Reassessment Date determined at Companies sole discretion: 12/30/2021 POLICY ADDENDUM COVID-19 Public Health Emergency On March 30th, 2020, the Centers for Medicare & Medicaid Services (CMS) released “Physicians and Other Clinicians: CMS Flexibilities to Fight COVID-19”, which states: National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs) on Respiratory Related Devices, Oxygen and Oxygen Equipment, Home Infusion Pumps and Home Anticoagulation Therapy: Clinicians now have maximum flexibility in determining patient needs for respiratory related devices and equipment and the flexibility for more patients to manage their treatments at the home. The current NCDs and LCDs that restrict coverage of these devices and services to patients with certain clinical characteristics do not apply during the public health emergency. For example, Medicare will cover non-invasive ventilators, respiratory assist devices and continuous positive airway pressure devices based on the clinician’s assessment of the patient. Page 1 of 11 MP88 MEDICAL POLICY Home Oxygen Therapy and Equipment for Lung Disease or Hypoxia (All Lines of Business Except Medicare) Therefore, beginning 3/30/2020, the Medicare Guidelines below do not apply during this public health emergency. During this time, the DME addressed in this medical policy will be covered based on the clinician’s assessment of the patient. SCOPE: Providence Health Plan, Providence Health Assurance, Providence Plan Partners, and Ayin Health Solutions as applicable (referred to individually as “Company” and collectively as “Companies”). APPLIES TO: All lines of business except Medicare BENEFIT APPLICATION Medicaid Members Oregon: Services requested for Oregon Health Plan (OHP) members follow the OHP Prioritized List and Oregon Administrative Rules (OARs) as the primary resource for coverage determinations. Medical policy criteria below may be applied when there are no criteria available in the OARs and the OHP Prioritized List. POLICY CRITERIA Note: This policy does not address home oxygen therapy and oxygen equipment in patients under 18 years of age. This policy is based on the following Centers for Medicare & Medicaid guidelines: • National Coverage Determination (NCD) 240.2: Home Use of Oxygen1 • Local Coverage Determination (LCD) L33797: Oxygen and Oxygen Equipment2 • Local Coverage Article (LCA) A52514: Oxygen and Oxygen Equipment3 Home Oxygen Therapy I. Home oxygen therapy and oxygen equipment for severe lung disease or hypoxia-related symptoms may be considered medically necessary and covered if the following conditions are met (I.A-E): A. The treating practitioner has determined that the member has a severe lung disease or hypoxia-related symptoms that might be expected to improve with oxygen therapy; and Page 2 of 11 MP88 MEDICAL POLICY Home Oxygen Therapy and Equipment for Lung Disease or Hypoxia (All Lines of Business Except Medicare) B. The member meets the standards of a qualified blood gas study (for definition of qualifying blood gas study, see the Policy Guidelines section), measured through either an oximetry test or an arterial blood gas test; and C. The qualifying blood gas test was performed by a treating practitioner or by a qualified provider or supplier of laboratory services; and D. The qualifying blood gas study was obtained under the following conditions: 1. If the qualifying blood gas study is performed during an inpatient hospital stay, the reported test must be the one obtained closest to, but no earlier than 2 days prior to the hospital discharge date, or 2. If the qualifying blood gas study is not performed during an inpatient hospital stay, the reported test must be performed while the beneficiary is in a chronic stable state – i.e., not during a period of acute illness or an exacerbation of their underlying disease, and E. Alternative treatment measures have been tried or considered and deemed clinically ineffective. II. Home oxygen therapy and oxygen equipment for severe lung disease or hypoxia-related symptoms is considered not medically necessary and not covered when criterion I above is not met. Portable Oxygen Systems III. A portable oxygen system may be considered medically necessary and covered if the member is mobile within the home and the qualifying blood gas study was performed while at rest (awake) or during exercise. IV. Portable oxygen is considered not medically necessary and not covered If the only qualifying blood gas study was performed during sleep. NON-COVERAGE CRITERIA V. Group III includes beneficiaries with arterial PO 2 levels at or above 60 mm Hg or arterial blood oxygen saturations at or above 90 percent. For these beneficiaries there is a rebuttable presumption of non-coverage. VI. If the coverage conditions specified above are not met, the oxygen therapy will be denied as not reasonable and necessary. Oxygen therapy will also be denied as not reasonable and necessary if any of the following conditions are present (VI.1-4): A. Angina pectoris in the absence of hypoxemia. This condition is generally not the result of a low oxygen level in the blood and there are other preferred treatments. B. Dyspnea without cor pulmonale or evidence of hypoxemia Page 3 of 11 MP88 MEDICAL POLICY Home Oxygen Therapy and Equipment for Lung Disease or Hypoxia (All Lines of Business Except Medicare) C. Severe peripheral vascular disease resulting in clinically evident desaturation in one or more extremities but in the absence of systemic hypoxemia. There is no evidence that increased PO 2 will improve the oxygenation of tissues with impaired circulation. D. Terminal illnesses that do not affect the respiratory system VII. Emergency or stand-by oxygen systems for members who are not regularly using oxygen are considered not medically necessary and are not covered since they are precautionary and not therapeutic in nature. VIII. Topical hyperbaric oxygen chambers (A4575) are considered not medically necessary and are not covered. IX. Topical oxygen delivery systems (E0446) are considered not medically necessary and are not covered. POLICY GUIDELINES Standards for qualifying blood gas study: A qualifying blood bag study can be defined in two ways, through Group I or Group II criteria: Group I criteria include any of the following: • An arterial PO2 at or below 55 mm Hg or an arterial oxygen saturation at or below 88 percent taken at rest (awake), or • An arterial PO2 at or below 55 mm Hg, or an arterial oxygen saturation at or below 88 percent, for at least 5 minutes taken during sleep for a beneficiary who demonstrates an arterial PO2 at or above 56 mm Hg or an arterial oxygen saturation at or above 89 percent while awake, or • A decrease in arterial PO2 more than 10 mm Hg, or a decrease in arterial oxygen saturation more than 5 percent from baseline saturation, for at least 5 minutes taken during sleep associated with symptoms (e.g., impairment of cognitive processes and [nocturnal restlessness or insomnia]) or signs (e.g., cor pulmonale, "P" pulmonale on EKG, documented pulmonary hypertension and erythrocytosis) reasonably attributable to hypoxemia, or • An arterial PO2 at or below 55 mm Hg or an arterial oxygen saturation at or below 88 percent, taken during exercise for a beneficiary who demonstrates an arterial PO2 at or above 56 mm Hg or an arterial oxygen saturation at or above 89 percent during the day while at rest. In this case, oxygen is provided for during exercise if it is documented that the use of oxygen improves the hypoxemia that was demonstrated during exercise when the beneficiary was breathing room air. Page 4 of 11 MP88 MEDICAL POLICY Home Oxygen Therapy and Equipment for Lung Disease or Hypoxia (All Lines of Business Except Medicare) Initial coverage for beneficiaries meeting Group I criteria is limited to 12 months or the treating practitioner-specified length of need, whichever is shorter. Group II criteria include the presence of: • An arterial PO2 of 56-59 mm Hg or an arterial blood oxygen saturation of 89 percent at rest (awake), during sleep for at least 5 minutes, or during exercise (as described under Group I criteria), and any of the following: o Dependent edema suggesting congestive heart failure, or o Pulmonary hypertension or cor pulmonale, determined by measurement of pulmonary artery pressure, gated blood pool scan, echocardiogram, or "P" pulmonale on EKG (P wave greater than 3 mm in standard leads II, III, or AVF), or o Erythrocythemia with a hematocrit greater than 56 percent. Initial coverage for beneficiaries meeting Group II criteria is limited to 3 months or the treating practitioner specified length of need, whichever is shorter. BILLING GUIDELINES A maximum of 3 months of oxygen may be delivered at any one time. Initial 36 Months Reimbursement for oxygen equipment is limited to 36 monthly rental payments.

