Comp Update/CoPs

Does anybody know what the new regs require regarding the timing of the every 15 day Comp Updates related to reporting in IDG? i.e. the Comp Update must be completed no earlier or later than x amount of days before an IDG, or it must be completed within x amount of hours before IDG?

The reason I ask is this: Hypothetically, if an IDG meets on a Tuesday, for instance, then technically the week spans from Tues to Tues. If the office is normally closed on Sat and Sunday, then wouldn't all the patients need to be seen on Monday for Tuesday's meeting? I realize it can potentially be worked out so that about half of the patient load would only fall into any given week, unless, of course you had a change in level of care or some other non-routine event...

How do you do it where you work?
