Notes on this code

These notes are part of the regulation. They change how the levels above are applied.

  • Note: It is required for the minimum ratings for residuals under diagnostic codes 8000-8025, that there be ascertainable residuals. Determinations as to the presence of residuals not capable of objective verification, i.e., headaches, dizziness, fatigability, must be approached on the basis of the diagnosis recorded; subjective residuals will be accepted when consistent with the disease and not more likely attributable to other disease or no disease. It is of exceptional importance that when ratings in excess of the prescribed minimum ratings are assigned, the diagnostic codes utilized as bases of evaluation be cited, in addition to the codes identifying the diagnoses.

Myasthenia Gravis (VA Diagnostic Code 8025)

Understanding Your VA Disability Rating for Myasthenia Gravis

Myasthenia gravis is a neurological condition rated by the VA under Diagnostic Code 8025, within the body system for Neurological Conditions and Convulsive Disorders. The rating criteria are found in 38 CFR § 4.124a.


Available Rating Level

Under Diagnostic Code 8025, the schedule provides the following:

RatingWhat It Represents
30%Minimum rating

The 30% minimum rating is the baseline evaluation established for this condition. When the VA assigns a rating higher than this prescribed minimum, it is required to cite the specific diagnostic codes used as the basis of that evaluation, in addition to the codes identifying the diagnoses.


What the VA Looks For

Ascertainable residuals are required. For the minimum ratings covering residuals under diagnostic codes 8000–8025, there must be ascertainable residuals of the condition.

How subjective symptoms are handled. Some residuals cannot be objectively verified — for example, headaches, dizziness, and fatigability. The VA approaches these on the basis of the recorded diagnosis. Subjective residuals are accepted when they are:

  • Consistent with the disease, and
  • Not more likely attributable to another disease or to no disease at all.Documentation of higher ratings. The schedule places exceptional importance on proper citation: when a rating in excess of the prescribed minimum is assigned, the diagnostic codes used as the basis for the evaluation must be cited alongside the codes identifying the diagnoses.

This information is drawn directly from the VA rating schedule for Diagnostic Code 8025 under 38 CFR § 4.124a. Individual evaluations depend on the specific evidence and residuals documented in each case.

These criteria are a rendering of § 4.124a, diagnostic code 8025. The official version is the one that governs your rating.

How to claim this

Knowing the criteria is the first half. Getting your file to show them is the second.

  1. Find your level in the stack

    Read each rung against what your medical records already say. The level your records document today is the one the VA can support today.

  2. Name the gap

    Look at the rung above yours and write down exactly what it asks for that your file does not show yet — a diagnosis, a measurement, a prescribed brace, a doctor’s opinion linking it to service.

  3. Claim it by code

    File under diagnostic code 8025 and attach the evidence for the level you are asking for. Other Neurological Conditions and Convulsive Disorders codes may cover your secondary conditions.
