Knee Replacement Cost in the USA: Hospital Cash Price, Insurance and Medicare
What US hospitals publish as their cash price for a total knee replacement, the spread of rates they negotiated with insurers, and what Medicare pays a surgical center and a surgeon, per billing code and with the file each figure was read from. The inpatient stay is not priced.
What is priced: The inpatient stay is not priced here. When a joint replacement is done as an inpatient stay, hospitals price the stay as a whole under an inpatient case group, not under this billing code, and those figures are not read. The hospital figures on this page are the lines hospitals list under this code that are not marked inpatient-only; a line may be marked for both settings.

Important information for US visitors
This page is general consumer information about published US hospital charges and Medicare fee schedules. It is not insurance advice, billing advice, legal advice, tax advice, or medical advice. The calculator does arithmetic on numbers you enter; an actual bill depends on your plan, network status, prior authorization, separate professional and facility fees, and the code billed. Check any quoted price and your share with your provider and your insurer before booking care.
Could paying cash for a knee replacement cost less than using insurance?
It can. Compare the provider’s written cash quote with your own share under your plan (deductible left, coinsurance, copay, out-of-pocket limit), not with the hospital’s gross charge. For code 27447, the median hospital cash price in the files read is $15,153 across 17 hospitals.
How each route pays for a Knee replacement
One billing code, 27447 (Total knee replacement), so every figure prices the same service. Other codes are in the tables below. Waiting times are not published by any official US source.
| Route | What it covers | Wait | Price | Source |
|---|---|---|---|---|
| Original Medicare (Part B)Code 27447: Total knee replacement | After the Part B deductible, the patient usually pays 20% of the Medicare-approved amount.Where the provider accepts the Medicare-approved amount as full payment. The deductible is in the Medicare table below. | Not publishedNo official US source publishes waiting times for this procedure. | $9,393.16What Medicare pays. National rate paid to an ambulatory surgical center for the facility. The physician is paid separately (see the Medicare table). |

Hospital figures are facility charges from each hospital’s own file; the physician’s bill is separate. Medicare amounts are national, before geographic adjustment. The inpatient stay is not priced here. When a joint replacement is done as an inpatient stay, hospitals price the stay as a whole under an inpatient case group, not under this billing code, and those figures are not read. The hospital figures on this page are the lines hospitals list under this code that are not marked inpatient-only; a line may be marked for both settings.
Inpatient or outpatient
Different prices
An inpatient stay and an outpatient operation are billed differently. Only lines for the code that are not marked inpatient-only are shown here; a line may be marked for both settings.
Separate bills
Surgeon and facility
The surgeon, the facility and anesthesia can each bill separately.
Implant
Ask what is included
Ask whether the implant is inside the facility quote or billed as its own line.
What hospitals publish for a Knee replacement, by billing code
Read from each hospital’s standard-charge file, which federal rules (45 CFR 180.50) require it to publish. One figure per hospital and code, the hospital’s facility charge. A median is given only where at least 4 hospitals publish; below that each hospital is named with its own figure. Cash prices and negotiated rates are never combined, and no insurer is named.
76 of 238 hospitals in our source registry for the US publish a figure for these codes in the files read.
Across all procedures: 183 of 238 hospitals, 51 of 51 states.
| Code | Hospital cash price | Hospital negotiated rates | What Medicare pays (national) |
|---|---|---|---|
| 27447Total knee replacement | Median $15,15317 hospitals; lowest $3,270, highest $58,035 | Median $14,28271 hospitals; lowest $3,262, highest $67,753 | $9,393.16Surgical center facility rate |
The negotiated figure for each hospital is the middle of the rates it lists across its payers. It is what an insurer pays the hospital, not what a patient on that plan pays. The lowest and highest figures are single hospitals’ and are shown so they can be checked against the file.

What Medicare pays for a Knee replacement
This is what Medicare pays under its national fee schedule, before geographic adjustment. It is not a price charged to patients or to anyone without Medicare.
| Code | Surgical center facility rate | Physician, in a facility | Physician, in an office |
|---|---|---|---|
| 27447Total knee replacement | $9,393.16 | $1,159.35 | No national amount |
Physician amounts: CMS Physician Fee Schedule, relative value file RVU26D, released August 26, 2026, read October 26, 2026. Computed by CMS’s formula with the file’s own conversion factor, before geographic adjustment.
Surgical center rates: CMS ambulatory surgical center rates, Addendum AA (October 2026), effective October 1, 2026, read October 26, 2026.
Not shown: what Medicare pays a hospital outpatient department. CMS publishes those rates (October 2026 Addendum B) only behind the AMA CPT licence agreement, which this site has not accepted; last checked November 6, 2026.
NOTE 3: The Medicare program payment is 80 percent of the total payment amount and beneficiary coinsurance is 20 percent of the total payment amount except for most preventive services. Sections 4104 and 10406 of the Affordable Care Act (ACA) waive coinsurance and the Part B deductible for most preventive services. These preventive services are identified with a double asterisk (**). (CMS, Addendum AA, quoted as published.)
The patient’s share under Original Medicare
Original Medicare Part B has an annual deductible, paid once a year before Medicare starts to pay. It is $283 (Calendar year 2026). CMS: 2026 Medicare Parts A & B Premiums and Deductibles, read October 26, 2026.
After the Part B deductible, the patient usually pays 20% of the Medicare-approved amount for each covered service, where the provider accepts that amount as full payment. Medicare.gov: Medicare costs, read October 26, 2026.
Arithmetic, not a bill: 20% of the national surgical center rate for code 27447 ($9,393.16) is $1,878.63, before geographic adjustment and the deductible, and excluding the physician’s separate bill.
Medicare Advantage plans set their own cost-sharing; this site does not name or price any plan. Plan choice is explained on Medicare.gov.
Paying yourself: the Good Faith Estimate
Providers and facilities must give uninsured and self-pay patients a Good Faith Estimate of expected charges when a service is scheduled or on request.
“This section sets forth requirements for health care providers and health care facilities related to the issuance of good faith estimates of expected charges for uninsured (or self-pay) individuals (or their authorized representatives), upon request or upon scheduling an item or service.”
Ask for the estimate in writing when you book, and ask whether it covers the separate physician, radiology, anesthesia and pathology bills.
eCFR: 45 CFR 149.610, In force (45 CFR 149.610, text as of 2026-10-01), read October 26, 2026.

