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

Setting matters too: the median outpatient price is $3,181 versus $1,197 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.
