CMS has adopted a final rule that increases federal funding for certain Medicaid eligibility determination and enrollment activities under the ACA and updates regulations to reflect other Medicaid eligibility and business process changes. Under the rule, states may qualify for an enhanced 90% federal matching rate for design and development of new eligibility determination systems and a 75% federal matching rate for maintenance and operations of the new systems (compared to the current 50% match).  To qualify for enhanced funding, states must meet performance standards and conditions, including seamless coordination with Health Insurance Exchanges to be established under the ACA. The 90% rate will be available until December 31, 2015, and the 75% match will be available beyond that date if certain conditions are met. The rule is effective April 19, 2011.
