Positive and Negative Claim For Same Amount

Lemme preface with this is my first year with my own health insurance so bear with me.

I have Aetna insurance with a $1600 Deductible and a $3200 Out-of-Pocket Max. Before what I’m about to bring up, I already had about $500 towards my deductible for other health claims that I’ve already received bills for and have already paid off. But for the one I’m posting about:

I went to buy the medication PAXLOVID on July 8, 2024. I remember the pharmacist freaking out before I paid saying it’s gonna be a crazy high amount. She then said she found a manufacturer’s coupon and told me it would go from being about $1400 to $30. So I signed for it (didn’t charge any cards) and received the medication. I then get two claims on my Aetna account, one saying

“$1361.13 went toward your deductible $1390.44 went toward your out of pocket max”

And the other says “-$1361.13 went toward your deductible -$1390.44 went toward your out of pocket max”

I’ve tried calling multiple times for a clear explanation and I could just be dumb but I don’t quite understand what happened.

My deductible is currently maxed out at $1600 and my out of pocket max is at $1670.66. Does this mean I will have to pay that $1361.13 and if so, do I receive a bill for it at the end of the year? Should I have already paid for it? Do I not owe it because of the manufacturer’s coupon? Would greatly appreciate any advice or info about it since I’m new to it!

TLDR: got a positive and negative charge of the same amount, unsure if that means I’ll have to pay it/pretty much unsure of if deductibles are paid at the end of the year or I should’ve gotten a bill for it already
