Missing CDT codes

Hello all, hopefully someone out there can help me. If anyone has experience with CDT could you tell me where the missing codes are? I have Ingenix CDT 2012 and for some reason there is this HUGE gap of codes, from like D4xxx-D9xxx, and we cant figure out where the rest of the codes are. I know they're not in HCPCS anymore, and nothing in the CDT book says where they might be. I did some snooping around online and it says nothing was deleted for 2012, so I dont think that's it either. We review auto PIP claims here and we get a lot of Dental and OMS surgeons billing, so we kinda need to know what's up with those codes. If anyone can help I would be so grateful. Thanks! :)
