ICD-10 Code A52.7 – Other symptomatic late syphilis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A52.7 – Other symptomatic late syphilis
What it is
A52.7 identifies late syphilis with symptoms that do not fit a more specific late-stage category. Use it for documented symptomatic disease when the record does not name a different late syphilis manifestation.
Clinical signs
Clinical features vary; refer to documentation. Late syphilis may involve neurologic, ocular, cardiovascular, or other organ symptoms, but this code is used only when the provider documents symptomatic late disease without a more specific label.
When to use this code
Use A52.7 when the chart states other symptomatic late syphilis or describes late syphilis symptoms without a more precise diagnosis. It also fits when the provider confirms late-stage syphilis and the record lacks detail for a narrower code.
If the note identifies neurosyphilis, ocular syphilis, or another specific late manifestation, code that condition instead. Check documentation for stage, symptoms, and any more specific clinical diagnosis before assigning A52.7.
Do not use for
Do not use this code for asymptomatic serologic findings, early syphilis, or congenital syphilis. If the record supports a specific late syphilis complication, use the more precise code.
Coding tip
Always look for the provider’s exact late-syphilis wording; unspecified symptoms often indicate a need for clarification or a more specific code.
