Medicaid is a form of medical health insurance available for those who are in specific income brackets which qualifies them to acquire this government provided insurance. Whether an individual is qualified for Medicaid doesn't only determined by their earnings however, and individuals shouldn't presume they don't qualify because they earn a good income. For example, men and women who have quite a few dependents may qualify for Medicaid even if they earn what can be considered a reasonable income. Medicaid may also cover the costs of rehabilitation, if someone has been abusing alcohol or drugs and needs treatment. There are lots of alcohol and drug rehabilitation programs which accept Medicaid, but various states have distinct rules for what forms of rehab are covered. Some states only include outpatient rehabilitation services for example while other states cover more extensive rehab such as a residential stay in long-term drug rehab program. If a person is involved in drug use and wants help, they are able to use their Medicaid insurance coverage to obtain this treatment. If they don't have Medicaid and in addition don't have enough cash or some other kind of medical insurance to cover rehabilitation, they can determine if they qualify for Medicaid and then enroll in a drug treatment program that is approved in their state.
