(a) Age. — An individual who is under twenty-one years of age may not be a caregiver unless a sufficient showing, as determined by the bureau, is made to the bureau that the individual should be permitted to serve as a caregiver.
(b) Changing caregiver. — If a patient wishes to change or terminate the designation of the patient’s caregiver, for whatever reason, the patient shall notify the bureau as soon as practicable. The bureau shall issue a notification to the caregiver that the caregiver’s identification card is invalid and must be promptly returned to the bureau.
(c) Denial in part. — If an application of a patient designates an individual as a caregiver who is not authorized to be a caregiver, that portion of the application shall be denied by the bureau. The bureau shall review the balance of the application and may approve that portion of it.
