What does a knee replacement cost in Connecticut?

You could pay $2,500 or $5,246 for the same knee replacement in Connecticut — depending entirely on which facility you choose. The median cash price across 17 reporting hospitals is $5,246. This data comes directly from hospital price transparency files published under federal law.

How prices are distributed across Connecticut hospitals:
  • Bottom 25% of hospitals: under $2,410
  • Median: $5,246
  • Above median (top 30%): $5,246+

That's a 2× spread for the same procedure — driven entirely by which facility you choose, not by clinical complexity.

  • Patient A (high-cost facility): ~$5,246
  • Patient B (lower-cost facility): ~$2,500
Same procedure. Same week. $2,746 difference.

Worth knowing: A small number of hospitals report very high prices above $9,500, which pulls the overall range wider than what most patients encounter. The typical range above is a better guide for planning.
Every hospital in this dataset offers a cash price — with a median of $5,246. If your deductible hasn't been met, always ask for the self-pay rate before scheduling.

What you'll actually pay — example scenarios

Your situation Estimated out-of-pocket
Deductible not yet met (pay in full) ~$5,246
Deductible met — 20% coinsurance ~$1,049
Out-of-network provider $11,541+

Based on the state median of $5,246. Your actual cost depends on your plan deductible, coinsurance rate, and network tier. Get YOUR personalized estimate →

What this means for you

If you haven't met your deductible, you are effectively a cash-pay patient.

That means:

  • You should shop prices directly — the same way you'd compare any major purchase
  • Insurance may not get you a better deal than the cash price
  • The cheapest facility can save you $3,238+ vs. the median.

This is the single biggest lever most patients have to reduce their cost.

Lower-cost options in Connecticut start around $2,410 or below. Most hospitals cluster between $2,410 and $5,246. A smaller group reports prices above that — often academic medical centers or high-cost markets.

If you're comparing specific hospitals, the lowest self-pay rates reported in this dataset include: Norwalk Hospital in Norwalk (cash price from $2,008); Griffin Hospital in Derby (cash price from $2,128); Danbury Hospital in Danbury (cash price from $2,162). These are declared cash prices — contact each facility for a formal quote before scheduling.

Connecticut Knee Replacement prices by facility

All prices below come from hospital chargemasters — the official price lists each hospital must publish under federal law. Gross charge is the undiscounted list price; cash price is the self-pay rate; negotiated range covers the spread across insurance contracts.

How we calculate "Your Price" — We prioritize the most actionable price in this order:
  1. Cash price — the self-pay rate you can actually negotiate and pay
  2. Negotiated rate — if reported by the hospital across insurance contracts
  3. Gross charge — fallback only; this is the inflated list price few people pay

This reflects the real prices patients encounter — not inflated chargemaster rates.

Where you can save the most on knee replacement in Connecticut

These facilities have the lowest declared prices relative to the state median — they represent the best opportunities to reduce your out-of-pocket cost for this procedure.

Facility City Your Price vs Median
Norwalk Hospital Norwalk, CT $2,008 -$3,238
Griffin Hospital Derby, CT $2,128 -$3,118

How to choose a lower-cost facility

  • Choose independent outpatient centers when possible — freestanding ASCs (ambulatory surgical centers) consistently charge less than hospital outpatient departments for identical procedures.
  • Ask for the cash price if your deductible isn't met — self-pay rates are often lower than what insurance pays before your deductible is satisfied, especially at facilities that have a high cash-price discount.
  • Avoid hospital outpatient departments for routine cases — hospital-owned locations add a facility fee that freestanding centers don't charge, often adding $500–$1,500 to the same procedure.
Important: Many procedures are done at ambulatory surgical centers (ASCs) that are often 30–60% cheaper than hospital outpatient departments with the same clinical quality. Most ASCs are not in this hospital dataset — meaning your cheapest option may not even appear here. Ask your doctor if the procedure can be done at a freestanding ASC.

Most expensive knee replacement providers in Connecticut

These facilities report the highest prices for this procedure. Academic medical centers and specialty hospitals often top this list — their gross charges rarely reflect what anyone actually pays, but understanding the spread helps you negotiate.

Facility City Price vs Median
Stamford Hospital Stamford, CT $10,223 +$4,977
Prospect Manchester Hospital, Inc Manchester, CT $8,380 +$3,134
Prospect Rockville Hospital, Inc Vernon Rockville, CT $8,380 +$3,134
Prospect Waterbury, Inc Waterbury, CT $5,988 +$742
WINDHAM COMMUNITY MEMORIAL HOSPITAL INC Willimantic, CT $5,246 +$0

Why prices vary this much

A small number of hospitals (1) report very high prices above $9,500, which drives much of the overall price range. Excluding these, most facilities cluster in a significantly tighter band.

The spread comes from how each hospital sets its chargemaster (the undiscounted list price), what cash discounts it applies, and what rates it negotiates with each insurer. Facility classification matters too — a hospital-owned outpatient center adds a facility fee that a freestanding clinic does not. Understanding these mechanics is the first step to paying less.

How insurance changes what you actually pay

Hospital list prices are only part of the picture. What you pay out of pocket depends on your deductible, your plan's out-of-pocket maximum, whether the facility is in-network, and whether your plan classifies the visit as outpatient or inpatient. A lower gross charge doesn't guarantee a lower bill if the facility is out-of-network or adds facility fees your plan doesn't cover.
