Its not just the OOP. Its also the annual premium cost. You have to combine the two to get the actual annual cost.
Potential maximum annual cost, not actual. It's a disservice to your client to disregard their needs and usage and jump right to the worse case scenario.
Realistically, it's pretty rare to hit your MOOP. Here in my state, it's basically a wash at that point anyway. Argument's sake, Family rates on Oscar's Standard Platinum Premium+MOOP= $24,220, Bronze Premium+MOOP=$24,748. EmblemHealth's Platinum is $24,544, Bronze is $24,808.
Would you really advise your low-to-normal-usage clients to choose a plan that costs $600-700 more every month, just to save $300-600 over the year if they somehow are unlucky enough to hit MOOP?
In my "real usage scenarios", overwhelmingly, the silver/gold plans win out in terms of value. A normal person with normal usage will spend the least over the year on those tiers.
By the "potential annual cost" method, they're the worse value, with the highest Premium+MOOP costs. In real life, it's the opposite.
Heavy users benefit from Platinum, non users benefit from bronze/cat.
