CMS announced on January 5, 2012 that it extended the application deadline for Models 2-4 under the Bundled Payment for Care Improvement Initiative to April 30, 2012. Under the Bundled Payment Initiative, providers propose a set price for a single episode of care and then receive a predetermined discount if the target is met. Providers may still apply for Models 2, 3 and 4:

- Model 2: retrospective acute care stays along with post acute care

- Model 3: retrospective post acute care

- Model 4: prospective acute care hospital stays
