The stars will position MetroPlusHealth, a subsidiary of NYC Health and Hospitals, to be awarded additional funding through the Medicare Advantage quality bonus program established by the Affordable Care Act. President and CEO of MetroPlusHealth Dr. Talya Schwartz said in a statement that the ratings boost was a “significant achievement.” CMS assigns Medicare Advantage plans star ratings on a five-star scale based on measures including quality of care, member experience and health plan performance. Medicare Advantage Plans that gain a rating of four stars or higher unlock access to additional Medicare funding as an incentive to provide better service. But with additional funding so closely tied to ratings, Medicare Advantage organizations have taken to filing lawsuits over low ratings.
