Medicaid is a type of medical insurance available for individuals who are in certain income brackets which qualifies them to receive this government provided insurance. Whether or not a person is qualified for Medicaid doesn't only depend on their earnings however, and individuals shouldn't presume they don't qualify just because they earn an acceptable income. For example, people who have a lot of dependents may qualify for Medicaid regardless of whether they earn what can certainly be a reasonable income. Medicaid may also cover the price of rehab, when someone has been abusing alcohol or drugs and needs rehab. There are many drug treatment centers which accept Medicaid, but different states have distinct rules for what forms of treatment are covered. Certain states only include outpatient rehabilitation services for example while other states cover far more extensive rehabilitation such as a residential stay in long-term drug treatment program. If someone is involved with drug abuse and desires help, they're able to use their Medicaid insurance coverage to obtain this help. If they do not have Medicaid plus don't have the funds or another kind of medical health insurance to pay for rehabilitation, they can check if they are eligible for a Medicaid and then sign up for a drug treatment facility which is approved within their state.
