Medicaid is a kind of medical insurance available for many people who are in certain income brackets which qualifies them to acquire this government provided insurance. Whether someone qualifies for Medicaid doesn't only determined by their earnings however, and people shouldn't presume they don't qualify simply because they make an acceptable income. For example, people who have a lot of dependents may qualify for Medicaid even though they earn what might be considered a reasonable income. Medicaid also can cover the expenses of rehabilitation, if someone has been abusing alcohol or drugs and needs treatment. There are lots of alcohol and drug rehabilitation centers which accept Medicaid, but various states have distinct rules for what types of rehab are covered. Certain states only include outpatient rehab services as an example while other states cover far more intensive rehabilitation such as a residential stay in long-term drug and alcohol rehabilitation facility. If someone is involved with drug use and needs help, they can use their Medicaid health coverage to obtain this help. If they don't have Medicaid plus don't have the money or another form of medical health insurance to cover treatment, they can determine if they qualify for Medicaid and then sign up for an alcohol and drug rehabilitation center which is approved inside their state.
