"Our first goal is for 30% of all Medicare provider payments to be in alternative payment models that are tied to how well providers care for their patients, instead of how much care they provide - and to do it by 2016. Our goal would then be to get to 50% by 2018." - HHS Secretary Sylvia Burwell, HHS Blog, Jan 26, 2015.
One of the earlier steps along this road was actually the Inpatient Prospective Payment System (IPPS) itself, as it bundled payments for inpatient care episodes into Diagnosis Related Groups (DRGs). The tremendous complexity of the DRG system, however probably encouraged as much documentation and coding proliferation as it did efficient care.
The CMS Innovation Center created by the Affordable Care Act has been piloting Accountable Care Organizations (ACOs) through the Pioneer ACO model. The premise is that the value of care can be improved by incentivizing providers to decrease cost through sharing in savings (or losses) while maintaining quality. Much of what was learned from Pioneer ACOs was incorporated into the Medicare Shared Savings Program, which contains most of the Medicare ACOs today. So far very few ACOs have elected the 2-sided model (where they can earn or lose money, based on performance), selecting instead the 1-sided model where savings but not losses can be shared with the ACO. The safer 1-sided option was originally planned for only the first agreement period, and that's the model almost every system that developed an ACO chose. Even so, participation nationwide has been such that only about one tenth of the Medicare population is now covered under an ACO. Faced with the prospect of losing the vast majority of 1-sided ACOs that were not expected to renew for a second agreement under a 2-sided model, CMS proposed a new track to sweeten the deal, more favorable benchmark calculations, and agreed to allow a second term under the 1-sided model.
Separately, the CMS Innovation Center continues to trial various models to shift more risk and reward to ACOs through the Next Generation ACO. This newer ACO model allows “first dollar” shared savings or losses, rather than utilizing a minimum savings rate (MSR) or minimum loss rate (MLR) before the ACO feels any financial impact. The maximum percentage of savings or losses shared with the ACO is higher as well, potentially up to 100%. Though ACO models have previously been based on a FFS payment system or variations thereof, the Next Generation ACO model contains an option for “full capitation” for an ACO, where the ACO receives a per member per month (PBPM) payment and all providers are paid out of that amount.
