Medicaid is a kind of health care insurance available for those who are in certain income brackets which qualifies them to receive this government provided insurance. Whether somebody qualifies for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify just because they make a good income. By way of example, people who have many dependents may be eligible for Medicaid regardless of whether they make what can be considered a reasonable income. Medicaid can also cover the price of rehab, if someone has been abusing drugs or alcohol and requires rehabilitation. There are many drug and alcohol rehab programs which accept Medicaid, but different states have distinct rules for what forms of rehab are covered. Certain states only include outpatient treatment services for example while other states cover more extensive rehab such as a residential stay in long-term drug and alcohol treatment facility. If anyone is involved in drug abuse and wants help, they're able to use their Medicaid insurance coverage to get this treatment. If they do not have Medicaid and in addition don't have enough cash or any other kind of health insurance to cover rehabilitation, they can determine if they are eligible for a Medicaid and then enroll in a drug and alcohol rehabilitation center which is approved within their state.
