Question re OMRA

[Armds1]

I could use some advice...here is a scenario I've never come up against. I have a resident with an order for PT and OT. She is also going out of the facility monday to friday for radiation tx. She has been too weak and has been refusing rehab for the past two weeks.  The window for her 30 day PPS assessment is 10/27 to 11/04. She had no rehab 10/21, 10/22, 10/27-11/04. PT was d/c'd 11/6, OT d/c'd 11/7 due to her inability to participate. She is still skilled for unstable condition, lab work is way off, etc... My question is do I have to do a 30 day then do an OMRA? Resident technically had no rehab since 10/24 and will not score in a rehab RUG for the 30 day. Or ... can I combine the 30 day with the OMRA ? 
Thanks for any advice,
