Legacy pricers take codes in and spit an MS-DRG out — they never show how close you were to a different tier. This sandbox runs the real v43.1 grouping logic and the real FY2026 payment, live: toggle a diagnosis on or off and watch the decision path, the DRG, and the dollars move.
Each chip shows its real CC/MCC classification once grouped.
Real v43.1 grouping tables and FY2026 IPPS rates — the same engine as the calculator, which reconciles with the official pricer to the dollar. Documentation note: severity should reflect conditions clinically present and documented; this sandbox is for understanding payment mechanics, not for inflating severity.
