(v) Alternative applicable percent Notwithstanding any other provision of law, the Secretary may define the applicable percent for purposes of a given alternative payment model (or for purposes of partial qualifying APM participants under section 1848(q)(1)(C)(iii)(III)) to mean a percentage amount that is lower than the amount (or range) otherwise specified in such preceding clause (or, as applicable, under section 1848(q)(1)(C)(iii)(III)), if there is good cause to support such alternative applicable percent, including where an alternative payment model’s design warrants use of such alternative applicable percent. In no case shall the Secretary designate an alternative applicable percent that exceeds the maximum applicable percent specified in the preceding clause (or, as applicable, under section 1848(q)(1)(C)(iii)(III)) for the applicable year
