CDT Code Action Request Form – ( “Preface” includes Submission and Evaluation Guidelines and Completion Instructions)
There is one form used to request any type of CDT Code action— e.g., add a new procedure code; revise a current procedure code nomenclature or descriptor. A request may be submitted at any time, and must be on the current version of the form posted on this web page. The Microsoft Word® form intended to be downloaded to your computer, completed at your convenience and returned by email to email@example.com.
A separate request form must be prepared and submitted for each desired CDT Code action. One fully completed Copyright Assignment Agreement must be included when submitting one or more action request forms. Requests that are not accompanied by the completed Copyright Assignment will not be addressed by the Code Maintenance Committee.
Copyright Assignment Agreement Form
Each person or entity submitting a CDT Code Action Request(s) must include properly completed Copyright Assignment Agreement. One signed agreement form will apply to all submissions from the person or entity received during a maintenance cycle.
Action requests that are not accompanied by a properly completed copyright assignment form will not be addressed by the Code Maintenance Committee.
