After you pay your deductible, you may still be responsible for some of the medical costs. Typically in the range of 10%-50% (so called Co-Insurance), until you reach the policy Limit (Maximum Out of Pocket).
Let’s say, for example, that a plan has a $10,000 Maximum out of Pocket, a deductible of $5,000, and Co-Insurance of 80%. This means that after your deductible, you still have to spend $5,000 out of pocket, equal to 20% of each bill, until the sum of your annual expenses for medical costs reaches $10,000. After this amount, the insurance company covers 100% of the treatment costs.
IMPORTANT: please remember that we are talking about using the services of a doctor, hospital, etc. within the network of a given plan!
