CMS published Change Request 9648 on July 15, 2016 with the updates for FY 2014 SSI percentages (https://www.cms.gov/Regulations-and-Guidance/Guidance/Transmittals/Downloads/R1681OTN.pdf). There are links within the change request for the ratios for the IPPS Hospitals, Inpatient Rehabilitations Facilities, and the Long Term Care Hospitals.
Additionally, this change request provides guidance for accepting FY 2014 amended cost reports for hospitals requesting to revise the worksheet S-10 as the CMS FY 17 proposed rule indicates that they will begin using worksheet S-10 to determine uncompensated care payments starting in FY 2018. In order for the revised information to be considered for the FY 18 computations, amended cost reports must be received by the MAC by September 30, 2016. Submissions for data revisions to FY 14 cost reports received on or after October 1, 2016 will not be accepted
