What it holds
A sequence listing additional identifiers for the same patient, each with its own issuer.
In migrations and validation
The standard way to carry a patient's previous or site-specific MRNs alongside the new enterprise ID. Useful when a migration remaps IDs but clinicians still search by old numbers. The older single-value Other Patient IDs (0010,1000) is retired.
