Electrocardiogram complete
CPT 93000 covers a complete electrocardiogram (EKG or ECG), which is a test that records the electrical activity of your heart to detect rhythm problems, heart attacks, or other cardiac conditions. This includes performing the test, interpreting the results, and providing a written report.

Billing tips
Split bill 93000 into components (93005-TC and 93010-26) when technical and professional services occur in different settings
Impact: Prevents leaving $4-9 on the table when hospital performs tracing but your physician interprets; ensures both entities receive appropriate payment shares
Document medical necessity explicitly in the order and chart note, linking EKG to specific symptoms, diagnoses, or clinical indications
Impact: Reduces denial rate by 60-70% for medical necessity; each denial costs $13.91 plus $25-40 in appeal administrative costs
Always append modifier 25 to E/M service (not to 93000) when both are performed on same day with distinct documentation
Impact: Common error is placing modifier on wrong code; correct placement prevents E/M denial which typically represents $75-200 in additional revenue
Verify interpretation is signed and dated within facility policy timeframe, typically within 24 hours of tracing
Impact: Unsigned or delayed interpretations are vulnerable to RAC audits with 100% recoupment rate; affects entire claim value of $13.91
Do not bill 93000 during global surgical periods unless EKG addresses unrelated cardiac condition with appropriate modifier and diagnosis
Impact: EKGs for routine pre-op clearance within global period will deny; prevents $13.91 write-off and potential fraud flags
For Medicare Annual Wellness Visits, bill EKG only when medically indicated by symptoms or risk factors, not as routine screening
Impact: Medicare does not cover screening EKGs; medical necessity required to avoid 100% denial and potential beneficiary billing issues
