Medicare appeals

Since 1989, CMS has relied on Maximus to provide Medicare beneficiaries and providers with independent, conflict-free appeal decisions of health insurance denials. Because we have no financial affiliation with insurers or providers, we are the only conflict-free Independent Review Organization (IRO) providing Medicare appeals. We receive and review more than 600,000 appeals claims a year for Medicare, helping expedite the process to appeals determinations for citizens.

Expertise managing caseloads and backlogs

For decades we have worked collaboratively with CMS to implement process improvements and sustain a high level of customer satisfaction. With the adoption of our proven approaches, we have increased program efficiencies, reduced costs, and improved quality outcomes.

Connecting citizens with access to health information

Maximus supports the CMS Customer Accessibility Resource Staff in its effort to enhance beneficiary services and access to health information. This work is critical to achieving CMS’ mission to improve communications and implementations of agency enterprise solutions to meet the requirements of Section 504 of the Rehabilitation Act of 1973. As health communication experts, we specialize in making health information accessible and easy to understand.
