Medicaid is a medical insurance available for many people 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 their earnings however, and people shouldn't presume they don't qualify simply because they earn a reasonable income. For example, men and women who have quite a few dependents may be entitled to Medicaid regardless of whether they make what can be considered a fair income. Medicaid can also cover the costs of rehab, if someone has been abusing alcohol or drugs and needs rehab. There are several drug treatment facilities which accept Medicaid, but different states have distinct rules for what kinds of treatment are covered. Certain states only cover outpatient rehabilitation services as an example while other states cover more extensive rehab such as a residential stay in long-term drug and alcohol rehab facility. If anyone is involved with drug abuse and desires help, they can use their Medicaid health coverage to obtain this help. If they do not have Medicaid and in addition don't have the money or another type of medical insurance to cover rehabilitation, they could find out if they qualify for Medicaid and then sign up for an alcohol and drug treatment facility that is approved within their state.
