In general, if a diagnosing clinician makes a grave error in diagnosis, is it possible to later invalidate the diagnosis on the basis of insufficiency, lack of evidence, poor judgment, or other similar reason?
For example, if someone accidentally ended up in a situation where he/she was diagnosed with a mental disorder according to the DSM, but the symptoms according to the DSM do not correspond at all to reality (For example, at least the main symptoms are missing, the study admission was less then the official time needed to diagnose someone with a specific disorder, or a similar reason), can the diagnosis be fully expunged from their medical record upon a sufficient showing of such insufficiency?
I'm not asking about getting a second opinion, refusing treatment, or getting a discharge from treatment - I'm asking about fully eradicating or expunging a diagnosis to the point where it never really "existed" at all in a medical or medicolegal sense. In the practice of law, a legal judgment, order, or document can often be "voided", "vacated", "quashed", "overturned" or "invalidated" by a court if it is shown to have been issued in error. Is there any similar thing in the practice of medicine?
This sort of question is, perhaps, not very interesting or relevant for the majority of patients, but it can be very relevant for persons who must undergo formal "fitness for duty" evaluations or must "pass" medical background checks. For example, someone aspiring to become a pilot who has a history of treatment for schizophrenia, but is currently "ok", must normally undergo a grueling, time consuming, and expensive evaluation process. If such a person could get some sort of medical evaluation stating that they never really "had" schizophrenia to begin with, that could allow them to answer "no" on the applicable medical background check forms and obtain licensure that much more easily. This question may also be relevant to victims of gaslighting - if a person was given a clinical "label" as a result of abuse inflicted upon them, removing the "stigma" of having the "label" may be a valuable form of healing even if the person doesn't have any pressing legal need to have the diagnosis formally removed.
