Medicaid is a medical health insurance available for individuals who are in certain income brackets which qualifies them to acquire this government provided insurance coverage. Whether or not someone qualifies for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify because they make a reasonable income. As an example, men and women who have quite a few dependents may be eligible for Medicaid regardless of whether they make what would be described as a reasonable income. Medicaid may also cover the expense of treatment, when someone has been abusing alcohol or drugs and needs treatment. There are several drug and alcohol rehabilitation programs which accept Medicaid, but different states have different guidelines for what kinds of treatment are covered. Certain states only include outpatient rehab services as an example while other states cover more extensive rehab such as a residential stay in long-term alcohol and drug rehab center. If anyone is involved in substance abuse and wants help, they could use their Medicaid insurance coverage to obtain this treatment. If they do not have Medicaid and also don't have enough cash or any other type of health care insurance to cover rehabilitation, they could find out if they are eligible for a Medicaid and then sign up for an alcohol and drug rehab facility that's approved inside their state.
