Medicaid is a type of health insurance available for many people who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether an individual qualifies for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify just because they make a fair income. As an example, individuals who have a lot of dependents may be entitled to Medicaid even when they make what might be considered a reasonable income. Medicaid may also cover the expense of rehab, when someone has been abusing drugs or alcohol and needs rehab. There are numerous drug and alcohol treatment centers which accept Medicaid, but various states have distinct rules for what forms of treatment are covered. Some states only include outpatient rehabilitation services as an example while other states cover far more extensive treatment like a residential stay in long-term drug treatment facility. If anyone is involved with drug use and desires help, they could use their Medicaid health coverage to get this help. If they don't have Medicaid and in addition don't have the cash or any other form of health care insurance to cover rehabilitation, they could find out if they are eligible for a Medicaid and then sign up for an alcohol and drug rehabilitation center that's approved inside their state.
