# D2950 documentation requirements

Answer: Core buildup (D2950) is the classic bundled denial: payers fold it into the crown fee unless pre-operative evidence shows the tooth lost enough structure to need a separate buildup — and no major payer publishes standalone public D2950 criteria, so the bundling decision is adjudicated against the published crown rules (Delta Dental Ins.: a pre-operative periapical within one year of the prep plus photos and structural-loss qualification; Cigna: evidence of decay or fracture beyond a filling; DentaQuest Colorado: numeric surface-and-cusp destruction counts). Capture the pre-operative photo and radiograph before preparing the tooth — after the prep, a bundling denial is rarely winnable.
