Medicaid is a health care insurance available for individuals who are in specific income brackets which qualifies them to acquire this government funded insurance. Whether or not someone is qualified for Medicaid doesn't only determined by their earnings however, and people shouldn't assume they don't qualify just because they earn a good income. For instance, individuals who have many dependents may be entitled to Medicaid even when they make what might be considered a sensible income. Medicaid can also cover the expenses of rehabilitation, if a person has been abusing alcohol or drugs and needs rehab. There are many alcohol and drug treatment centers which accept Medicaid, but different states have different rules for what sorts of rehabilitation are covered. Certain states only cover outpatient treatment services as an example while other states cover more intensive rehabilitation like a residential stay in long-term drug and alcohol rehab program. If somebody is involved with substance abuse and needs help, they could use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid plus don't have the cash or some other form of health insurance to pay for rehabilitation, they could see if they are eligible for a Medicaid and then sign up for a drug treatment center that is approved inside their state.
