Other cerebrospinal syphilis

This code signifies a form of neurosyphilis affecting the brain and spinal cord, excluding general paresis and tabes dorsalis. It encompasses a range of neurological manifestations resulting from chronic syphilitic infection of the central nervous system.

This code is appropriate for patients diagnosed with cerebrospinal syphilis presenting with symptoms such as cranial nerve palsies, meningovascular syphilis, or other non-paretic/non-tabetic neurological deficits due to syphilis. Documentation should clearly indicate a diagnosis of neurosyphilis and specify the absence of general paresis or tabes dorsalis.

• Ensure documentation specifies "other" cerebrospinal syphilis to differentiate from general paresis (A52.11) and tabes dorsalis (A52.13).
• Always code the underlying infectious agent (syphilis) first, followed by the specific manifestation.
• Review the patient's history for prior syphilis diagnoses and treatment to support the chronic nature of the condition.
