29 CFR Part 1630, Regulations to Implement the Equal Employment Provisions of the ADA (Title I Regulations with amendments issued through May 2016)

(3) Reasonable accommodation. An individual with a record of a substantially limiting impairment may be entitled, absent undue hardship, to a reasonable accommodation if needed and related to the past disability. For example, an employee with an impairment that previously limited, but no longer substantially limits, a major life activity may need leave or a schedule change to permit him or her to attend follow-up or “monitoring” appointments with a health care provider.
