No adjustment page for 2005

The Social Security cost-of-living adjustment series and the Part B premium series do not overlap for 2005 on this site, so no combined ledger is shown rather than one being estimated.

No income-related table is committed for 2005

The Federal Register notice for 2005 states the tier percentages in prose but publishes no bracket table, and this site does not hand-key a table it could not read from a primary source. The standard premium and deductible above are primary-sourced and complete. The coverage gaps are listed in full.
