## **What is the HCPCS code G0403?**
HCPCS code G0403 refers to a routine 12-lead electrocardiogram (ECG or EKG) performed specifically as a screening during the initial preventive physical examination (IPPE), also known as the welcome to Medicare visit, for new Medicare beneficiaries. This preventive physical examination IPPE is part of Medicare-covered services designed for disease prevention, health promotion, and screening for the initial Medicare enrollment period. G0403 includes both the ECG test and the interpretation and report of the results, qualifying as review and evaluation services under preventive services.
The purpose of this electrocardiogram routine ECG is to assess the electrical activity of the heart and detect potential heart conditions such as arrhythmias or ischemic heart disease early, before symptoms worsen. It is a physical examination with interpretation, performed as a screening to identify risk factors in a Medicare patient. The ECG is a non-invasive test where electrodes are placed on the patient's chest to record heartbeats and rhythm, generating an ECG with 12 leads.
This service is covered under Medicare coverage when performed as part of the initial preventive physical exam or initial Medicare preventive visit offered to patients within their first 12 months of Medicare enrollment. However, it is not included in the subsequent or ongoing Medicare Annual Wellness Visits. The code aids in billing for the routine ECG with 12 leads during this preventive visit and is distinct from related codes that cover only tracing or interpretation separately. The associated deductible and coinsurance apply with this code, as Medicare pays under specific guidelines.
## **HCPCS code G0403 documentation requirements**
The documentation requirements for HCPCS Code G0403 (routine 12-lead electrocardiogram ECG performed as a screening for the Initial Preventive Physical Examination - IPPE) include:
- Documentation must clearly support that the ECG was performed as a screening during the IPPE for a Medicare patient, specifically for a new Medicare beneficiary within their first 12 months of Medicare Part B enrollment.
- The medical record should contain evidence of the face-to-face welcome to Medicare visit where the ECG screening was ordered or conducted as part of evaluation services.
- The record must show the ECG procedure was performed with 12 leads, including the interpretation and report of the results.
- A diagnosis code consistent with the patient’s exam should be reported; however, Medicare does not require a specific IPPE diagnosis code for claims, so any diagnosis consistent with the exam is acceptable.
- Documentation should justify the test as a preventive screening, relevant medical and social history, not for diagnostic or treatment purposes, linked to the IPPE benefit.
- The service must be provided by a Medicare-recognized provider type such as a physician, nurse practitioner, certified clinical nurse specialist, or qualified non-physician practitioner.
- Accurate billing involves reporting G0403 for ECG with interpretation and report, distinct from codes for tracing only (G0404) or interpretation only (G0405).
- The associated deductible and coinsurance are applicable, so proper documentation for billing and payment is essential for ECG screening claims.
## **HCPCS code G0403 billing requirements**
The billing requirements for HCPCS Code G0403 (routine 12-lead electrocardiogram ECG with interpretation and report, performed as a screening during the Initial Preventive Physical Examination IPPE) include:
- The ECG must be performed as a screening as part of the IPPE for new Medicare beneficiaries within their first 12 months of Medicare enrollment.
- The billing provider must submit code G0403 specifically for the complete ECG screening, which includes tracing, interpretation, and report, distinguishing it from tracing-only (G0404) or interpretation-only (G0405) codes.
- A diagnosis code consistent with the preventive nature of the screening should be reported; however, Medicare does not require a specific diagnosis code for these claims as long as it is consistent with the exam.
- The service can only be billed once in the beneficiary’s lifetime.
- Billing must be done by a Medicare-recognized provider type, such as physicians, physician assistants, nurse practitioners, or clinical nurse specialists.
- If additional medically necessary ECGs are performed on the same day as the IPPE for the same patient, they should be billed with CPT codes in the 93000 series using modifier 59 for distinct services.
- Deductible and coinsurance apply to G0403.
- The IPPE itself is billed separately with code G0402 for the preventive physical exam.
## **Other relevant codes**
- **G0402** – Initial preventive physical examination (IPPE); face-to-face visit for new Medicare beneficiaries within their first 12 months of Medicare enrollment. This code is used to bill the IPPE visit itself, distinct from the ECG screening.
- **G0404** – Electrocardiogram, routine ECG with 12 leads; tracing only, without interpretation and report, performed as a screening during the IPPE. This code covers only the ECG tracing portion, separate from interpretation
- **G0405** – Electrocardiogram, routine ECG with 12 leads; interpretation and report only, performed as a screening during the IPPE. This code covers only the interpretation and report of the ECG tracing without the actual tracing procedure
