A working reference for the dental CDT codes a billing team uses every week. Each code page covers what the code includes, how it's typically billed, the documentation payers expect, and the denial reasons it tends to draw.
The library is in progress. The first ten codes are the ones we see most across the practices and DSOs we work with.
CDT codes are maintained by the American Dental Association. These pages are editorial billing guides, not official ADA code descriptors.
