Best Medicare Part B Supplement Policy for 2026
Key Takeaways
- Plan G dominates: Plan G has become the standout choice for 2026, offering near-complete coverage except for the Medicare Part B deductible (expected to be about $240 in 2026). The benefits are standardized, so the main differentiators are price, service, and extra perks from the insurer.
- Top carriers to consider: Based on national research, Mutual of Omaha delivers the best overall value; UnitedHealthcare/AARP offers extensive plan options and member tools; Cigna and HealthSpring are recognized for aggressive discounts and lower pricing; State Farm boasts very low complaint levels among enrollees; BCBS and Aflac are praised for competitive rates, and Aetna provides comprehensive solutions including dental and vision up-sells.
- Cost savings versus Plan F: Plan G premiums commonly range $100-$236 per month, compared to Plan F’s $150-$250. Plan G covers almost everything but the Part B deductible, frequently costing less than F even after accounting for that deductible-ideal for those seeking predictable expenses.
- Enrollment tips: Always compare premiums by ZIP code, as costs may differ dramatically; utilize your “Initial Enrollment Period” (six months post-Medicare Part B enrollment) for guaranteed acceptance. Ask about possible household or automatic payment discounts.
What Medigap Covers (Part A/B Gaps Explained)
Medigap, also referred to as Medicare Supplement insurance, is designed to fill the cost gaps left by Original Medicare. Plan G, in particular, addresses almost all major out-of-pocket costs for both Medicare Part A (hospital) and Part B (outpatient/doctor) services. Here’s how the leading Medigap policies help you manage your health costs in 2026:
- Part A: Plan G covers all hospital deductibles and coinsurance charges, including hospital stays beyond the basic 60-day benefit (up to 365 additional lifetime days), full coverage for skilled nursing facility coinsurance, the initial three pints of blood per year, and hospice coinsurance or copays.
- Part B: Covers all coinsurance and copayments (after the deductible), all Medicare Part B excess charges (billed above Medicare-approved rates), and urgent foreign travel emergency care up to set plan limits. The only routine gap you’ll pay with Plan G is the modest Part B deductible (projected at $240 in 2026).

Enrollment Rules & Tips
Understanding Medigap’s enrollment periods and coverage rules is crucial for getting the best deal and avoiding penalties or denials. Here’s what you need to know for 2026:
- Open Enrollment: Your Medigap Open Enrollment window is six months, starting with your Medicare Part B effective date. During this period, you have a guaranteed right to buy any policy sold in your state-no health questions or underwriting.
- Switching policies: Medicare rules allow plan changes annually (typically during the Annual Election Period, October to December), or if you lose coverage/move. However, you may face underwriting or denial outside your original enrollment window. Consult with expert brokers who track rate changes every year for your ZIP code.
- Cost-saving tips: Always gather at least three quotes from licensed agents or brokers. Look for carriers with NAIC consumer complaint ratios under 1.0 and excellent financial ratings from agencies such as A.M. Best. Healthy seniors can further lower premiums by considering high-deductible Plan G options.
- Special enrollment tips: Residents in certain states, such as California and Oregon, benefit from a “birthday rule” that allows them to switch Medigap plans annually without underwriting.

Plan G vs. Others: Cost Calculator Example
To illustrate your real-world expenses, compare typical annual out-of-pocket costs for a 70-year-old, non-smoking enrollee in an average-cost ZIP code, assuming moderate healthcare usage in 2026:
- Plan G (Mutual of Omaha, $180/month): Annual premium is $2,160. Additional annual Part B deductible outlay: $240. Total out-of-pocket: $240.
- Plan N ($160/month): Annual premium is $1,920. Add $240 for Part B deductible, an estimated $40 for two office visit copays, $50 for one ER visit, and $500 for excess charges (not covered). Total expected out-of-pocket: $830.
- Plan F ($220/month if eligible): Annual premium is $2,640. All out-of-pocket costs are paid by the plan. Total: $0-though this plan is not available to new Medicare enrollees since 2019.
Key takeaway: Plan G commonly saves $480/year compared to Plan F, and can make you $590 better off than Plan N per year if you expect even moderate use and encounter any excess charges. However, healthy and low-usage individuals might prefer Plan N for the lower initial premium. Your exact savings will depend on how much care you use and your area’s ZIP-specific premium, which you can estimate through our regional comparison tools or a North Carolina-specific guide.
Always verify that your doctor accepts Medicare assignments if you’re considering Plan N, as it does not cover Part B excess charges, a key distinction from Plan G.
