Medicaid is a medical health insurance available for individuals who are in certain income brackets which qualifies them to receive this government provided insurance coverage. Whether someone is qualified for Medicaid doesn't only determined by income however, and people shouldn't presume they don't qualify just because they make a good income. For example, individuals who have many dependents may be entitled to Medicaid even when they make what would be described as a reasonable income. Medicaid can also cover the expenses of rehabilitation, if someone has been abusing alcohol or drugs and requires treatment. There are numerous alcohol and drug rehab centers which accept Medicaid, but various states have different guidelines for what sorts of treatment are covered. Some states only cover outpatient rehabilitation services for example while other states cover far more extensive treatment like a residential stay in long-term drug rehabilitation program. If somebody is involved with substance abuse and desires help, they're able to use their Medicaid health coverage to obtain this treatment. If they do not have Medicaid and in addition don't have the funds or some other form of medical health insurance to cover rehabilitation, they could check if they are eligible for a Medicaid and then sign up for a drug rehab center that is approved inside their state.
