When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Both
  • Method: FISH

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • Staphylococcus aureus and Staphylococcus sp.coagulase negative rRNA [Identifier] by FISH in Positive blood culture
  • Staphylococcus aureus & Staphylococcus sp.coagulase negative rRNA
  • Staphylococcus aureus and/or coagulase-negative staphylococci (CoNS) commonly isolated from human blood cultures can be detected by qualitative, multicolor nucleic acid hybridization assays. This code is based on, but not limited in use to, the submitted test, AdvanDx's Staphylococcus QuickFISH assay, which is intended for use on cultured blood.
