Really sorry to hear about your dad...I know exactly what your talking about w/ the insurance co. it can be so frustrating....it's so wrong when insurance co.'s tell doctors what tests to run, what med.'s to write how long we can stay in the hospitals etc. etc. ...I don't know if this link will offer anything for your situation but it never hurts to inquire...
