Summary
Aetna's Clinical Policy Bulletin 0664 (reviewed 2026-10-07) classifies Signal-Averaged Electrocardiography (SAECG), artificial intelligence algorithmic electrocardiogram assessment, remote algorithmic analysis of electrocardiographic data, and vMap non-invasive arrhythmia analysis as experimental, investigational, or unproven. These procedures are not covered by Aetna. Billing teams must deny or refuse claims for CPT codes 93278, 0764T, 0765T, and 0897T when submitted for the listed indications.
Action Required
Billing team must verify current policy applicability with Aetna and implement the following controls: (1) Flag or deny claims submitted under CPT 93278 (Signal-averaged electrocardiography), 0764T (Assistive algorithmic electrocardiogram for cardiac dysfunction), 0765T (Assistive algorithmic electrocardiogram related to previously performed ECG), and 0897T (Noninvasive augmentative arrhythmia analysis) when billed for the indications listed in CPB 0664 (acute coronary syndrome screening, hypertension detection, heart failure evaluation, and arrhythmia planning); (2) Ensure that providers and front-desk staff understand these codes are non-covered under Aetna and counsel patients about potential out-of-pocket liability before service delivery; (3) Update billing system edits and prior authorization workflows to reflect non-coverage status. NOTE: No source-stated effective date is provided in this policy review. The 2026-10-07 review date is not an implementation deadline. Confirm with Aetna whether this policy was already in effect or is newly effective.
