Medicaid is a form of health care insurance available for those who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether someone qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't presume they don't qualify because they earn a good income. For example, people who have many dependents may be eligible for Medicaid regardless of whether they make what would be considered a fair income. Medicaid also can cover the price of rehab, when someone has been abusing alcohol or drugs and requires treatment. There are many alcohol and drug treatment programs which accept Medicaid, but different states have distinct rules for what sorts of treatment are covered. Certain states only include outpatient treatment services as an example while other states cover far more intensive rehab such as a residential stay in long-term alcohol and drug rehabilitation program. If someone is involved with substance abuse and wants help, they can use their Medicaid insurance coverage to acquire this help. If they do not have Medicaid and also don't have the money or another kind of health care insurance to pay for rehab, they could determine if they are eligible for a Medicaid and then enroll in a drug treatment program which is approved within their state.
