Late syphilis, unspecified

This code signifies a diagnosis of syphilis in its later stages, where the specific manifestation (e.g., cardiovascular, neurosyphilis, gummatous) is not documented or determined. It indicates a chronic, systemic infection caused by Treponema pallidum that has progressed beyond the primary and secondary stages.

This code is appropriate when a patient has a confirmed diagnosis of late-stage syphilis, but the medical record lacks specific details regarding the particular organ system affected or the precise clinical presentation of the late-stage disease. Documentation supporting its use would include positive serological tests for syphilis (e.g., RPR, VDRL, FTA-ABS) and clinical evidence of late-stage infection without further specificity.

• Avoid using this code if a more specific late syphilis manifestation (e.g., neurosyphilis, cardiovascular syphilis) is documented; use the appropriate specific code instead.
• Ensure documentation clearly indicates "late" syphilis and not early or congenital forms.
• Always review the entire medical record for any mention of specific organ involvement that would allow for more precise coding.
