What 93247 covers
This service covers the technical review of ambulatory ECG data from a monitoring period longer than 7 days and up to 15 days. A monitoring company, cardiac diagnostic service, or other qualified technical staff scan the recorded tracings, analyze rhythm data, and prepare the technical report. Cardiologists and other clinicians may order this extended monitoring when intermittent symptoms, such as palpitations or episodic lightheadedness, are not captured during shorter monitoring.
Select 93247 for the scanning, analysis, and report portion of a service in this duration range; it does not represent the recording or physician interpretation. The record should support the monitoring interval and the technical analysis performed. A separate code covers physician review and interpretation. CMS identifies 93247 as technical-component-only, so it represents the technical service rather than a professional component split by modifier. The cardiovascular diagnostic multiple procedure reduction applies to its technical component when the reduction rule is triggered.
