About 93010: Routine 12-lead ECG interpretation and report only
Physician interpretation and written report of a routine 12-lead ECG when another entity furnishes the tracing, often in a hospital setting.
93010 covers a clinician’s interpretation of a resting ECG with at least 12 leads, including assessment of rate, rhythm, intervals, conduction, and possible ischemic changes. The interpreting clinician documents findings and a conclusion in a separate report. Cardiologists, emergency physicians, hospitalists, and internists may interpret tracings recorded in emergency departments, inpatient units, or preoperative areas. Most Medicare services for this code occur in facilities.
CMS treats 93010 as a professional-component-only code. The tracing-only portion is represented by 93005 when separately reported by the entity furnishing it. If one billing entity furnishes and reports both portions of the same ECG, use the complete-service code 93000 instead. Do not append modifier 26 to 93010; the code already identifies the interpretation and report. Support the claim with a separate, authenticated report containing findings and a conclusion, not just a note that the ECG was reviewed. Distinct, medically necessary ECGs repeated on the same date need separate interpretations; document their times or clinical indications. Modifier 76 may identify a repeat service by the same physician or other qualified health care professional.

Why are the office and facility amounts different?
For 93010 in Austin, the physician’s office rate is $8.46 and the facility-setting rate is $8.46: a difference of $0.00.
The calculation uses a different practice-expense RVU for each setting. Both amounts here are physician fee-schedule amounts. The facility figure does not include a hospital’s separate charges, so this comparison does not tell you the total cost of receiving care in each setting.

93010 billing questions
When should 93010 be reported instead of 93000?
Report 93010 when the billing clinician furnishes only the interpretation and report. Use 93000 when one billing entity furnishes and reports both the tracing and interpretation of the same routine ECG.
Does 93010 need modifier 26?
No. The code already represents the professional portion: interpretation and report.
Can an ED physician bill 93010 for reviewing an ECG during the visit?
Yes, if the physician provides a separate, authenticated interpretation with findings and a conclusion. A brief notation within the E/M documentation that the ECG was reviewed does not support a separate interpretation claim.
How are several ECGs on the same day reported?
A separate unit of 93010 may be reported for each distinct, medically necessary ECG that receives its own interpretation and report. Document the times or clinical indications; modifier 76 may be appropriate for a repeat service by the same physician or other qualified health care professional.
Does reporting 93010 affect E/M medical decision making credit?
A separately reported ECG interpretation cannot also count as an independent test interpretation in the E/M data element. An eligible order may still count under the applicable E/M data rules, but do not count the same work twice.
Is 93010 used for a rhythm strip interpretation?
No. For interpretation and report of a one-to-three-lead rhythm ECG, use 93042. Code 93010 is for interpretation and report of a routine ECG with at least 12 leads.
