Adding Missing Tests for an Electronically Interfaced Diagnostic Provider

When you order labs or imaging, or set up charge items, the search only shows tests from that diagnostic provider's test compendium (its catalog of orderable tests). There is no free-text option. If a test isn't showing up, it needs to be added to the compendium — and how you do that depends on how the provider is connected.

First, check the interface type

Go to Practice Settings > Diagnostic Providers. For each active provider, the Interface Type is shown as either Electronic or Fax.

For fax-interfaced providers, a practice admin can upload your own test list for the provider — see Uploading Your Own Test Compendium for a Fax Diagnostic Provider.

For electronically interfaced providers, the compendium comes directly from the lab's electronic interface, so it cannot be edited inside SigmaMD. To add or correct a test code:

1. Contact your account manager at the lab.
2. Ask them to submit an internal ticket with their EDI team (at Labcorp this is called an IT Central Service Request) to add or correct the test codes in the masterfile sent to our partner hub.
3. The EDI team coordinates with our partner hub to add or correct the test code on the interface.

This is all handled over email. Once the lab and our partner hub update the interface, the test code flows into your compendium automatically and becomes available in the ordering search.

When to expect the test in SigmaMD

SigmaMD refreshes compendiums every Wednesday. After the lab confirms a test code was added, allow up to a week for it to appear. If it's still missing after the next Wednesday refresh, contact our support team.

Tests that cannot be added

The lab's ticket will tell your account manager whether the test should be available. A test may not be added if it is no longer orderable, is an internal lab code, or is restricted. In that case, ask your account manager for the replacement test code.

A custom panel or test code stopped appearing

If a custom panel you have ordered before suddenly disappears from the search, the lab most likely deactivated it (for example, because one of its components was discontinued). Reactivating the panel in the lab's own system does not always send it back through the interface. Ask your account manager to submit the same EDI ticket so the panel is republished to the masterfile, then allow for the next Wednesday refresh.

If you have a lab panel in SigmaMD that includes the missing test, you may also need to update the panel once the code is available again. See Creating Lab Test Panels.
