Medicaid is a health care insurance available for many people who are in specific income brackets which qualifies them to acquire this government provided insurance. Whether a person qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify just because they earn an acceptable income. For example, people who have many dependents may be entitled to Medicaid even when they earn what might be considered a reasonable income. Medicaid also can cover the expenses of rehabilitation, if someone has been abusing drugs or alcohol and requires treatment. There are many alcohol and drug rehab facilities which accept Medicaid, but various states have distinct rules for what forms of rehabilitation are covered. Certain states only include outpatient rehabilitation services by way of example while other states cover more extensive treatment such as a residential stay in long-term alcohol and drug rehabilitation facility. If someone is involved with drug use and needs help, they could use their Medicaid health coverage to obtain this help. If they don't have Medicaid and also don't have the funds or some other form of health insurance to pay for rehabilitation, they can determine if they are eligible for a Medicaid and then enroll in an alcohol and drug rehab center which is approved inside their state.
