Dentovio public answer
core buildup narrative
Sourced answer
A core buildup narrative should identify the tooth, state the decay or fracture that removed the tooth structure, state how much structure is gone and how much sound dentin remains after preparation, state that the buildup was necessary to retain the final restoration, and name the pre-operative and post-operative images on file. Cigna's REST-06 allows D2950 when decay or fracture makes the buildup necessary to retain the final restoration and disallows it on the same tooth and date as delivery of the final restoration, except that same-day CAD-CAM restorations may be considered, and disallows it alongside a post-and-core. Guardian ties the benefit to a covered crown or bridge unit with less than 3 mm of sound dentin remaining circumferentially after preparation. Delta Dental Ins. asks for a periapical radiograph, photographs taken within one year, and a narrative, and states that D2950 is not for material used to fill or smooth preparation geometry. Aetna asks for imagery from both before and after the buildup.

Dentovio is an independent publisher — not a dental payer, the ADA, X12, or any government agency. This page was drafted with AI assistance and verified against the primary sources linked here. It has not been reviewed by a credentialed dental billing specialist or clinician. The templates and the builder assemble sentences from entries you make; they do not generate clinical content, and they state only what you record. The payer criteria shown are those payers' published documentation rules as read on the last-verified date; individual plan contracts still control coverage, frequencies, and exclusions, and payers revise policy documents on their own schedules. Educational billing reference only, not billing, legal, or clinical advice. CDT codes are referenced by number only; CDT codes and descriptors are the property of the American Dental Association. This page provides educational billing guidance only and does not reproduce ADA copyrighted descriptors.
