In general, funding is a mixture of federal, state, local, self-pay and insurance sources. The largest portion is from Fee for Service, which includes all third party and out of pocket payments. The second largest revenue source is from the state; those funds include Mental Health Reform and State Aid. The majority of that money comes from the Department of Social and Rehabilitation Services' community mental health funds. Local funding from the 20 counties is the third largest source. There is an additional category of "Other" that is a catchall for funds not attributable to the primary sources. At this point federal funding is hardly on the funding radarscope.
This mixture makes it financially possible to offer sliding-scale fees, to individuals, based on an ability to pay. Those who can afford to pay full fee are expected to do so. Certain services, not required by state licensure nor supported by state funds are offered at an established fee, unrelated to income.
