I would advise my coders to assign D7300 because it is the corresponding code to the placement codes and was meant to remove a temporary device. In the CDT, it is found under the Oral Surgery section under Other Procedures. Implants placed for support of a prosthesis (D6010) have a different removal code (D6100) and these codes are found under Implant Services in the CDT. I can understand why this would pose a question as placing the TAD requires oral surgery to anchor the device to the bone.
