New Jersey has a dense hospital landscape with RWJBarnabas Health, Atlantic Health System, Hackensack Meridian Health, and others competing for commercial contracts - but high labor costs, real estate, and regulatory burden keep prices elevated despite the competition. Northern New Jersey facilities are influenced by New York City-adjacent wage indices, which are among the highest in the country. 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

A small number of hospitals (5) report prices above $11,729, including CareWell Health Medical Center at $28,233, which drives most of the overall spread - excluding them, most facilities cluster in a much tighter band. Setting matters too: the median outpatient price is $5,273 versus $5,490 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.

Asking for the cash price or your insurer's negotiated rate is often the single biggest lever on what you pay.

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.
