Medicaid is a type of health care insurance available for those who are in certain income brackets which qualifies them to receive this government funded insurance. Whether or not someone qualifies for Medicaid doesn't only depend on their earnings however, and individuals shouldn't presume they don't qualify simply because they make a fair income. For instance, individuals who have a lot of dependents may be eligible for Medicaid even if they earn what would be considered a sensible income. Medicaid also can cover the expense of rehab, when someone has been abusing alcohol or drugs and requires rehabilitation. There are lots of drug rehab centers which accept Medicaid, but various states have distinct rules for what sorts of treatment are covered. Certain states only include outpatient rehabilitation services for example while other states cover more extensive treatment such as a residential stay in long-term drug rehabilitation program. If someone is involved in substance abuse and needs help, they're able to use their Medicaid insurance coverage to get this help. If they don't have Medicaid and in addition don't have the cash or another type of health insurance to cover rehab, they could check if they qualify for Medicaid and then enroll in a drug treatment facility that is approved within their state.
