Knee Replacement Cost in Chattanooga, TN
A total knee replacement is a surgical procedure in which a surgeon removes damaged surfaces of the knee joint and fits artificial components in their place. It produces a reconstructed joint rather than images or test results. The hospital facility fee covers the operating room, nursing, the hospital stay or recovery area, supplies and standard equipment, while surgeon and anesthesia services are billed separately. This page covers one billing code, 27447 Total Knee Replacement (Arthroplasty), at 4 hospitals in Chattanooga, TN. All prices come from the price transparency files that CMS requires hospitals to publish.

What These Prices Mean
A gross charge is a hospital's full list price before any discounts. A cash price is what a person without insurance, or paying outside insurance, may be asked to pay. An insured range shows the lowest and highest negotiated rates with health plans. On this page, all 4 rows have a missing gross charge, and 0 of 4 rows have a published cash price, so no cash-to-gross percentage can be given. Only the insured ranges are available. People on a high-deductible plan who have not yet met the deductible usually pay the plan's negotiated rate, so those insured figures are the most relevant numbers here.
One code, four rows
The page lists a single code, 27447 Total Knee Replacement (Arthroplasty), so there are no code-to-code comparisons to make. The same code appears at each of the 4 hospitals. The insured range is $167 to $21,668.58 at CHI Memorial Hospital Chattanooga and CHI Memorial Hospital Hixson, and $1,150 to $37,269 at Parkridge East Hospital and Parkridge Medical Center.
Why Knee Replacement Prices Vary
The 4 hospitals belong to 2 health systems, with 2 hospitals each: CHI Memorial (CommonSpirit) and HCA Parkridge. Within each system the two hospitals show identical insured ranges. Gross and cash ranges cannot be compared because none of the 4 hospitals published a gross charge or a cash price for this code, and 0 of 4 hospitals publish cash equal to gross. The lowest insured rate in the table is $167 at CHI Memorial Hospital Chattanooga, and the highest is $37,269 at Parkridge East Hospital.
Beyond these four hospitals
Outpatient surgery centers and other facilities outside this dataset may price a knee replacement differently, and their prices are not shown here. Plan-to-plan variation is visible at Parkridge Medical Center, where 95 published rates for 27447 run from $1,150 (Peach State and Wellcare Medicaid plans) to $37,269 (BCBS NetworkP). The highest is about 32x the lowest in that table.
Paying cash? Health insurance could lower your Knee Replacement cost.
Published cash prices on this page range from N/A to N/A. The lowest insured rate in the price table is $167 (CHI Memorial Hospital Chattanooga). Insured rates depend on the plan, and the lowest are often Medicaid, CHIP or Medicare Advantage plans, so they may not reflect what a commercial or marketplace plan pays. If you are uninsured, a marketplace health plan could reduce your out-of-pocket cost for this procedure.

What to Do With These Knee Replacement Prices
Quote the code when you call. Ask each hospital's billing office for its cash or self-pay price for CPT 27447 (total knee replacement), and request an itemized estimate in writing. Ask what the quote includes and excludes, and whether the stay would be billed as inpatient or outpatient.
Check the gaps before comparing. On this page, none of the 4 hospitals shows a cash price, and the gross charge is missing for all 4 rows. Those blanks are missing data, not a free service, so a phone call is the only way to get a cash figure. Once you have one, compare it with the insured range: $1,150 to $37,269 at Parkridge East Hospital and Parkridge Medical Center, and $167 to $21,668.58 at the two CHI Memorial campuses. The spread is wide because rates vary by insurer, so look at the insurer line that matches your plan rather than the full range.
Expect more than one bill. The prices here are facility charges only. Ask whether these can be billed separately:
- The surgeon's professional fee
- The anesthesia provider
- The implant or supplies, if not part of the facility charge
- Physical therapy and other follow-up care
Ask about bundles. Some hospitals offer a package price covering several of these items. If one is offered, ask for a list of what is in it and what is not, then match that list against the itemized bill when it arrives.
Financial assistance and discounts. Nonprofit hospitals are required to publish a financial assistance policy, and the billing office can send it with an application. Some hospitals also offer prompt-pay or self-pay discounts; these vary by hospital and are not included in this data. If you are uninsured or not using insurance for scheduled care, you can ask the provider for a good faith estimate before the appointment.

What Patients Ask About Knee Replacement Costs
How much does a knee replacement cost without insurance in Chattanooga?
No cash price for a knee replacement is published at any of the 4 Chattanooga hospitals on this page, so a self-pay range cannot be given. CHI Memorial Hospital Chattanooga, CHI Memorial Hospital Hixson, Parkridge East Hospital and Parkridge Medical Center all show cash as not published, which is treated as missing data rather than a real price. Gross charges are also missing for all 4 rows. Without insurance, you would need to ask each hospital for a written estimate. Surgeon, anesthesia and other professional fees are billed separately from the facility charge and are not included in these figures.
Why is the gross charge so much higher than the cash price?
On this page the comparison cannot be made, because the gross charge is missing for all 4 rows and no cash price is published for any of them. A cash-to-gross percentage is therefore not available for CHI Memorial Hospital Chattanooga, CHI Memorial Hospital Hixson, Parkridge East Hospital or Parkridge Medical Center. In general, a gross charge is a list price that few people pay in full, while cash and insured prices are set through discounts or contracts. Since both the gross and cash figures are missing here, only the insured ranges can be used for reference.
Does insurance cover a knee replacement?
Whether a knee replacement is covered depends on your specific plan, so the plan itself or your insurer is the place to confirm that. What the files show is the negotiated facility rate. At CHI Memorial Hospital Chattanooga and CHI Memorial Hospital Hixson the insured range is $167 to $21,668.58. At Parkridge East Hospital and Parkridge Medical Center it is $1,150 to $37,269. If you have a high-deductible plan and have not met your deductible, you usually pay the plan's negotiated rate for the facility charge.
Are there additional fees beyond the knee replacement facility charge?
Yes. The facility charge covers the hospital's costs, but other bills commonly come separately. These typically include the surgeon's professional fee, the anesthesiologist's fee, and charges from a pathologist or radiologist if their services are used. Separate bills may also arrive for implant or device vendors in some arrangements, physical therapy, follow-up visits, prescription medications and durable medical equipment such as a walker or brace. Pre-operative lab work and imaging may also be billed on their own. Ask each provider for an itemized estimate.
What is the cash price for knee replacement at Parkridge Medical Center in Chattanooga?