  • How Is Pulmonary Fibrosis Diagnosed?
    How Is Pulmonary Fibrosis Diagnosed? Pulmonary fibrosis (PF) may be difficult to diagnose as the symptoms of PF are similar to other lung diseases. There are many different types of PF. If your doctor suspects you might have PF, it is important to see a specialist to confirm your diagnosis. This will help ensure you are treated for the exact disease you have. Health History and Exam Your doctor will perform a physical exam and listen to your lungs. • If your doctor hears a crackling sound when listening to your lungs, that is a sign you might have PF. • It is also important for your doctor to gather detailed information about your health. ⚪ This includes any family history of lung disease, any hazardous materials you may have been exposed to in your lifetime and any diseases you’ve been treated for in the past. Imaging Tests Tests like chest X-rays and CT scans can help your doctor look at your lungs to see if there is any scarring. • Many people with PF actually have normal chest X-rays in the early stages of the disease. • A high-resolution computed tomography scan, or HRCT scan, is an X-ray that provides sharper and more detailed pictures than a standard chest X-ray and is an important component of diagnosing PF. • Your doctor may also perform an echocardiogram (ECHO). ⚪ This test uses sound waves to look at your heart function. ⚪ Doctors use this test to detect pulmonary hypertension, a condition that can accompany PF, or abnormal heart function. Lung Function Tests There are several ways to test how well your lungs are working.

