When billing for Nebulizer tx's are you supposed to bill seperately for performing the beginning and ending O2 Sat's? Also when billing the A7003 Nebulizer Supplies, do you then bill seperately for the Inhalation Solution(s) used or are they considered in the supplies code? This may seem like a basic question, but there is much conversation going back and forth about it in our office today! Thank you!!!
