CMS Pub. 100-01, ch. 3, § 20.6

Part B Premium

activein force · 2026-08-25 – presentas-observed

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.
