Quick take
- John H. Stroger, Jr. Hospital is the lowest-cost option at $1,197 - $1,984 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 $3,181, and it's often lower than what insurance pays before your deductible is satisfied.
- Ask the hospital whether your procedure will be billed as outpatient or inpatient - the two are priced differently, so confirm with your insurer first if it is planned.
Illinois presents two distinct markets: Chicago (highly competitive, high commercial rates, major academic medical centers) and downstate (lower density, smaller regional systems, lower rates). Northwestern Medicine, Advocate Aurora Health, and Rush University Medical Center compete aggressively in the Chicago market. Downstate Illinois prices typically run 20–35% below Chicago-area rates for identical services. 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 (6) report prices above $12,462, including Northwestern Medicine Delnor Hospital at $34,314, 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 $3,181 versus $2,880 inpatient, so where a procedure happens often matters more than which hospital you pick. Setting drives much of the spread here: whether the hospital bills the stay as outpatient or inpatient changes the facility fee, which is why two similar hospitals can bill very differently for the same procedure.
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.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$3,181 |
| Deductible met - 20% coinsurance | ~$636 |
| Out-of-network provider | $6,998+ |
