@johnhans my prescription was also expired in July. I sent my sleep medicine doctor a message on the Mayo Patient portal and asked him if they could renew it. I told him all was going well with the CPAP and I wasn't having any issues sleeping. He replied that he would renew it for a year and then setup another appointment at that time to see how it was going.

I would ask him that since he is not able to see you sooner than the middle of September why can't he renew the prescription so you can get replacement mask (your previous one that he more than likely allowed) until you are able to get the appointment? I would think they would want to help you with any CPAP issue.

I thought I would update you all on what happened. I finally got into my sleep medicine doctor and he said that the medical supplies company which is associated with my doctor's company told me wrong. My prescription had not expired and was good until November. He showed me on the computer my records. I thus saw my doctor months early. The medical supplies also told me that my CPAP machine was broadcasting my results so I did not need to bring it in. The doctor did not have any records so now I would need to make another appointment to see how I have been doing these last months. The problems of life. I did get another of my old mask and seem to be doing better with it.
