Physical Therapy- billing eval/re-eval on same day as other procedures?

Best answers
I've been having a really hard time getting my physical therapy evaluations paid when any other form of therapy was provided during the same session, and I'm hoping someone can help.
97162 and 97530-59 : only 97530 was paid (Alaska Medicaid). 97162 denied for bundling.
97164, 97140 and 97110 : only 97140 and 97110 were paid (Premera BCBS), eval denied for bundling.

Is it inappropriate to bill for therapeutic codes on same day as eval? The code descriptions seem to allow it, and I can't find coding conventions preventing it, but I just can't get paid.
Any help you can give would be appreciated.
