Medicaid is a type of health care insurance available for those who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether a person is qualified for Medicaid doesn't only determined by income however, and individuals shouldn't assume they don't qualify just because they earn a good income. As an example, people who have quite a few dependents may be entitled to Medicaid regardless of whether they earn what might be considered a fair income. Medicaid also can cover the costs of rehab, if someone has been abusing alcohol or drugs and needs rehabilitation. There are many drug rehabilitation centers which accept Medicaid, but different states have different rules for what kinds of treatment are covered. Some states only cover outpatient rehab services for example while other states cover more extensive treatment like a residential stay in long-term alcohol and drug rehabilitation center. If a person is involved with substance abuse and needs help, they can use their Medicaid health coverage to obtain this help. If they don't have Medicaid plus don't have the funds or some other type of health care insurance to pay for treatment, they can find out if they qualify for Medicaid and then sign up for a drug and alcohol rehab program that's approved within their state.
