42 CFR § 403.754
Monitoring expenditure level
June 11, 2020
(a) Tracking expenditures. Starting in FFY 1999 CMS begins monitoring Medicare payments to RNHCIs.
(b) Carry forward. The difference between the trigger level and Medicare expenditures for a FFY results in a carry forward that either increases or decreases the unadjusted trigger level described in §403.750(d). In no case may the carry forward exceed $50,000,000 for an FFY.
