I was finding it impossible to find it at chain pharmacies but i found a hospital pharmacy that carries it. (Not covered for home use - though covered for in hospital use). And I hope you don’t mind I’d like to piggyback on Zscline’s question and find out if anyone has had any luck taking a year’s worth of receipts for this out-of-pocket prescription expense and submitting it to traditional Medicare part B under their durable equipment and supplies category for reimbursement?
