Medicaid is a kind of health insurance available for many people who are in specific income brackets which qualifies them to obtain this government funded 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 because they earn a reasonable income. As an example, men and women who have quite a few dependents may be entitled to Medicaid even if they earn what would be described as a reasonable income. Medicaid could also cover the expense of rehabilitation, if someone has been abusing alcohol or drugs and requires rehab. There are numerous drug rehabilitation facilities which accept Medicaid, but different states have different rules for what types of rehab are covered. Some states only include outpatient rehabilitation services for example while other states cover far more intensive rehab like a residential stay in long-term alcohol and drug treatment program. If someone is involved in drug use and needs help, they could use their Medicaid health coverage to get this help. If they don't have Medicaid plus don't have the money or any other form of medical health insurance to pay for rehab, they could find out if they qualify for Medicaid and then sign up for a drug and alcohol rehabilitation facility that's approved inside their state.
