Medicare open enrollment runs through December 7, and the headline number for 2025 is already landing with a thud.
The standard Part B premium is rising to $185 a month, up about $10.30 from $174.70 in 2024.
That's roughly a 6% jump, and it lands on top of the annual deductible, which climbs from $240 to $257.
For anyone living on a fixed income, that's not a rounding error.
Part B premiums are typically deducted straight from Social Security checks, so the increase shows up automatically — no action required, no way to opt out.
If your cost-of-living adjustment doesn't keep pace, the net gain in your monthly check can shrink or vanish entirely.
Here's the part that rarely makes headlines: most people pay the standard premium, but higher earners pay more.
If your modified adjusted gross income tops $106,000 as an individual or $212,000 as a couple, you're in the income-related monthly adjustment amount, or IRMAA.
Those surcharges stack on top of the base premium, and they're based on tax returns from two years prior — meaning your 2025 rate reflects your 2023 income.
A one-time bump from selling a house or cashing out investments can trigger a surcharge you didn't see coming.
If your income dropped because of a specific life-changing event — retirement, divorce, death of a spouse, loss of a pension — you can file Form SSA-44 and ask Social Security to use your current income instead.
It's not automatic, and it requires documentation, but it's real and underused.
Part B covers doctor visits, outpatient care, and preventive services, and its costs are tied to overall health care spending, which keeps climbing.
The program's trustees have warned for years that the trust fund backing Part A hospital coverage faces a projected shortfall in the 2030s.
That's the long-term squeeze behind the short-term premium bump.
Every fall, ads flood the airwaves promising to "eliminate" your Medicare costs or bundle everything into one zero-premium plan.
Some Medicare Advantage plans do carry $0 premiums, but that doesn't mean free — you're often trading provider networks, prior authorizations, and copays for that headline number.
Read the summary of benefits, not the commercial.
The practical move: check your current coverage against what's available in your ZIP code during open enrollment, and don't assume your plan's drug formulary or network stayed the same.
If you're in original Medicare and want drug coverage, you need a standalone Part D plan or a Medicare Advantage plan that includes it — there's no default.
Also worth noting: if you're still working past 65 and covered by an employer plan, you may be able to delay Part B and avoid the premium and any late-enrollment penalty.
But that depends on employer size and plan type, so verify before assuming.
Our take: the annual premium increase is easy to ignore until it's quietly eating your Social Security increase.
Treat open enrollment as a mandatory annual audit, not a formality.

Five minutes on Medicare's plan finder can be worth more than most financial advice you'll pay for.
