City totals are cut from the same public CMS data as everything above: Medicare fee-for-service only, after CMS's under-11-beneficiary suppression, dollars always est. Medicare paid. Where a city shows fewer than 3 billers, we show the totals and name no one. Naming is capped by design: up to 5 ranked billers above plus at most one leader per city here, and no one else on this page.
