When CMS indicated that the one-year waiting period would indeed apply to participants who wished to participate with different downstream episode initiators15, many Convener participants immediately objected. CMS, for its part, indicated, before the expiry of a deadline of 1 March 2019, that the waiting time would not prevent participants agreeing to apply for Model Year 3, which would make it possible to terminate participants agree – several of whom have concluded advanced BPCI agreements with CMS – (whether retroactive to 1 March, or prospective for other denunciations), some or any such agreement without fear of being excluded from the notification period of Model Year 3. With this change, the one-year waiting period is now formally abolished. In addition to the changes that are reflected in the application for Model Year 3, CMS has offered current participants the opportunity to modify their existing BPCI Advanced model contracts. New applicants have until June 24, 2019 to apply. In addition, current bpci advanced participants have until June 1, 2019 to make an optional amendment to the original BPCI Advanced Agreement, recently published by CMS, as described below. . . .
