WHAT ARE DEX Z CODES?
The DEX Z-Code Identifier is a unique 5-character alpha-numeric code associated with a specific molecular diagnostics (MDx) test. Z-Code Identifiers are assigned within the DEX Diagnostics Exchange™ based on the uniqueness of each test or manufacturer’s product being registered.

WHERE DO I ACCESS THE Z CODES?
After registering through DEX, the Z codes can be found at the Mayo Clinic Laboratories site in the Customer Service menu (or go there via this link). This requires signing into the site. The user must then attest to being a registered user of the DEX Diagnostic Exchange by clicking the blue "Access DEX Z-Codes" button. An Excel spreadsheet will open to display the z codes.
