When is the federal financial participation (FFP) limit demonstration due? And for what period of time? Why is the Centers for Medicare & Medicaid Services using calendar year for this demonstration?

Federal financial participation (FFP) limit demonstrations for durable medical equipment (DME) will be due 3 months after the end of the calendar year for the previous calendar year (i.e., January 1-December 31). The first DME FFP limit demonstration will be due by March 31, 2019 and will contain data for the period of January 1, 2018 to December 31, 2018. This reporting period was selected to coincide with the effective date of the statute (January 1, 2018).