Cash quote or insurance share for a Knee replacement?
Enter the quote you were given and your own plan figures. Every field starts empty: the tool uses only what you type, or a sourced figure you choose to copy in.
- Median hospital cash price, code 27447 (US): $15,152.74 (17 hospitals, facility charge only). every hospital and its file, read November 6, 2026.
- Median hospital negotiated rate, code 27447 (US): $14,282.17 (71 hospitals, facility charge only; your plan's own rate may differ). every hospital and its file, read November 6, 2026.
Enter a cash quote and your plan’s allowed amount to see the comparison.
The insurance share is the deductible still to pay (up to the allowed amount), plus your coinsurance on the rest, plus any copay, capped at the out-of-pocket limit you entered. It does not check network status, prior authorization, separately billed physician, radiology, anesthesia or pathology fees, or whether a cash payment counts toward your deductible.
Help the dataset
A written quote or an explanation of benefits you have received helps other readers. Useful submissions include billing code, facility charge, professional fee, provider name, date quoted and whether the amount was a cash price, an allowed amount, your share on an explanation of benefits, or a billed charge.
Before booking, ask
Provider
- What billing code will be used for this Knee replacement?
- Is the cash quote complete, or are professional or facility fees separate?
- Is contrast, anesthesia, pathology or follow-up included if relevant?
- Can you provide the quote in writing before booking?
- Will the operation be billed as inpatient or outpatient?
- Which billing code will be used?
Insurer
- Is the provider in-network for my exact plan?
- Will this billing code require prior authorization?
- What patient responsibility do you estimate after deductible, copay and coinsurance?
- If I pay cash, can I submit a claim afterwards, and would it count toward my deductible?

What changes a Knee replacement bill?
The useful comparison is itemized. These are the fields to pin down before relying on any quote.
| Factor | Why it matters | What to ask |
|---|---|---|
| Inpatient or outpatient | A stay admitted as inpatient is priced as a whole case, not under this code; an outpatient operation is priced under the code. | Ask whether the operation is planned as inpatient or outpatient, and for a written quote for that setting. |
| Implant | The implant can be part of the facility charge or a separate line. | Ask whether the implant is included in the facility quote. |
| Surgeon professional fee | The surgeon usually bills separately from the facility. | Ask whether the quote includes the surgeon fee and the facility fee. |
| Anesthesia billing | Anesthesia is typically billed separately; its network status can differ. | Ask whether anesthesia is included and whether the anesthesia provider is in network. |
| After the operation | Physical therapy and follow-up visits are billed on their own. | Ask which visits after the operation are inside the quote. |
Hospital outpatient department
The operation at a hospital without an inpatient admission.
What to check: Hospital files list a facility charge separately from the surgeon.
Ambulatory surgical center (ASC)
A standalone outpatient surgery facility.
What to check: Anesthesia and surgeon fees may be billed separately.
Common Knee replacement billing codes
The code changes the comparison. Ask the ordering clinician or provider which code will be billed. Labels are our own plain-English descriptions.
| Code | What it is | When it is used |
|---|---|---|
| 27447 | Total knee replacement | Replacement of the knee joint, both sides of the joint. |
Questions to ask before booking
- Will the operation be billed as inpatient or outpatient?
- Which billing code will be used?
- Are surgeon, facility, implant and anesthesia all included in the quote, or billed separately?
- Is the anesthesia provider in network?
- Which physical therapy and follow-up visits are included?
- If I pay cash, will the payment count toward my deductible or out-of-pocket limit?
- What is my estimated patient responsibility if billed to my insurance?
What these figures are not
- The inpatient stay is not priced here. When a joint replacement is done as an inpatient stay, hospitals price the stay as a whole under an inpatient case group, not under this billing code, and those figures are not read. The hospital figures on this page are the lines hospitals list under this code that are not marked inpatient-only; a line may be marked for both settings.
- A hospital’s discounted cash price is what that hospital charges a self-pay patient for the line it lists. It may not include the separately billed physician, radiologist, anesthesia or pathology fees.
- A negotiated rate is what one payer contracted with one hospital. It is not what a patient on that plan pays, which depends on the deductible, coinsurance, copay and network status.
- What Medicare pays is a national fee-schedule amount before geographic adjustment. It is not a price charged to anyone without Medicare.
Across 17 US hospital standard-charge files read on November 6, 2026, the median discounted cash price for code 27447 (Total knee replacement) was $15,153, as the hospital's facility charge. Each hospital's figure and file is listed on the TreatCompare page.
For the same code, the median of 71 hospitals' middle negotiated rates with insurers was $14,282. A negotiated rate is what the insurer pays the hospital, not what the patient pays.
Medicare's national payment amount for code 27447 is $9,393.16 (CMS ambulatory surgical center rates, Addendum AA (October 2026)), before geographic adjustment. It is not a price charged to anyone without Medicare.
