Medicaid is a health insurance available for many people who are in specific income brackets which qualifies them to acquire this government provided insurance. Whether or not somebody is qualified for Medicaid doesn't only depend on income however, and individuals shouldn't presume they don't qualify simply because they make a good income. As an example, people who have quite a few dependents may be eligible for Medicaid even when they make what can be considered a fair income. Medicaid could also cover the costs of rehab, if someone has been abusing alcohol or drugs and requires treatment. There are several drug and alcohol rehabilitation centers which accept Medicaid, but various states have different rules for what sorts of treatment are covered. Certain states only include outpatient rehabilitation services as an example while other states cover far more extensive rehab say for example a residential stay in long-term drug treatment program. If a person is involved with substance abuse and needs help, they're able to use their Medicaid insurance coverage to get this help. If they don't have Medicaid and in addition don't have the money or another form of health care insurance to cover rehab, they could find out if they qualify for Medicaid and then sign up for an alcohol and drug rehab program that's approved within their state.
