There are several issues with V6 I discussed with Jon at the AAP conference.
V5.1 is almost out and V5.2 is shortly after that. V5.2 is the one that is likely to get certified for meaningful use, BUT if he needs to get recertified because of a change in version, it MIGHT be V6, with PM becoming V6.?, thus avoiding the need for recertification when PM is added.
PM ability, clearing house availablility and patient eligibility will all be included in the "functional" V6
