Final answer:
The correct modifier for a CRNA's services when performed personally under an anesthesiologist's direction is QX. This ensures compliance with billing and is important for discussing the patient's care and recovery among the medical team.
Step-by-step explanation:
When a Certified Registered Nurse Anesthetist (CRNA) personally performs an anesthetic service under the medical direction of an anesthesiologist, the appropriate modifier to report for the CRNA's services is QX. This modifier indicates that a CRNA provided the service with an anesthesiologist directing the anesthesia care. It's vital that billing and coding professionals correctly use these modifiers to ensure accurate billing and compliance with insurance regulations. The process typically involves a collaborative discussion among the surgeon, nurse, and anesthesia professional to outline and review the key concerns for the patient's recovery and care to enhance patient safety and outcomes.
