What 93000 covers
This service is a resting 12-lead electrocardiogram. A medical assistant, nurse, or technician places the electrodes and records the tracing. A physician or other qualified practitioner evaluates the rhythm, rate, intervals, axis, and waveform changes and documents an interpretation. Common indications include chest pain, palpitations, syncope, and medication monitoring. Clinically indicated preoperative evaluation may also involve an ECG. The complete service is commonly reported in offices and clinics; when a hospital supplies the tracing, the physician commonly reports only the interpretation.
Report 93000 when the same billing entity furnishes both the tracing and its interpretation and report. Documentation should identify the indication, retain the tracing, and include the interpreter's signed findings. CMS treats 93000 as a global-test-only code: report 93005 for the tracing alone or 93010 for interpretation and report alone rather than appending modifier TC or 26 to 93000. When multiple eligible cardiovascular diagnostic tests are furnished to the same patient on the same day, CMS applies the cardiovascular diagnostic multiple procedure reduction to the technical component.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

93000 billing questions
When should 93005 or 93010 be reported instead of 93000?
Report 93005 when the billing entity furnishes only the tracing and 93010 when it furnishes only the interpretation and report, as a physician may do for a hospital ECG. Report 93000 when the same billing entity furnishes both components.
Can modifier 26 or TC be appended to 93000?
No. CMS designates 93000 as a global-test-only code; report the professional portion with 93010 or the technical portion with 93005.
Is an ECG separately billable with an office visit on the same day?
A medically indicated ECG may be reported alongside an office E/M visit. If the clinician separately reports the ECG interpretation, that interpretation cannot also be counted as an independent interpretation in the E/M data element.
What documentation supports 93000?
Document the clinical indication, retain the 12-lead tracing, and include a signed interpretation with pertinent findings. An automated computer reading without review and interpretation by a physician or other qualified practitioner does not support the interpretation portion.
Should 93000 be billed for a rhythm strip?
No. A rhythm ECG using one to three leads with a report is described by 93040, rather than the complete 12-lead ECG code.
Is ECG monitoring during an exercise stress test billed with 93000?
Generally no. ECG monitoring is part of the cardiovascular stress test described by 93015 or its component codes. A distinct resting ECG requires its own clinical indication.
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.
