Knee Replacement Cost in Maine (2026): Average Prices & What You'll Pay

What does a knee replacement cost in Maine?

A typical knee replacement in Maine costs $4,453–$11,323 for a commercially insured patient, including facility and physician fees. The median reported facility price across 25 hospitals is $2,226. This estimate is based on CMS fee schedules and hospital price transparency data published under federal law.

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.

Even within Maine, Portland ($2,121) and Belfast ($32,611) are 15.4× apart on the median price. Maine prices for a knee replacement span 152.1× across 25 reporting hospitals, from $506 (Sebasticook Valley Health in Pittsfield) up to $76,956 (Sebasticook Valley Health in Pittsfield) for identical care. The median Maine price is $2,226. Most facilities fall between $2,014 and $4,871. Insurers negotiate this down to a median of $1,004, while self-pay patients are quoted $2,226 — about 2.2× higher, so asking for the cash or insurer-negotiated rate is often the single biggest lever on your bill.

Most expensive knee replacement providers in Maine

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.

Why prices vary this much

A small number of hospitals (8) report very high prices above $12,052, which drives much of the overall price range. Excluding these, most facilities cluster in a significantly tighter band.

Setting drives much of the gap in Maine: the median outpatient price is $2,217 versus $2,222 inpatient, so where a procedure is performed often matters more than which hospital you choose. Of the Maine facilities reporting prices, 11 fall in a low-cost tier (up to $2,014) while 11 sit in a high-cost tier ($6,029 and up) — a lower-priced option almost always exists within the same state.

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.

Across 25 Maine hospitals that publish prices, a knee replacement ranges from $506 to $76,956, with a median of $2,226. Most facilities fall between $2,014 and $4,871. What you pay depends on the facility, your insurance, and whether you have met your deductible.

Based on declared prices, the lowest-cost facility in our Maine data is MaineHealth in Belfast at about $2,005. By metro, Portland has the lowest median ($2,121). Freestanding ambulatory surgery and imaging centers are often cheaper still and may not appear in hospital price data — ask your doctor whether one is an option.

Why is a knee replacement so much cheaper at some Maine hospitals?

Prices vary up to 152.1× because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Maine, the median cash (self-pay) price is $2,226 versus a median negotiated rate of $1,004 — about 2.2× higher. Asking for the cash price or your insurer's negotiated rate is often the single biggest lever on what you pay.

How much will I actually pay out of pocket for a knee replacement in Maine?

Your out-of-pocket cost depends on your deductible, coinsurance, out-of-pocket maximum, and whether the facility is in-network — not just the sticker price. If you have not met your deductible, you will typically pay the negotiated rate in full until you do. Use the CostKits cost forecaster to estimate your specific out-of-pocket amount before you go.
