This is a flat dollar amount that needs to be met before your health insurance will begin to pay.  For example, if your health insurance plan has a $1000 deductible, you will be required to pay the first $1000 upfront.  After the deductible has been met, the health insurance company will begin to pay it’s share.

Not every service has a deductible and some services may be included with coverage at no cost to you.
