Question: How would you answer M0500 (Respiratory treatments used at home) if the patient is using a Bi-PAP machine? Answer: Select 4 (None of the above), the Centers for Medicare & Medicaid Services instructs in its OASIS questions and answers. The response specific instructions for M0500 tell you to exclude any respiratory treatments that are not specifically listed in the item, CMS says. So unless the patient uses any of the other listed items, select answer four. But document the Bi-PAP use in the patient's medical record, CMS adds.
1. Oxygen (intermittent or continuous)
2. Ventilator (continually or at night)
3. Continuous positive airway pressure
4. None of the above
