Should states require plans to report both the core and supplemental rates for the Managed

It is recommended that MLTSS plans report both rates. However, if the state believes there are valid reasons for not reporting both rates, such as costly changes in assessment and care planning forms and information technology systems, it might consider phasing in the supplemental rates over time. For instance, in the first year of measure use (for example, measurement year 2018), the state could require MLTSS plans to report just the core rate, and then require that MLTSS plans report both core and supplemental rates for measurement year 2019 or 2020. Although they are called "supplemental rates," they are still very important, and should be viewed as "aspirational." MLTSS plans should strive to cover more assessment and care plan elements over time.
