  • 93229 (Technical): Recording, connection, downloading, and software analysis of the device data.

Time Requirements

These codes are strictly for monitoring lasting between 12 and 48 hours. If the monitoring lasts less than 12 hours, you cannot bill 93228/93229. If it lasts longer than 48 hours (e.g., 7 days or 14 days), you must use the extended continuous recording codes (93241-93248).

Do not bill standard EKGs (93000) on the same day the Holter monitor is applied or removed unless there is a separate, emergent medical necessity.
