Medicare has announced the "Part B" premium for 2017, and for most beneficiaries it's a modest increase.

Next year's tiny Social Security cost-of-living increase means that about 70 percent of Medicare recipients will be protected from rising . For this group, the average premium will be about $109 a month.

That's about 4 percent more than the $104.90 they paid this year.

Medicare's Part B covers outpatient services such as office visits.

For the remaining beneficiaries, the average 2017 premium will be $134, or 10 percent higher.

On top of the basic premium, individual retirees making more than $85,000 and with incomes above $170,000 pay an extra surcharge. Those range to nearly $300 at the highest levels.

The Part B deductible will be $183.
