Enforcement Guidance: Reasonable Accommodation and Undue Hardship Under the Americans with Disabilities Act

8. Are there situations in which an employer cannot ask for documentation in response to a request for reasonable accommodation?

Yes. An employer cannot ask for documentation when: (1) both the disability and the need for reasonable accommodation are obvious, or (2) the individual has already provided the employer with sufficient information to substantiate that s/he has an ADA disability and needs the reasonable accommodation requested.

Example A: An employee brings a note from her treating physician explaining that she has diabetes and that, as a result, she must test her blood sugar several times a day to ensure that her insulin level is safe in order to avoid a hyperglycemic reaction. The note explains that a hyperglycemic reaction can include extreme thirst, heavy breathing, drowsiness, and flushed skin, and eventually would result in unconsciousness. Depending on the results of the blood test, the employee might have to take insulin. The note requests that the employee be allowed three or four 10-minute breaks each day to test her blood, and if necessary, to take insulin. The doctor's note constitutes sufficient documentation that the person has an ADA disability because it describes a substantially limiting impairment and the reasonable accommodation needed as a result. The employer cannot ask for additional documentation.

Example B: One year ago, an employer learned that an employee had bipolar disorder after he requested a reasonable accommodation. The documentation provided at that time from the employee's psychiatrist indicated that this was a permanent condition which would always involve periods in which the disability would remit and then intensify. The psychiatrist's letter explained that during periods when the condition flared up, the person's manic moods or depressive episodes could be severe enough to create serious problems for the individual in caring for himself or working, and that medication controlled the frequency and severity of these episodes.

Now, one year later, the employee again requests a reasonable accommodation related to his bipolar disorder. Under these facts, the employer may ask for reasonable documentation on the need for the accommodation (if the need is not obvious), but it cannot ask for documentation that the person has an ADA disability. The medical information provided one year ago established the existence of a long-term impairment that substantially limits a major life activity.

Example C: An employee gives her employer a letter from her doctor, stating that the employee has asthma and needs the employer to provide her with an air filter. This letter contains insufficient information as to whether the asthma is an ADA disability because it does not provide any information as to its severity (i.e., whether it substantially limits a major life activity). Furthermore, the letter does not identify precisely what problem exists in the workplace that requires an air filter or any other reasonable accommodation. Therefore, the employer can request additional documentation.
