Reader Question:
Choose Correctly Between Modifiers QY and QX

Question: I’m coding for a procedure that included an anesthesi­ologist and CRNA. Can you clarify for me how to bill with the QY modifier?

Answer: When an anesthesiologist and CRNA work together, you need to append the appropriate “performance” modifiers to indicate each provider’s role in the procedure.

The QY modifier (Medical direction of one certified registered nurse anesthetist (CRNA) by an anesthesiologist) shows that the anesthesiologist medically directed the CRNA during the case; you should only append it to the anesthesiologist’s claim. The corresponding modifier for the CRNA’s service when medically directed is modifier QX (CRNA service: with medical direction by a physician).

Several other modifiers are available to indicate medical direction or medical supervision, depending on the circumstances. They are:

  • AD (Medical supervision by a physician: more than four concurrent anesthesia procedures)
  • QZ (CRNA service: without medical direction by a physician)

QK (Medical direction of two, three, or four concurrent anesthesia procedures involving qualified individuals).
