2026-2027 Medigap Premium Trends: Why Rates Are Rising and How to Lock In Lower Costs
2026-2027 Medigap Premium Trends: Why Rates Are Rising and How to Lock In Lower Costs
Medicare Supplement (Medigap) premiums have been climbing steadily, and 2026-2027 is shaping up to continue that trend. If you’re already enrolled or approaching Medicare eligibility, understanding why rates rise — and what you can do about it — could save you hundreds of dollars per year.
Quick Answer
Medigap premiums are projected to increase 5-12% in 2026-2027, driven by rising healthcare costs, an aging beneficiary pool, and carrier rate adjustments. The single most effective strategy is enrolling during your Medigap Open Enrollment Period (the 6 months after you turn 65 and enroll in Part B) to secure guaranteed-issue pricing without medical underwriting. After that window closes, your options narrow significantly — but switching to a different pricing method or carrier can still reduce costs.
Key Takeaways
- Plan G premiums averaged $155-$210/month nationally in early 2026, with some states exceeding $250/month for new enrollees
- Attained-age rated plans tend to have the lowest starting premiums but increase the fastest over time
- Issue-age and community-rated plans offer more predictable long-term costs, even if initial premiums are higher
- Household discounts can reduce premiums by 7-14% with many carriers
- Switching during guaranteed-issue windows (like your birthday rule in certain states) avoids medical underwriting
- High-deductible Plan G premiums run $50-$80/month lower than standard Plan G, potentially saving $600-$960/year
Why Medigap Premiums Keep Rising
Healthcare Cost Inflation
Medical costs continue to outpace general inflation. Hospital costs, physician fees, and diagnostic testing prices have all contributed to higher claims payouts for Medigap carriers. When claims costs rise, carriers pass those increases to policyholders through annual rate adjustments.
In 2025, the average Medigap claim per policyholder increased approximately 6.3% year-over-year. Carriers projecting similar or higher claims trends for 2026-2027 are adjusting premiums accordingly.
The Aging Beneficiary Pool
Approximately 11,200 Americans turn 65 every day. This wave of new beneficiaries — the tail end of the Baby Boomer generation — is expanding the Medicare-eligible population. While more enrollees mean more premium revenue, older beneficiaries also file more claims, creating upward pressure on rates across all plans.
By 2027, an estimated 67 million Americans will be enrolled in Medicare, up from 65.7 million in 2025. This demographic shift means carriers are pricing for a population that will, on average, use more healthcare services each year.
Carrier Market Consolidation
The Medigap market has seen consolidation among top carriers. Fewer competitors can reduce pricing pressure. While state insurance regulators must approve rate increases, the reduced competitive landscape means fewer low-cost alternatives for consumers.
Medical Loss Ratio Requirements
Federal law requires Medigap carriers to spend at least 65% of premium revenue on claims (the Medical Loss Ratio, or MLR). When claims costs spike, carriers must raise premiums to maintain compliance. This regulatory floor protects consumers from predatory pricing but also means rates track closely with actual healthcare costs.
How Pricing Methods Affect Your Premium Trajectory
Understanding how your carrier calculates your premium is critical for projecting long-term costs. Our guide to Medigap pricing methods covers this in depth, but here’s the essential comparison:
Attained-Age Rated Plans
Your premium increases as you get older, typically with annual age-based adjustments plus general rate increases.
- Starting premium: Usually the lowest of the three methods
- Annual increase: 3-7% per year from age adjustments alone, plus 2-5% from general rate increases
- 10-year impact: A $120/month premium at 65 could reach $200-$240/month by 75
- Best for: People who want the lowest cost right now and plan to switch plans later
Issue-Age Rated Plans
Your premium is based on your age when you first buy the policy. It doesn’t increase because you get older — only from general rate increases.
