Hammond, Munster and Highland sit on the Illinois line with Community Hospital in Munster and Franciscan Health Munster at their door, and half their specialists in Chicago.
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. Community Healthcare System’s flagship, Community Hospital in Munster, and Franciscan Health Munster contract with different carriers, Methodist Hospitals’ Northlake campus in Gary is minutes east, and a great many north-Lake County residents see doctors in Chicago — which an Indiana Advantage network may or may not include.
Hammond’s retirees are steel, rail and refinery families, and a union or company retiree plan is often the starting point. We set it beside the individual options, confirm your doctors on both sides of the state line, and lay Advantage beside a Medigap policy.

Your options
Which kind of plan fits you in Hammond?
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.
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.
Can I keep my Chicago specialist with an Indiana plan?
With Original Medicare and a Medigap policy, yes. With a Medicare Advantage plan, only if that Illinois provider is in the plan’s network, which 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.
