Medicaid is a type of medical health insurance available for individuals who are in certain income brackets which qualifies them to obtain this government funded insurance coverage. Whether or not somebody is qualified for Medicaid doesn't only depend upon income however, and people 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 though they make what would certainly be a reasonable income. Medicaid could also cover the expenses of rehabilitation, if someone has been abusing alcohol or drugs and requires treatment. There are lots of drug and alcohol rehabilitation facilities which accept Medicaid, but different states have distinct rules for what forms of rehab are covered. Certain states only include outpatient rehabilitation services for instance while other states cover more extensive treatment such as a residential stay in long-term drug rehab program. If someone is involved with substance abuse and needs help, they can use their Medicaid insurance coverage to obtain this treatment. If they do not have Medicaid and in addition don't have the money or any other kind of health care insurance to pay for rehabilitation, they could check if they qualify for Medicaid and then enroll in an alcohol and drug rehabilitation program which is approved in their state.
