Maine Medicaid and MaineCare: Eligibility, Benefits, and Administration

MaineCare is Maine's implementation of the federal Medicaid program, jointly funded by the state and federal governments and administered by the Maine Department of Health and Human Services (DHHS). The program provides health coverage to low-income residents across a range of eligibility categories including children, adults, pregnant individuals, elderly residents, and people with disabilities. Federal matching funds, governed by the Federal Medical Assistance Percentage (FMAP), cover a substantial share of program costs, with Maine's FMAP rate adjusted annually by the Centers for Medicare & Medicaid Services (CMS).

Definition and scope

MaineCare operates under Title XIX of the Social Security Act, the federal statute establishing Medicaid nationally. Within Maine, the program is codified primarily in Title 22 of the Maine Revised Statutes and administered through the Division of Policy within DHHS's Office for Family Independence and Office of MaineCare Services.

Maine expanded Medicaid eligibility under the Affordable Care Act through a 2017 citizen-initiated referendum — one of the first states to do so by direct popular vote (Maine DHHS, MaineCare Expansion). Expansion extended coverage to adults ages 19–64 with household income at or below 138 percent of the federal poverty level (FPL). Implementation of the expansion took effect in January 2019.

Scope and coverage limitations: This page addresses MaineCare as administered under Maine state law and federal Medicaid statute. It does not cover Medicare (the federal program for adults 65 and older and certain individuals with disabilities), private insurance markets regulated by the Maine Bureau of Insurance, or Marketplace plans offered under the ACA exchange. Residents of federally recognized tribal nations in Maine may access coverage through both MaineCare and the Indian Health Service; tribal-specific eligibility considerations fall under the jurisdiction of Maine Tribal Governments and federal Indian health law.

How it works

MaineCare eligibility determinations are conducted by DHHS. Applications are processed through the portal at maine.gov or through paper submission. The eligibility process involves the following structured steps:

  1. Application submission — Individuals submit household composition, income, residency, and citizenship documentation to DHHS.
  2. Income verification — Modified Adjusted Gross Income (MAGI) methodology applies to most non-elderly, non-disabled applicants; institutional and long-term care populations use asset-based criteria.
  3. Category assignment — DHHS assigns applicants to the appropriate eligibility category (e.g., CHIP/Katie Beckett for children, adult expansion group, aged/blind/disabled).
  4. Benefit package determination — The assigned category determines the covered service package, cost-sharing requirements, and whether managed care or fee-for-service applies.
  5. Enrollment — Approved members receive a MaineCare ID and, where applicable, enrollment in a managed care organization (MCO).

Maine contracts with managed care organizations to deliver services to a portion of the MaineCare population. The state's MaineCare Benefits Manual, maintained by DHHS, defines covered services, reimbursement rates, and provider requirements for each benefit category. Providers must enroll with MaineCare and comply with billing standards established in the manual and in federal Medicaid regulations at 42 CFR Part 431 et seq.

Federal financing flows through a cost-sharing arrangement. Under standard FMAP, Maine's share of Medicaid costs is offset by federal reimbursement; the ACA expansion population receives a minimum 90 percent federal match, as established by 42 U.S.C. § 1396d(y).

Common scenarios

Children under 19: Children in households with income up to 200 percent FPL qualify for MaineCare; those in households between 200 and 300 percent FPL may qualify under the Children's Health Insurance Program (CHIP) component. Coverage includes preventive care, dental, vision, behavioral health, and long-term services.

Adult expansion enrollees: Adults ages 19–64 with income at or below 138 percent FPL qualify under the expansion group established by the 2017 referendum. This group receives a benchmark benefit package aligned with essential health benefits.

Aged, Blind, and Disabled (ABD) populations: Individuals receiving Supplemental Security Income (SSI) are typically automatically enrolled in MaineCare. Income and asset limits for this category differ from MAGI-based groups; asset thresholds apply. Long-term services and supports, including nursing facility care and home-based waiver services, are available to qualifying individuals within this category.

Dual eligibles: Individuals qualifying for both Medicare and MaineCare receive coordinated coverage. MaineCare functions as secondary payer and may cover Medicare cost-sharing and services Medicare does not cover, such as dental and non-emergency medical transportation.

Decision boundaries

Two primary distinctions govern MaineCare eligibility and benefit assignment:

MAGI vs. non-MAGI methodology: Most families, children, pregnant individuals, and adult expansion enrollees are evaluated using MAGI income rules — a standardized income calculation that excludes assets. Elderly and disabled applicants, and those seeking long-term care services, are evaluated under non-MAGI rules that include asset limits and may require spend-down calculations. The Maine DHHS MaineCare Benefits Manual specifies the applicable methodology by eligibility category.

Managed care vs. fee-for-service: Not all MaineCare enrollees receive services through the same delivery system. Certain populations — including those in the ABD category and individuals in long-term care — remain in fee-for-service. Others are enrolled in managed care arrangements. The structure of the delivery system affects which providers a member can access and how services are authorized.

Residency requirements limit MaineCare to Maine state residents. Individuals who establish residence in another state lose Maine eligibility. Undocumented individuals generally do not qualify for full MaineCare coverage, though emergency services are covered under federal law at 42 C.F.R. § 440.255.
