Certain Cigna Companies and/or lines of business only provide utilization review services to clients and do not make coverage determinations. References to standard benefit plan language and coverage determinations do not apply to those clients. Coverage Policies are intended to provide guidance in interpreting certain standard benefit plans administered by Cigna Companies. Please note, the terms of a customer’s particular benefit plan document [Group Service Agreement, Evidence of Coverage, Certificate of Coverage, Summary Plan Description (SPD) or similar plan document] may differ significantly from the standard benefit plans upon which these Coverage Policies are based. For example, a customer’s benefit plan document may contain a specific exclusion related to a topic addressed in a Coverage Policy. In the event of a conflict, a customer’s benefit plan document always supersedes the information in the Coverage Policies. In the absence of a controlling federal or state coverage mandate, benefits are ultimately determined by the terms of the applicable benefit plan document. Coverage determinations in each specific instance require consideration of 1) the terms of the applicable benefit plan document in effect on the date of service; 2) any applicable laws/regulations; 3) any relevant collateral source materials including Coverage Policies and; 4) the specific facts of the particular situation. Each coverage request should be reviewed on its own merits. Medical directors are expected to exercise clinical judgment and have discretion in making individual coverage determinations. Coverage Policies relate exclusively to the administration of health benefit plans. Coverage Policies are not recommendations for treatment and should never be used as treatment guidelines. In certain markets, delegated vendor guidelines may be used to support medical necessity and other coverage determinations. Overview This Coverage Policy (CP) addresses nucleic acid infectious pathogen testing. Infectious pathogen testing using nucleic acid laboratory methods identifies the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) of disease-causing microorganisms, including viruses, bacteria and fungi, including yeast, for the purpose of diagnosis and treatment. The scope of this Coverage Policy (CP) includes medically appropriate indications for nucleic acid infectious pathogen testing for selected pathogens, including testing of single or multiple pathogen targets. Indications addressed within the scope of this CP include testing for chlamydia, candida, gardnerella vaginalis, gonorrhea, genital herpes (herpes simplex virus [HSV], type 1 and 2), high-risk human papillomavirus (HPV), onychomycosis, nail dystrophy, syphilis, tineas, trichomonas, respiratory, gastrointestinal and central nervous system pathogen panels, nucleic acid testing to identify pathogens related to urinary tract infection and nucleic Page 1 of 37 Medical Coverage Policy: 0530 Effective 9/15/2021 acid quantification.

General Background The purpose of infectious pathogen testing using nucleic acid laboratory methods is to identify the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) of disease-causing microorganisms, including viruses, bacteria and fungi, including yeast, for the purpose of diagnosis and treatment. Nucleic acid pathogen testing provides sensitive, specific and timely identification of microorganisms. A nucleic acid test analyzes tiny amounts of DNA or RNA in a sample of blood, tissue or body fluid. Because the amount of genetic material is very small the test may include a step where the DNA or RNA of the microorganism is amplified, or increased. This type of nucleic acid pathogen test is known as a nucleic acid amplification test or NAAT. The NAAT format increases diagnostic sensitivity by decreasing the lower limit of detection. For some pathogens there may be a need to determine the precise concentration of DNA or RNA present, rather than only detecting the presence of the microorganism. This is referred to as nucleic acid quantification. Nucleic acid pathogen testing for chlamydia trachomatis (chlamydia), gardnerella vaginalis, Neisseria gonorrhea (gonorrhea), genital herpes (herpes simplex virus [HSV] type 1 and 2), human papillomavirus (HPV), candida, syphilis and trichomoniasis (trichomonas vaginitis) may be appropriate for asymptomatic individuals with high- risk behavior (e.g., exposure to possible infected partner, high-risk conditions (e.g., pregnancy, HIV infection), or high-risk experiences (e.g., assault) or when otherwise required under the prevention provisions of the Affordable Care Act. Nucleic acid infectious pathogen testing may also be appropriate for a symptomatic individual when the associated signs and symptoms or diagnoses, are listed in the coding/billing information section of this Coverage Policy. Standard laboratory methods, such as microscopy, gram stain, culture, histology, or antibody or antigen tests are considered the gold standard to detect the presence of some microorganisms, such as gardnerella vaginalis, mucosal and noninvasive candida and syphilis. Appropriate use of nucleic acid infectious pathogen testing is informed by authoritative statements from the Infectious Diseases Society of America (IDSA), Centers for Disease Control and Prevention (CDC), American Cancer Society, Association of Public Health Laboratories, U.S. Preventive Services Task Force and the Center for Medicare and Medicaid Services, published, professional society recommendations and other published sources. Candida There are over 20 species of Candida yeasts that can cause infection in humans. Candida yeasts normally reside in the intestinal tract and can be found on mucous membranes, skin and nails, without causing infection; however, overgrowth of these organisms can cause symptoms to develop. Symptoms of candidiasis vary depending on the area of the body that is infected. Esophageal candidiasis is one of the most common infections in people living with HIV/AIDS. Invasive candidiasis occurs when Candida species enter the bloodstream and spread throughout the body. Unlike Page 3 of 37 Medical Coverage Policy: 0530 Effective

