How is the family deductible met in the Basic PPO?

The Basic PPO deductible for Employee + One or More coverage is $2,500 in-network and $5,000 out-of-network. All eligible in-network and out-of-network expenses from covered family members apply toward the deductible. Each family member has his or her own individual deductible and a family deductible, and coinsurance begins when either of those have been met.
