I'm on Medigap Plan G, and I'm curious how my upcoming knee replacement surgery will be billed. Does the plan cover it all after my deductible?
Answered by 82 licensed agents
1. Original Medicare Pays First: First, Medicare determines if the knee replacement is medically necessary. If approved, Medicare pays its share of the Medicare-approved amount for the costs.
2 .Part A or Part B Coverage:
If the surgery is an inpatient procedure (requires an overnight hospital stay), Medicare Part A covers the hospital costs. Plan G will cover your Part A deductible and any coinsurance.
If the surgery is an outpatient procedure (most knee replacements are now outpatient), Medicare Part B covers the surgeon's fees, facility charges, and other related services. You are responsible for meeting the annual Part B deductible.
3. Medigap Plan G Pays Second: After Medicare pays its portion, your Medigap Plan G policy kicks in to cover the remaining costs (the "gaps"). Plan G covers the 20% coinsurance that Original Medicare leaves you responsible for once you meet the Part B deductible.
4. Minimal Out-of-Pocket Costs: Once you've paid your annual Part B deductible (which is $257 in 2025), Plan G covers 100% of all remaining Medicare-approved Part B charges and all Part A deductibles and coinsurance. This means your additional out-of-pocket expenses for the surgery and recovery should be minimal or non-existent, aside from your monthly Medigap premiums.
As long as the surgery is medically necessary and covered by Medicare, your out-of-pocket cost should generally not exceed the annual Part B deductible of $283 with a standard Medigap Plan G, or $2,950 if you have a high-deductible Plan G, assuming all providers accept Medicare assignment. If post-surgical rehabilitation in a Skilled Nursing Facility is medically necessary, Medicare typically requires a minimum 3-day inpatient hospital stay for that rehab stay to be covered. Once qualified, Medicare covers days 1–20 in full, and Plan G generally covers the remaining coinsurance for days 21–100.
Great question — here's how it works with Medigap Plan G:
Medigap Plan G covers everything that Original Medicare covers except the Part B annual deductible (which is $240 in 2025). So for your knee replacement:
1. Medicare Part A will cover your hospital stay and related inpatient costs.
2. Medicare Part B will cover the doctor fees, outpatient surgery costs, and physical therapy.
Once you've paid your $240 Part B deductible, Plan G pays 100% of the remaining Medicare-approved charges, including:
Hospital costs
Surgeon's fees
Anesthesia
Outpatient rehab
Durable medical equipment like a walker
So yes — after your deductible is met, your Plan G will cover the rest of the knee replacement surgery as long as it's Medicare-approved.
Medigap Plan G is a comprehensive supplement to Original Medicare (Parts A and B). It provides extensive coverage for various out-of-pocket costs that Medicare does not fully cover.
Medigap Plan G covers all costs not paid by Original Medicare except for the Medicare Part B deductible. In 2025, the Part B deductible is $257. This means that before Medigap Plan G begins to cover your knee replacement surgery, you will need to pay this deductible out of pocket, if you have already met the deductible for 2025 there will be no additional out of pocket expense for Medicare covered procedures.
The billing process for your knee replacement surgery will generally follow these steps:
• Your healthcare providers will submit claims to Medicare for the services rendered.
• Medicare will process the claims and pay its share of the approved amounts.
• The remaining eligible expenses will be forwarded to your Medigap Plan G insurer, which will then pay its share directly to the providers.
Once you have paid the Medicare Part B deductible, Medigap Plan G will cover the remaining costs of your knee replacement surgery, ensuring you have minimal out-of-pocket expenses. Always check with your healthcare provider and Medigap insurer to confirm specific coverage details and to understand exactly what to expect during the billing process.
Generally, as long as your charges are all medicare approved, once you pay your $283 part B deductible, you shouldn’t have to pay anything else for the remainder of the year.
Anything NOT covered by medicare - if you need custodial care in a skilled nursing facility (not covered) vs. inpatient rehabilitation (covered), for example, would be your responsibility.
