The DEX® Diagnostics Exchange is a molecular diagnostic (MDx) test identification and policy management solution that connects payers and labs to bring clarity to MDx testing. MDx tests are uniquely identified and cataloged using DEX Z-Code® Identifiers – Palmetto GBA’s unique and proprietary 5-character alpha-numeric codes assigned within the DEX® Diagnostics Exchange. The test registry catalog is available for reference and review by other stakeholders in the healthcare system.
