North Dakota did not expand Medicaid but has relatively low uninsured rates due to high employment from oil, agriculture, and military. The ACA marketplace covers 35,000+ North Dakotans. Medicare covers 130,000+ residents. The Bakken oil boom and Prairie State military bases create unique employment-based coverage patterns.

Williams County residents can access Medicare Advantage plans from carriers including UnitedHealthcare, Humana, Aetna, Cigna, and Wellcare, among others. The number of available plans varies by ZIP code — some counties have dozens of options while rural areas may have fewer. A licensed Medicare agent will pull every plan available at your specific address at no cost.
Williston residents turning 65 should enroll during their 7-month Initial Enrollment Period, which starts 3 months before their 65th birthday month. Missing this window means waiting until the General Enrollment Period (January 1–March 31) and potentially facing a permanent late enrollment penalty on your Part B premium. If you have employer coverage, different rules apply — contact a licensed agent to confirm your exact timeline.
Medicare Advantage (Part C) replaces Original Medicare with an all-in-one plan from a private carrier, typically offering lower premiums but requiring in-network providers in Williams County. A Medicare Supplement (Medigap) policy works alongside Original Medicare to cover out-of-pocket costs like deductibles and coinsurance, giving you access to any provider nationwide that accepts Medicare. The right choice depends on your health needs, budget, and preferred providers.
