No, there is no deadline by which a state must let the federal government know its intention regarding the Medicaid expansion. Nor is there any particular reason for a state to link its decision on the Exchange with its decision on the Medicaid expansion. States have a number of decision points in designing their Medicaid programs within the broad federal framework set forth in the federal statute and regulations, and the decision regarding the coverage expansion for low-income adults is one of those decisions.
As with all changes to the Medicaid state plan, a state would indicate its intention to adopt the new coverage group by submitting a Medicaid state plan amendment. If a state later chooses to discontinue coverage for the adult group, it would submit another state plan amendment to CMS. The state plan amendment process is itself undergoing modernization. As part of an overall effort to streamline business processes between CMS and states, in early 2013 CMS will begin implementing an online state plan amendment system to assist states in filing state plan amendments. We will be discussing the submission process for Affordable Care Act-related state plan amendments on our monthly State Operations and Technical Assistance calls with states and will be available to answer questions through that process.
While states have flexibility to start or stop the expansion, the applicable federal match rates for medical assistance provided to "newly eligible individuals" are tied by law to specific calendar years outlined in the statute: states will receive 100 percent support for the newly eligible adults in 2014, 2015, and 2016; 95 percent in 2017, 94 percent in 2018, 93 percent in 2019; and 90 percent by 2020, remaining at that level thereafter.
