Medicaid is a medical insurance available for those who are in certain income brackets which qualifies them to receive this government funded insurance. Whether somebody qualifies for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify because they earn a reasonable income. As an example, people who have many dependents may qualify for Medicaid even though they earn an amount be described as a reasonable income. Medicaid can also cover the price of rehab, if a person has been abusing alcohol or drugs and needs rehab. There are several drug and alcohol treatment facilities which accept Medicaid, but different states have different guidelines for what types of rehabilitation are covered. Certain states only include outpatient rehab services for instance while other states cover more intensive rehabilitation like a residential stay in long-term drug rehabilitation facility. If someone is involved in drug abuse and wants help, they can use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid and in addition don't have enough cash or any other type of health care insurance to pay for rehab, they can find out if they are eligible for a Medicaid and then enroll in an alcohol and drug treatment program that's approved inside their state.
