Indiana carriers file Medigap in 85 rating areas for 92 counties — close to one price zone per county, the finest slice of any state we publish. In Marion County, 27 carriers quote Plan G at 65 from $118.22 to $333.67 (CSG Actuarial, pulled September 11, 2026); the statewide floor drops to $109.46 in Allen County, still Bankers Fidelity (Atlantic Capital Life). Federal law makes the coverage behind every one of those numbers identical.
GPM Health and Life's $333.67 runs 2.8 times Bankers Fidelity (Atlantic Capital Life)'s $118.22 for the same plan letter, a $215.45-a-month gap worth $51,708 over 20 years if neither line ever files an increase again, which neither will. Below: the full monthly bill with Part B added, county by county, and every carrier that filed a 2026 increase.

What Plan G and Plan N Cost in Marion County at 65
ZIP 46239 in Marion County, female, non-tobacco, individual, no discount applied, pulled September 11, 2026. This is one table out of 85 Indiana rating areas — your own ZIP can land on a different line entirely.
| Plan | Cheapest filing | Carrier | Highest filing | Carrier | Monthly spread | Carriers |
|---|---|---|---|---|---|---|
| Plan G | $118.22 | Bankers Fidelity (Atlantic Capital Life) | $333.67 | GPM Health and Life | $215.45 | 27 |
| Plan N | $85.00 | Members Health | $196.93 | WPS Health Solutions | $111.93 | 26 |
Plan N's floor is $85.00, $33.22 under the cheapest Plan G, and it belongs to Members Health, not Bankers Fidelity (Atlantic Capital Life), the Plan G leader. Plan N trades that gap for copays: up to $20 at some office visits and up to $50 at an emergency room visit that does not end in admission, and it hands you Part B excess charges too. One rule holds on both letters: the $283 Part B deductible stays unpaid.
Go deeper: the full Indiana monthly bill with the Part B premium added, county by county.
Three Things That Decide an Indiana Medigap Price
Rate Type: 25 of 27 Price on Attained Age
September 11, 2026's mix: 25 attained age, 1 issue age, 1 community rated. Attained-age pricing climbs on birthdays, then climbs again whenever the carrier refiles. Bankers Fidelity (Atlantic Capital Life)'s Marion County Plan G goes $118.22 at 65, $124.20 at 70, $147.57 at 75 and $174.98 at 80. Everence Association is the one issue-age filing here, set by the age you buy at. AARP / UnitedHealthcare is the one community-rated filing, one price at every age.
Rating Area: 85 Price Zones Across 92 Counties
Indiana carriers file by rating area, close to one per county, the finest slice of any state in our file.

Indiana Medigap Rate Filings in the 2026 Reports
18 Indiana rows carry a Plan G percentage in the December 2025-to-September 2026 CSG records; 18 went up, 5 by 30% or more. HealthSpring Insurance (HCSC) tops the list at +42.7%, effective April 1, 2026. Remember a filing moves one carrier's whole block, not a single renewal notice, and the effective date often lands weeks or months away from the report month that first disclosed it.

The Lettered Plans, and What Each One Leaves With You
One federal benefit chart governs every carrier's lettered plans, in Indiana or anywhere else. On Plan G, only the $283 Part B deductible is yours to pay; Plan N shares that plus copays and Part B excess charges; Plan F, closed to anyone newly eligible since January 1, 2020, covers everything. Even closed to new buyers, Plan F held 119,959 Indiana lives as of December 2023, against 202,217 on Plan G and 32,798 on Plan N — legacy policyholders who bought before the cutoff and never moved (NAIC via AHIP, statewide by letter).
| Plan | What it leaves with you | In one line |
|---|---|---|
| Plan A | Both deductibles, skilled nursing coinsurance, excess charges, foreign travel | The basic benefits every letter includes |
| Plan B | Part B deductible, skilled nursing coinsurance, excess charges, foreign travel | Plan A plus the Part A deductible |
| Plan D | Part B deductible and Part B excess charges | Plan G without excess-charge coverage |
| Plan G202,217 Indiana lives | The Part B deductible only | The letter with the most Indiana lives (NAIC, December 2023) |
| High-Deductible G | A yearly deductible before the plan pays | Lower premium, more first-dollar risk |
| Plan K | Half of most cost-sharing, up to a yearly cap | Lowest premium tier by design; half of most cost-sharing stays with you |
| Plan L | A quarter of most cost-sharing, up to a yearly cap | Between K and N |
| Plan N | Part B deductible, office and ER copays, excess charges | The lower-premium trade most callers weigh against G |

Write These Down Before You Dial
- • Part B premium: $202.90/month, standard 2026 rate, billed by Medicare separately from any Medigap premium.
- • Part B deductible: $283/year — neither Plan G nor Plan N touches this one.
- • Part A deductible: $1,736 per benefit period, fully covered by Plan G and Plan N.
- • Indiana Plan G, age 65: $109.46 in Allen County up to $333.67 in Marion County; statewide median $166.35.
- • Statewide enrollment: 370,851 Medigap policies as of December 2023; 202,217 of them Plan G (NAIC via AHIP).
- • Your window: six months, starting the month you're 65 and on Part B — no health questions asked, at any of the 27 carriers, no exceptions after it closes.
Where Every Indiana Figure Above Comes From
- CSG Actuarial supplies both the base rates (pulled September 11, 2026) and the filing-change history (December 2025 through September 2026); nothing here is typed by hand.
- Quoted profile is fixed across the page: a non-tobacco individual woman, no household discount. Change any one of those and the numbers move.
- All 92 Indiana counties were priced at the ZIP with the most land inside them. Marion County (ZIP 46239) anchors this page; Allen County stands in for the typical 3-county grouping used where several counties share one filed rate.
- A spread is simply the priciest carrier's cheapest class minus the cheapest carrier's, same county, same age. Multiply by 240 for the no-increase, 20-year projection.
- 27 carriers returned a Marion County Plan G quote on September 11, 2026. That number shifts as carriers enter, exit or refile a block.
- Cross-state superlatives (lowest, second-lowest, ranked) are recalculated at every build from every state file we license, never asserted from memory.
- Neither Plan G nor Plan N pays the $283 Part B deductible; that rule doesn't change by state or carrier.
