Medicaid is a health care insurance available for individuals who are in certain income brackets which qualifies them to obtain this government provided insurance. Whether someone qualifies for Medicaid doesn't only determined by income however, and individuals shouldn't presume they don't qualify just because they make a reasonable income. For example, people who have many dependents may be eligible for Medicaid regardless of whether they earn what might certainly be a sensible income. Medicaid could also cover the expense of rehab, if someone has been abusing drugs or alcohol and requires treatment. There are lots of drug treatment facilities which accept Medicaid, but various states have different rules for what forms of treatment are covered. Certain states only cover outpatient rehabilitation services for example while other states cover more intensive rehab say for example a residential stay in long-term drug and alcohol rehab center. If somebody is involved with substance abuse and desires help, they could use their Medicaid health coverage to obtain this treatment. If they do not have Medicaid and also don't have the money or any other form of medical health insurance to cover rehab, they could check if they are eligible for a Medicaid and then enroll in a drug rehabilitation facility that is approved inside their state.
