Medigap plans pay what Original Medicare doesn't - deductibles, coinsurance, and copays. Coverage is standardized so a Plan G from one carrier covers the same as a Plan G from another. The difference is price and service.
Who this is for
- People who travel and want nationwide access
- Those preferring predictable monthly costs
- Beneficiaries who want freedom from networks
What you get
Standardized benefits
Plans A, B, C, D, F, G, K, L, M, N - same coverage across carriers.
Any provider that accepts Medicare
No network restrictions, no referrals.
Travel coverage rider
International emergency care available.
Guaranteed renewable
Coverage cannot be canceled if premiums are paid.
What Does a Medigap Policy Actually Pay For?
Original Medicare pays most of your hospital and medical bills, then hands you the rest. There is no yearly limit on that leftover share. A Medicare Supplement policy, usually called Medigap, steps in and pays most of it for you.
- The Part A hospital deductible, which applies per benefit period and can hit more than once in a year.
- The 20 percent coinsurance Part B leaves you on doctor visits, imaging, and outpatient surgery.
- Extra hospital days, after Medicare's own covered days run out.
- Skilled nursing coinsurance, after a qualifying hospital stay.
- Emergency care during foreign travel, on most plan letters, up to plan limits.
What a supplement does not do
A Medigap policy does not include drug coverage. You add a separate Part D plan next to it.
It also does not cover routine dental, vision, hearing, or long term care. Those are bought on their own.
Medigap benefits are standardized by law. A Plan G from one insurer covers exactly what a Plan G from another insurer covers. What changes is the premium, the rate history, and how the company treats you on the phone. That is why an independent comparison matters here more than almost anywhere else in insurance.
When Can You Buy One Without Health Questions?
This is the most important rule on the page. Most of the time, a Medigap insurer may ask about your health and turn you down. Inside a protected window, it may not.
Your protected windows
Medigap open enrollment
A one time, six month window that starts when you are 65 and enrolled in Part B. Any carrier must sell you any plan they offer, at their best health rating.
Guaranteed issue rights
Triggered by certain events, such as an employer plan ending, or your Advantage plan leaving the area. The rules are narrow, so confirm before you count on one.
The Medigap trial right
If you joined an Advantage plan at 65, you get a second chance. You generally have twelve months to drop it and take a supplement instead.
Losing Medi-Cal help
If Medi-Cal paid your premiums and that help ends, a guaranteed issue right may open for you.
The door can close quietly
Many people choose an Advantage plan at 65 to save money, then try to move to a supplement years later. That later application usually includes health questions.
The moment you most want a supplement is often the moment you are least likely to be approved. Choose your first road with that in mind.
What Is the California Birthday Rule?
California gives supplement holders something most states do not. Each year a window opens on your birthday. During it you may switch to another Medigap policy with equal or lesser benefits, without answering health questions.
- Who it helps. Anyone who already holds a Medigap policy and wants a better price or a different carrier.
- What it allows. A move to the same plan letter, or to one with fewer benefits, at your current rating.
- What it does not allow. A jump to richer benefits, or a move from an Advantage plan into a supplement.
- When it happens. The window opens on your birthday and stays open for a set number of days, so mark your calendar early.
Set a yearly reminder
We check your supplement rate every year, before your birthday. If another carrier sells the same coverage for less, the birthday rule may let you move with no medical questions. That one habit can save real money over a retirement.
How Do Plan G and Plan N Compare?
Most people shopping today land on Plan G or Plan N. Plan F is no longer sold to people who became eligible for Medicare after a cutoff set by Congress. A high deductible version of Plan G also exists, and it suits a smaller group.
Plan G and Plan N, side by side
Plan G
The most predictable choice.
- Monthly premium
- Higher of the two.
- Doctor visit copay
- None.
- Emergency room copay
- None.
- Part B deductible
- You pay it once a year. After that the plan covers your share.
- Excess charges
- Covered, if a provider bills above the Medicare rate.
- Best for
- People who want almost no bills after the yearly deductible.
Plan N
Lower premium, small copays.
- Monthly premium
- Lower than Plan G.
- Doctor visit copay
- A small copay at some office visits.
- Emergency room copay
- A copay that is waived if you are admitted.
- Part B deductible
- You pay it once a year, the same as Plan G.
- Excess charges
- Not covered. Most providers accept the Medicare rate, so this is rare.
- Best for
- People who see doctors less often and want a lower premium.
The math is simple. If the yearly premium savings on Plan N beat the copays you expect, Plan N wins. If you see specialists often, Plan G usually wins. Read the deeper breakdowns on Plan G and Plan N.
Why Do Medigap Premiums Go Up?
Benefits are fixed, so price is the whole battleground. Two policies with identical coverage can differ a lot in cost, today and ten years from now. How a carrier prices its policies matters as much as the quote in front of you.
Three ways carriers price a supplement
Community rated
Everyone with that plan pays the same, whatever their age. Increases come from claims and inflation.
Issue age rated
Your premium is based on your age when you bought the policy. It does not rise simply because you got older.
Attained age rated
Priced on your current age, so it climbs as you age. These often look cheapest at the start.
- Ask how often the carrier has raised rates in California, not nationwide.
- Ask whether a household or spousal discount applies to you.
- Ask whether the carrier is new to this market, or has served it for years.
- Never switch on price alone. First confirm you can qualify, or use the birthday rule.
The quote is the start, not the answer
A policy that is cheapest in year one can be the priciest by year five. We look at rate history and pricing method, then show you the likely path, not just today's number.
Is a Supplement the Right Fit for You?
A supplement usually fits
You may be a strong match if
- You want to keep your doctors, and add new ones, without checking a network.
- You split your time between Orange County and another state.
- You see specialists often, or you expect a procedure.
- You would rather pay a steady premium than face surprise copays.
- You are inside your Medigap open enrollment window right now.
Another road may fit better
An Advantage plan may serve you better if
- Your budget cannot absorb a second monthly premium.
- All of your doctors sit inside one local medical group.
- You value dental, vision, and hearing benefits built into the plan.
- You qualify for Medi-Cal help, which changes the math entirely.
We are an independent agency in Orange, and we quote 20+ A-rated carriers rather than push one. We can compare a supplement against an Advantage plan as full year totals, in person, by video, or by phone. When you are ready, contact us, or read how we work first.
What it costs
Medigap premiums are the main driver of what a supplement costs, and they differ by plan letter, carrier, age, and location. Because benefits are standardized, a Plan G covers the same care no matter which insurer sells it, so you are really shopping on price and service. Premiums generally rise over time, and how a carrier calculates increases matters as much as today's rate. Pairing a supplement with a standalone drug plan adds a second premium to budget for. A licensed agent can confirm current rates and rating methods for your area.
