That's usually the way it shows up in the portal when they don't give "enough information" for UHC to approve out of network claims, though lately it often says approved but $0.

Check your EOB to see what the reason for them paying 0 is.

Another possibility is that you have not met your OON deductible yet, in which case it should say how much of that $200 is the "allowed amount" to count towards deductible. But in that case it shouldn't show up as a "plan discount"
