Insurance coverage for Omnipods by Horizon Blue Cross NJ?

We have Horizon in NJ, specifically NJ Direct 15. We only started the Omnipod in August, but were told we pay 10% of all costs, until we hit something like $500 out of pocket costs and then everything is covered 100%. I can’t say for sure that this is correct, as Horizon has a history of charging us for things long after the fact, even things they’ve told us are covered. Maybe I better go check for sure!
