What 93227 covers
A physician reviews and interprets ambulatory electrocardiographic data collected during a short-term Holter recording, then documents the findings in a report. The test may be ordered for symptoms such as palpitations, dizziness, or suspected intermittent arrhythmia when a continuous ECG recording can help assess cardiac rhythm over the monitoring period. Cardiologists and other qualified practitioners who interpret ECG studies typically perform this professional service.
Report 93227 for the interpretation and report portion of the under-48-hour study, not for the recording or computerized scanning and analysis work. The record should support the monitoring period, the physician’s review of the tracing, relevant rhythm findings, and the resulting interpretation. CMS identifies 93227 as a professional-component-only code; the technical work is represented separately, including recording with 93225 and scanning analysis with 93226. Code 93224 represents the complete service when its components are reported together.

93227 billing questions
How does 93227 differ from 93224?
93227 covers only the physician’s interpretation and report. 93224 represents the complete under-48-hour service, including the technical work.
Should modifier 26 be appended to 93227?
No. 93227 is already designated as a professional-component-only code for interpretation and reporting.
Which codes represent the technical work?
93225 represents recording, and 93226 represents scanning analysis. These technical services are distinct from the interpretation reported with 93227.
When is 93244 a better fit?
Use 93244 for the interpretation and report of an extended ECG recording lasting more than 48 hours and up to seven days. 93227 is for the shorter monitoring service.
Is 93227 appropriate for a 30-day event monitor?
No. A 30-day event-monitor service uses a different code family, including 93272 for review and interpretation, rather than the short-term Holter interpretation code.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
