I don't know if I agree with this one. Remember a new patient visit needs 3 out of 3 components to determine the level. You cannot double dip on the exam. Your preventive visit should be coded as a new preventive, but the office visit should be established. It is easier to carve out the established visit with 2 out of 3 components being the history and medical decision making.
Both visits should stand alone - without double dipping. Most payers too, will deny two New E/M's on the same day.
I didn't say you can NEVER bill 2 New E/M's on the same day. I'm only cautioning the double dipping on the exam component. Both visits should stand alone, if you are going to bill 2 new. Also, some payers not all, will deny one of them.
Just want to point out that no payer will reimburse for two new patient visits on the same date; so Efrohna is correct in the suggestion to code the new patient preventive medicine and the established problem oriented visit.