Konya, Turkey Dates: Received: 02 April, 2016; Accepted: 18 April, Infection Diagnosis 2016; Published: 19 April, 2016 *Corresponding author: Dr. Uğur Tüzüner, Abstract Necmettin Erbakan University, Meram Medical Faculty, Medical Microbiology Department, AIDS caused by HIV is an infection disease which was defined firstly in the USA in 1981. Since Konya, Turkey, Tel:+90 332 223 7029; E-mail: then, number of AIDS patients has increased continuously. About 36.9 million people are living with HIV around the world. Approximately 15 million people living with HIV were receiving antiretroviral therapy. Early detection is important due to the high risk of transmission that precedes seroconversion www.peertechz.com and also because it provides an opportunity to improve health outcomes with an early antiretroviral therapy. HIV testing is the key part of diagnosis and prevention efforts. Many tests have been used ISSN: 2455-3786 in the diagnosis of HIV over years and with developing testing methods, accuracy of the laboratory Keywords: HIV; Laboratory diagnosis; Algorithm diagnosis of HIV infection has been improved. Detecting p24 antigens, HIV 1-2 antibodies and HIV nucleic acid demonstrated that antibody testing alone might miss a considerable percentage of HIV infections detectable by these tests. This review provides updated recommendations and algorithm for HIV testing that are necessary for diagnosing HIV and offers approaches for accurate assessment of test results. Introduction HIV infection (asymptomatic HIV infection or clinical latency), and progression to AIDS (the late stage of HIV infection).

  • Rapid Review: Performance and Feasibility of Rapid COVID-19 Tests
    COVID-19 Scientific Advisory Group Rapid Evidence Report Do the rapid COVID-19 tests on the market represent a feasible opportunity for Alberta? 1. What are the reported performance characteristics of the rapid COVID-19 tests that have been approved for commercial (diagnostic) use in Canada? 2. What are the optimal strategies for deployment of rapid testing, to improve either clinical care or outbreak control in health care and community settings? Context • It is unclear how the rapid (point-of-care) molecular and antigen tests for COVID-19 tests compare to each other. • Five point-of-care testing devices/systems have been approved for diagnostic use by Health Canada: 1) BD Veritor System for Rapid Detection of SARS-CoV-2 (Becton Dickinson and Company) 2) BKit Virus Finder COVID-19 (Hyris Ltd.) 3) ID NOW COVID-19 (Abbott Diagnostics Scarborough Inc.) 4) Panbio COVID-19 Ag Rapid Test Device (Abbott Rapid Diagnostics) 5) Xpert Xpress SARS-CoV-2 (Cepheid). • The federal government has committed to distributing the consumables for the Abbott ID NOW and PanBio testing kits to each Canadian jurisdiction, however, the strategy for deploying the rapid test kits will be the responsibility of the public health leaders in the provincial/territorial governments. • The implementation of rapid testing in other jurisdictions offers an opportunity to learn from their experiences in deploying rapid COVID-19 tests and avoid potential missteps. These implementation activities have included mass assessments, population-level testing to determine prevalence, returned traveler assessment, staff screening at long-term care facilities, and school testing. Key Messages from the Evidence Summary • The body of evidence for rapid testing platforms is poor – many of the studies are at high risk of bias.

