Medicaid is a health care insurance available for many people who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether or not a person qualifies for Medicaid doesn't only depend on their earnings however, and individuals shouldn't presume they don't qualify simply because they make an acceptable income. For instance, people who have many dependents may be eligible for Medicaid even when they make what can be described as a reasonable income. Medicaid could also cover the costs of rehabilitation, if someone has been abusing alcohol or drugs and requires rehab. There are lots of drug rehabilitation centers which accept Medicaid, but various states have distinct rules for what forms of treatment are covered. Certain states only cover outpatient treatment services for instance while other states cover more extensive rehabilitation such as a residential stay in long-term drug rehab center. If a person is involved in substance abuse and wants help, they can use their Medicaid health coverage to get this help. If they don't have Medicaid plus don't have the money or some other type of health care insurance to pay for rehabilitation, they can determine if they qualify for Medicaid and then sign up for an alcohol and drug rehabilitation center that's approved within their state.
