Medicaid is a type of medical insurance available for individuals who are in specific income brackets which qualifies them to receive this government provided insurance. Whether somebody qualifies for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify because they make a reasonable income. For example, people who have quite a few dependents may be eligible for Medicaid even when they earn what can be described as a sensible income. Medicaid could also cover the expenses of rehab, if a person has been abusing alcohol or drugs and needs rehab. There are numerous drug and alcohol rehabilitation centers which accept Medicaid, but various states have different rules for what forms of rehabilitation are covered. Certain states only include outpatient treatment services as an example while other states cover more extensive treatment say for example a residential stay in long-term drug treatment program. If someone is involved in drug abuse and needs help, they're able to use their Medicaid health coverage to acquire this help. If they do not have Medicaid and also don't have the funds or another form of health care insurance to cover treatment, they can check if they qualify for Medicaid and then sign up for a drug rehab program which is approved within their state.
