Cardiac magnetic imaging differs from traditional magnetic resonance imaging (MRI) in its ability to provide a physiologic evaluation of cardiac function. Traditional MRI relies on static images to obtain clinical diagnoses based upon anatomic information. Improvement in spatial and temporal resolution has expanded the application from an anatomic test and includes physiologic evaluation of cardiac function.
Flow and velocity assessment for valves and intracardiac shunts is performed in addition to a function and morphologic evaluation. Use 75559 with 75565 to report flow with pharmacologic wall motion stress evaluation without contrast. Use 75563 with 75565 to report flow with pharmacologic perfusion stress with contrast.
Listed procedures may be performed independently or in the course of overall medical care. If the physician providing these services is also responsible for diagnostic workup and/ or follow-up care of the patient, see appropriate sections also. Only one procedure in the series 75557-75563 is appropriately reported per session. Cardiac MRI studies may be performed at rest and/or during pharmacologic stress.
Therefore, the appropriate stress testing code from the 93015-93018 series should be reported in addition to 75559 or 75563.
