Explanation
Updated October 26, 2026
Level 1 continuous ambulatory ECG (Holter-type) monitoring, professional component, for a recording of 60 hours to 13 days.
What it covers
G659 is the professional component of Level 1 continuous ECG monitoring (for example Holter) for 60 hours to 13 days (J16).
Level 1 needs a device that records three or more channels at once, captures every beat continuously with three or more skin electrodes, allows analysis and manual review of all parts of the recording, produces graphical and quantitative reports, and has a patient diary and event marker. Minimum 12 hours of monitoring (J16).
Billing rules
- Minimum 12 hours of monitoring; the device must meet the Level 1 definition (J16).
- Maximum one professional component, one technical recording component and one technical scanning component per patient, per recording (J16).
- For recordings over 36 hours, bill the code for that duration; don't bill multiples of shorter-duration codes (J17).
- External loop recorders that rely only on patient activation and can't analyze rhythm in real time are not insured (J17).
- The report must state the number of channels, whether the recording was continuous, whether analysis was real-time, post-hoc or both, and the device manufacturer and model (J17).
- You must personally interpret the results to bill the professional component (J1).
Often billed with
- G684 technical recording component for the same recording (J16).
- G685 technical scanning component for the same recording (J16).
