If you've met the deductible for the plan year, the deductible is now off the table. And presumably you need to look at your policy to see what it covers after the deductible is met.
"50% before deductible" is an odd term that I haven't seen in an health insurance policy. Usually, coinsurance doesn't kick in until after the deductible is met.
I believe the German tanks are already traversing the steppes of Ukraine that they yearn for.
