How often will Medicare pay for my mask supplies?

[mirkee]

I am using an F20 Airfit face mask (Resmed?).  I am coming off an N20 due to mouth breathing.  I used to get N20 cushions more often than the F20.  How often should I be getting free F20?  I have full Medicare with a PPO, BCBS supplemental.
