Diagnostic tests such as FDG-PET distinguish between dysfunctional but viable myocardial tissue and scar tissue in order to affect the management decisions in members with ischemic cardiomyopathy and left ventricular dysfunction.Īetna considers PET for absolute quantitation of myocardial blood flow (AQMBF) experimental and investigational because the value of this test in guiding management has not been established.įDG-PET is considered medically necessary to identify and monitor response to therapy for established or strongly suspected cardiac sarcoid.Īetna considers FDG-PET medically necessary for the following oncologic indications, when the following general and disease-specific criteria for diagnosis, staging, restaging and/or monitoring are met, and the FDG-PET scan is necessary to guide management: The identification of members with partial loss of heart muscle movement or hibernating myocardium is important in selecting candidates with compromised ventricular function to determine appropriateness for re-vascularization. The greater specificity of PET makes a SPECT following an inconclusive PET not medically necessary. For use in assessment of coronary artery disease after cardiac transplant.įluorodeoxy-D-glucose (FDG)-PET scans are considered medically necessary for the determination of myocardial viability prior to re-vascularization, either as a primary or initial diagnostic study or following an inconclusive SPECT.The PET scan is used in place of, but not in addition to, a single photon emission computed tomography (SPECT), in persons who meet medical necessity criteria for a cardiac SPECT (see CPB 0376 Single Photon Emission Computed Tomography (SPECT)) or.PET scans using rubidium-82 (Rb-82) or N-13 ammonia done at rest or with pharmacological stress are considered medically necessary for non-invasive imaging of the perfusion of the heart for the diagnosis and management of members with known or suspected coronary artery disease, provided such scans meet either one of the two following criteria: Number: 0071 Table Of Contents Policy Applicable CPT / HCPCS / ICD-10 Codes Background ReferencesĪetna considers positron emission tomography (PET) medically necessary for the following cardiac indications:
