Welcome to the CKD Quality Improvement Online Data Dictionary page.
Please, before you carry on, read the important note below:
The Data Dictionary presented on the next page, dynamically parses thousands of medical codes, their terms, domains and subdomains as well as study metadata, and presents them in a navigatable and searchable view inside your browser window. Because of the amount of data loaded, the process may take a while (20 seconds on Google Chrome, Firefox and Safari on average, but considerably more on Internet Explorer). We highly recommend that you use Google Chrome to access the next page, as it has been extensively tested. If you receive a 'Script' information message on Internet Explorer 8, please click 'No' at the prompt to continue loading the Data Dictionary.
Please note that the Online Data Dictionary page is incompatible with Internet Explorer 6, and considerably slow on Internet Explorer 7. If you use any of these versions, you are highly encouraged to update your system.
If your system and/or browser version is incompatible with our Online Data Dictionary, you can still download a Microsoft Excel version by clicking here. Just de-compress the file, which you can then open in Microsoft Excel or any other Spreadsheet viewer.
