CPT 93005: ECG Recording Only, 12-Lead or More
CPT code 93005 describes the technical act of recording a 12-lead (or greater) electrocardiogram (ECG) without interpretation or reporting. Nationally, this code is used to capture the equipment, electrode placement, and signal acquisition portion of ECG testing when the interpreting clinician bills separately. Accurate use of 93005 matters for separating technical and professional components of cardiac diagnostics, for facility and professional billing alignment, and for claims processing consistency across payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find context on the clinical role of the recording-only ECG, common clinical scenarios that generate use of the code, and how the code relates to interpretation/reporting codes for continuity of care. The publication provides benchmarks and policy context relevant to coding splits between technical and professional services, typical sites of service where the recording is performed, and considerations for billing workflows when interpretation is performed by another provider.
The summary synthesizes operational implications for practices and facilities that routinely perform ECG recordings, clarifies relationships with related ECG interpretation codes, and highlights the national relevance of standardized reporting when the technical component is billed separately.

Typical Site of Service: Outpatient clinic, physician office, hospital outpatient department, or other settings where ECG recordings are performed
National Reimbursement Benchmarks
Medicare's mean rate of $7.3 sits well below BUCA’s average commercial mean of $42.7, illustrating a substantial gap between government and commercial reimbursement for CPT 93005. The difference of $35.4 underscores that commercial contracts with BUCA pay, on average, nearly six times Medicare for this service, which can materially affect payer mix revenue composition.
Examining dispersion using the interquartile range (P75–P25) highlights variation across payers: Blue Cross Blue Shield shows the widest IQR at $19.5 ($74.6–$54.6), while Aetna and UnitedHealth Group are tighter with IQRs of $7.0 ($13.0–$6.0) and $8.1 ($17.5–$9.4) respectively. Cigna’s IQR is $9.9 ($16.3–$6.4) and BUCA’s IQR is $10.0 ($49.3–$34.3); Medicare’s IQR is $1.0 ($8–$7), indicating relatively consistent Medicare locality rates.
