Ever woken up with a hip that feels like it's grinding glass every time you take a step? Yeah. For a lot of folks over 65, that's not a hypothetical — it's Tuesday.
So the question comes up fast once the pain stops being manageable: does Medicare pay for hip replacement? But "usually" hides a pile of details that can cost you thousands if you miss them. Short answer — yes, it usually does. And honestly, this is the part most guides get wrong.
What Is Medicare Coverage for Hip Replacement
Look, Medicare isn't one thing. Day to day, it's a few parts stitched together, and each part handles a different slice of a hip replacement. The surgery itself, the hospital stay, the rehab, the walker they hand you on the way out — all of it falls under different rules.
Here's the thing — Original Medicare is made of Part A and Part B. Also, part A is your hospital insurance. Part B is your medical insurance for doctors and outpatient stuff. If you've got a Medicare Advantage plan (that's Part C), you're still covered for the same basics, but the network and copay math change Still holds up..
Original Medicare: Part A and Part B
Part A picks up the inpatient side. The surgery happens in a hospital, you stay a couple days — that's Part A territory. It covers the room, the nursing, the operating room, and most of the hospital bill.
Part B covers the surgeon. The anesthesiologist. Which means the pre-op X-rays and the office visits where they tell you yeah, it's time. It also covers some of the durable medical equipment — think a walker or a raised toilet seat — if your doctor writes it as medically necessary.
Medicare Advantage (Part C)
These are private plans that bundle Part A and B, sometimes with drug coverage. Worth adding: they have to cover hip replacement the way Original Medicare does, by law. But they'll route you through their own network. Miss that network and the bill looks very different.
Medigap
This isn't a separate coverage for surgery — it's the sidekick that pays the leftovers. If Part A and B leave a 20% coinurance or a deductible, a Medigap policy can swallow a lot of it. Worth knowing if you hate surprise bills Not complicated — just consistent..
Why It Matters / Why People Care
Why does this matter? Because most people skip the fine print and assume "Medicare covers it" means "I pay zero." That's not how it works in practice.
A hip replacement in the US runs somewhere between $30,000 and $50,000 before insurance touches it. Medicare knocks that down hard — but you can still owe deductibles, coinsurance, and out-of-pocket for things like private rooms or out-of-network rehab. I know it sounds simple — but it's easy to miss the gap between "covered" and "free Surprisingly effective..
And the rehab piece? Real talk: the surgery is half the battle. You might sail through surgery only to find the skilled nursing facility near you doesn't take your plan, or your stay runs past what Medicare pays for. In practice, that's where people get burned. The recovery billing is the other half Worth knowing..
How It Works (or How to Do It)
Turns out the process has a rhythm. If you know the steps, you can dodge most of the money surprises.
Step 1: Confirm Medical Necessity
Medicare doesn't pay for elective cosmetic anything. Worth adding: no documentation, no coverage. Your orthopedist documents the pain, the failed physical therapy, the imaging. A hip replacement has to be deemed medically necessary — usually from osteoarthritis, a fracture, or bone death. Simple as that And that's really what it comes down to. Surprisingly effective..
Step 2: Understand the Part A Hospital Stay
Once you're admitted as an inpatient, Part A covers up to 90 days per benefit period. Day to day, for 2024, the deductible is $1,632. After that, days 1–60 are $0. Days 61–90 cost a daily coinsurance (around $408). Most hip replacements don't eat 60 days — typical stay is one to three nights — but the deductible still hits Nothing fancy..
Step 3: Know What Part B Pays For
Part B covers the doctor bills. You pay the annual deductible (about $240) and then 20% of the Medicare-approved amount for the surgeon and outpatient services. Worth adding: the approved amount is way lower than the hospital's sticker price, so that 20% is usually manageable. But it's not nothing.
Step 4: Durable Medical Equipment
That walker, the crutches, the cane — if a Medicare-enrolled supplier provides them and your doc prescribes them, Part B covers 80%. You pay 20%. Here's the thing — here's what most people miss: if you buy the walker at a retail store without going through an enrolled supplier, Medicare won't reimburse you. The system wants the paper trail.
Step 5: Skilled Nursing and Rehab
After surgery, if you need skilled nursing care, Medicare Part A covers up to 100 days — but only if you were an inpatient for at least three consecutive days and you go to a Medicare-certified facility. First 20 days are fully covered. Days 21–100 have a daily copay (around $204). After 100 days, you're on your own or your supplemental plan's Easy to understand, harder to ignore..
