I run a YC startup that was accepted to Medicare ACCESS.
Historically, insurance has paid for activity: time spent in visits, RVUs generated, and minutes logged. This was a reasonable starting point, but the flaw is that there's no strong incentives to be efficient.
ACCESS is explicitly a "deflationary" approach. Medicare has set the payment rates high enough to be viable for startups, but low enough that you have to use software (including AI) to deliver a large part of your program.
So Medicare has basically created economic incentives to reward software without prescribing the exact shape of the programs. I thought it was a really interesting approach and builds on 15 years of lessons from CMMI (Medicare's innovation group).
Why isn't this vulnerable to the upcoding problem that plagues medicare advantage plans?
I would maybe modify this to say - there is a strong incentive to be efficient - you only make so much money per encounter, DRG visit to the hospital, etc. So the pressure from "management" on a lot of us clinicians is to see more people per day, make each hospital visit as short as possible, etc. Medicaid providers now see something like 50-60 patients a day because the per-patient visit is relatively low. But there isn't as much incentive for outcomes. I think CMS has tried it in the past, but with varying success. Whether this new mousetrap will work, who knows.
