Important: These are cost estimates only — not a quote and not medical advice.
The prices on this page are self-pay rates, drawn from federal Transparency in Coverage machine-readable files (CPT 27447 — Total knee arthroplasty). They represent what a patient might pay without insurance.
Your actual cost depends on: your specific insurance plan, your remaining deductible, your coinsurance percentage, whether you have met your out-of-pocket maximum, whether the facility and provider are both in-network, and any separate anesthesia or implant fees billed independently.
This page does not constitute medical advice. Whether you need this procedure, and which approach is right for you, is a decision to make with a licensed healthcare provider.
Where this data comes from & what CPT 27447 covers
Data source: Cost figures are derived from UnitedHealthcare Transparency in Coverage machine-readable files for CPT code 27447 (Total knee arthroplasty), as mandated by the CMS Price Transparency Rule.
What CPT 27447 covers: the provider's professional fee for knee replacement. It does not include facility/hospital fees, anesthesia, pre-operative imaging, post-operative care, or any add-on codes billed separately.
How to read this data
Negotiated Rate
The discounted price an insurer has agreed to pay a specific provider. Most insured patients' bills are calculated from this number, not the higher list price hospitals publish separately.
P5, Median, P95
P5 is the rate at the 5th percentile (low end), Median is the middle value, and P95 is the 95th percentile (high end). This range shows how much the same visit can vary between providers.
What this does not tell you
These rates do not tell you what you personally will pay out of pocket. That depends on your specific plan, how much of your deductible you have already met, your coinsurance rate, and whether the provider is in your network. Call your insurer's member line to get your exact estimate.

Why Knee Replacement Surgery Visit Costs Vary Across Illinois
Illinois healthcare costs run approximately 10% above the national average, driven primarily by the concentration of high-cost academic medical centers in Chicago and the state's higher-than-average physician salaries. The stark contrast between urban and rural provider availability creates significant cost and access disparities across the state's diverse geographic regions.
Urban vs. Rural Provider Availability
The Chicago metropolitan area houses nearly two-thirds of Illinois's orthopedic surgeons, while rural counties in southern and western Illinois often have limited or no local Knee Replacement Surgery options. This geographic concentration forces many rural patients to travel significant distances for specialized care, though it also creates competitive pricing in urban markets. Telemedicine consultations have begun bridging some access gaps, particularly for post-operative follow-up visits.
Facility Type and Overhead Costs
Major health systems like Northwestern Medicine, Rush University Medical Center, and OSF HealthCare dominate Illinois's orthopedic landscape, with hospital-based practices typically charging higher facility fees than independent surgical groups. Academic medical centers in Chicago command premium pricing due to their research focus and complex case referrals, while community hospitals in smaller cities like Rockford or Champaign often offer more competitive rates. Ambulatory surgery centers throughout Illinois provide cost-effective alternatives for many orthopedic procedures compared to hospital-based facilities.
Insurance Market Competition in Illinois
Blue Cross Blue Shield of Illinois maintains the largest market share statewide, followed by UnitedHealthcare and Aetna, creating moderate competition that helps contain specialist costs in urban areas. Rural Illinois counties often have fewer insurance options on the individual market, potentially limiting network choices for Knee Replacement Surgery providers. The state's Medicaid managed care contracts with multiple insurers have increased competition for specialist networks, benefiting patient access and cost control.
Physician Supply and Demand in Illinois
Illinois has over 4,800 providers performing Knee Replacement Surgery procedures, indicating robust specialist availability that helps moderate pricing through competition. The concentration of orthopedic residency programs in Chicago creates a steady pipeline of new surgeons, though many migrate to suburban or out-of-state practices after training. This abundant supply in urban areas contrasts sharply with specialist shortages in rural regions, creating wait time and cost disparities across the state.
