Respiratory Question for the Week of June 5, 2017

Posted on Posted in Question of the Week, Respiratory


An outpatient lung cancer patient on a ventilator is receiving intermittent breathing nebulizer treatments (94640) and is also receiving Milrinone via continuous inhalation treatment with aerogen generator. The patient receives the continuous Milrinone 24 hrs/day x 5 days. The Milrinone runs for six hours and then is changed out with new pre-loaded syringe.
Is the continuous inhalation treatment; first hour 94644, billed on the first day of the five-day run, billed once per day for the 5 days, or billed each time the continuous treatment is changed out (every 6 hours)? The answer to the above question will then answer how to bill 94645 continuous inhalation treatment; each additional hour.
