Why prices vary - and what it means for your coverage

A small number of hospitals (11) report prices above $3,348, including HCA HEALTHONE SPALDING REHABILITATION at $4,264, 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 $1,147 versus $789 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.

What you pay out of pocket on top of this depends on your deductible, your plan's out-of-pocket maximum, and whether every provider involved is in-network - not just the facility.

Typical prices vary about 3.6× (25th to 70th percentile of negotiated rates) because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Colorado, the median cash (self-pay) price is $1,147 versus a median negotiated rate of $595 - about 1.9× 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 Colorado?

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.
