, or tertiary) is documented before coding, as this affects code selection and treatment decisions
Excludes 1 — Do NOT code together
- late syphilitic leukoderma (A52.79)
