CPT Code 93000: Electrocardiogram (ECG/EKG)

What is CPT code 93000?

CPT code 93000 refers to a routine ECG (electrocardiogram) that includes both the technical and professional components—specifically, the rhythm ECG tracing and the interpretation and report. This current procedural terminology code is commonly used in clinical settings to evaluate cardiac function and detect abnormalities such as arrhythmias, acute myocardial infarction, and other heart conditions.

The procedure involves placing 10 electrodes to generate a 12-lead ECG, providing a multi-angle view of the heart's electrical activity. The EKG interpretation, conducted by a qualified provider, assesses rhythm, conduction, and signs of ischemia. This test is frequently ordered during routine physical examinations, preoperative assessments, or when patients report symptoms like chest pain, syncope, or palpitations.

CPT Code 93000 documentation requirements

To support medical necessity and ensure compliance with the Medicare Claims Processing Manual, healthcare professionals must include the following in the patient’s medical record:

• Confirmation that a 12-lead ECG was performed
• Clear indication for the ECG (e.g., chest pain, evaluation for arrhythmia)
• A written interpretation and report detailing rhythm and any abnormalities
• The signature of the interpreting provider, such as a physician or other healthcare professional

These elements help demonstrate medical need, especially when claims are reviewed under Local Coverage Determinations (LCDs).

CPT code 93000 billing guidelines

• 93000 includes both the ECG tracing and interpretation. It should not be billed separately from 93005 (technical component only) or 93010 (interpretation only).
• The test must be ordered by a qualified healthcare provider, and documentation must support the service's necessity.
• Medicare generally pays for CPT 93000 when the test is used to evaluate signs or symptoms rather than for preventive services.
• Reimbursement may vary depending on the setting (e.g., emergency department, outpatient clinic), and practices should follow revenue cycle management best practices to avoid denials.
• While ECGs can be performed during routine check-ups, the U.S. Preventive Services Task Force does not recommend them as a preventive screening tool in asymptomatic adults, which can affect coverage decisions.
• Only the professional component (93010) may be billed if the ECG was performed elsewhere.
• The American Medical Association maintains the official 93000 CPT code description, and any changes or updates should be referenced directly from AMA sources.
• Accurate EKG billing ensures appropriate payment and minimizes audit risks. Use clinical judgment and proper coding to ensure your claims are defensible.

Other relevant CPT codes

• 93005: ECG tracing only, without interpretation
• 93010: ECG interpretation and report only
• 93042: Rhythm ECG, one to three leads; interpretation and report only
• 93041: Rhythm ECG with one to three leads, but only the tracing is done, without interpretation or a report
