    What are the CPAP, BiPAP and Sleep Apnea related HCPCS, CPT or billing codes?

    E1399 is Miscellaneous and is used for other CPAP items.
    How often should I replace my mask?
    Medicare allows for mask cushion replacement every three (3) months, and a complete mask system replacement every six (6) months. CPAP manufacturers and vendors suggest these replacement schedules as well.

    In our experience, most mask cushions begin to deteriorate after about six months of use. The cushion eventually becomes too soft to hold a seal. The headgear straps lose elasticity and must be tightened more and more to get the same quality seal.

    We strongly suggest replacing cushions and pillows as soon as they start to soften. Air leaks may reduce the effectiveness of CPAP therapy and headgear that is too tight may cause facial sores at pressure points. In most cases, replacement headgear is available if it is stretched out or the Velcro worn out.

    To see what parts of your mask are replaceable refer to our Replacement Part Finder. Just search for your mask to see all of the replaceable parts.
    How do I care for my mask?
    Masks should be washed daily with warm water and gentle soap or baby shampoo. Let the mask air dry. Never use antibacterial soap as it will break down the silicone of the mask cushion. Avoid soaps that include lotion which can coat the mask and cause it to lose its seal. A safe cleaner is the Control III Disinfectant CPAP Cleaning Solution. Remember, going to bed with a clean face will improve your seal and protect the lifespan of your mask. Citrus Mask Wipes
    The best time to clean your mask is in the morning after use. This removes the oils left behind from your skin which can reduce the lifespan of your mask. We recommend using Mask Wipes to make daily morning cleaning easy. The mask wipes are made from materials that will not break down your mask.

    Why might I prefer a nasal mask?
    The ideal CPAP mask is not noticeable to the user during CPAP therapy. If you breathe through your nose only, the nasal mask may offer the best therapy. Nasal cushions create a very good seal around your nose, while keeping a small profile. Also, nasal masks can be found in silicone, gel, foam, or cloth material. The SleepWeaver masks are the only cloth masks on the market, and are a very popular choice among nasal mask users. Lastly, most nasal masks have a forehead support which offers stability and support for the mask.
