Medicaid is a kind of medical insurance available for many people who are in certain income brackets which qualifies them to acquire this government provided insurance. Whether or not someone is qualified for Medicaid doesn't only depend on income however, and individuals shouldn't assume they don't qualify simply because they make an acceptable income. By way of example, individuals who have many dependents may be entitled to Medicaid even though they make what would be described as a fair income. Medicaid also can cover the costs of rehab, when someone has been abusing alcohol or drugs and requires treatment. There are lots of alcohol and drug rehabilitation facilities which accept Medicaid, but different states have different rules for what forms of rehab are covered. Some states only include outpatient rehabilitation services as an example while other states cover far more intensive rehab such as a residential stay in long-term drug and alcohol treatment facility. If someone is involved with drug abuse and desires help, they could use their Medicaid health coverage to get this treatment. If they don't have Medicaid and in addition don't have the money or any other form of medical health insurance to cover treatment, they can check if they are eligible for a Medicaid and then enroll in an alcohol and drug rehabilitation program that's approved in their state.
