CMS Pub. 100-01, ch. 3, § 20.6
Part B Premium
The Centers for Medicare and Medicaid Services (CMS) updates the Part B premium
each year. These adjustments are made according to formulas set by statute. By law,
the monthly Part B premium must be sufficient to cover 25 percent of the program’s
costs, including the costs of maintaining a reserve against unexpected spending
increases. The federal government pays the remaining 75 percent.
Below are the annual Part B premium amounts from Calendar Year (CY) 1996 to 2006.
For these years, and years prior to 1996, the Part B premium is a single established rate
for all beneficiaries.
Year Part B Premium
1996 $42.50
1997 $43.80
1998 $43.80
1999 $45.50
2000 $45.50
2001 $50.00
2002 $54.00
2003 $58.70
2004 $66.60
2005 $78.20
2006 $88.50
Beginning on January 1, 2007, the Part B premium is based on the income of the
beneficiary. See the following Change Requests (CRs) for more information.
