VA Disability Rating for Anterior Poliomyelitis (DC 8011)
Diagnostic Code 8011 · 38 CFR §4.124a
What Is It?
Anterior poliomyelitis is the viral destruction of the anterior horn cells of the spinal cord — the lower motor neurons — producing asymmetric flaccid weakness, muscle wasting, and in severe cases respiratory failure. New infections are rare, so the veterans this code reaches are almost always living with residuals of an old infection, or with post-polio syndrome, the new weakness, fatigue, and pain that emerges decades later as the surviving motor neurons that had been compensating begin to fail. Note what the presumptive lists do and do not cover: poliomyelitis appears in neither the chronic-disease list at 38 CFR §3.309(a) nor the tropical-disease list at §3.309(b), so service connection here runs through the direct route or through aggravation of a pre-service infection under 38 CFR §3.306, not through a presumption. 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 8011 prints two figures: 100 percent as active febrile disease, and a minimum of 10 percent once the evaluation moves to residuals.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | As active febrile disease. The schedule assigns 100 percent while poliomyelitis is an active febrile illness. It is an evaluation of the acute phase, not a severity tier, and for most veterans claiming under this code the acute phase is decades in the past. |
| 10% | Rate residuals, minimum. Once the acute illness is over the evaluation is made on the residuals, with 10 percent as the floor and no steps printed between it and 100. §4.124a's preamble and §4.120 both govern what happens above the floor: disability in this field is rated in proportion to the impairment of motor, sensory, or mental function, with partial loss of use of one or more extremities from a neurological lesion rated by comparison with the mild, moderate, severe, or complete paralysis of the relevant peripheral nerves. The Note closing the 8000–8025 block requires ascertainable residuals for the minimum and requires that any rating above it cite the diagnostic codes used as its basis. For polio residuals that means each weakened or paralysed muscle group is evaluated by comparison with the peripheral nerve codes for the affected distribution. |
Evidence Needed
Medical records documenting the original infection and its course anchor the claim, along with any record of bracing, orthotics, or surgery that followed. EMG and nerve conduction studies show the chronic anterior horn cell pattern and distinguish it from other causes of weakness. Because the percentage above the 10 percent floor is built in proportion to impairment, the findings that set it are the quantified ones: strength grade by individual muscle group, limb circumference measurements documenting atrophy, gait and assistive device use, walking distance and standing tolerance, and pulmonary function testing where respiratory muscles were involved. For post-polio syndrome, serial examinations showing new decline decades after a stable baseline are what make the case.
C&P Exam Tips
Ask that each muscle group be tested and graded individually rather than described as generalized weakness — the peripheral nerve codes that build the rating are distribution-specific, so a general note of weakness cannot be cited under any of them. Point out visible atrophy and ask that limb circumference be measured against the unaffected side. Demonstrate your walking with and without devices and report endurance in concrete terms: how far, how long, how often you fall. If you have post-polio syndrome, describe the timeline of new decline against the stable years that preceded it, and report fatigue and pain specifically. Bring the bracing history and any respiratory testing.
How to File
File VA Form 21-526EZ claiming poliomyelitis residuals under DC 8011 and cite 38 CFR §4.124a. Attach the records of the original infection, the EMG, and a current neurological examination with muscle-by-muscle strength grades. Claim each residual by the distribution it affects, because those are the codes an evaluation above the floor must be built from and cited under. If the infection predated service, the argument is aggravation under 38 CFR §3.306 — service records showing the condition at entry and evidence of worsening beyond natural progression during service. If post-polio syndrome developed later on a service-connected foundation, claim it as a progression of that condition rather than as a new disease.
Common Mistakes
Reading 10 / 30 / 60 / 100 as a severity ladder for polio. The schedule prints 100 percent for the active febrile illness and a 10 percent floor for residuals, with nothing between them. Describing weakness generally instead of muscle group by muscle group, which leaves nothing for the nerve codes to attach to. Not claiming post-polio syndrome as a progression. Not claiming the joint damage that decades of abnormal mechanics produce. Assuming a presumptive applies — poliomyelitis is on neither the chronic-disease nor the tropical-disease list.
Frequently Asked Questions
What is post-polio syndrome and can I claim it?
Post-polio syndrome is new progressive weakness, fatigue, joint pain, and reduced endurance appearing 15 to 40 years after recovery from the original infection, understood as the gradual failure of surviving motor neurons that had been carrying an extra load. If the original polio is service-connected, post-polio syndrome is a progression of that condition rather than a separate disease, and the evidence that matters is serial examination showing decline after a long stable period. Document the new weakness by muscle group, since that is how the rating above the floor is assembled.
Is polio a presumptive condition?
No. Poliomyelitis is not in the chronic-disease list at 38 CFR §3.309(a), and it is not in the tropical-disease list at §3.309(b) either. Service connection therefore has to be established directly — records showing the infection occurred in service — or through aggravation under 38 CFR §3.306 where the infection predated service and the residuals worsened beyond natural progression during it. Be careful with sources that suggest otherwise; the presumptive lists are specific, and this code is not on them.
I had polio as a child. Can I claim anything?
Not the polio itself, if the infection predated service — but aggravation is a real route. 38 CFR §3.306 provides that a preexisting condition is service-connected on an aggravation basis where it worsened during service beyond its natural progression, and the physical demands of service on already weakened muscles is exactly the kind of argument that provision exists for. What the claim needs is the entrance examination showing the condition at entry and evidence of measurable worsening during service, not merely symptoms that continued.
