Missing CDT codes


Cherry Hill, NJ
Best answers
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! :)
