Medicaid is a form of health care insurance available for many people who are in specific income brackets which qualifies them to receive this government provided insurance. Whether or not a person qualifies for Medicaid doesn't only depend on their earnings however, and people shouldn't presume they don't qualify simply because they make a fair income. For instance, men and women who have many dependents may be entitled to Medicaid even if they earn what would be described as a fair income. Medicaid can also cover the costs of treatment, when someone has been abusing alcohol or drugs and requires rehabilitation. There are numerous drug rehabilitation programs which accept Medicaid, but different states have different guidelines for what sorts of rehabilitation are covered. Some states only include outpatient treatment services for example while other states cover more intensive treatment like a residential stay in long-term alcohol and drug treatment program. If anyone is involved in drug abuse and wants help, they could use their Medicaid insurance coverage to obtain this help. If they do not have Medicaid and in addition don't have the money or another kind of health care insurance to pay for rehab, they could check if they are eligible for a Medicaid and then enroll in an alcohol and drug rehabilitation facility which is approved inside their state.
