What key factor defines someone as categorically needy under Medicaid?

The key factor that defines someone as categorically needy under Medicaid is low income. Medicaid is designed to provide health coverage to individuals and families who meet certain financial criteria. The program primarily covers those with limited income, ensuring that vulnerable populations, such as low-income families, the elderly, and individuals with disabilities, have access to necessary healthcare services.

Low income is a significant determinant because it reflects the financial inability of individuals or families to afford healthcare without assistance. This criterion is critical in evaluating eligibility for Medicaid, as it serves as a primary guideline for determining who qualifies for coverage. High medical expenses, having dependent children, and ownership of property can influence eligibility in various ways, but they do not inherently define someone as categorically needy. Instead, they are part of the broader picture of financial status and how it interacts with specific state Medicaid programs and guidelines.
