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.

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 Maryland
Maryland's healthcare costs run approximately 13% above the national average, driven by the state's affluent demographics and concentration of prestigious medical institutions. The state's unique hospital rate-setting system provides cost transparency but can result in higher baseline pricing compared to market-driven states.
Urban vs. Rural Provider Availability
The Baltimore-Washington corridor contains the majority of Maryland's orthopedic specialists, with over 60% of knee replacement surgeons practicing within 30 miles of these metropolitan areas. Rural counties on the Eastern Shore and Western Maryland face significant access challenges, often requiring patients to travel 1-2 hours for specialized orthopedic care. This geographic disparity creates cost variations as rural patients may need to use higher-priced academic medical centers due to limited local options.
Facility Type and Overhead Costs
Hospital-owned orthopedic practices in Maryland typically charge 25-50% more than independent surgery centers due to higher administrative overhead and facility fees. Major health systems like Johns Hopkins, University of Maryland, and MedStar dominate the market, often commanding premium pricing due to their reputation and teaching hospital status. Ambulatory surgery centers and independent orthopedic groups generally offer more competitive pricing while maintaining comparable quality outcomes.
Insurance Market Competition in Maryland
CareFirst BlueCross BlueShield maintains approximately 50% market share in Maryland, with UnitedHealthcare and Aetna providing additional competition primarily in employer group markets. This relatively concentrated market gives major insurers significant negotiating power with providers, but can limit patient choice in terms of network options. The state's rate-setting authority for hospitals adds another layer of price regulation that affects orthopedic facility costs.
Physician Supply and Demand in Maryland
With nearly 4,000 active providers performing knee replacement procedures, Maryland has a robust supply of orthopedic specialists relative to its population of 6.1 million residents. This healthy provider-to-patient ratio helps contain costs and reduces wait times for non-emergency consultations to typically 1-3 weeks. The presence of multiple residency and fellowship training programs ensures a steady pipeline of new specialists entering the Maryland market.
