Medicaid is a type of medical insurance available for individuals who are in certain income brackets which qualifies them to obtain this government provided insurance. Whether or not a person is qualified for Medicaid doesn't only depend on their earnings however, and individuals shouldn't presume they don't qualify because they earn a reasonable income. As an example, people who have quite a few dependents may be entitled to Medicaid even when they earn what can certainly be a reasonable income. Medicaid can also cover the expense of treatment, when someone has been abusing drugs or alcohol and requires treatment. There are many drug rehab centers which accept Medicaid, but various states have different guidelines for what types of rehab are covered. Certain states only cover outpatient treatment services as an example while other states cover far more extensive rehab such as a residential stay in long-term drug and alcohol treatment facility. If someone is involved in drug abuse and desires help, they can use their Medicaid health coverage to get this treatment. If they don't have Medicaid and also don't have the cash or another type of health insurance to pay for treatment, they could see if they are eligible for a Medicaid and then sign up for an alcohol and drug rehabilitation program that's approved inside their state.
