Medicaid is a type of medical insurance available for those who are in specific income brackets which qualifies them to receive this government provided insurance. Whether someone is qualified for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify because they earn a good income. For instance, men and women who have quite a few dependents may be entitled to Medicaid even if they make what can certainly be a reasonable income. Medicaid may also cover the expense of rehab, if someone has been abusing alcohol or drugs and requires rehabilitation. There are numerous alcohol and drug rehabilitation centers which accept Medicaid, but different states have different rules for what types of treatment are covered. Certain states only cover outpatient rehab services for example while other states cover far more extensive treatment like a residential stay in long-term alcohol and drug treatment program. If somebody is involved with substance abuse and desires help, they could use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid and also don't have the cash or another type of health insurance to cover rehab, they could see if they are eligible for a Medicaid and then sign up for a drug rehabilitation program which is approved inside their state.
