The example they gave is an employees husband had lung cancer. His first claim was something like $25000. The family plan puts $800 in your account. So it used all of the $800 and then he hit the deductible and the maximum out of pocket for the year. So once he hit the maximum he is covered at 100%. The second claim was $250000 ish. The family had a few other doctors visits the same year. So they had to pay their 20-30% for those visits since the $800 was already used. In the end, with the 20% coinsurance their out of pocket was around $7000 with the 30% plan it was around $7500.
For the family plan it is around $650 a year for the 30% plan and around $3250 for the 20% plan. So unless you think you will spend $3500 in medical expenses for the year the 30% plan might be a good fit for you.
As for the deductibles. There is a deductible for the employee and one for the family. I don't get why it is set up this way, but it is what it is I guess. Dental, vision, and prescription benefits stay the same. They didn't mention anything about accidental death & dismemberment. The meeting is strictly for medical insurance.
It isn't much different from what we have now. The only difference is instead of paying a copay you pay 20 or 30% of the bill. But the first $800 is paid by the money FedEx puts in the account for you.
