Medicaid is a form of health insurance available for those who are in specific income brackets which qualifies them to acquire this government funded insurance. Whether or not a person qualifies for Medicaid doesn't only depend on their earnings however, and individuals shouldn't presume they don't qualify because they make a good income. As an example, people who have quite a few dependents may be eligible for Medicaid regardless of whether they earn what can be described as a sensible income. Medicaid also can cover the expenses of treatment, if someone has been abusing drugs or alcohol and requires treatment. There are lots of alcohol and drug treatment programs which accept Medicaid, but different states have different guidelines for what types of rehab are covered. Certain states only cover outpatient rehabilitation services for instance while other states cover far more extensive rehabilitation say for example a residential stay in long-term alcohol and drug rehab facility. If someone is involved with drug abuse and needs help, they're able to use their Medicaid health coverage to obtain this treatment. If they do not have Medicaid and also don't have enough cash or another form of health care insurance to cover rehabilitation, they could find out if they qualify for Medicaid and then sign up for a drug rehabilitation center that's approved inside their state.
