Medicaid is a health insurance available for individuals who are in specific income brackets which qualifies them to acquire this government funded insurance. Whether or not someone is qualified for Medicaid doesn't only depend upon income however, and individuals shouldn't assume they don't qualify just because they earn a good income. For instance, people who have a lot of dependents may be eligible for Medicaid even when they earn what might be considered a sensible income. Medicaid also can cover the expenses of treatment, if someone has been abusing alcohol or drugs and requires treatment. There are lots of drug rehab programs which accept Medicaid, but different states have distinct rules for what forms of rehab are covered. Some states only cover outpatient rehab services by way of example while other states cover more extensive rehab say for example a residential stay in long-term drug and alcohol rehabilitation program. If someone is involved in substance abuse and desires help, they are able to use their Medicaid health coverage to acquire this treatment. If they do not have Medicaid and also don't have the funds or another form of medical insurance to pay for rehab, they can check if they qualify for Medicaid and then enroll in an alcohol and drug rehabilitation center that is approved inside their state.
