Why prices vary - and what it means for your coverage

A small number of hospitals (7) report prices above $4,183, including Corewell Health Ludington Hospital at $3,714, 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 $1,087 versus $217 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.

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.

Frequently asked questions: sinus surgery costs in Michigan

How much does a sinus surgery cost in Michigan?

Posted cash prices start at $279, with a median of $1,087; outlier facilities are left out. What you pay depends on the facility, your insurance, and whether you have met your deductible.

Freestanding ambulatory surgery centers are often cheaper still and may not appear in hospital price data - ask your doctor whether one is an option.

Why is a sinus surgery so much cheaper at some Michigan hospitals?

Typical prices vary about 7.3× (25th to 70th percentile of negotiated rates) because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Michigan, the median cash (self-pay) price is $1,343 versus a median negotiated rate of $288 - about 4.7× 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 sinus surgery in Michigan?

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.
