Quick take

  • Swedish Health Services is the lowest-cost option at $2,595 - $3,937 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 $6,532, and it's often lower than what insurance pays before your deductible is satisfied.
  • Ask whether this procedure can be done at a freestanding ambulatory surgical center - they're typically 30-60% cheaper than a hospital for identical care, and most aren't in this hospital-only dataset.

Providence Health, Swedish Health Services (a Providence affiliate), and UW Medicine compete in the Western Washington market. Kaiser Permanente Washington has substantial commercial market share in the Puget Sound area. Eastern Washington operates as a distinct, lower-cost market anchored by Providence and MultiCare. Washington state has active price transparency enforcement. Appendectomy is largely an emergency procedure, which eliminates most price shopping. The main cost driver is surgical approach and admission status: uncomplicated laparoscopic appendectomies are increasingly performed as same-day outpatient cases at substantially lower total cost than open or complicated inpatient stays. Your primary out-of-pocket exposure is driven by your deductible and whether the facility and surgeon are both in-network.

Why prices vary - and what it means for your coverage

A small number of hospitals (1) report prices above $12,302, including Alliance for South Sound Health at $16,687, 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 $6,532 versus $5,835 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.

None of the prices above are what you'll necessarily owe: your deductible, out-of-pocket maximum, and each provider's network status all still apply.

Your situation Estimated out-of-pocket
Deductible not yet met ~$6,532
Deductible met - 20% coinsurance ~$1,306
Out-of-network provider $14,370+
