In most states, qualifying for SSI automatically qualifies you for Medicaid. This is one of the most valuable parts of SSI.
States with Automatic Medicaid: In the majority of states, your SSI approval = Medicaid approval. No separate application needed.
209(b) States (separate Medicaid application required): Connecticut, Hawaii, Illinois, Indiana, Minnesota, Missouri, New Hampshire, North Dakota, Ohio, Oklahoma, and Virginia use their own eligibility criteria. You may need to apply separately, but the income limits are often higher than SSI limits.
Medicaid covers a lot
Doctor visits, hospital stays, prescriptions, mental health services, dental (in many states), vision, and long-term care. This coverage alone can be worth thousands of dollars per year.
