The McKesson Z-Code Identifier is a unique 5-character alphanumeric code associated with a specific molecular diagnostics (MDx) test.

Z-Code Identifiers are assigned within the McKesson Diagnostics Exchange™ based on the uniqueness of each test or manufacturer's product being registered. For example, a test for the same analyte but performed by a different laboratory methodology is considered unique and is assigned a Z-Code Identifier.

Z-Code Identifiers are applied to all advanced diagnostic tests, including molecular diagnostic and genetic tests.
