All applications, including initial enrollments and maintenance cases, have enrollment screening requirements. These screening requirements are based on categorical risk level.
Categorical Risk Levels
The ACA mandates that State Medicaid agencies establish categorical risk levels of limited, moderate, or high for initial applications or new practice locations. For provider types that are not recognized by Medicare, states must assess the appropriate categorical risk level by provider type A full listing of the criteria can be found in the Risk Category Assignments (PDF). For additional information , please see CMS's Frequently Asked Questions.

Fees and Surety Bonds
Providers who are newly enrolling, revalidating, or adding new practice locations with MaineCare must pay an application fee. This fee varies from year to year.
Home Health Agencies (HHA) and Durable Medical Equipment (DME) providers are required to provide surety bonds when enrolling as a new provider, revalidating, or adding a new service location.
Non-billing, Ordering, Prescribing, and Referring (NOPR) Providers
Billing providers must provide the NPI of an enrolled MaineCare practitioner who is ordering, prescribing, or referring on their claims to avoid claim denials. These practitioners are known as NOPRs and must enroll in MaineCare independently or as part of an organization. For more detail about NOPR requirements, please see Non-billing, Ordering, Prescribing, and Referring Provider Requirements (PDF).
Effective April 1, 2021, all prescribing providers must either be enrolled as a MaineCare provider or, where applicable, be added as a NOPR provider under their organization’s MaineCare provider enrollment to prevent disruption of pharmacy services for MaineCare members. See the NOPR Not Enrolled Letter (PDF) for more detail about this requirement.
Revalidating your Enrollment Application
Providers must revalidate their information with MaineCare every 5 years, or 3 years for Durable Medical Equipment (DME) providers. For more detail about Revalidation see the Revalidate as a Current Provider (PDF).
