What 93224 covers
A portable monitor records the patient's heart rhythm continuously for up to 48 hours while the patient goes about usual activities. The service is commonly ordered for intermittent palpitations, dizziness, or syncope when a brief office ECG may not capture the suspected rhythm abnormality. A technician handles the recording and analysis, and a qualified physician reviews the tracing and reports the findings. The test is commonly arranged through a cardiology practice or an outpatient diagnostic service.
Report 93224 when the complete service is furnished: recording, scanning analysis, and physician review and interpretation. If those parts are furnished and billed separately, codes 93225, 93226, and 93227 describe the recording, analysis, and physician interpretation, respectively. Documentation should support the monitoring period, the completed analysis, and the physician's interpretation. CMS applies the cardiovascular diagnostic multiple procedure reduction to the technical component when multiple applicable tests are billed; the reduction affects the technical portion, not the professional interpretation.

- 93241Ambulatory ECG
- 93241 is the complete continuous ECG service for monitoring beyond 48 hours and up to 7 days. Use 93224 for monitoring up to 48 hours.

93224 billing questions
When should 93224 be used instead of 93225, 93226, or 93227?
Use 93224 when the complete study is furnished and billed together. Use 93225, 93226, and 93227 when the recording, analysis, and physician interpretation are billed as separate services.
Can 93224 be billed with its component codes for the same study?
Do not report 93224 together with 93225, 93226, or 93227 for the same work; those codes describe the portions separately when the service is split.
What documentation supports 93224?
Keep the monitoring dates or duration, evidence that recording and scanning analysis were completed, and the physician's interpretation and report.
How does the multiple procedure reduction affect 93224?
CMS applies the cardiovascular diagnostic multiple procedure reduction to the technical component when multiple applicable tests are billed. The professional interpretation is not the component affected by this reduction.
When is a longer-duration ECG code more appropriate?
For continuous monitoring beyond 48 hours and up to 7 days, consider the longer-duration code family, including 93241 for the complete service.
