Single-Payer (Medicare for All)
One public plan pays for everyone's covered care. Doctors and hospitals can stay private; what changes is who pays the bill. In the United States, the idea goes by Medicare for All.
In Plain Terms
Today, dozens of payers cover Americans: employer plans, marketplace plans, Medicare, Medicare AdvantageMedicare AdvantageThe private-insurer alternative to Traditional Medicare (Part C). Plans are paid a fixed, risk-adjusted amount per enrollee., Medicaid. Each has its own network, its own forms and its own prior authorizationPrior AuthorizationA health-insurance process that requires your doctor to get advance approval from your plan before it will cover a specific service, procedure, or drug. rules. Single-payer replaces them with one public payer for covered care, paid for through taxes instead of premiums.
It isn't the same as a national health service. In the U.K., the government also runs most hospitals and employs many doctors. Under single-payer, as in Canada's provincial plans, the government pays the bills but doesn't run the care.
Three Ways In, Side by Side
| Single-Payer | Public Option | Medicare Buy-In | |
|---|---|---|---|
| Private insurance | Mostly replaced for covered care | Stays; the public plan competes with it | Stays; Medicare becomes one more choice |
| Who's covered | Everyone, automatically | Whoever chooses it | Whoever is eligible and chooses it |
| How it's paid for | Taxes instead of premiums | Premiums, like other plans | Premiums paid by those who buy in |
| On the table now | Medicare for All Act, H.R. 3069 / S. 1506 | State plans in WA, CO, NV | Talarico's proposal; the on-ramp in H.R. 3069 / S. 1506 |
The goal they share is coverage for more people. They differ on how far to go and who pays. AbilityForge collects what's proposed; it's Congress's job, and the public's, to decide what works.
On the Table in Congress
The Medicare for All Act (H.R. 3069 / S. 1506), introduced April 29, 2025, by Sen. Bernie Sanders and Reps. Pramila Jayapal and Debbie Dingell. It would cover every U.S. resident with no premiums, deductibles or copays for covered care. It hasn't had a vote, and it dies January 3, 2027 unless it passes.
It phases in over four years:
- Year 1: children under 19 get full coverage; adults 55 and up can buy into Medicare.
- Year 2: the buy-in opens to 45 and up.
- Year 3: the buy-in opens to 35 and up.
- Year 4: everyone is covered under the full program.
The on-ramp is a Medicare buy-in.
Incoming: Michigan Senator-elect Abdul El-Sayed, a physician, ran on "cradle-to-grave coverage without a co-pay, a premium, or deductible." In November 2026 he told CNN he'd vote for it under any name, even "Trumpcare for all."
The Case For
One set of rules and forms, so less paperwork for doctors. No networks: see any participating doctor. No bills at the point of care. Coverage doesn't depend on your job. Some studies estimate total national health spending would fall.
The Case Against
It needs large tax increases to replace premiums. It would end most private coverage, including employer plans many people like. Lower payment rates could strain hospitals. Republicans on the House Budget Committee estimate the bill would add about $47.4 trillion to deficits from 2027 to 2036.
Whether total spending would rise or fall depends mostly on what the plan pays doctors and hospitals, which is why cost estimates vary so widely.
