Symptomatic neurosyphilis, unspecified

This code signifies neurosyphilis where the specific type (e.g., meningovascular, general paresis, tabes dorsalis) is not documented, but the patient is exhibiting neurological symptoms attributable to the syphilitic infection. It represents a late-stage manifestation of syphilis affecting the central nervous system, causing a range of neurological impairments.

Use this code when the medical record clearly indicates neurosyphilis with documented neurological symptoms, but the physician has not specified a more precise form of neurosyphilis. This code is appropriate when the documentation supports a diagnosis of neurosyphilis and its symptomatic nature, but lacks the detail for a more specific subcategory.

• Ensure documentation explicitly states "symptomatic neurosyphilis" without further specification.
• Avoid using this code if a more specific type of neurosyphilis (e.g., A52.11, A52.13) is clearly documented.
• Always sequence this code after the underlying condition (syphilis) if applicable, or as the primary diagnosis if it is the reason for the encounter.
