Other secondary syphilis of skin

This code represents cutaneous manifestations of secondary syphilis, excluding specific conditions like condyloma latum. These skin lesions, often maculopapular, can appear anywhere on the body during the secondary stage of the infection. It indicates a systemic infection with dermatological involvement beyond the primary chancre.

Use this code when documentation specifies "secondary syphilis" with skin involvement, such as a rash, papules, or other non-specific dermatological findings, but explicitly excludes condyloma latum. This code is appropriate when the provider's diagnosis clearly indicates the secondary stage of syphilis affecting the skin, and no more specific code for a particular skin lesion is applicable.

• Ensure documentation differentiates between primary, secondary, and latent syphilis stages.
• Do not code this with A52.79 (late syphilitic leukoderma) as per the Excludes1 note.
• If condyloma latum is present, use A51.31 instead.
