Medicaid is a type of medical insurance available for those who are in certain income brackets which qualifies them to acquire this government provided insurance. Whether an individual qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they make a good income. For instance, individuals who have many dependents may qualify for Medicaid even though they earn what would be considered a reasonable income. Medicaid could also cover the expenses of rehab, if someone has been abusing drugs or alcohol and needs rehab. There are many alcohol and drug rehabilitation centers which accept Medicaid, but different states have distinct guidelines for what types of treatment are covered. Certain states only include outpatient rehab services for example while other states cover far more intensive rehabilitation say for example a residential stay in long-term alcohol and drug rehabilitation program. If anyone is involved with drug use and desires help, they're able to use their Medicaid insurance coverage to acquire this treatment. If they do not have Medicaid and also don't have the money or some other form of medical insurance to pay for rehabilitation, they can check if they are eligible for a Medicaid and then sign up for an alcohol and drug rehabilitation program which is approved inside their state.
