Dental Benefit and Deductibles
With regards to deductible in your insurance plan you should know whether or not your insurance plan is based on a Calendar year or a Contact year.
Calendar year: is January through December, if your plan is based on a calendar year, you will pay your deductible once each calendar year.
Contract year: If your plan is based on a contract year (starts and ends during a different 12-month period), you will pay your deductible once each plan year.
It may take more than one dental care service or visit to satisfy your entire annual deductible, as some services might not count toward your annual deductible, such as diagnostic and preventive services, depending on the plan.
When your dentist submits a claim for a dental care service, your deductible is applied first, and then any coinsurance is calculated.
