(1) Patients may revoke their designation of a specific designated provider. The revocation must be in writing using a form developed by the department. The patient must send the revocation to the vendor and give a copy to the designated provider. The vendor must verify the form's authenticity prior to revoking the designated provider and deactivating the designated provider's recognition card.

(2) A patient may designate a new designated provider after revoking a prior designated provider. The new designated provider must receive an authorization form from the patient's authorizing health care practitioner. The new designated provider may then go to a retail outlet to be entered into the database and receive a recognition card.

(3) A person may stop serving as a designated provider by providing a letter to the patient. If the person is currently in the database as a designated provider for the patient, the person shall also submit a form established by the department to the vendor. The vendor shall verify the form's authenticity prior to revoking the designated provider in the database and deactivating the designated provider's recognition card.