But in most cases, once you’ve paid the deductible, you’re covered for the rest.
As long as the facility where you have the surgery accepts Medicare, you will only be responsible for the Part B annual deductible ($257 for 2025). Once you pay the Part B annual deductible, Medicare will pick up 80% of the remaining bill, and your Medigap Plan G will pick up the other 20%. Most knee replacements also require a hospital stay, so you may need to meet your Part A deductible also. After that you should not have any additional expenses.
With all Plan G plans, a member is responsible for the first $257 of the Part B deductible. As long as the procedure is approved by Medicare, the Plan G picks up the rest of the bill. A member is also responsible for the monthly Plan G premium and the Part B premium as well. All Part A is covered at 100% with a Plan G and there are no copays.
Since you're on Medigap Plan G, your knee replacement surgery will be very well covered.
Here's what to expect:
Hospital stays (Part A): If you're admitted as an inpatient, Medicare covers most costs, and Plan G covers the Part A deductible and coinsurance.
You pay $0 for the hospital stay.
Surgery, surgeon, anesthesia (Part B): These are billed under Part B. You’ll pay the $240 Part B deductible (for 2024) and then Plan G picks up the remaining 20% coinsurance.
You pay only the $240 deductible—nothing more.
Rehab and physical therapy: Whether done at home, outpatient, or in a facility, these are usually covered under Part B. Plan G will cover these costs after you meet the deductible.
In total:
As long as your providers accept Medicare, your only out-of-pocket cost for the entire surgery and recovery will be $240, the annual Part B deductible. After that, Plan G takes care of the rest.
You're in an excellent plan for major procedures like this. Let me know if you’d like help checking if your providers accept Medicare or reviewing expected costs!
If you’ve already met your deductible then you’re covered at 100%. If you have not met your deductible, then it will be covered after the deductible at 100%. If the facility you go to says “if you pay this much now, we cut this much off your bill”. Do not do this. Tell them to just bill the insurance. If you get a bill in the mail, don’t just pay it. Providers bill patients before insurance even knows they have a claim and it’s often more than you would owe if you hadn’t met your deductible. Call the company billing you. Tell them you have a Plan G and you won’t owe what they’re billing and wait for an Explanation of benefits before paying what would be your deductible assuming you have not already met your deductible. You’ll owe nothing if you’ve already met it.
Medigap Plan G covers 100% of all remaining Medicare-approved charges once you have paid your annual deductible for Part B. If you have already paid your deductible for the year, and you receive any bills, I strongly recommend contacting the billing department and making sure they billed Medicare & your medigap company. Generally, Medicare sends the claim information to the medigap company automatically. However, I find it's usually a good idea to make sure they have all of the applicable billing information for you.
With Original Medicare plus Medigap Plan G, your knee replacement surgery will first be billed to Medicare Part A (hospital stay) and Part B (doctor and outpatient services). Medicare pays its share, and then Plan G covers nearly all the remaining costs except the annual Part B deductible. Once you’ve met that deductible, Plan G generally covers the rest, leaving you with little to no out-of-pocket expense for approved services.
Yes! As a Plan "G" Supplement holder, as long as you continue to have original Medicare A and B, pay your Part B and your supplement premiums, your only obligation to medical bills will be the $257 Part B Deductible, and you should not see a bill again for the rest of the year regardless of any other medical needs, outside of Long Term Care. If you do not have an agent who can answer these questions, you should find one! That's what the Agent should be paid to do - service AFTER the sale!
You're exactly right! Once you've met your Part B deductible ($257 in 2025), your plan G will cover all remaining costs that Medicare approves but doesn't pay for. This is assuming you have a standard Plan G and not a high deductible Plan G.
Yes. As long as the facility where you have the surgery accepts Medicare assignment, you will only be responsible for the Part B annual deductible ($257 for 2025). Once you pay the Part B annual deductible, Medicare will pick up 80% of the remaining bill, and your Medigap Plan G will pick up the other 20%.
