Medicaid is a medical health insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance coverage. Whether somebody qualifies for Medicaid doesn't only determined by income however, and individuals shouldn't presume they don't qualify because they earn an acceptable income. For instance, people who have a lot of dependents may qualify for Medicaid even if they make what can certainly be a reasonable income. Medicaid also can cover the expense of rehab, if someone has been abusing alcohol or drugs and needs rehabilitation. There are lots of drug rehabilitation centers which accept Medicaid, but different states have different rules for what kinds of rehabilitation are covered. Certain states only include outpatient rehab services for example while other states cover more intensive rehabilitation like a residential stay in long-term drug treatment facility. If anyone is involved with substance abuse and wants help, they could use their Medicaid insurance coverage to get this help. If they don't have Medicaid and also don't have enough cash or another kind of medical insurance to cover rehab, they could check if they qualify for Medicaid and then enroll in an alcohol and drug rehab facility which is approved in their state.
