So after taking an at home sleep test I was was diagnosed with obstuctive sleep apnea and prescribed a CPAP machine (E0601 if that’s relevant at all.) However, after talking with my insurance provider I found out I’d basically pay for the whole thing by the time they would cover any of it, which I cant afford. At the same time my buddy got a BIPAP and only used it for a week before he stopped (something to do with heartburn/ unclear) and said hed sell me his for cheap. Would this be an ok alternative opposed to just not buying a CPAP altogether? Any danger in using a BIPAP instead of CPAP?
