WASHINGTON (AP) — Medicare premiums are going up $5 a month in 2013, the government said Friday. It's less than expected, but still enough to eat up about one-fourth of a typical retiree's cost-of-living raise next year.

Medicare chief Marilyn Tavenner said the new "Part B" premium for outpatient care will be $104.90 a month. In most cases, it's deducted directly from a beneficiary's monthly Social Security check. Currently the premium is $99.90 a month.

Earlier this year, the government projected an increase of as much as $9 for 2013, but health care inflation has remained modest.

Still, advocates for the elderly didn't see much to cheer about, particularly since Medicare cuts are on the table in budget negotiations between President Barack Obama and Republicans in Congress. Obama has promised to protect beneficiaries, but even his plan calls for upper-income retirees to pay more.

"These increases aren't as big as projected, but they are still increases," said Joe Baker, president of the Medicare Rights Center, a New York-based advocacy group. "Our fear is that as policymakers discuss deficit reduction, they'll pile even more costs on to seniors."

High-income beneficiaries, those making above $85,000 a year individually or $170,000 for a couple, will face bigger increases. They will pay an additional $42 to $230.80 a month, depending on income. Most low-income beneficiaries have their premiums paid by Medicaid.

Tavenner also announced that Medicare's hospitalization deductible will increase by $28, to $1,184. The deductible is the amount a person must pay before health insurance kicks in. Many seniors have some form of additional coverage to handle their Medicare hospital deductible.

The annual deductible for outpatient care will increase by $7, to $147. Continued...
