Don’t forget, insurance covers 50% before the deductible is met, not after. When a policy has that verbiage, usually there’s a footnote that states how those claims are handled in the future. From what I’ve seen, that could mean that insurance will cover 100% of said procedure after the deductible is met or it could mean a co-insurance of 30%.
After the deductible is met, OP won’t necessarily pay 50%. The percentage of the bill that OP and/or insurance will pay will be on a footnote at the bottom of the blue plan overview page (at least it’s blue when looking at plans from the ACA marketplace).
