Dental insurance companies will refer to the patient’s plan limitations and exclusions when considering the dental claim. If performing for replacement restoration, explain the reason of necessity which should indicate presence of decay.
If reporting for a buildup, do not report composite restorations, report D2950.
If reporting for closure of an endodontic access hole, indicate this on the claim form/narrative.
Submitting the claim with x-rays is not enough to facilitate coverage and payment in some cases. Therefore, it is recommended that you provide a narrative explaining the necessity and prognosis.
