Indiana has approximately 1.4 million Medicare beneficiaries , with the largest concentrations in Indianapolis, Northwest Indiana (Gary/Hammond), Fort Wayne, and Evansville. Medicare Advantage penetration has grown steadily across the state and is well above 40% in Indianapolis, somewhat lower in rural counties.1
What Medicare covers, and what it doesn't
Medicare is health insurance. It is not long-term-care insurance. This is the most expensive misconception in caregiving. Indiana families learn it most often when the 100-day Medicare rehab benefit ends after a hospital stay and the next bill is all-private-pay.
What Medicare does cover:
- Part A (Hospital). Inpatient stays, skilled nursing rehab for up to 100 days after a qualifying hospital admission (covered in full for first 20 days, then a daily coinsurance for days 21-100), hospice, and limited home health.
- Part B (Medical). Doctor visits, outpatient procedures, durable medical equipment, mental health, preventive care, ambulance.
- Part D (Drugs). Prescription drug coverage, either standalone or bundled into a Medicare Advantage plan.
What Medicare does not cover:
- Assisted living (any state, any setting)
- Memory care
- Custodial nursing-home care beyond the 100-day rehab window
- Long-term in-home aide hours
- Dental, vision, or hearing in Original Medicare
Original Medicare vs. Medicare Advantage in Indiana
Every Medicare-eligible person in the US chooses between two broad structures: Original Medicare (Parts A and B, usually paired with a Medigap supplement and a Part D drug plan) or Medicare Advantage (Part C, a private plan that bundles A, B, and usually D plus extras).
Indiana Medicare Advantage penetration is in the upper-30s to low-40s percent statewide and higher in Indianapolis where Advantage plans compete intensely.2 Rural Indiana counties tend to skew toward Original Medicare, partly because rural Advantage networks are thinner.
When Original Medicare + Medigap usually beats Advantage
- Your parent travels frequently or spends part of the year out-of-state. Original Medicare works nationally with any Medicare-accepting provider; Advantage plans have networks.
- Your parent has a serious or complex condition and wants unrestricted specialist access without referrals or prior authorizations.
- Your parent can afford the higher monthly premium for a Medigap supplement — in Indiana, $130–$260/month is typical for Plan G — in exchange for predictable out-of-pocket costs.
When Advantage usually beats Original Medicare
- Your parent lives in one Indiana county year-round and is generally healthy.
- The total of Original Medicare Part B premium + Medigap premium + Part D premium exceeds your parent's budget, and a $0-premium Advantage plan is available.
- Your parent values the extras — dental, vision, hearing, gym, sometimes meal delivery — that many Indiana Advantage plans bundle in.
Medigap in Indiana
If your parent chooses Original Medicare, they almost certainly also want a Medigap (Medicare Supplement) policy to cover deductibles and coinsurance. Medigap plans are federally standardized— Plan G in Indiana offers the same benefits as Plan G in any other state — but Indiana pricing and switching rules have specific details:
- Indiana is an age-rated state.Premiums rise as your parent ages. (Some states — Connecticut, New York, Massachusetts — require "community rating," where premiums don't rise with age. Indiana does not.)
- Guaranteed issue applies during the 6-month Initial Enrollment Period, when your parent turns 65 or first enrolls in Medicare Part B. Outside that window, insurers can use medical underwriting to deny coverage or charge more.
- Indiana does not have an annual switching window. Unlike California or Oregon, Indiana doesn't guarantee an annual Medigap switch with no underwriting. Once your parent picks a plan, switching can require requalifying medically.3
Medicare Savings Programs (MSPs) in Indiana
If your parent has limited income, they may qualify for one of the federal Medicare Savings Programs, administered in Indiana by FSSA:
- QMB (Qualified Medicare Beneficiary). Pays Part A and Part B premiums, deductibles, and coinsurance. Income limit ~$1,255/month individual (2026).
- SLMB (Specified Low-Income Beneficiary). Pays Part B premium only. Income limit ~$1,506/month individual.
- QI (Qualifying Individual). Pays Part B premium. Income limit ~$1,695/month individual.
Many Indiana seniors who qualify never apply because the application is opaque. SHIP counselors can walk your parent through it.
Annual Enrollment Period (AEP) in Indiana
Medicare AEP runs from October 15 through December 7 each year. During this window your parent can:
- Switch from Original Medicare to Medicare Advantage (or vice versa)
- Switch from one Advantage plan to another
- Add, drop, or switch a standalone Part D plan
Indianapolis sees substantial AEP marketing — TV, mailers, and in-person events. The single most important thing to know is that most ads are designed to drive enrollment in a specific plan, not to help your parent compare plans. The right comparison tool is Medicare.gov's Plan Finder, which lets you enter your parent's zip code, current prescriptions, and preferred providers, then ranks every plan by total annual cost.4
There is also a Medicare Advantage Open Enrollment Period (MA OEP) from January 1 through March 31 each year, during which someone already on Advantage can switch to a different Advantage plan or back to Original Medicare with Part D.
