Yes means the benefit is covered 100% by your plan. No means it’s not. Percentages are the amount of the plan covers, not how much you owe.

Only Plans K and L have out-of-pocket limits. In these plans, once you hit the yearly limit, your gap plan picks up 100 percent of the covered services. In 2021, the limit for Plan K is $6,220, and the limit for Plan L is $3,110.
