Dental insurance bundles service?

I had a Crown put in. The dentist billed the insurance two seperate procedures: a.Core Build-up b. Porcelain Crown. But the insurance says the core build-up is included in the bundled Crown price. So they only paid for the Crown. Question: Should the dentist bill me for the core build-up? Considering the insurance has paid for the bundled service, is that a double charge?
--------------------
Those are two seperate procedures, two seperate fees, and two seperate procedure codes, so you haven't been 'double-charged'. The insurance company probably doesn't cover core buildups, as some don't. I've never heard of a 'bundled crown price'... You could always as the dental office to resubmit the core fee, only this time send an xray and a narrative as to why the core was needed. If it gets denied again, you'll be responsible for the core fee. Good Luck! :)
