Medicaid is a kind of medical health insurance available for individuals who are in specific income brackets which qualifies them to receive this government funded insurance coverage. Whether someone is qualified for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify just because they earn an acceptable income. For example, individuals who have a lot of dependents may be eligible for Medicaid regardless of whether they earn what would be described as a reasonable income. Medicaid also can cover the costs of rehabilitation, if a person has been abusing alcohol or drugs and requires treatment. There are numerous drug rehab centers which accept Medicaid, but various states have different guidelines for what kinds of treatment are covered. Certain states only cover outpatient rehabilitation services for instance while other states cover far more extensive treatment like a residential stay in long-term drug treatment facility. If someone is involved with drug use and needs help, they can use their Medicaid insurance coverage to obtain this treatment. If they do not have Medicaid and also don't have enough cash or another form of health care insurance to pay for treatment, they can find out if they are eligible for a Medicaid and then sign up for a drug and alcohol rehabilitation center that is approved in their state.
