Market Basket Information

Definitions and general information.

  • In an effort to provide greater transparency of how CMS market baskets are constructed, we are posting three illustrative documents as described in the CMS Proposed Rule:  "Medicare Program; Proposed Changes to the Hospital Inpatient Prospective Payment Systems for Acute Care Hospitals and Fiscal Year 2010 Rates and to the Long-Term Care Hospital Prospective Payment System and Rate Year 2010 Rates."  These electronic files demonstrate:
    • How the detailed cost weights for the proposed 2006-based IPPS operating market basket are determined using the 2002 Benchmark Input-Output data
    • How vintage weights are calculated for the 2006-based Capital Input Price Index
    • How vintage weights are applied to raw price proxies to calculate a vintage-weighted price proxy for the 2006-based Capital Input Price Index
  • The “MFP Methodology” document provides an overview of the methodology used to produce a forecast of private nonfarm business multifactor productivity, as well as the proxy variables used in the current forecast model.
