What 93248 covers
This service is the physician’s review of extended ambulatory electrocardiographic data and preparation of an interpretation and report. It is commonly used when symptoms such as intermittent palpitations, dizziness, or syncope need rhythm evaluation over more time than a short Holter recording provides. A cardiologist or other qualified physician interprets the recorded tracing and documents relevant rhythm findings and their clinical significance.
Select this duration-based service when the monitoring period is more than 7 days but less than 15 days. The record should support the monitoring period and the physician’s interpretation of the submitted ECG data. Under CMS, 93248 represents the professional interpretation and report only; the technical portion is covered by a separate code. When the service is divided by component, the recording and scanning analysis are represented separately from this professional service.
