Medicare Part B premiums have gone up slowly over the past five years – an average of less than 2 percent a year, or $8.50 total.
CMS also noted several other changes in 2013, including:
Medicare Part A Premium:
Medicare Part A covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health care. Only about 1 percent of people with Medicare pay a premium for Part A services—you need to have paid Medicare payroll taxes for 40 quarters of employment or be married to someone who did. For those few affected, the 2013 Part A premium is decreasing to $441, down from $451 in 2012.
Medicare Part A Deductible:
This deductible is the cost to people with Medicare for up to 60 days of Medicare-covered inpatient services in the hospitals for each benefit period (a benefit period starts the day a patient is admitted and ends when the patient has been out of the hospital for 60 days in a row.) This will increase to $1,184 in 2013, up from $1156 this year (an increase of 2.4%).
Medicare Part B Deductible:
The deductible will increase to $147 in 2013, from $140. This is still $15 below the deductible in 2011.
Income-related Adjustments (IRMAA):
People with Medicare who report 2012 income above $85,000 a year ($170,000 for people filing jointly) are responsible to cover a larger portion of the cost of their Medicare Part B coverage.
These monthly Medicare Part B premium adjustments range from an additional $42.00 to an additional $230.80 (per month).
