After 90-day Compliance Period is done?

Does Medicare require any future follow-ups after the 90 day checkup for compliance?

I just remembered I have a 6 month appt with my sleep center coming up. If I am getting good results, and have no problems, would it be ok to just cancel? Is there any further need to ever go back, to get Medicare coverage on future supplies and eventually a new machine in 5 years?

Once a year your doctor needs to verify that you are using your CPAP and that it's benefitting you. Does not have to be a sleep doctor. For the past 10 years, my Primary care doctor verifies it at my annual physical. Of course, if you are having problems sleeping with your unit, you should see the doctor that prescribed it.

I have not had any health insurance for about 4 years now before that I did. In my life I have had 4 sleep studies done over the last 20 years. The first one said no sleep apnea even though my Husband has nudged me many times because I was not breathing. Second one I got a damn machine and the frustration of use is real, I gave up until Hubby insisted I use it. Third study said I didn't have sleep apnea, so I asked for the my entire record including all notes in my file for the date of my study. The tech stated I was laying on my left side most of the night. That was a lie and I know as did my my Hubby. I have arthritis in my left hip and at that time was not using anything to treat the arthritis and laying on my left side was not even possible. Now that I am taking medication for the arthritis, I can only lay on that side a few minutes. I fought the hospital on paying that bill with the help of BCBS of IL. I paid for the machine I am currently using as no insurance at the time. Where you got your machine from can access your machine. I found this out when my ramp settings were getting changed. I told them I can manage my own settings I don't need them to do it for me and if they did it again I would file a police report for attempted murder! LOL they have left the machine alone, the lady was shocked I knew how to get into my machine. I told her a simple internet search will teach you. I move every few years so doctors change as well, it surprises me how many doctors have no clue about sleep apnea. One doc's wife had it and he had no clue even how to write the prescription for the supplies. With sleep apnea one has to take charge of their own sleep.
