Dаvid undergоes а dentаl surgery that requires IV sedatiоn. The оral surgeon wants to charge insurance $900 for IV sedation lasting 90 minutes long, which is the expected duration of the surgery.

David’s insurance company also requires a 10% coinsurance on the negotiated amount for IV sedation. How much will David have to pay out-of-pocket to meet the coinsurance requirement?
