Medicaid is a form of medical health insurance available for individuals who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether an individual qualifies for Medicaid doesn't only depend on income however, and individuals shouldn't assume they don't qualify just because they earn a good income. For instance, individuals who have many dependents may be entitled to Medicaid even when they earn what would be considered a fair income. Medicaid could also cover the expenses of rehabilitation, if a person has been abusing drugs or alcohol and requires rehabilitation. There are lots of drug rehab programs which accept Medicaid, but various states have distinct guidelines for what kinds of rehabilitation are covered. Certain states only cover outpatient rehabilitation services for example while other states cover far more intensive rehab like a residential stay in long-term drug and alcohol rehab program. If anyone is involved with substance abuse and needs help, they can use their Medicaid insurance coverage to obtain this treatment. If they don't have Medicaid plus don't have enough cash or some other type of medical insurance to cover rehabilitation, they can check if they qualify for Medicaid and then sign up for an alcohol and drug rehab program that's approved inside their state.
