Appendectomy Cost in Washington (2026): Average Prices & What You'll Pay

What does a appendectomy cost in Washington?

A typical appendectomy in Washington costs $2,610–$9,684 for a commercially insured patient, including facility and physician fees. The median reported facility price across 41 hospitals is $3,158. This estimate is based on CMS fee schedules and hospital price transparency data published under federal law.

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.

The same appendectomy that costs $245 at Mid-Valley Hospital in Omak reaches $38,544 at PeaceHealth St Joseph Medical Center in Bellingham — a 157.3× gap across the 41 Washington hospitals reporting prices. The median Washington price is $3,158. Most facilities fall between $1,256 and $6,340. Insurers negotiate this down to a median of $3,484, while self-pay patients are quoted $3,332. Location within the state matters too: Omak has the lowest metro median ($1,203) while Vancouver runs highest ($5,876) — a 4.9× difference inside Washington alone.

Most expensive appendectomy providers in Washington

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 (1) report very high prices above $14,421, 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 Washington: the median outpatient price is $3,158 versus $1,380 inpatient, so where a procedure is performed often matters more than which hospital you choose. Of the Washington facilities reporting prices, 12 fall in a low-cost tier (up to $1,256) while 12 sit in a high-cost tier ($6,522 and up) — a lower-priced option almost always exists within the same state.

Among the cities with the most reporting hospitals, Vancouver has a median reported price of $5,876 across 3 facilities, while facilities in Omak tend to report lower prices (median: $1,203). City-level variation within a state often reflects local market structure, not procedure complexity.

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.

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 an appendectomy so much cheaper at some Washington hospitals?

Prices vary up to 157.3× because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Washington, the median cash (self-pay) price is $3,332 versus a median negotiated rate of $3,484 — about 1× 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 an appendectomy in Washington?

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.
