Save yourself MAJOR grief by not using LinCare. They will not return phone calls, can't explain their bills (I'm sure I have been overcharged), after more than 1 year of trying to get my needed supplies from Lincare, which were never mailed and that were authorized by my insurance co, my physician's office switched me to Sheldon Medical Supply Co. Linacre is truly the most frustrating and impossible company I have ever dealt with. I can't even give them a star!
