Medicare IPPS Payment Decomposition

Compare how Medicare pays different hospitals for the same inpatient claim

Pick a DRG (the inpatient diagnosis-related group) and one or more hospitals. We'll show how Medicare's IPPS payment breaks down into base, IME (teaching), DSH (disproportionate share), capital, uncompensated care, and quality adjustments. Hospital data is from the CMS FY 2026 IPPS Final Rule Impact File.
