In the service auth section for Mobile Crisis it indicates that the service is initially registered for up to 32 units and if additional time is required an authorization is submitted that is no greater than 72 hours long. This reads as though the 72 hours is in addition to the first 32units of the registration. Please clarify whether mobile crisis can be for a total of 72 hours from the time of initiation of services or for 72 hours in addition to however long it took to use the 8 hours from the initial registration, as well as the length of stay for the initial registration.
