Medicaid is a medical insurance available for those who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether or not someone 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. As an example, men and women who have many dependents may be eligible for Medicaid regardless of whether they make what would be described as a sensible income. Medicaid may also cover the expense of rehabilitation, if a person has been abusing alcohol or drugs and requires rehab. There are many alcohol and drug treatment centers which accept Medicaid, but different states have distinct guidelines for what kinds of treatment are covered. Certain states only cover outpatient rehab services for instance while other states cover far more intensive rehab like a residential stay in long-term alcohol and drug treatment program. If a person is involved in drug use and desires help, they are able to use their Medicaid health coverage to acquire this help. If they don't have Medicaid and in addition don't have the funds or any other kind of health care insurance to pay for treatment, they could find out if they are eligible for a Medicaid and then enroll in an alcohol and drug treatment center that's approved inside their state.
