I have a diagnosed frequent urination problem for which I have been able to get the catheter type devices with leg bag. Actually they work pretty well especially for long stretches where changing a diaper is a problem. Thing is I am now preferring diapers and am wondering if Medicare covers the cost of this (or part B supplement)? Anyone have any experience with this? Are you able to get diapers with a prescription? IF so do you have a choice of diaper and what distributors honor prescriptions?
