Medicare in the Northern Mariana Islands: 2025 Guide

The Commonwealth of the Northern Mariana Islands (CNMI) is a U.S. territory in the western Pacific whose approximately 12,000 Medicare beneficiaries face unique coverage challenges. As a territory, the CNMI receives capped federal Medicaid funding rather than the open-ended matching formula available to states, and access to specialists often requires medical evacuation to Guam or Hawaii. Saipan serves as the main island with the most healthcare infrastructure, while residents of Tinian and Rota have even more limited local access. This guide covers what CNMI Medicare beneficiaries need to know in 2025.

Medicare Advantage Plans in the Northern Mariana Islands

Medicare Advantage plan availability in the CNMI is extremely limited compared to the U.S. mainland and even relative to other territories. The small enrolled population, remote location, and limited local provider infrastructure make it commercially unattractive for most Medicare Advantage insurers to offer plans. Most CNMI Medicare beneficiaries are enrolled in Original Medicare (Parts A and B), which covers medically necessary services provided by any Medicare-enrolled provider. Saipan has the most healthcare resources in the territory, including the Commonwealth Health Center (CHC), which serves as the main hospital and the primary point of contact for Medicare-covered hospital and medical services.

A critical reality for CNMI beneficiaries is that many specialized medical services are not available locally. When a beneficiary requires specialist care — cardiology, oncology, complex surgery, or other advanced treatments — medical evacuation to Guam or Hawaii is often necessary. Original Medicare covers medically necessary services at Medicare-enrolled facilities in Guam and Hawaii, but transportation and logistical costs associated with medical evacuation are not typically covered by Medicare. Beneficiaries should understand this gap and plan accordingly. Some beneficiaries explore supplemental coverage options or rely on CNMI Medicaid to help bridge these costs. The CNMI SHIP counselors at (670) 664-2558 can provide guidance on coverage options and how to navigate medical travel situations.

Part D prescription drug coverage is available to CNMI Medicare beneficiaries through standalone Part D plans, though the selection of plans may be more limited than on the mainland. Beneficiaries who struggle to afford their medications should inquire about Extra Help (the Low Income Subsidy program) through the Social Security Administration. CNMI SHIP can help determine eligibility and assist with the application.

Medicare Savings Programs in the Northern Mariana Islands

The CNMI administers a Medicaid program, but as a U.S. territory it operates under a fundamentally different financing structure than states. U.S. territories receive capped federal Medicaid funding — a fixed federal contribution ceiling — rather than the open-ended federal matching formula that states receive. This cap constrains what CNMI Medicaid can cover and the number of people it can serve. Despite these limitations, Medicare Savings Programs (MSPs) are available for qualifying low-income Medicare beneficiaries in the CNMI. The QMB, SLMB, and QI programs help pay Medicare premiums and, in the case of QMB, Part A and Part B cost-sharing as well. Qualifying for an MSP automatically qualifies you for federal Extra Help with Part D drug costs.

MSP applications in the CNMI are processed through the CNMI Medicaid program. Contact the CNMI Department of Public Health or the Division of Medicaid for application assistance and current eligibility requirements. Because the CNMI's Medicaid program operates under funding constraints, availability of benefits can be more limited than in states. CNMI SHIP counselors at (670) 664-2558 can help you understand what assistance is currently available and help you apply for all programs you may qualify for.

State Pharmaceutical Assistance in the Northern Mariana Islands

The CNMI does not have a State (or Territory) Pharmaceutical Assistance Program (SPAP). Beneficiaries who need help with prescription drug costs should apply for the federal Extra Help program through Social Security at 1-800-772-1213 or SSA.gov. Extra Help can reduce or eliminate Part D premiums, deductibles, and copayments for eligible enrollees. Given the CNMI's geographic isolation, access to pharmacies and prescription medications can sometimes be challenging — CNMI SHIP counselors can provide guidance on resources available locally and remotely for reducing medication costs.

Getting Free Medicare Help in the Northern Mariana Islands

CNMI SHIP is administered through the CNMI Division of Aging, located in Saipan, and provides free, confidential Medicare counseling to beneficiaries across the territory. CNMI SHIP counselors understand the unique challenges faced by CNMI Medicare enrollees, including limited local healthcare access, medical evacuation needs, and the territory's distinct Medicaid financing structure. Counselors can help you understand your Original Medicare benefits, identify any available Medicare Advantage or Part D options, apply for MSPs and Extra Help, and navigate questions about coverage when receiving care outside the CNMI in Guam, Hawaii, or the mainland United States.

Contact CNMI SHIP by calling the Division of Aging at (670) 664-2558. The Division of Aging office is located in Saipan and serves beneficiaries on all inhabited islands of the CNMI — Saipan, Tinian, and Rota. Residents of Tinian and Rota who cannot travel to Saipan for in-person counseling are encouraged to call for phone counseling. Given the small size of the counseling program relative to the vast geographic and logistical challenges in the CNMI, contacting SHIP early — especially before the Annual Enrollment Period — is strongly recommended to ensure you get the help you need.
