The “client mnemonic” is a generic term for a physician office. This may be a single physician, a group of physicians, or a group of physicians and other medical providers. You can think of each client mnemonic (“Clmne”) group as a copy of the office’s PMIS or EMR database. If one office changes a patient address, it is not changed in the other office, which is a typical HIPAA compliance need.

Accessions can be filtered by an ordering or copy-to physician, but every user has access to a common patient record. This mimics a hospital data layout. If one user changes a patient address, it is changed for all users. PMIS interfaces are not allowed in this model.
