Reducing Medicaid coverage by removing people from the program is expected to increase overall health care costs due to more uninsured individuals, higher uncompensated care, and cost-shifting to insured populations.
Throwing people off Medicaid is going to increase health care costs for everyone.

What the Evidence Shows
The claim that throwing people off Medicaid will increase health care costs for everyone involves several interconnected components: first, that Medicaid cuts lead to more uninsured individuals; second, that increased uninsured rates result in more uncompensated care; and third, that uncompensated care drives up costs for insured patients and the health system overall. Evidence from multiple recent analyses and expert sources supports these links.

Additionally, reduced Medicaid funding strains hospital finances and can lead to service cutbacks or closures, further destabilizing local health care access and increasing costs. While some sources with conservative perspectives question the scale of coverage losses, the consensus among nonpartisan budget analysts and public health experts is that Medicaid cuts will have broad cost-increasing effects.
The causal mechanism is plausible and supported by historical data on uncompensated care cost-shifting. However, exact magnitudes depend on policy details and state responses.
Therefore, the claim is largely accurate but could benefit from nuance regarding scale and timing.
