Hospitals' latest proposed payment rule from CMS should give them extra incentive to improve their relationship with home care providers. That's because under the proposal, their pay will be docked for some hospital readmissions starting in October 2012. The rule proposes "a Hospital Readmissions Reduction Program that will reduce payments beginning in FY 2013 to certain hospitals that have excess readmissions ... for three conditions -- acute myocardial infarction (or heart attack), heart failure, and pneumonia," CMS says in a release. The program is required by the Affordable Care Act passed last year. CMS will take comments on the proposed rule until June 20 and will publish a final rule by Aug. 1, it says.
