There are two types of nasal interfaces that are used with a continuous positive airway pressure (CPAP) device or a respiratory assist device (RAD) – a nasal mask and cannula-type interface. Both of these are coded A7034 and the code includes the soft interface. Codes A7032 and A7033 describe replacement soft interfaces. Code A7032 is used for a nasal mask interface that goes around the nose, but not into the nostrils. The description for unit of service for this code is "each".

Code A7033 is used for a nasal cannula-type interface. This interface extends a short distance into the nostrils. The description for unit of service for this code is "pair". For some products, there are two physically separate cushions or "pillows" – one for each nostril. Two cushions/ pillows equal one unit of service of A7033. For other products, the interface is a single piece with two protrusions that extend into the nostrils. One of these interfaces equals one unit of service of A7033.

Questions concerning the coding of specific items should be directed to the SADMERC.
