Medicaid is a type of health care insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance. Whether or not an individual is qualified for Medicaid doesn't only determined by their earnings however, and people shouldn't presume they don't qualify simply because they earn a reasonable income. As an example, people who have many dependents may be eligible for Medicaid even if they make what might be described as a reasonable income. Medicaid could also cover the expenses of treatment, if a person has been abusing alcohol or drugs and requires rehabilitation. There are lots of drug and alcohol rehabilitation facilities which accept Medicaid, but various states have distinct rules for what forms of treatment are covered. Some states only cover outpatient treatment services as an example while other states cover far more intensive rehabilitation say for example a residential stay in long-term alcohol and drug treatment program. If someone is involved in substance abuse and desires help, they could use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid plus don't have the money or some other type of medical health insurance to cover rehabilitation, they can find out if they qualify for Medicaid and then enroll in a drug and alcohol rehabilitation facility that is approved inside their state.
