Portable oxygen, therefore, would not be covered in this situation or, In either of these cases, coverage is provided only for use of oxygen during sleep, and then only one type of unit will be covered. An arterial PO2 at or below 55 mm Hg, or an arterial oxygen saturation at or below 88%, taken during sleep for a patient who demonstrates an arterial PO2 at or above 56 mm Hg, or an arterial oxygen saturation at or above 89%, while awake or a greater than normal fall in oxygen level during sleep (a decrease in arterial PO2 more than 10 mm Hg, or decrease in arterial oxygen saturation more than 5%) associated with symptoms or signs reasonably attributable to hypoxemia (e.g., impairment of cognitive processes and nocturnal restlessness or insomnia).An arterial PO2 at or below 55 mm Hg, or an arterial oxygen saturation at or below 88%, taken at rest, breathing room air or.Patients exhibiting hypoxemia are defined using the clinical criteria below: For those patients whose initial oxygen prescription does not originate during an inpatient hospital stay, the time of need is during the period when the treating practitioner notes signs and symptoms of illness that can be relieved by oxygen in the patient who is to be treated at home. For an inpatient hospital patient the time of need is within 2 days of discharge. The time of need is defined as during the patient’s illness when the presumption is that the provision of oxygen in the home setting will improve the patient’s condition. Required qualifying arterial blood gas or oximetry studies must be performed at the time of need. When the arterial blood gas and the oximetry studies are both used to document the need for home oxygen therapy and the results are conflicting, the arterial blood gas study is the preferred source of documenting medical need. This prohibition does not extend to the results of blood gas tests conducted by a hospital certified to do such tests. A durable medical equipment (DME) supplier is not considered a qualified provider or supplier of laboratory services for purposes of this National Coverage Determination (NCD). A measurement of arterial oxygen saturation obtained by ear or pulse oximetry, however, is also acceptable when ordered and evaluated by the treating practitioner and performed under his or her supervision or when performed by a qualified provider or supplier of laboratory services. Such a test is usually in the form of a measurement of the partial pressure of oxygen (PO2) in arterial blood. Initial claims for oxygen therapy for hypoxemic patients must be based on the results of a clinical test that has been ordered and evaluated by the treating practitioner. Oxygen therapy and oxygen equipment is covered in the home for acute or chronic conditions, short- or long- term, when the patient exhibits hypoxemia as defined below.