- Starting premium: Higher than attained-age plans for the same coverage
- Annual increase: 2-5% from general rate adjustments only
- 10-year impact: A $150/month premium at 65 might reach $180-$210/month by 75
- Best for: People who want predictable, slower-increasing premiums long-term
Community-Rated Plans
Everyone in the same geographic area pays the same premium regardless of age. Increases come only from general rate adjustments.
- Starting premium: Can be higher for younger enrollees but lower for older ones
- Annual increase: 2-4% from general rate adjustments
- 10-year impact: Most predictable trajectory
- Best for: People enrolling at older ages who want to avoid age-based jumps
The bottom line: If you’re comparing plans purely on the first-year premium, you may be costing yourself money over time. Use our Medigap price-by-age chart to project total costs over 5, 10, and 15 years.
Projected 2026-2027 Rate Increases by Plan
Based on filed rate requests and historical patterns, here’s what to expect:
Plan G (Most Popular for New Enrollees)
- 2026 average premium: $155-$210/month (varies by state and carrier)
- Projected 2027 increase: 5-9%
- Estimated 2027 average: $165-$230/month
- Plan G remains the best value for comprehensive coverage, but the gap between standard and high-deductible versions is widening
Plan N
- 2026 average premium: $105-$155/month
- Projected 2027 increase: 4-8%
- Estimated 2027 average: $112-$168/month
- Copays ($20 for office visits, $50 for ER) help keep premiums lower, but total out-of-pocket depends on usage
Plan F (Closed to New Enrollees Since 2020)
- 2026 average premium: $195-$275/month (for grandfathered enrollees)
- Projected 2027 increase: 7-12%
- Estimated 2027 average: $215-$310/month
- This plan is experiencing the steepest increases because its risk pool is aging rapidly with no new younger enrollees
High-Deductible Plan G
- 2026 average premium: $55-$90/month
- Projected 2027 increase: 4-7%
- Estimated 2027 average: $60-$97/month
- The $2,700 deductible (2026 figure, adjusts annually) means you pay out-of-pocket until the deductible is met, then full Plan G benefits kick in

7 Strategies to Reduce Your Medigap Premiums
1. Enroll During Your Open Enrollment Period
The 6-month window after you turn 65 and enroll in Medicare Part B is your golden opportunity. During this period, you can buy any Medigap plan available in your state with no medical underwriting. Once this window closes, carriers can deny you or charge higher premiums based on your health history.
2. Consider Plan N Instead of Plan G
Plan N offers similar coverage to Plan G with small copays ($20 office visits, $50 emergency room visits) and does not cover Part B excess charges. For healthy individuals who rarely see the doctor, the premium savings of $30-$60/month can far exceed the occasional copay. Compare the two in detail in our Plan G vs. Plan N comparison.
3. Ask About Household Discounts
Many carriers offer 7-14% discounts if both spouses enroll, or if you attest that another adult lives in your household. This discount applies to both new and existing policies — call your carrier to confirm eligibility.
4. Shop Across Multiple Carriers
Medigap plans are standardized by letter (Plan G from Carrier A is identical to Plan G from Carrier B). The only difference is price. Getting quotes from 5-8 carriers in your area can reveal significant price differences for identical coverage — sometimes $50-$80/month for the same plan.
5. Switch to a High-Deductible Plan
If you’re healthy and have savings to cover the deductible, high-deductible Plan G can save $600-$1,200/year in premiums. The deductible is $2,700 in 2026 (adjusted annually for inflation), but if you don’t meet it, the premium savings are pure gain.
6. Use State-Specific Guaranteed-Issue Windows
Several states offer special enrollment windows where you can switch Medigap plans without medical underwriting:
- California, Oregon, and Missouri: Birthday rule — you can switch plans within 30 days of your birthday each year
- Connecticut, Maine, Massachusetts, and New York: Continuous guaranteed issue — you can switch plans at any time
- Maryland and Washington: Specific annual enrollment periods
Check our Medicare Supplement birthday rule guide by state for full details.
