Section 2 - Sharing

Sharing is a feature within DEX that allows the reference lab that is performing the test to share lab test information with the client lab—including DEX Z-Code™ identifiers and CPT® Codes, to be used for billing.

• If you will be billing this test to a payer, you will need to “Request Sharing” from your reference lab performing the test to view DEX Z-Code™ identifiers
• You do not need to enter and submit the test performed by your reference lab; you use the Z-Code obtained through Sharing

How to Make a Sharing Request:
After your organization is registered and your account is active:

1. Log in to your DEX™ Diagnostics Exchange Registry account
2. Select “Labs & Manufacturers” Catalog
3. Search for any of your reference labs
4. Click on that lab name link OR
5. Select the “+” sign to expand a parent organization’s individual facilities, find the facility you physically send the specimen for processing (or testing)
6. Select the “Request Sharing” button at the top right corner
7. Once your reference lab “approves” your sharing request, you can Search the Lab Tests Catalog by using the lab test code or name.
8. Click on the test to see the Z-Code to be added to your billing claim
