Several big named health systems that were expected to become Pioneer ACOs have declined to apply, according to Kaiser Health News.
The article states that Mayo Clinic, the Cleveland Clinic, Geisinger Health System and Intermountain Healthcare were thought to be promising models for ACOs. ACO rules, which were released in March, were met with resistance from providers across the country, citing high financial risk and rigid reporting requirements.
In response, CMS announced an alternative for health systems who were already on track to becoming an ACO, called the Pioneer ACO program. This program offered higher cost savings for high performing health systems. CMS has not announced how many health systems applied for the Pioneer ACO program.
