Erratum Description

Corrected Text


The editorial changes to D4230 & D4231 nomenclatures noted on page 107 (CDT Code Changes) are not shown correctly on page 34. The errors are:

  • Omission of the revision symbols before the nomenclatures
  • The location of the word “tooth” in both nomenclatures

▲ D4230 – anatomical crown exposure – four or more contiguous teeth or tooth bounded spaces per quadrant

▲ D4231 – anatomical crown exposure – one to three teeth or tooth bounded spaces per quadrant
