Medical providers often don’t bill the right insurance or even bill the insurance at all. In some cases they don’t bill for charges declined by insurance, or don’t bill for deductibles.
Here is a sample dispute of a Medical Bill
[Please be advise that I’m disputing (acct#) and requesting an immediate deletion of this account from all credit bureaus.Here is an alternative dispute if this is applicable to your situation:
Please not that I receive no bill for this account or My insurance was supposed to pay this account. Please provide evidence that the insurance company decline to pay.]
What you are doing is disputing the procedure because they will have to prove that the insurance decline to pay the claim.
