The same coverage, a different price

Most household costs rise for reasons you can point at. You bought more, or the thing got more expensive.

There is a third kind, and health cover is the clearest case of it: the same coverage, at a different price, because a policy expired. Nothing about the household changed. Nothing about the plan changed. A support that was quietly holding the price down stopped.

Two of these are running at once right now, and a third mechanism decides whether income keeps up with them.

Expiry one: the enhanced marketplace premium credit

An enhanced premium tax credit for marketplace health plans expired after Congress declined to extend it, with no replacement.1

Among people re-enrolling, 80% faced higher premiums, deductibles, coinsurance or copays than the year before, and more than half said costs were "a lot" higher. Before the expiry, premiums had been estimated to roughly double on average without the credit.1

What that does downstream is the part worth reading:

That last figure is roughly one in six enrollees, and it is the one that should lead. It describes people who may lose coverage on price alone.

Expiry two: the drug plan subsidy

A federal subsidy has been holding down stand-alone prescription drug plan premiums by an average of $16 a month. It expires this year, and enrollees pay the difference from 2027.2

It arrives alongside a separate increase: the 2026 standard Part B premium rose $17.90 — the second-largest dollar increase since the program began.2

The effect is visible in how people describe their own cover. 42% of beneficiaries named at least one source of dissatisfaction, led by high premiums and then by out-of-pocket costs. About a third say out-of-pocket costs are running higher than expected.2 A separate 2026 survey found 41% dissatisfied with Medicare costs, up 10 points in a year.2

The formula that is supposed to keep up

Benefits are adjusted each year by a cost-of-living adjustment. It is worth knowing exactly how it is calculated, because it explains why the adjustment can feel wrong.

The Social Security Administration uses CPI-W. That is a price index built on the spending of urban wage earners and clerical workers. It compares the third-quarter average, July through September, against the same three months a year earlier.3

So the annual adjustment for 75.7 million recipients is set by a three-month window of an index built on a working population's basket.3 That is not the full year's inflation. It is not a retiree's spending pattern either. And health care, where these increases are landing, is a far larger share of a retiree's basket than of a wage earner's.

For 2027 two organizations estimate the adjustment at 3.6% and 3.5%. That is worth about $69.75 a month to the average beneficiary. The official figure is due in October.3

Reading the three together

Put them side by side and the structure is plain. Nobody needs to allege anything:

The costs are set by policy decisions the household had no part in, and the income is adjusted by a formula built on somebody else's shopping.

That is not a claim about intent. It is a description of two mechanisms that were designed separately and are not connected to each other.

different basket over three months.

The short version

Two health subsidies are ending at once. An enhanced marketplace premium credit has expired. That left 80% of re-enrollees facing higher costs, more than half calling them a lot higher, and 17% unsure they can afford their premium at all. A subsidy holding stand-alone drug plan premiums down by about $16 a month expires this year, and enrollees pay it from 2027. The standard Part B premium rose $17.90 alongside it — the second-largest rise ever in dollar terms. Meanwhile benefits are adjusted by a formula that reads three months of a price index built on working households, not retired ones. None of that requires bad intent to explain. It requires only that the two systems were designed apart from each other, which they were.

Sources
  1. KFF survey of 1,117 re-enrolling marketplace enrollees: 80% facing higher premiums, deductibles, coinsurance or copays than the previous year, with more than half saying costs were "a lot" higher; 73% worried about affording emergency care or hospitalization, 49% about routine care, 45% about prescriptions; 55% cutting household spending to pay for cover; 17% not confident they can afford their premium. Cause: expiry of the pandemic-era enhanced premium tax credit after Congress declined to extend it. KFF had estimated premiums would double on average without it.
  2. Expiry of a federal subsidy reducing stand-alone prescription drug plan premiums by an average of $16 a month, with enrollees paying the difference in 2027; the 2026 standard Part B premium rising $17.90, the second-largest dollar increase since the program began. eHealth survey (June): 42% of beneficiaries naming at least one dissatisfaction, led by high premiums then out-of-pocket costs, with about a third reporting out-of-pocket costs higher than expected. Senior Citizens League 2026 survey: 41% dissatisfied with Medicare costs, up 10 percentage points year on year. One contrary signal in the same coverage — self-reported monthly health spending falling from a $401–$600 band to $201–$400 — was attributed by the source to survey timing rather than treated as an improvement.
  3. Social Security Administration cost-of-living methodology: CPI-W, comparing the third-quarter (July–September) average against the same period a year earlier, with the official figure announced in October. 2027 estimates of 3.6% (The Senior Citizens League) and 3.5% (AARP), worth about $69.75 a month to the average beneficiary. 75.7 million Americans receive benefits. ---
