Medicaid is a form of health care insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance coverage. Whether an individual qualifies for Medicaid doesn't only depend on their earnings however, and individuals shouldn't assume they don't qualify because they earn an acceptable income. As an example, men and women who have a lot of dependents may qualify for Medicaid even when they earn what might be considered a reasonable income. Medicaid also can cover the expense of treatment, when someone has been abusing alcohol or drugs and requires rehab. There are several alcohol and drug treatment programs which accept Medicaid, but different states have distinct rules for what kinds of rehabilitation are covered. Some states only include outpatient rehabilitation services as an example while other states cover far more extensive rehabilitation such as a residential stay in long-term drug treatment center. If someone is involved in substance abuse and desires help, they can use their Medicaid health coverage to get this help. If they do not have Medicaid and also don't have the cash or another form of health care insurance to pay for rehabilitation, they could check if they are eligible for a Medicaid and then enroll in a drug rehabilitation program that's approved within their state.
