Has anyone tried and succeeded at getting reimbursed by Medicaid for pre-approval expenses?

My mom has just been approved for 24/7 care by Medicaid starting May 1. We submitted the application on Feb 1. My lawyer gave me a phone number to call to ask if they will reimburse us for some of the homecare expenses we've paid out of pocket. She says she has no idea if they will, of course, but it's worth asking. I will call, but I was just wondering if anyone has tried and succeeded at getting reimbursed for pre-approval expenses.
