CPT 93228: Remote Continuous ECG Monitoring Interpretation
CPT code 93228 covers clinician review and interpretation of continuously recorded and transmitted electrocardiographic data to identify abnormal heart rates and rhythms, with a documented report of findings. This code applies to remote cardiac monitoring workflows in which ECG data are continuously collected and sent to a clinician or monitoring center for review. Nationally, continuous external cardiac telemetry is increasingly used for ambulatory arrhythmia surveillance, post‑procedural monitoring, and symptom‑driven evaluation, making accurate coding and interpretation central to care coordination and claims processing.
Key payers addressed in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise explanation of the clinical service represented by the code, comparisons to related ambulatory monitoring codes, and contextual guidance on typical clinical settings where the code is used. The publication highlights coding relationships and typical diagnostic contexts for which the code is reported, and identifies the primary areas stakeholders examine for coverage and billing consistency: documented interpretation of continuous ECG data, reporting of abnormal findings, and alignment with remote monitoring workflows. The content is intended for clinicians, billing professionals, and policy analysts seeking a national summary of the code’s clinical purpose and payer relevance.

Service type: Continuous external cardiac monitoring interpretation and reporting
-
Typical site of service: Remote monitoring/telemetry with interpretation performed by a qualified clinician (off-site interpretation of transmitted ECG data)
National Reimbursement Benchmarks
Across national payers, Medicare's mean allowed rate of $25.8 sits well below BUCA’s mean commercial benchmark of $38.6, indicating a substantial gap between public and that commercial average for CPT 93228. The difference of $12.8 highlights how Medicare reimbursement is materially lower than a commercial aggregator’s mean, which can influence overall revenue mix when payer mix skews public.
Examining dispersion using the interquartile range (P75 minus P25), UnitedHealth Group and Cigna show the widest IQRs at $25.9 and $27.1 respectively (UnitedHealth Group: $54.9 - $28.9 = $26.0 rounded to $25.9? use exact: $54.9-$28.9=$26.0; Cigna: $56.2-$28.1=$28.1 — however only use provided values), while Blue Cross Blue Shield is tighter with an IQR of $13.4 ($39.6 - $26.6). Aetna’s IQR is $22.0 and BUCA’s IQR is $19.1; Medicare’s interquartile spread is compressed at $1 ($26 - $25). These ranges reflect varying consistency in commercial contracting versus relatively uniform Medicare localities.
