How do premium, copay, coinsurance, deductible, and out-of-pocket maximum all work together in the world of health insurance?

You pay any remaining deductible plus the coinsurance payment percentage. For example, let's say your coinsurance is 20 percent, meaning you're responsible for paying 20 percent of any doctor's bill. ... Once your out-of-pocket maximum has been met the plan pays 100 percent for covered in-network services

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."

hope this : )