7. Evaluate Whether Medigap Is Still the Right Fit
If premiums have become unaffordable, Medicare Advantage plans offer an alternative with $0 or low premiums (though with network restrictions and different cost-sharing structures). This isn’t the right choice for everyone, but it’s worth comparing. Our Medigap vs. Medicare Advantage cost comparison can help you evaluate the tradeoffs.
What to Watch for in Late 2026 and 2027
Part B Premium Changes
The Medicare Part B premium directly affects Medigap costs because Medigap plans cover the Part B coinsurance. CMS is expected to announce the 2027 Part B premium in November 2026. If the premium rises (currently projected at $185-$195/month for 2027, up from $185 in 2026), it could trigger additional Medigap rate adjustments.
IRMAA Surcharge Thresholds
Income-Related Monthly Adjustment Amount (IRMAA) thresholds are adjusted periodically. If your modified adjusted gross income exceeds $103,000 (individual) or $206,000 (married filing jointly), you’ll pay higher Part B and Part D premiums. These surcharges don’t directly affect Medigap premiums, but they increase your total healthcare costs and should factor into your budget planning.
New Carrier Entrants
Several regional insurance companies have announced plans to enter or expand their Medigap offerings in 2026-2027. New entrants often compete on price to build market share, which could create opportunities for lower premiums in certain states.
Tracking Your Rate Increases
Don’t just accept annual premium increases without questioning them. Here’s what to do:
- Compare your new rate against current market rates using our annual rate increase estimator
- Request a rate justification from your carrier — they’re required to explain increases
- Shop your plan against competing carriers every 12-18 months
- Check state-specific switching opportunities that don’t require medical underwriting

Frequently Asked Questions
Why did my Medigap premium increase even though I haven’t filed any claims?
Medigap premiums are pooled — your rate is based on the claims experience of your entire policy group, not just your individual claims. When healthcare costs rise across the pool, everyone’s premium increases. Additionally, if your plan uses attained-age pricing, your premium automatically rises each year as you get older.
How much will Medigap Plan G cost in 2027?
Based on filed rate requests and historical trends, Plan G is projected to average $165-$230/month nationally in 2027, up from $155-$210 in 2026. Your actual premium depends on your state, age at enrollment, carrier, and pricing method. Attained-age plans will see the steepest increases, while community-rated plans will have more moderate adjustments.
Can I switch Medigap plans to get a lower premium?
Yes, but it depends on your state and health status. In most states, switching requires medical underwriting after your initial open enrollment period closes. However, some states offer guaranteed-issue switching windows (birthday rules, continuous guaranteed issue). Even with underwriting, if you’re in good health, switching to a different carrier for the same plan letter can yield significant savings since plans are standardized.
Is High-Deductible Plan G worth the savings in 2026-2027?
High-Deductible Plan G saves most enrollees $600-$1,200/year in premiums compared to standard Plan G. With the 2026 deductible at $2,700, you come out ahead if your annual medical expenses stay below the premium savings plus the deductible difference. For healthy individuals who rarely meet the deductible, HD Plan G is often the most cost-effective Medigap option available.
Will Plan F premiums keep rising faster than other Medigap plans?
Yes. Plan F is closed to new Medicare enrollees (since January 1, 2020), which means its risk pool is aging with no influx of younger, healthier members. This aging dynamic consistently drives steeper rate increases — typically 7-12% annually compared to 4-9% for Plan G. If you’re still on Plan F, now is the time to evaluate whether Plan G (which has nearly identical coverage) could save you money.
How do I know if my Medigap premium is too high?
A good benchmark: your premium should be within 15% of the average for your plan letter, age, and state. If it’s significantly higher, you’re likely overpaying. Get quotes from at least 5 carriers for the same plan letter in your area. If your current premium exceeds the lowest quote by more than 20%, switching could save you $300-$900/year for identical coverage.
