Effective 6/1/2021, UHC will require pathology providers currently submitting a DEX Z-Code for the Medicare MolDx program to also submit their registered Z-code on UHC Medicare Advantage claims. In the same format as Medicare, the Z-code will be submitted in Loop 2400. While UHC will not require a separate registration of these z-codes, providers will need to ensure qualifying tests are registered with the MolDx Program.
If a provider has not already registered their test for a DEX Z test code they can register at MolDX® Program (Administered by Palmetto GBA)
To access and obtain a DEX Z-Code identifier, visit the DEXTM Diagnostics Exchange, select "Register My Organization" and follow the prompts, including participation in the MolDX program.
XIFIN has confirmed this does not fall under the same initiative as the laboratory test registry, which has been delayed until January 1, 2022.
