Medicaid is a type of medical health insurance available for those who are in specific income brackets which qualifies them to acquire this government funded insurance coverage. Whether somebody is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't presume they don't qualify just because they make an acceptable income. For example, men and women who have a lot of dependents may be entitled to Medicaid even if they make what would be considered a fair income. Medicaid may also cover the expense of treatment, if a person has been abusing drugs or alcohol and needs rehabilitation. There are numerous drug and alcohol treatment programs which accept Medicaid, but various states have distinct rules for what types of rehab are covered. Some states only cover outpatient treatment services for instance while other states cover far more intensive rehabilitation like a residential stay in long-term drug treatment center. If anyone is involved in substance abuse and wants help, they could use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid plus don't have enough cash or some other kind of medical insurance to pay for rehabilitation, they can find out if they qualify for Medicaid and then sign up for a drug and alcohol treatment program that is approved inside their state.
