About the Independent Review Organization (IRO) for the Maryland Department of Health (MDH)

About Us image

On behalf of the Maryland Department of Health (MDH), Office of Health Services, MAXIMUS Federal Services serves as the Independent Review Organization (IRO), providing medical necessity case review of services delivered by a health care provider to a Maryland Medicaid beneficiary enrolled with and reimbursed by a Maryland Medicaid Managed Care Organization (MCO).

Before the IRO conducts a medical necessity case review, the provider must go through the full appeals process provided by the MCO.

In accordance with the Code of Maryland Regulations (COMAR), Maryland Medical Managed Care Organizations (MCOs) are required to have a provider appeal process to resolve provider complaints, including claim denials, because the services were considered not medically necessary by the MCO.

The MCO appeals process was previously the provider's only recourse in overturning an MCO claims denial other than to litigate the case through the courts. As a result of Provider's requests, the Maryland Department of Health (MDH) has established this new process with an IRO, as means for Providers to receive an independent review of these medical necessity denials.
