A plan can be listed because it was renumbered or replaced, not only because a company is leaving the county. When the same company keeps other plans there, members are usually moved to a replacement plan. Your plan should send you a notice, and Medicare’s Annual Enrollment Period (October 15 to December 7) is when you can compare and switch. “People enrolled” is the number enrolled in that plan today (CMS hides counts of 10 or fewer).

Why your county matters for coverage

In New Jersey, the health plans you can choose depend on where you live. Medicare Advantage and Part D plans are offered by service area, usually county by county, and marketplace premiums and carriers are set by area as well. Living in Mercer County means the options on this page apply to you, and plans in a neighboring county may differ.

  • Medicare: New Jersey State Health Insurance Assistance Program (SHIP) gives free, unbiased counseling at 1-800-792-8820. Ask which plans serve Mercer County specifically.
  • Marketplace plans: shop through Get Covered New Jersey; enter your Mercer County ZIP code to see what is offered.
  • Medicaid: apply through NJ FamilyCare (Division of Medical Assistance and Health Services).

New Jersey note: Get Covered New Jersey is run directly by the state's insurance regulator, the Department of Banking and Insurance, and layers a state-funded subsidy (New Jersey Health Plan Savings) on top of federal premium tax credits -- a combination unique to New Jersey's marketplace.