Sánchez-Medina2, María Dolores Ochoa Vázquez3, Simón Barquera Cervera1 and Luis Gerardo Ochoa Jiménez1 1Pulmonology Department, Centro Médico Nacional La Raza, IMSS, Morelia, Mich., Mexico; 2Health Science, 3Jefe del servicio de Neumología, Centro Médico Nacional La Raza, IMSS, Morelia, Mich., Mexico Abstract Introduction: Obesity is a disease that is closely associated with deleterious respiratory effects such as the Obesity Hy- poventilation Syndrome which conventionally includes awake hypercapnia. There are studies addressing the detection of daytime hypercapnia with the patient either in sitting or standing position. However, there are no studies in obese subjects with a normal daytime PaCO2 in whom the detection of hypercapnia is made in the supine position. It is feasible that the physiopathological changes that occur in obese patients when they adopt the supine position lead to increased PaCO2 levels or hypercapnia. Objective: To determine the levels of PaCO2 in obese patients with a normal daytime PaCO2 in the supine position using arterial blood gas test. Methods: Fifty patients with BMI > 30 Kg/m², with a normal daytime PaCO2 were included. Daytime arterial blood gas test was performed first with the patient in a standing position along with pulmonary function test. A second arterial blood gas test was made 15 minutes after the patient adopted the supine position.

  • Virtual Autopsy in Legal Medicine: Literature Review and Example of Application on the Mummified Remains
    MEDICINE, LAW & SOCIETY Vol. 11, No. 2, pp. 67-90 , October 2018 Virtual Autopsy in Legal Medicine: Literature Review and Example of Application on the Mummified Remains IVANA KRUŽIĆ, IVAN JERKOVIĆ, FRANE MIHANOVIĆ, ANA MARUŠIĆ, ŠIMUN ANĐELINOVIĆ & ŽELJANA BAŠIĆ Abstract The virtual autopsy and post-mortem imaging methods are relatively novel methods used in medicine to determine cause and manner of death. They can also be exceptionally useful in the process of identification. Although they have numerous advantages, they are still not implemented in practice to a sufficient extent because the methodology has not yet been validated, and studies that deal with legal and practical implications of those methods are relatively scarce. In this article we describe basic principles and advantages of the methodology, explore related legal and practical issues, and present a case of virtual autopsy in practice on the mummified remains of St. Ivan Olini from Church of St. Blaise in Vodnjan (Croatia).

  • Chapter 6: Clinical Presentation of Venous Thrombosis “Clots”
    CHAPTER 6 CLINICAL PRESENTATION OF VENOUS THROMBOSIS “CLOTS”: DEEP VENOUS THROMBOSIS AND PULMONARY EMBOLUS Original authors: Daniel Kim, Kellie Krallman, Joan Lohr, and Mark H. Meissner Abstracted by Kellie R. Brown Introduction The body has normal processes that balance between clot formation and clot breakdown. This allows clot to form when necessary to stop bleeding, but allows the clot formation to be limited to the injured area. Unbalancing these systems can lead to abnormal clot formation. When this happens clot can form in the deep veins usually, but not always, in the legs, forming a deep vein thrombosis (DVT). In some cases, this clot can dislodge from the vein in which it was formed and travel through the bloodstream into the lungs, where it gets stuck as the size of the vessels get too small to allow the clot to go any further. This is called a pulmonary embolus (PE). This limits the amount of blood that can get oxygen from the lungs, which then limits the amount of oxygen that can be delivered to the rest of the body. How severe the PE is for the patient has to do with the size of the clot that gets to the lungs. Small clots can cause no symptoms at all. Very large clots can cause death very quickly. This chapter will describe the symptoms that are caused by DVT and PE, and discuss the means by which these conditions are diagnosed. What are the most common signs and symptoms of a DVT? The symptoms that are caused by DVT depend on the location and extent of the clot.

  • Clinical Utility of Arterial Blood Gas Test in an Intensive Care Unit: an Observational Study Jagadish Chandran1 , Carol D’Silva2 , Sampath Sriram3 , Bhuvana Krishna4
    ORIGINAL ARTICLE Clinical Utility of Arterial Blood Gas Test in an Intensive Care Unit: An Observational Study Jagadish Chandran1 , Carol D’Silva2 , Sampath Sriram3 , Bhuvana Krishna4 ABSTRACT Background: Arterial blood gas (ABG) analysis is a common test ordered in critically ill patients. Often, it is performed very frequently without influencing patient care. Hence, we decided to check the utility of the ABG test in our intensive care unit (ICU). Materials and methods: The data of the previous day ABGs were captured by reviewing the chart in an online pro forma which was filled by the authors. Data relating to patient’s details, who ordered ABGs, reason for ordering ABGs, and did the ABG influence patient’s management were entered. A total of 985 ABGs were performed in 173 patients for 2 months which was analyzed. Results: Out of 985 ABGs, in 259 instances (26.29%), interventions were done after reviewing an ABG. The major interventions among these ABGs were ventilator settings adjustment in 134 ABGs (13.6%). A total of 790 ABGs were done routinely with no specific indication (80.20%), while doctors ordered one following an event for 195 ABGs (19.80%). Conclusion: Our data suggest that 80% of ABG tests were ordered as part of a routine test. Keywords: Arterial blood gas, Arterial cannula, Clinical utility.