If the surgery is performed in an outpatient setting, you have to meet the Part B annual deductible ($283 in 2026). Once your deductible is met, Medicare pays 80% and your Plan G will cover the remaining 20%.
Yes. Generally, a Medigap Plan G will pay everything after you have met your Medicare Part B deductible, which for 2025 is $257. So the office will bill Medicare, and Medicare can see if you have already met your deductible or not. If not, you will owe the $257 first, and then your supplement will pay the rest.
If your knee replacement will occur as an Inpatient Hospital procedure, your plan G should bill Medicare under Part A and your Medigap Plan G, as such, will cover your Hospital Benefit Period Deductible with no out of pocket costs to you.
If the procedure will occur as an outpatient procedure under Part B, then you will be responsible for the $283 Part B Deductible. The remaining 20% coinsurance should be covered by your Medigap Plan G.
Thanks for asking!!...Your MediGap or Medicare Supplement SHOULD cover all or most of the cost of your knee replacement surgery. There should not be any copays associated with this procedure, as long as it is considered "medically necessary" and done by physicians that accept Medicare "Assignment". That means they accept what Medicare pays them for specific services and will not bill above and beyond that. A doctor can accept Medicare patients BUT not accept Medicare "assignment", meaning they can charge patients up to 15% above what Medicare pays them. Fortunately for you, Plan G PAYS the extra 15%, called Medicare "excess fees".
If your upcoming knee replacement was approved by Medicare then your Medicare Supplement Plan G will pay the 20% that Medicare does not cover after you have met your Part B annual deductible.
All Medicare approved services are covered under a Plan G after the annual deductible is met. Keep in my, Original Medicare Part A & Part B is your primary insurance and that is who the doctor/hospital bills first. The supplement pays the 20% of the cost that Medicare doesn’t pay for after the annual deductible. No surprise bills afterwards and the biggest take away is that there are NO prior authorization hurdles to jump over.
With Medigap Plan G, your knee replacement surgery will be covered by Medicare Part A and Part B first. Once you’ve met your annual Part B deductible ($240 in 2025), Plan G will pay the remaining approved costs — meaning you’ll have no additional out-of-pocket expenses for Medicare-approved services.
Medigap Plan G is a comprehensive plan and covers you if it is a Medicare approved charge. The best thing you can do for any surgery is to contact your carrier on your card and ask them to let you know what out of pocket charges you can expect. I can say that I know someone who got a knee replacement on Plan G and only paid the Part B deductible but always call your carrier first so that you know what to expect for sure.
The only out-of-pocket expense you should have on a Medicare Supplement Plan G, apart from your monthly premium, is your Part B Medicare annual deductible. After your annual Part B deductuble is met, anything hospital or doctor related is covered at 100%
With Medigap Plan G, you'll pay the Medicare Part B deductible and the 20% coinsurance on covered services, but the plan will then cover the remaining costs for your knee replacement surgery. Plan G essentially covers the "gaps" in Original Medicare coverage, helping with deductibles, coinsurance, and copayments.
Here's a more detailed breakdown:
Medicare Part B Deductible:
.
You'll need to pay the annual Medicare Part B deductible, which is $257 in 2025.
20% Coinsurance:
.
Medicare will pay 80% of covered services, and you'll pay the remaining 20% (your coinsurance).
Medigap Plan G Coverage:
.
Once you've met the deductible and paid your coinsurance, Medigap Plan G will pay the remaining costs for Medicare-approved services.
In essence, Medigap Plan G helps bridge the gap between Original Medicare's coverage and your overall healthcare costs. It covers the coinsurance and copayments that Original Medicare doesn't, and helps with deductibles.
For a more personalized explanation, it's always a good idea to consult with your Medigap insurer or a Medicare advisor to understand how Plan G specifically covers your situation.
On a Medigap Plan G, there is a $257 annual deductible that must be met before the plan will pay the remaining balance. You will receive a statement from Medicare indicating that you have either met your deductible or you have not met your deductible. If you have met the annual deductible, the plan pays the remainder for the rest of the year. If you have not met the deductible, you will need to pay the facility where the services occurred up to the amount of the deductible.
