Medicaid
Medicaid is run by each state, and it pays fixed rates to the providers that accept it, so the price doesn't change from one hospital to the next. Most people on Medicaid owe nothing or a small copay for covered care, but what's covered and what you owe depends on your state and plan. CostKits doesn't show a Medicaid price here because those rates are set by the state, not negotiated by each hospital. The question that matters is whether the provider accepts your Medicaid plan, so ask before you schedule.

Quick take
- Jersey Community Hospital is the lowest-cost option at $1,907 - $1,851 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 $3,758, 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.
BJC HealthCare, SSM Health, Mercy Health, and CoxHealth divide Missouri roughly by region, with meaningful inter-system competition in both St. Louis and Kansas City. Barnes-Jewish Hospital (BJC) is the dominant academic medical center. Rural Missouri - particularly the Ozarks - has significant critical access hospital coverage where pricing structures differ from PPS hospitals. 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 (3) report prices above $5,750, including Mercy Hospital Jefferson at $14,602, 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 $3,758 versus $1,907 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.
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 | ~$3,758 |
| Deductible met - 20% coinsurance | ~$752 |
| Out-of-network provider | $8,268+ |
