Gary and Merrillville are Methodist Hospitals country — Northlake and Southlake — with Franciscan Health Crown Point to the south, the Dunes to the east, and a steel-retiree population with union plans to sort out.
What to know before you compare plans in Lake County
Lake County offers a wide Advantage menu, every Medigap carrier in Indiana and the full Part D lineup. Methodist Hospitals’ two campuses, Northlake in Gary and Southlake in Merrillville, and Franciscan Health’s new Crown Point hospital contract with different carriers, and Chicago is forty minutes west for anything the Region does not do.
Gary’s retirees are largely steelworkers and their families, and a union retiree plan is frequently the best coverage on the table and a one-way door if you leave it; we compare before anyone cancels anything. Porter County’s dune towns just east add a snowbird population whose plans need to travel.

Your options
Which kind of plan fits you in Gary?
Medicare Advantage
All-in-one Part C plans, often $0 premium, that use a network — so whether your doctors are IU Health, Ascension St. Vincent, Community, Franciscan, Parkview or Deaconess matters.
Medigap pairs with Original Medicare and lets you see any provider nationwide that accepts Medicare — in Indianapolis, in Louisville or Chicago, or in Florida for the winter. Indiana now has a birthday rule for switching.
Advantage plans built for a chronic condition, for nursing-facility care, or for people with both Medicare and Indiana Medicaid through PathWays for Aging.
Which Medicare plans are available in Gary and Merrillville?
Lake County typically offers a wide Medicare Advantage menu, every Medigap carrier in Indiana, and the full Part D lineup, set by ZIP code and changing each plan year.
Is Methodist Hospitals in my plan’s network?
Methodist, Franciscan and Community Healthcare System contract with different Advantage plans, changing year to year. With Original Medicare and a Medigap policy there is no network. We confirm before you enroll.
How much does your help cost?
Nothing. Independent agents are paid by the carriers when you enroll, so comparing plans and reviewing your coverage each year is free to you.
