Question 97607/97608 - Global or not Global

Best answers
The question is – with regard to 97607/97608 and global periods:

Do these codes fall under the global period when a post-op patient follows up with the same surgeon for the same surgical site (anatomical)? Note: These codes state no global period (xxx).

The concern is when a major surgery has a global but the subsequent therapy (prescribed within 90days) does not, my thinking is the 97607/8 would not fall under the global period but I'd like to confirm that this is correct. Please advise. Thank you.
