FY2023 IPPS Proposed Changes

CMS is proposing to limit any major changes to MS-DRG designations and changes. The proposed rule does not include any NEW MS-DRGs for FY2023.

Only new codes were added or amended to the CC/MCC lists (35 codes)
CMS is considering numerous changes to quality reporting and value programs, according to the FY2023 IPPS proposed rule. The proposed rule would remove penalties under the Hospital-Acquired Condition Reduction Program (HACRP) and apply a neutral payment adjustment under the Hospital Value-Based Purchasing Program for FY 2023 due to proposals to suppress measures in the programs to address continuing impacts of the COVID-19 PHE.
CMS is proposing 3.2% increase for hospitals participating in EHR and IQR program. This reflects the projected hospital market basket update of 3.1%, reduced by a 0.4 percentage point productivity adjustment, and increased by a 0.5 percentage point for a statutorily required documentation and coding adjustment. The proposed increase in operating and capital IPPS payment rates, partially offset by decreases in outlier payments for extraordinarily high-cost cases, will generally increase hospitals’ payments in FY 2023 by $1.6 billion.
For New Technology Payments, CMS proposed that beginning FY 2024, completed applications for NTAP would be publicly posted online. The CMS also proposed to use National Drug Codes instead of ICD-10-PCS Section “X” codes to identify cases involving the use of therapeutic agents approved for NTAPs beginning with a transitional period in FY 2023.
Comments are due June 17, 2023.
