Dollar amounts come from the separate CMS “QPA and Offers” file: line items decided for the provider or the plan with a non-suppressed QPA and prevailing offer. That file cannot be joined to the line items above, so its n differs. Awarded = the prevailing (selected) offer; it is not a record of what was paid. State comes from the file’s geographic region; a metro area that spans states counts in each. How the dollar figures work
