Cerebrospinal Syphilis — VA Disability Rating (DC 8013)
Diagnostic Code 8013 · 38 CFR §4.124a
What Is It?
Cerebrospinal syphilis is the historical term for neurosyphilis involving the meninges and the underlying brain or spinal cord — the form of late-stage syphilis that produces meningitis-like symptoms (headaches, neck stiffness, cranial nerve palsies), seizures, and a chronic inflammatory infiltrate in the central nervous system. Modern screening and penicillin treatment have made this presentation rare in military populations, but the diagnostic code remains in 38 CFR §4.124a to cover legacy cases and the occasional contemporary case in a veteran with untreated or inadequately treated infection. 38 CFR §4.124a opens the neurological schedule with a bracketed instruction: disability from the diseases it lists "may be rated from 10 percent to 100 percent in proportion to the impairment of motor, sensory, or mental function," referring the rater to the appropriate body system of the schedule for each manifestation. Inside the 8000–8025 block the schedule prints either a single flat percentage, a single minimum rating, or no percentage at all — there is no severity ladder anywhere in it. A Note closing the block adds two conditions: the minimum ratings for residuals require ascertainable residuals, and when a rating above the minimum is assigned, the diagnostic codes used as the basis of that evaluation must be cited alongside the code identifying the diagnosis. DC 8013 is one of the codes that prints nothing at all: its rating cell in §4.124a is empty, so there is no flat percentage and no minimum. The evaluation is built entirely from the residuals — seizures, cognitive impairment, cranial nerve deficits, visual loss, paralysis — each rated under the code that governs it, with those codes cited in the rating decision.
Rating Criteria
| Rating | Criteria |
|---|---|
| See pathways | DC 8013 assigns no percentages of its own — its rating cell in §4.124a is empty. The evaluation is built from the residuals under the codes that govern them: seizures under DC 8910 or DC 8911, cognitive impairment under DC 8045 or the mental-disorder codes, cranial nerve deficits under DC 8205–8212, visual impairment under §4.79, and any paralysis by comparison with the peripheral nerve codes. §4.124a's preamble sets the range at 10 to 100 percent in proportion to the impairment of motor, sensory, or mental function, and the block's closing Note requires the codes used as the basis of evaluation to be cited alongside DC 8013. |
Evidence Needed
Serologic testing — RPR or VDRL with confirmatory FTA-ABS or TP-PA — establishes the syphilis diagnosis. Cerebrospinal fluid analysis showing lymphocytic pleocytosis, elevated protein, and a positive CSF VDRL confirms central nervous system involvement. MRI of the brain and spinal cord documents inflammatory changes, meningeal enhancement, or focal lesions. Because the rating is built from residuals rather than from a table under DC 8013 itself, the evidence that actually moves the percentage is the residual workup: a neurological examination characterizing each deficit, EEG and seizure records where seizures are present, neuropsychological testing where cognition is affected, and ophthalmology testing where vision is affected. Records of antibiotic treatment — typically intravenous penicillin G for 10 to 14 days — document the treatment response. Service treatment records establishing the in-service infection support service connection.
C&P Exam Tips
Bring serology, CSF analysis, brain or spinal cord imaging, the neurology consult, and the antibiotic treatment record. Then bring the evidence for each residual separately, because that is where the percentage comes from — seizure logs, neuropsychological testing, cranial nerve findings, visual field and acuity results. Ask the examiner to describe every residual specifically rather than summarizing severity, and ask that the rating decision cite the codes used for each one; §4.124a's closing Note requires exactly that. Mention any continuing neurology or infectious disease follow-up.
How to File
File VA Form 21-526EZ listing cerebrospinal syphilis under DC 8013 and reference 38 CFR §4.124a. List every residual separately on the form — seizures, cognitive impairment, specific cranial nerve deficits, visual loss — because DC 8013 carries no percentage of its own and those residuals are what the evaluation is built from. Attach serology, CSF analysis, imaging, the neurology consult, and the antibiotic treatment records, plus the workup for each residual you are claiming.
Common Mistakes
Filing without CSF analysis, which is the central study distinguishing cerebrospinal syphilis from non-CNS syphilis. Expecting DC 8013 to carry its own percentage — the rating cell is empty, and a claim that lists only the diagnosis without the residuals gives the rater nothing to evaluate. Assuming syphilis is on a presumptive list: it is not named in 38 CFR §3.309(a) or §3.309(c), so service connection runs through the service treatment records. Accepting a rating decision that does not cite the codes used for each residual, when §4.124a's closing Note requires them.
Frequently Asked Questions
Is cerebrospinal syphilis still a real diagnosis in modern medicine?
It is uncommon but still seen, particularly in immunocompromised patients and in cases of untreated or inadequately treated early syphilis. The clinical picture is what older literature called "cerebrospinal syphilis"; modern terminology usually calls it early or late meningeal neurosyphilis depending on the timing relative to the original infection. Intravenous penicillin is the standard cure, but residual neurological damage can persist after treatment, and it is that damage the rating is built from.
What percentage does DC 8013 pay?
By itself, none. The rating cell beside "8013 Syphilis, cerebrospinal" in 38 CFR §4.124a is empty — the schedule prints no flat figure and no minimum for this code. §4.124a's opening instruction sets the range at 10 to 100 percent in proportion to the impairment of motor, sensory, or mental function, and sends the rater to the appropriate body system for each manifestation. So the percentage is whatever the residuals earn under their own codes, and the Note closing the 8000–8025 block requires those codes to be cited in the decision.
Is neurosyphilis covered by the former prisoner of war presumptives?
No. The POW presumptive list in 38 CFR §3.309(c) covers psychosis, the anxiety states, dysthymic disorder, organic residuals of frostbite, post-traumatic osteoarthritis, atherosclerotic heart disease and hypertensive vascular disease, stroke and its complications, and — for veterans interned 30 days or more — a list of nutritional and gastrointestinal conditions. Syphilis appears nowhere in it, and it is not in the chronic-disease list at §3.309(a) either. Service connection for cerebrospinal syphilis runs through the ordinary pathway: documentation of the in-service infection plus a nexus to the current diagnosis.
