Two separate amounts you might pay

1. Your co-pay — a percentage of the eligible cost, set by your income tier (0%, 40%, or 60%).

2. The "above-grid" difference — if your dentist charges more than the CDCP established fee, that gap isn't covered, regardless of your tier.

Example

Say a covered service has a CDCP established fee of $100 and you're in the 100% tier. The CDCP pays $100. But if your dentist charges $130, you owe the $30 difference. In the 60%-covered tier, the CDCP pays $60, you pay $40 co-pay, plus any above-grid difference.

This is exactly why asking "do you bill at the CDCP rate?" matters so much.
