Recommend allowing billing to cross over days for mobile crisis and 23 hour and/or residential crisis stabilization. Most places will have separate staff and costs for mobile crisis teams, 23 hour observation units, and residential crisis stabilization units. Real life scenario may be person calls and ends up with mobile crisis response, and then is placed in a 23 hour unit. Both the mobile service and the 23 hour unit should be able to be reimbursed and bill for their respective service. This would be especially true if these levels of service were done some by private providers, and some by CSBs.
