Medicaid is a medical insurance available for individuals who are in specific income brackets which qualifies them to receive this government provided insurance. Whether somebody is qualified for Medicaid doesn't only depend on income however, and individuals shouldn't presume they don't qualify because they earn an acceptable income. As an example, people who have quite a few dependents may be entitled to Medicaid even when they earn what might be considered a sensible income. Medicaid can also cover the expense of rehab, when someone has been abusing alcohol or drugs and requires treatment. There are several drug and alcohol treatment centers which accept Medicaid, but various states have different guidelines for what forms of treatment are covered. Certain states only include outpatient rehab services for example while other states cover far more extensive rehabilitation say for example a residential stay in long-term alcohol and drug treatment program. If anyone is involved with drug abuse and wants help, they are able to use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid and also don't have enough cash or some other kind of health care insurance to cover rehab, they could check if they qualify for Medicaid and then enroll in a drug and alcohol rehabilitation facility that is approved inside their state.
