WASHINGTON — Most Medicare beneficiaries will keep paying the same monthly premium for outpatient care next year, the Obama administration said Tuesday.

But new beneficiaries will pay a larger amount, and upper-income retirees are looking at considerably higher charges.

Separately, all beneficiaries face a $19 increase in the Part B deductible — the amount they pay for outpatient care each year before Medicare kicks in. That’s rising to $166 next year, from the current $147 — the first such increase since 2013.

The so-called “Part B” monthly premium is a well-known Medicare yardstick because it’s paid by most of the program’s 55 million beneficiaries, who generally have the money deducted from their Social Security checks.

But next year, premiums will vary for different groups of beneficiaries depending on their circumstances.

Most current beneficiaries will continue to pay $104.90, the same as this year.
