Medigap Plan N is a standardized Medicare Supplement letter sold in most states. It helps with many Part A and Part B cost-sharing amounts after Original Medicare pays its share—but unlike Plan G, Plan N typically leaves you with up to a $20 copay for some office visits and up to a $50 copay for emergency-room visits (waived if you are admitted as an inpatient under Medicare’s rules). Plan N also generally does not cover Part B excess charges in states where providers can bill them. Monthly premiums are often lower than Plan G; you trade premium savings for those copays and excess-charge risk.

Plan N vs Plan G (typical standardized contrast)
| Feature | Plan G (typical) | Plan N (typical) |
|---|---|---|
| Part B deductible | You pay the annual Part B deductible | You pay the annual Part B deductible |
| Part B coinsurance after deductible | Usually covered | Usually covered except office-visit / ER copays below |
| Office visits | No Plan N-style copay on the letter chart | Up to $20 copay for some doctor visits (confirm outline) |
| ER visits | No Plan N-style copay on the letter chart | Up to $50 ER copay; often waived if admitted (confirm outline) |
| Part B excess charges | Usually covered where excess charges exist | Generally not covered—prefer participating / non-participating rules carefully |
| Premium | Higher | Often lower |
| Best fit (educational) | Want fewer per-visit surprises; live where excess charges matter | Willing to budget copays; use participating providers; strong cash buffer |
Massachusetts, Minnesota, and Wisconsin use different Medigap systems. Always compare same-letter quotes from UnitedHealthcare, Humana, Aetna, Mutual of Omaha, and Blues affiliates on Medicare.gov and insurer sites. Copay dollar caps on Plan N are set in the standardized benefit chart—confirm the current outline of coverage rather than memorizing old numbers.
How Plan N copays behave in practice
- Original Medicare pays first under Part A/B rules; Plan N then helps with many remaining amounts on the letter chart.
- You still pay the Part B deductible each year before many Part B Medigap benefits apply (Part B deductible basics).
- After that, some office visits can leave a Plan N copay (commonly up to $20) even when coinsurance is otherwise covered.
- An ER visit can leave a Plan N copay (commonly up to $50) unless admission rules waive it—read your outline.
- Premium vs deductible / copay tradeoffs in plain language: Premiums vs deductibles.
- You cannot pair Medigap with Medicare Advantage; MOOP math is a different product family.
Worked example: $40/month premium gap vs visit copays
Sam is 65, on Original Medicare in a state with standardized letters, shopping during Medigap open enrollment:
- Plan G: $175/month ($2,100/year) from a Humana affiliate (illustrative).
- Plan N: $135/month ($1,620/year) from a UnitedHealthcare affiliate; outline lists up to $20 office-visit and $50 ER copays.
Quiet year: Four specialist visits after the Part B deductible → about $80 in Plan N office copays. Plan N total ≈ $1,620 + $80 = $1,700 plus the Part B deductible Sam would pay under either letter. Plan G total ≈ $2,100 plus the same Part B deductible. Plan N can win on cash if visits stay light and providers accept assignment (no excess charges).
Busier year: Twelve office visits ($240 copays) plus one ER trip not admitted ($50) → $290 copays. Plan N stack ≈ $1,620 + $290 = $1,910 vs Plan G’s $2,100 premiums—still close—until a non-participating specialist adds Part B excess charges Plan N does not cover. In that year Plan G’s excess-charge help can flip the math. Sam picks based on expected visit count, ER risk, provider networks, and emergency-fund size—not the lowest premium alone.
Practical habits
- Pull same-letter quotes for Plan G and Plan N from at least three issuers during OE when you can.
- Write down Plan N’s office and ER copay language from the outline of coverage.
- Ask whether your regular doctors accept Medicare assignment (excess-charge exposure).
- Stress-test a quiet year and a visit-heavy year against your cash reserves.
- Enroll in Part D separately if you keep Original Medicare + Medigap.
- Buy only through licensed channels; Medigap phishing scripts exist alongside real SHIP counseling.
Checklist
- Confirm Original Medicare (not Advantage) before shopping Plan N or Plan G.
- Compare premiums for the same letters in your state.
- Record Plan N copay amounts and excess-charge treatment on the outline.
- Count expected office and ER visits against the premium savings vs Plan G.
- Calendar Medigap open enrollment or document another guaranteed-issue right.
- Keep outlines of coverage and premium quotes with your Medicare card copies.
