D2950 Buildup vs. D2949 Foundation

Many dentists routinely remove all existing filling from a tooth when they do a crown prep. This can leave irregularities, undercuts, divots. The dentist then places a material to fill in these irregularities, so the final shape of the prepared tooth is "ideal". This is often confused with a D2950 buildup, which is a similar procedure but is done for a very different reason.

A new CDT code (D2949) was implemented in 2014 to help eliminate some of this confusion, help providers properly code this service, and submit claims using the procedure codes that most accurately reflect what they performed.

D2950 - Core Buildup

D2949 - Restorative Foundation
