This is not my area of expertise, but everything I can find says that you should use G0403.
I looked up the CCI conflicts. There is a CCI conflict between G0402 and 93000. There is not a CCI conflict between G0402 and G0403.
Additionally, I've pasted some info below from the AAFP website:

IPPE Coding
The four HCPCS codes used to report IPPE services and ECG screenings are:
- G0402 – IPPE is a face to face visit. Service is limited to a new beneficiary during the first 12 months of Medicare enrollment.
- G0403 – Electrocardiogram (ECG) performed as a screening for the IPPE (with interpretation and report)
- G0404 – ECG performed as a screening for the IPPE (tracing only without interpretation and report)
- G0405 – ECG performed as a screening for the IPPE (interpretation and report only)
