The appointing authority may require an employee who has been absent because of personal illness charged to donated leave credits, prior to and as a condition of return to duty, to be examined, at the expense of the department or agency, by a physician designated by the appointing authority, to establish that such employee is not disabled from the performance of his/her normal duties and that the return to duty will not jeopardize the health of other employees.
