This bill amends the Pathway for SGR Reform Act of 2013 to specify that certain provisions of current law regarding the calculation of hospital length of stay apply to certain long-term care hospitals (LTCHs) that are permitted, under Medicare, to establish new LTCHs or increase LTCH beds. Specifically, with respect to such LTCHs, two types of patients shall be excluded from the calculation of LTCH length of stay under Medicare: (1) those for whom payment is made under a Medicare Advantage plan, and (2) those for whom payment is made at the site-neutral payment rate.
