Medicaid is a type of medical health insurance available for many people who are in certain income brackets which qualifies them to obtain this government provided insurance coverage. Whether or not someone qualifies for Medicaid doesn't only depend upon income however, and individuals shouldn't assume they don't qualify just because they make a fair income. For example, men and women who have quite a few dependents may be eligible for Medicaid regardless of whether they make what might be described as a reasonable income. Medicaid may also cover the expenses of rehab, if a person has been abusing alcohol or drugs and requires rehabilitation. There are several drug and alcohol rehab programs which accept Medicaid, but various states have different rules for what sorts of rehabilitation are covered. Certain states only cover outpatient rehab services for example while other states cover far more intensive treatment like a residential stay in long-term alcohol and drug rehabilitation program. If someone is involved with substance abuse and wants help, they could use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid and in addition don't have the funds or any other form of health care insurance to pay for rehab, they can see if they are eligible for a Medicaid and then sign up for an alcohol and drug rehab facility that's approved within their state.
