Before you book: three questions that change the price
- Is this the self-pay price, and does it include the doctor, anesthesia and any lab or pathology? Those are often billed separately.
- Can you give me the price in writing, with the billing codes it covers?
- What happens to the price if something extra is needed during the procedure?

Quick take
- St Joseph Regional Medical Center is the lowest-cost option at $332 - $368 below the median posted price ($700), just by choosing where you go.
- Ask for the cash price if your deductible isn't met - the median cash price here is $700, and it's often lower than what insurance pays before your deductible is satisfied.
- Doctor offices and independent clinics may charge differently from hospitals for the same service and may not appear in this hospital-only dataset. Ask your doctor whether another site is an option.

St. Luke's Health System dominates the Boise metro and much of the state, with Saint Alphonsus (Trinity Health) as the primary competitor. Low facility density outside the Treasure Valley and Panhandle means limited price competition for most of the state's geography. Boise prices are generally moderate relative to national averages.

Why prices vary - and what it means for your coverage
Setting matters too: the median outpatient price is $700 versus $711 inpatient, so where a procedure happens often matters more than which hospital you pick.
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 | ~$700 |
| Deductible met - 20% coinsurance | ~$140 |
| Out-of-network provider | $1,540+ |
Frequently asked questions: chemotherapy infusion costs in Idaho
How much does a chemotherapy infusion cost in Idaho?
The typical insurer-negotiated rate is $132, with most facilities between $108 and $329 (based on 22 hospitals reporting negotiated rates). Posted cash prices at the middle 80% of Idaho hospitals run $116–$1,358; outlier facilities above and below that range are left out. What you pay depends on the facility, your insurance, and whether you have met your deductible.
Where is the cheapest place to get a chemotherapy infusion in Idaho?
Based on declared prices, the lowest posted price in our Idaho data is St Joseph Regional Medical Center in Lewiston at about $332. By metro, Idaho Falls has the lowest median ($700).
Why is a chemotherapy infusion so much cheaper at some Idaho hospitals?
Typical prices vary about 3× (25th to 70th percentile of negotiated rates) because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Idaho, the median cash (self-pay) price is $700 versus a median negotiated rate of $482 - about 1.5× higher. Asking for the cash price as well as 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 a chemotherapy infusion in Idaho?
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.
