Shaded low→high on observed fee-for-service services billed from each state · the /stats tile grid, at national scope. Shading ranks the states rather than spacing them along the range, so neighboring shades mean adjacent RANKS, not equal gaps — the key names the lowest and highest; each tile carries its own figure.

One line per state market, 51 drawn; the 4 leading states by volume are in accent, the rest are context lines. Both columns share one scale, so a slope is real change. A RATE against each state’s own fee-for-service population — assumption-free, and no all-Medicare estimate is used or implied. CY2021 is the left period because CY2020 is the pandemic year and a slope off it would read as growth almost everywhere.

Open a state market: CA · NY · TX · FL · NJ · NV · MO · OH · PA · MI · AZ · IL — the group ranking lives in the Provider groups tab. Territories bill too; the tile grid draws the 50 states and DC.