Step 6: Outpatient Physical Therapy
Once you're home, outpatient PT falls under Part B. There's no annual limit on medically necessary therapy anymore, which is good news. You still pay 20% of the approved rate.
Common Mistakes / What Most People Get Wrong
The short version is: people confuse "observation status" with "inpatient.That said, " If the hospital keeps you for monitoring but labels you observation, Part A doesn't kick in the same way. That three-day inpatient rule for rehab? Think about it: observation nights don't count. So you could owe the whole skilled nursing bill because of a paperwork label. Ask the hospital social worker point-blank: "Am I inpatient or observation?
Easier said than done, but still worth knowing.
Another miss — assuming Medicare Advantage means the same costs as Original Medicare. It covers the surgery, sure. But you might need prior authorization. In real terms, skip it and the plan can deny the claim entirely. Not reduce it. Deny it.
And don't forget the surgeon's assistant or the hospital's facility fee if you have the surgery at an outpatient surgical center. Part B covers it, but the math shifts. Some centers are owned by the hospital, some aren't. The bill shows up differently Not complicated — just consistent..
Oh, and the private room request. Want a single room because you hate sharing? Practically speaking, medicare pays for semi-private. You pay the upgrade. Easy to forget when you're signing forms pre-surgery.
Practical Tips / What Actually Works
Here's what I'd tell my own mom. Sounds basic. First, call 1-800-MEDICARE or use your plan's online tool to confirm the hospital and surgeon are in-network. Most people don't do it.
Second, ask for a written estimate of your out-of-pocket before the surgery. The hospital has to give one under the No Surprises Act for scheduled care. Here's the thing — use it. Compare it against your Medigap or Advantage plan summary Less friction, more output..
Third, if you're on Original Medicare without Medigap, look into a supplement before the surgery if you're still in your open enrollment window. It can turn a $3,000 coinsurance bill into $0. Timing matters — you can't always buy one later without medical underwriting.
Fourth, line up your rehab before you go under. Know which skilled nursing facilities near you take your plan and have a bed. The hospital discharge planner is overwhelmed; you being ready makes your life easier.
Fifth, keep every piece of paper. Billing errors are common. Day to day, i've seen people charged twice for the same surgical tray. The Medicare Summary Notice, the EOB from your Advantage plan, the supplier receipt for the walker. Check the notices like you'd check a restaurant bill.
FAQ
Does Medicare pay for a hip replacement if I have a Medicare Advantage plan? Yes. By law it must cover the same services as Original Medicare. But you'll likely need prior authorization and must use in-network providers to avoid big out-of-pocket costs Simple as that..
How much does Medicare pay toward hip replacement surgery? Medicare pays the large majority of the Medicare-approved amount. You're responsible for Part A and B deductibles and 20% of Part B services unless you have Medigap or a plan that covers cost-sharing.
Will Medicare cover my hip replacement at a surgery center instead of a hospital? If
the center is Medicare-certified and your doctor accepts Medicare assignment, yes — but the facility fee structure differs from a hospital setting, and your plan may require prior authorization or restrict coverage to certain approved centers. Always verify the center's status and your plan's network rules before booking.
What if I need physical therapy after the surgery? Medicare Part B covers outpatient physical therapy when it's medically necessary and ordered by your physician, subject to the annual therapy threshold and your usual cost-sharing. If you receive therapy in a skilled nursing facility during a qualifying inpatient stay, it's bundled under Part A instead.
Can my supplement plan deny my claim for the surgery? A standardized Medigap policy must cover its share of Medicare-approved charges once Medicare processes the claim. It doesn't deny based on prior authorization — but it also won't pay amounts Medicare doesn't approve, such as non-covered comfort upgrades That's the part that actually makes a difference..
The Bottom Line
A Medicare-covered hip replacement is never just one line item. Original Medicare with a Medigap policy offers the most predictable path; Medicare Advantage can save you on premiums but shifts risk to you through network rules and authorizations. Worth adding: either way, the patients who come out ahead are the ones who confirmed coverage in writing, requested estimates, and tracked every statement. Between deductibles, coinsurance, facility choices, prior authorization, and the small upgrades people forget to question, the real cost depends almost entirely on the plan you have and the steps you take beforehand. Do that, and the surgery — not the bill — stays the focus Worth knowing..
