oxygen therapy

Aloha!
We use oxygen in our walk-in clinic for a variety of reasons; driving a nebulizer, waiting for an ambulance, initial response to someone hypoxic, etc. I cannot find a CPT code for "Oxygen Therapy", or Oxygen Treatment, etc.

We are using 99605 (Medication Therapy Management Services...)

Any Suggestions?
Thanks

99605

The code 99605 is for "Medication therapy management service(s) provided by a pharmacist"
Try looking up information on Nebulizers: A7003-A7006 (set up), 94640 (treat for dx) , 94642 (treatment) , 94644 (prolonged past 1 hr) and 94664 (teaching). Hope this helps, It's what I have so far... Anyone else with advise?
