Many of the time-based CPT codes have descriptions to the effect of "each additional 30 minutes", "each additional 15 minutes", etc.
Is there a general guideline which states what qualifies as the additional chunk of time? Let me explain...
Time: 1 hour, 2 minutes: do we get to count "an additional 30" beyond the first hour?
For critical care time reporting, it is nice that there is a matrix which specifies it in no uncertain terms.
But for other services, e.g., 92618 (CPT 2012), it is not clear to me.
Sometimes, some extra wording will make it clear; for instance, 94781 states "each additional full 30 minutes".
