Paying a deductible before delivery??

Shay🎀

I’m 19w2d. And at my last appointment (Tuesday) I found out that I’d have to pay a deductible of 2,248.50 before February. I’m a tad bit upset I’m just now finding out this information. I called my insurance and they told me I only have to pay like 900 something dollars and they’ll cover the rest. I’m so confused. Any moms with experience in this are can you please shed some light on the situation.
