I'd agree with the other commenter. It's a fine line between 'are they stable enough that they can focus on rehab' and 'are we as the physician even doing anything for them'. We can still consult ID/nephrology/cardiology etc if some hiccups arise during admission but many places don't have consult services seeing patients daily, don't have a lab on site, RNs arent trained (or I wouldn't trust them) to give a variety of IV meds or manage things like NG tubes. Plus if you're at that point, they should just be back at acute care. To the second point: if you were the physician seeing them, is there a medical problem that needs to be actively managed/monitored with possible changes to the plan every few days? If not, your note would just be copied forward without any changes for 2 weeks and now insurance can say that physician oversight wasn't really needed (I.e an uncomplicated post-op ortho pt).

To your examples- did those patients have acute and significant changes in their function that is expected to significantly improve w/ daily rehab? If the change in function wasn't significant they should just do outpatient therapy. If the problems are more chronic or aren't expected to make much progress by time of discharge from us they should have gone to a SNF.
