Which modifiers report CRNA services when an anesthesiologist is supervising multiple cases?

The option that reports CRNA services when an anesthesiologist is supervising multiple cases is the combination of AD and QX modifiers.

The QX modifier indicates that the CRNA is being supervised by an anesthesiologist, which is essential when there are multiple cases being managed simultaneously. This modifier helps to clarify the role of the CRNA in the context of anesthesia services and highlights the relationship with the supervising anesthesiologist.

The AD modifier further specifies that the anesthesiologist is directing more than one anesthetic procedure simultaneously, a common scenario in busy surgical environments. By using these modifiers together, the billing accurately reflects the clinical situation, allowing appropriate reimbursement for the services provided under supervision.

In contrast, the other options include modifiers that do not pertain to the reporting of CRNA services under supervision. P1 and P2 modifiers are related to the physical status of the patient and not relevant to the supervision by an anesthesiologist. The QZ modifier alone indicates CRNA services without supervision, while the G9 modifier references a medical direction under specific guidelines but does not specifically denote the supervision of multiple cases by an anesthesiologist. Thus, option A is the most accurate choice for reporting CRNA services in this
