Explore the CPT codes that need DEX Z-Codes

We’ve previously announced that we’ll require DEX Z-Codes for certain molecular diagnostic test services on facility and professional clams. As of April 1, we’ll update the codes that will require a DEX Z-Code on a quarterly basis. You’ll need to check for the new codesopen_in_new before the beginning of each quarter.

This change is part of our UnitedHealthcare commercial plan Molecular Pathology Reimbursement Policy, Professional and Facilityopen_in_new and UnitedHealthcare Community Plan Molecular Pathology Policy, Professional and Facility Reimbursement Policyopen_in_new.

What this means for you

Using the DEX Z-Code with the appropriate CPT® code on a claim will clearly identify the test being performed. We urge laboratories that haven’t registered with the Palmetto GBA DEX Diagnostics Exchange to register today by visiting dexzcodes.comopen_in_new.
