Methodology for Development of Market Baskets

Links to Federal Register for Current Market Baskets

  • The current market baskets for each of the Prospective Payment Systems (PPSs) were proposed and finalized in rulemaking.  In the Related Links section below, we provide the links to the PPS final rules published in the Federal Register for each of the following market baskets (with page references):
    • 2018-based Inpatient Prospective Payment System (IPPS) market basket effective for FY 2022 (page 45194) 
    • 2018-based Capital Input Price Index (CIPI) effective for FY 2022 (page 45208) 
    • 2018-based Skilled Nursing Facilities (SNF) market basket effective for FY 2023 (page 42444) 
    • 2021-based Home Health (HH) market basket effective for CY 2024 (page 77726)
    • 2021-based Inpatient Rehabilitation Facilities (IRF) market basket effective for FY 2024 (page 50966)
    • 2021-based Inpatient Psychiatric Facilities (IPF) market basket effective for FY 2024 (page 51057)
    • 2017-based Long-term Care Hospital (LTCH) market basket effective for FY 2021 (page 58909)

Illustrative Example of Market Basket Calculations (as described in IPPS FY 2010 Proposed Rule)

  • In an effort to provide greater transparency of how CMS market baskets are constructed, the zip file in the Downloads section below provides 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
