The grouper, out of the black box.

This sandbox runs the real MS-DRG grouping logic in force today (v44) and the IPPS rates for the discharge date (FY2027; FY2026 for earlier discharges), live: toggle a diagnosis on or off and watch the decision path, the DRG and the payment re-run.

      Reading the result

      Documentation note: severity should reflect conditions clinically present and documented; this sandbox is for understanding payment mechanics, not for inflating severity. Real MS-DRG v44 grouping tables and IPPS rates for the discharge date (FY2027; FY2026 for earlier discharges) — the same engine as the calculator, checked against the official pricer to within a dollar.
