Medicaid is a type of medical insurance available for those who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether or not someone qualifies for Medicaid doesn't only determined by income however, and individuals shouldn't presume they don't qualify simply because they earn a fair income. For instance, people who have many dependents may be entitled to Medicaid regardless of whether they make what would be described as a fair income. Medicaid can also cover the costs of treatment, if someone has been abusing drugs or alcohol and needs rehab. There are lots of drug rehab facilities which accept Medicaid, but various states have different guidelines for what types of rehab are covered. Some states only include outpatient rehab services as an example while other states cover far more extensive treatment say for example a residential stay in long-term drug rehab program. If anyone is involved with substance abuse and needs help, they're able to use their Medicaid health coverage to get this treatment. If they do not have Medicaid plus don't have enough cash or any other form of medical insurance to pay for rehabilitation, they can find out if they qualify for Medicaid and then sign up for a drug and alcohol rehabilitation facility that is approved in their state.
