Prialt - Pharmacies Won't Accept Medicare-Approved Amount

I have a Med Supp client who needs to be treated with Prialt (the only non-narcotic intrathecal therapy approved for severe chronic pain). It's administered by a specially designed pump (a procedure called intrathecal infusion).

It falls under Part B (administered off-site by her doctor) and was authorized by both Medicare and her Supp carrier but the problem they are encountering is finding a pharmacy that will accept the Medicare-approved payment.

Has anyone run into this or have any suggestions?

Thanks.
