Medicaid is a type of health care insurance available for those who are in specific income brackets which qualifies them to obtain this government funded insurance. Whether or not an individual is qualified for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify simply because they make a good income. As an example, people who have a lot of dependents may qualify for Medicaid even though they earn what might certainly be a fair income. Medicaid also can cover the expense of treatment, when someone has been abusing drugs or alcohol and requires treatment. There are several alcohol and drug treatment programs which accept Medicaid, but different states have different rules for what types of treatment are covered. Certain states only cover outpatient rehabilitation services for instance while other states cover more intensive rehabilitation like a residential stay in long-term drug rehabilitation facility. If anyone is involved with substance abuse and wants help, they can use their Medicaid insurance coverage to get this treatment. If they don't have Medicaid and in addition don't have enough cash or another type of medical health insurance to pay for treatment, they could check if they are eligible for a Medicaid and then sign up for a drug rehab program that's approved in their state.
