Quick take
- York Hospital is the lowest-cost option at $2,226 - $154 below the state median, just by choosing where you go.
- Ask for the cash price if your deductible isn't met - the median cash price here is $2,380, and it's often lower than what insurance pays before your deductible is satisfied.
- This dataset covers hospitals only - freestanding ASCs, which routinely run 30-60% cheaper for the same procedure, aren't included, so it's worth asking your doctor whether one is an option.
MaineHealth is the dominant system and covers most of Maine's hospital capacity, creating a largely non-competitive market outside Portland. Maine's extensive rural hospital network includes many critical access facilities where cost-based Medicare reimbursement applies. Northern Maine is one of the most medically isolated regions in the Eastern US. Knee replacement is a high-cost elective procedure where facility selection has an outsized impact on total cost. Hospital outpatient and ambulatory surgery center rates for knee replacement have converged on outcomes but diverged further on price - ASC rates are typically 30–50% below hospital rates for the same implant and surgeon. Medicare Advantage plans increasingly direct patients to designated bundled-payment facilities where your out-of-pocket liability is capped.

Why prices vary - and what it means for your coverage
Setting matters too: the median outpatient price is $2,380 versus $2,226 inpatient, so where a procedure happens often matters more than which hospital you pick. Setting drives most of the spread here: an ambulatory surgical center (ASC) is usually meaningfully cheaper than a hospital operating room for the same procedure, when your case qualifies.
On top of the facility price, your actual bill depends on your deductible, your out-of-pocket maximum, and whether every provider involved - not just the facility - is in-network.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$2,380 |
| Deductible met - 20% coinsurance | ~$476 |
| Out-of-network provider | $5,236+ |
