ICD Code A53.9

ICD code A53.9 is syphilis that has not been specified as either primary, secondary, or late stage.

1. Patient presents with clinical signs or symptoms suggestive of syphilis, but the specific stage (primary, secondary, latent, or tertiary) cannot be determined.

2. Laboratory tests indicate a positive result for syphilis, but documentation does not specify the stage or type.

3. Medical record lacks sufficient detail to classify syphilis as congenital, neurosyphilis, or another specific form.

4. Patient history or examination reveals syphilis infection, but the provider is unable to assign a more specific diagnosis due to incomplete information.

5. Syphilis is confirmed, but the clinical documentation does not indicate whether the infection is early or late.
