Medicaid is a health care insurance available for many people who are in specific income brackets which qualifies them to receive this government provided insurance. Whether or not a person is qualified for Medicaid doesn't only depend upon income however, and individuals shouldn't assume they don't qualify just because they make a good income. For example, people who have a lot of dependents may be entitled to Medicaid even when they earn what might be considered a fair income. Medicaid can also cover the price of treatment, if someone has been abusing alcohol or drugs and requires rehabilitation. There are lots of drug rehabilitation centers which accept Medicaid, but different states have distinct guidelines for what kinds of rehab are covered. Certain states only include outpatient rehab services for instance while other states cover far more extensive treatment like a residential stay in long-term drug and alcohol rehab facility. If somebody is involved in substance abuse and needs help, they are able to use their Medicaid insurance coverage to obtain this help. If they don't have Medicaid and also don't have enough cash or some other type of medical insurance to cover treatment, they can see if they qualify for Medicaid and then enroll in an alcohol and drug treatment program that is approved inside their state.
