Frequently Asked Questions

Which Medicare Supplement plan is best in 2025 - Plan G or Plan N?

Plan G vs Plan N comparison (2025 analysis): Plan G (Most Popular): Covers everything except Medicare Part B deductible ($257 in 2025).

Premium: $120-$180/month average ($1,440-$2,160/year).

Total annual cost: Premium + $257 deductible = $1,697-$2,417.

Best for: Frequent doctor visits, chronic conditions, prefer predictable costs.

Plan N (Lower Premium): Premium: $85-$125/month ($1,020-$1,500/year).

Additional costs: Part B deductible $257 + $20 copay per office visit + $50 copay per ER visit (waived if admitted).

Example: 10 doctor visits/year = $257 + $200 copays = $457 extra.

Total annual cost: $1,477-$1,957.

Best for: Healthy seniors, <6 doctor visits/year, willing to accept copays for lower premium.

Breakeven: If premium difference is $35/month ($420/year), need <21 office visits ($20 copay) + ER visits ($50) to make Plan N cheaper.

Most seniors have 8-12 visits/year = $160-$240 copays + $257 deductible = $417-$497 → Plan N saves $0-$200/year.

Plan F (Closed to new enrollees): Only available if enrolled before 2020.

Covers Part B deductible + excess charges.

Premium: $180-$250/month.

Existing Plan F members: Stay if premium <$40/month more than Plan G (saves $257 deductible annually). 2025 recommendation: Plan G for simplicity + comprehensive coverage.

Plan N for healthy seniors wanting to save $200-$500/year.

Plan C/F grandfathered members should stay (cannot re-enroll if switch).
