CPT 93272: Ambulatory Event Recorder — Professional Interpretation
CPT code 93272 denotes the professional component for monitoring and interpreting patient-activated ambulatory event recorder transmissions over a period of up to 30 days. The code captures the clinician’s work in applying ECG leads, reviewing transmitted tracings associated with symptomatic episodes (for example, chest pain or palpitations), and advising the patient on next steps. This service is clinically important because it supports diagnosis of intermittent arrhythmias that may not be captured during brief in-office ECGs, enabling targeted treatment and risk stratification.
Key payers referenced include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what the code represents, the typical clinical workflow and sites of service, and the types of benchmarks and policy considerations commonly assessed for this service nationally. The publication highlights coverage and billing considerations, common modifier usage, and how professional-component coding differs from technical components for ambulatory monitoring devices. It also outlines where clinicians and billing staffs typically need clarity when documenting the review and interpretation of patient-transmitted ECG data. This overview is aimed at clinicians, compliance staff, and revenue cycle teams seeking a national perspective on coding and billing for ambulatory event recorder interpretation.

Billing Code Overview
CPT code 93272 describes the professional component of monitoring and interpreting electrocardiographic data from a patient-activated event recorder used during symptomatic episodes. The provider places ECG leads and equips the patient with an event recorder capable of recording and transmitting cardiac rhythm data for up to 30 days; the patient transmits tracings before and during symptoms such as chest pain, and the provider analyzes the transmitted recordings and advises the patient on appropriate action.
Service type: Cardiac ambulatory event monitoring — professional interpretation and management of patient-activated event recordings.
Typical site of service: Outpatient clinic or office setting, or other ambulatory environments where the provider can apply monitoring leads and instruct the patient on device use; device wear and symptom-based transmissions occur during the patient’s routine activities outside a facility.
