New CDT Code

July 2013 Volume XLVIX Number 4

A new CDT code was established for 2013. It is D2929 prefabricated porcelain/ceramic  crown   primary  tooth.

 

The rationale for adding D2929 was that the prefabricated crown series (D2900D2999) in CDT 2011-2012 did not provide a code for a ceramic substrate material. However, with the increasing shift to esthetic materials, the demand for accurately reporting for an esthetic anterior and posterior crowns for the primary dentition was growing.

 

The prefabricated zirconium crown for primary teeth is individually milled to a generic tooth preparation model rather than to a finished tooth preparation. In many ways, it is similar to the prefabricated stainless steel crown (D2930, D2931), the prefabricated resin crown (D2932), and the prefabricated stainless steel crown with resin window (D2934) in all but material (and some details of tooth prep and design).
Since the material is porcelain/ceramic, some dental practices have reported this procedure as D2740. However, the D2700D2799 series is reserved for custom fabricated crowns, so a new code was needed specifically for a porcelain/ceramic prefabricated crown for a primary tooth.

 

Clinical Scenario for new Code D2929

 

A five-year-old patient presents with a large carious lesion approaching the pulp of tooth "S". The tooth has been uncomfortable for the past 24 hours. After a clinical and radiographic examination, the dentist makes a diagnosis of irreversible pulpitis, for which a therapeutic pulpotomy and full-coverage (crown) restoration is indicated. The parents are concerned with the esthetics of the restoration and request a "tooth-colored" material.
After consideration of the available esthetic alternatives for primary teeth, including a prefabricated stainless steel crown with a resin facing or window on the buccal aspect,  a prefabricated esthetic coated stainless steel crown, and a prefabricated resin crown, the dentist and parents select a prefabricated zirconium crown as the material of choice (new code D2929). Following completion of the therapeutic pulpotomy, the primary tooth is prepared for placement of a suitably sized prefabricated ceramic crown, cemented with a self-curing glass ionomer cement.
