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

What does a appendectomy cost in Wyoming?

A typical appendectomy in Wyoming costs $3,278–$8,828 for a commercially insured patient, including facility and physician fees. The median reported facility price across 10 hospitals is $2,776. This estimate is based on CMS fee schedules and hospital price transparency data published under federal law.

Wyoming Medicine (based in Casper) and Banner Health serve much of the state's population, but Wyoming's frontier geography means the nearest hospital is often 50–100 miles away. Many Wyoming residents cross into Colorado or Utah for non-emergency specialty care. Critical access hospitals are widespread, and prices at rural Wyoming facilities often run high relative to the care complexity they handle.

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.

Location within the state matters too: Buffalo has the lowest metro median ($2,555) while Rock Spring runs highest ($13,312) — a 5.2× difference inside Wyoming alone. Wyoming prices for an appendectomy span 45.7× across 10 reporting hospitals, from $507 (Crook County Hospital in Sundance) up to $23,149 (North Big Horn Hospital) for identical care. The median Wyoming price is $2,776. Most facilities fall between $1,792 and $5,484. Insurers negotiate this down to a median of $798, while self-pay patients are quoted $3,621 — about 4.5× higher, so asking for the cash or insurer-negotiated rate is often the single biggest lever on your bill.

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 (3) report very high prices above $11,897, 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 Wyoming: the median outpatient price is $2,623 versus $3,322 inpatient — about 1.3× more, so where a procedure is performed often matters more than which hospital you choose. Of the Wyoming facilities reporting prices, 4 fall in a low-cost tier (up to $1,792) while 4 sit in a high-cost tier ($5,834 and up) — a lower-priced option almost always exists within the same state.

Among the cities with the most reporting hospitals, Gillette has a median reported price of $3,414 across 2 facilities, while facilities in Buffalo tend to report lower prices (median: $2,555). 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.

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 Wyoming?

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.
