CPT code 93224: Holter monitoring, up to 48 hours2026 Medicare rate & RVUs

Medicare pays $70.48 for 93224 nationally in the office. Local office rates run $61.98–$96.50.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
