What is the per discharge adjustment?

CMS applies a per discharge adjustment to payments to an LTCH when admissions to that LTCH from a single referring hospital exceed a threshold during a single cost reporting period (usually 25%, but up to 50% under rural or MSA-dominant exceptions). This adjustment was first implemented in the FY2005 IPPS final rule and is known as the “25-percent threshold policy”. The policy seeks to limit incentives for acute care hospitals and LTCHs to join up in pairs to split a single episode of care into separate acute hospital and LTCH stays. Some LTCHs are statutorily exempt from the threshold adjustment, and full implementation of regulatory changes to expand the threshold to most LTCHs has been statutorily delayed. The most recent delay is set to expire at the end of FY 2016 reporting periods. Anticipating that expiration, CMS now proposes to create a new, unified “25-percent threshold policy” through a combination of actions that incorporate many of the existing policy provisions:

When will CMS use S-10 data?

CMS proposes to begin incorporating the use of Worksheet S-10 data to calculate uncompensated care payments in FY 2018.

CMS will use 1-year of Worksheet S-10 data in FY 2018, 2 years in FY 2019, and by 2020 and subsequent years will use 3 years of Worksheet S-10 data to calculate Factor 3.

What is uncompensated care?
