It is not unusual for people engaged in substance abuse to exhaust all resources on their addiction. When it comes time to get help in a Castro Valley, CA. drug rehab program, there may be nothing remaining to cover the costs of such treatment. If the person is not covered by private health insurance in Castro Valley, they will need to self pay in order to receive treatment services. Self pay means that the individual will need to come up with the resources to cover the costs of drug rehabilitation, costs which will vary depending on the treatment option which is being considered. If the self pay option is the only way to pay for drug treatment, prospective treatment clients can work with treatment counselors to determine if any payment assistance can be offered in the form of a reduced rate or sliding scale fee. These payment assistance options for self pay clients are typically decided based on each individual's circumstances which can include personal income and other possible sources of income.