With Plan G, once you’ve met your Part B deductible for the year, Medicare pays its share first and your Medigap steps in to cover the rest of the approved costs. You shouldn’t see big surprise bills, but you may still have some charges if the surgeon or facility bills anything Medicare doesn’t approve.
Yes, Medicare Supplement Plan G will cover all Medicare-covered costs associated with a knee replacement, except for the Part B deductible. If the procedure is covered by Medicare and deemed to be medically necessary, your Medigap Plan G will cover all costs with the exception of your Medicare Part B deductible.
If you haven't paid your Part B annual deductible, you will be billed that amount. This year it is $257. If you HAVE paid your Part B deductible, you will likely not receive a bill. The provider will bill Medicare and your Plan G. There should not be any additional charges for that procedure.
Yes,- once you meet your annual Part B deductible ($240 in 2025), Medigap Plan G will cover all Medicare-approved costs for your knee replacement surgery. You'll owe nothing more for covered services.
Plan G is the most popular Medigap plan you can acquire. Remember that the ratio of 80/20% ALWAYS comes into play. Part A is for IN-patient hospital services. That's your Primary insurance, paying 80% while the balance of 20% will be paid by your Med. Supplement. Thus, here are your two theoretical examples: A) like the above, the knee surgery is performed in a hospital. Part A pays the 80% of all surgical charges while the Supplement picks up all the rest except for the one-time per year (!) Part B deductible of $257.00. If you already have met that amount, no additional funds are your responsibility. B) Though rare, if this same operation is done in an outside surgical center, (outpatient!) the 80% is paid by Part B and the remainder is again paid by the Medigap plan.
Yes it sure does. Since there are no networks, you should be covered 100% after your $283 deductible is satisfied. No copays with Plan G. If you receive a bill afterwards, contact your agent or the company you have the Plan G with to make sure they take care of it.
Yes, Medicare will cover medically necessary knee surgery after you meet your deductible. Medicare Original will cover a portion and the Plan G will pick up the remaining cost, essentially leaving you $0 out of pocket.
It should cover everything that is considered medically necessary. You have your part B deductible, and it should cover the 20% that original Medicare doesn't cover. Check and see if your state allows for balance billing. My state does not. Balance billing is when the doctor or facility charges more than is allowed by Medicare.
So when I came across this question, I definitely had to make a quick video because it's a pretty simple answer. The question is, I'm on a Medigap Plan G, and I'm curious how my upcoming knee replacement surgery will be billed. Does the plan cover it after all? Does a plan cover it all after my deductible?
The answer to that is yes. If you are getting this surgery done at a Medicare-approved facility and it is medically necessary, the only thing you have to pay for with a Medicare Plan G is a $283 deductible for this year. After that, you won't pay anything.
Basically that is correct. Any Part B service which will include a knee replacement or PT afterwards should be covered by your G plan, but the big piece here is if Medicare approves the service. If it's done experimental knee replacement, Medicare most likely will not approve that service and your G plan will not cover it. But for the most part, you really should not see any bills after your deductible for a knee replacement.
Ideally you should be check in to the facility in the morning and home by dinner. Including walking with a walker. Your Medicare part B ($283 Deductible) Which is not paid by plan G, then Medicare should pay 80% and Plan G will pay 20%. This includes the surgery center, Surgeons fees and the anesthesiologist. Some Surgeons use a robot new technology and that may not be covered by Medicare Part B and so your Supplement G will not be paying any of the as it is on out-of-pocket personal cost. If Medicare Does pay, then your supplement will of course supplement the balance.
Your plan G Medicare Supplement will pick up everything your Original Medicare does not pay for, expect the $283 medical deductible. That is your responsibility before your Plan G will pick up your remaining cost after your knee replacement surgery. If you have any further questions, I would be glad to assist you.

Medigap Plan G is a supplemental insurance and considered secondary insurance. The bill will generally go to the primary insurance first, which will be Medicare.

You will be responsible for any copays or deductibles.
