The patient is undergoing a cardiac catheterization with a CRNA providing monitored anesthesia care (MAC). Code 00520 is for anesthesia for heart catheterization procedures. Modifier QX indicates CRNA service with medical direction by a physician, QS indicates MAC, and P5 indicates a patient with a severe systemic disease that is a constant threat to life. Thus, the correct code and modifier combination is 00520-QX-QS-P5.

Modifier 50 (Bilateral Procedure) is appended when a procedure is performed on both sides during the same session and the CPT® code is not inherently bilateral.

77066 is already defined as bilateral mammography

77065 is unilateral

75572 (CT heart) is not a bilateral procedure

73115 (MRI upper extremity joint) may be performed bilaterally and allows modifier 50

The scenario describes an emergency basic life support (BLS) ambulance service. The appropriate HCPCS Level II code for BLS emergency transport is A0429.

Modifier QN indicates that the service was provided by an ambulance supplier, and SH indicates the services were provided in an emergency situation.
