BiPap eligibility

Post Covid my respiratory muscles have declined to MIP -37 LLN is 60. MEP is 80. Cpap isn’t working for me as I can’t exhale easily at pressure of 15. I have no neurological diagnosis and sleep test AHI was 3.6. Now, how can I get bipap to help with breathing? Pulmonary specialists don’t understand resp muscle weakness, neurologists don’t understand pulmonary weakness.

What CPAP machine are you using? It would help if we knew the exact make and model.

And does your current CPAP have a form of exhalation relief? If so, is it turned on and what setting are you using?

In the US, most insurance companies will insist that a doctor sign off on the idea that exhalation relief has been tried to alleviate the problem of "the patient can't exhale comfortably enough for quality sleep" before they're willing to pay for a bilevel machine. If you are willing to pay the $2000 or so out of pocket, all you need is a doctor who is willing to write the script the way you want it written.

So I would talk to the doctor who wrote your script for the current CPAP if possible. Explain that you are having enough problems exhaling comfortably that it is creating problems with getting quality sleep for you. And then ask if they're willing to write a script for you and the appropriate letter of medical necessity if you want insurance to pay for the machine.
