For example, people who have a lot of dependents may qualify for Medicaid even when they earn an amount certainly be a reasonable income. Medicaid may also cover the expenses of treatment, if someone has been abusing alcohol or drugs and requires rehab. There are several alcohol and drug rehabilitation facilities which accept Medicaid, but various states have distinct rules for what forms of rehab are covered. Certain states only include outpatient rehabilitation services for example while other states cover more extensive treatment such as a residential stay in long-term drug and alcohol rehabilitation program. If someone is involved with drug use and desires help, they could use their Medicaid health coverage to acquire this help. If they don't have Medicaid and in addition don't have enough cash or any other type of health insurance to pay for treatment, they can find out if they are eligible for a Medicaid and then enroll in an alcohol and drug rehab facility which is approved within their state.
