On December 16, 2020, the Centers for Medicare and Medicaid Services (CMS) published its annual report on National Health Expenditures and its NHE Tables includes data on Medicaid from 1966 to 2019. On December 16, 2020, usgovernmentspending.com updated its Medicaid data.
| Item | 2019 Estimate | 2019 Actual |
| Federal Medicaid | $409.4 bn | $409.4 bn |
| State Medicaid (net) | $219.1 bn | $204.1 bn |
| Total Medicaid | $628.5 bn | $613.5 bn |
The federal Medicaid number comes from the Federal Budget Subfunction 558: Grants to states for Medicaid. The state contribution comes from the NHE Tables.
usgovernmentspending.com publishes "guesstimates" of state and local spending from the latest year published by the Census Bureau (currently FY 2018) to the last year in the Historical Tables of the federal budget (for the FY 2021 budget that is 2025). So we have developed "guesstimates" of Medicaid spending going out to 2025, assuming that the overall Medicaid spending increases at the same rate as the federal "Grants to States for Medicaid" increases.
National Health Expenditure data is updated each year in mid December.
