Medicaid is a health insurance available for individuals who are in certain income brackets which qualifies them to receive this government provided insurance coverage. Whether somebody is qualified for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify just because they earn a fair income. For example, individuals who have a lot of dependents may be eligible for Medicaid regardless of whether they earn what can be considered a reasonable income. Medicaid could also cover the expenses of rehab, if someone has been abusing alcohol or drugs and requires rehabilitation. There are numerous drug treatment centers which accept Medicaid, but different states have different rules for what kinds of rehab are covered. Certain states only include outpatient treatment services for example while other states cover far more extensive treatment say for example a residential stay in long-term drug and alcohol treatment program. If someone is involved with drug use and needs help, they are able to use their Medicaid insurance coverage to acquire this help. If they don't have Medicaid and in addition don't have the money or any other kind of medical health insurance to pay for treatment, they could check if they qualify for Medicaid and then sign up for a drug and alcohol treatment facility that is approved inside their state.
