One thing I have learned is how important it is to be your own advocate, along with how little my local "experts" know. No dig on them, it's just that there is a reason why there are clinics that specialize in NTMs. The day my pulmonologist gave me the news that I tested positive to MABC, he gave me a prescription for 7% saline and told me I need to nebulize 2x/day. I later learned, that was really smart on his part. National Jewish NTM/BE Clinic stressed to me how important it is to nebulize with 7%. Studies have shown that nebulizing at early stages of the disease improves outcome. The lab should do a count and determine if your MAC is macrolide resistant, along with which other antibiotics would be classified as Resistant, Susceptible, or Intermediate. On September 13th NJH is having a NTM conference for all those diagnosed with an NTM. This is different than their professional NTM Conference. The registration fee is $25. It may be helpful for you. I have attached info of the conference.
