Medicaid is a type of medical health insurance available for those who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether someone qualifies for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify just because they make a good income. For instance, people who have quite a few dependents may qualify for Medicaid even though they earn what might certainly be a fair income. Medicaid can also cover the costs of treatment, when someone has been abusing alcohol or drugs and requires treatment. There are numerous drug rehabilitation facilities which accept Medicaid, but different states have different rules for what forms of rehab are covered. Some states only include outpatient treatment services as an example while other states cover more extensive rehabilitation like a residential stay in long-term drug rehabilitation facility. If someone is involved with drug abuse and needs help, they could use their Medicaid health coverage to get this treatment. If they do not have Medicaid and also don't have enough cash or another type of medical insurance to pay for treatment, they could check if they are eligible for a Medicaid and then enroll in a drug treatment center which is approved in their state.
