Answer
Stephanie belongs to 60/40 co-insurance clause of the PPO
Step-by-step explanation
Cost sharing occurs when an individual and the health insurance company pay for the health care costs. Here, deductibles, coinsurance and copays all occur. A deductible amount is normally paid by a person before his health insurance starts to pay. In this case;
Bill incurred=$2000
Deductible=$1000
Remaining amount=$2000-$1000=$1000
40% ×1000=400 insurance paid
60% =600
