By law, the Centers for Medicare & Medicaid Services (CMS) is required to announce the Part A deductibles and Part B premium amounts, a notice that is published annually in the Federal Register.
Most Medicare beneficiaries will not see a Part B monthly premium increase as a result of a "hold harmless" provision in the current law.
This allows for 73 percent of beneficiaries to be protected from an increase raising the 2010 Part B monthly premiums from $96.40 to $110.50.
