Medicaid is a type of medical insurance available for many people who are in specific income brackets which qualifies them to obtain this government funded insurance coverage. Whether or not someone qualifies for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify simply because they earn a fair income. For example, people who have quite a few dependents may qualify for Medicaid regardless of whether they earn what can be described as a reasonable income. Medicaid can also cover the costs of rehab, when someone has been abusing drugs or alcohol and requires rehab. There are lots of alcohol and drug treatment centers which accept Medicaid, but various states have different rules for what kinds of rehab are covered. Some states only cover outpatient rehab services by way of example while other states cover far more extensive rehabilitation like a residential stay in long-term drug treatment facility. If a person is involved with drug use and desires help, they're able to use their Medicaid health coverage to acquire this help. If they don't have Medicaid and also don't have enough cash or any other form of medical insurance to pay for rehabilitation, they could check if they are eligible for a Medicaid and then sign up for a drug treatment program that's approved inside their state.
