Exhibit C: Annotated Knee Replacement Bill, Line by Line

September 2026 9 min read cashmedical.co

This is the third exhibit in the Line Items series. It annotates a total knee replacement bill, one of the most common elective orthopedic procedures in the United States, with roughly 790,000 performed annually. For a self-pay patient, the total can range from $17,000 at a transparent-pricing ambulatory surgery center to $65,000 or more at a hospital outpatient department.

The bill, annotated

The table below represents a composite inpatient total knee replacement at a mid-size metro hospital. Figures are based on publicly reported chargemaster data, Surgery Center of Oklahoma published pricing, and the CMS Hospital Price Transparency MRF patterns. This is not a quote from a specific facility.

Total Knee Replacement - Single Joint, Inpatient, 2-Night Stay

Line ItemChargemasterCash-Pay RangeNote
Operating room time (2.5 hrs)$12,400$3,200 - $5,500SCO bundles this into one fee
Surgeon professional fee$6,800$3,000 - $5,000Separate bill from surgeon's practice
Anesthesia (general, 2.5 hrs)$4,200$1,500 - $2,800Often a third separate bill
Knee implant (cemented)$14,500$4,000 - $8,000Hospitals mark up 200-400%
Recovery room$3,600$800 - $1,500PACU time, usually 1-3 hrs
Room and board (2 nights)$8,200$2,400 - $4,800Semi-private standard
Physical therapy (inpatient, 3 sessions)$1,800$450 - $900Day-of and day-after mobilization
Pre-op labs and imaging$2,100$350 - $800CBC, metabolic panel, EKG, X-ray
Pharmacy (inpatient meds)$1,900$300 - $700Pain meds, antibiotics, blood thinners
Surgical supplies$2,400$400 - $900Drapes, dressings, drains
Blood bank (standby + possible transfusion)$1,200$200 - $600Type and screen, 2 units crossmatched
Total$59,100$16,600 - $31,500SCO all-inclusive: $17,679

↑ The chargemaster total of $59,100 is what an uninsured patient would be billed by default if they did not ask for the self-pay rate. The actual cash-pay range of $16,600 to $31,500 represents a 47% to 72% reduction, simply by asking.

What this bill leaves out

Even an itemized hospital bill for a knee replacement typically excludes several costs that arrive as separate bills weeks or months later:

The implant markup

The single largest discretionary markup on a knee replacement bill is the implant. The hospital purchases a cemented knee system from a manufacturer for roughly $2,000 to $4,000. The chargemaster price for the same implant is $14,500 in this example. Even the cash-pay range of $4,000 to $8,000 represents a 100% to 200% markup over acquisition cost.

This is why Surgery Center of Oklahoma prices its total knee replacement at $17,679 all-inclusive: by selling implants at cost rather than marking them up, the total drops dramatically. Patients who are comparing quotes should always ask whether the implant is included in the facility fee and what the markup is.
