The new provider-enrollment and claims-processing solution is called MESA: Medicaid Enterprise System Assistance, and the agency’s goal is for this modernization to enhance connections between health services systems and improve access to health information for our Medicaid providers and the members they serve.
The new system – MESA – is expected to go-live later in 2022, replacing outdated technology with a more efficient version that is easier to maintain. Recognizing how critically important it will be to ensure a smooth transition, DOM is focused on providing clear information and resources over the coming months to help all providers prepare for the switchover.
Although it will be an adjustment, MESA will allow for some distinct advantages over the current system. For example, a new and improved provider portal will allow for a streamlined provider-enrollment process. Healthcare providers will be able to submit and adjust claims in real-time for each claim type and submit batches of transactions, as well as verify a patient’s eligibility status quickly and easily. The new system will also allow for a centralized credentialing process, eliminating the need for providers to credential with DOM and each coordinated care organization.