  • Lower Respiratory SARS-Cov-2 Testing for Lung Donors
    Notice of OPTN Emergency Policy Change Lower Respiratory SARS-CoV-2 Testing for Lung Donors Sponsoring Committee: Ad Hoc Disease Transmission Advisory Policies Affected: Policy 1.2: Definitions Policy 2.9: Required Deceased Donor Infectious Disease Testing Public Comment: August 3, 2021-September 30, 2021 Board Approved: April 26, 2021 Effective Date: May 27, 2021 Summary of Changes The policy change defines what a lower respiratory specimen is and requires that all lung donors receive lower respiratory specimen testing by nucleic acid test (NAT). The policy specifies that testing results must be available pre-transplant of lungs. Purpose of Policy Change There has been accumulating evidence of a patient safety risk to lung recipients in four recent cases of deceased lung donors testing negative for SARS-CoV-2 by upper respiratory specimen and retrospectively testing positive by lower respiratory specimen. Three cases resulted in donor-derived transmission to lung recipients while the fourth resulted in lung discard. One lung recipient has died as a result of the donor-derived transmission. As of March 2021, only 60% of lung donors were tested by lower respiratory specimen.1 Policy is needed to ensure organ procurement organizations (OPOs) perform and obtain results from lower respiratory specimen testing for all potential deceased lung donors to avoid SARS-CoV-2 (COVID-19) transmission to lung recipients. The policy change is emergent because of the significant patient safety implications of donor-derived COVID-19 and the subsequent risk of patient mortality. The policy change requires nucleic acid testing (NAT) for COVID-19 by lower respiratory specimen for all potential deceased lung donors, with results being available prior to lung transplantation.

Abstract: The coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began as a cluster of pneumonia cases in Wuhan, China before spreading to over 200 countries and territories on six continents in less than six months. Despite rigorous global containment and quarantine efforts to limit the transmission of the virus, COVID-19 cases and deaths have continued to increase, leaving devastating impacts on the lives of many with far- reaching effects on the global society, economy and healthcare system. With over 43 million cases and 1.1 million deaths recorded worldwide, accurate and rapid diagnosis continues to be a cornerstone of pandemic control. In this review, we aim to present an objective overview of the latest nucleic acid-based diagnostic tests for the detection of SARS-CoV-2 that have been authorized by the Food and Drug Administration (FDA) under emergency use authorization (EUA) as of 31 October 2020.

  • The Point-Of-Care Diagnostic Landscape for Sexually Transmitted Infections (Stis)
    The Point-of-Care Diagnostic Landscape for Sexually Transmitted Infections (STIs) Maurine M. Murtagh The Murtagh Group, LLC 2019 1 Introduction Sexually transmitted infections (STIs) continue to be a significant global public health issue, with an estimated 378 million people becoming ill in 2016 with one of 4 STIs: syphilis, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) (1) . In addition, more than 291 million women have a human papillomavirus (HPV) infection, which is a necessary cause of high grade cervical intraepithelial neoplasia (grade 2 or higher [CIN2+]) (1). This report considers the available and pipeline diagnostics for curable STIs, namely syphilis, CT, NG, TV, and HPV. With some exceptions, the existing diagnostics for these STIs are laboratory-based platforms, which typically require strong infrastructure and well-trained laboratory technicians. In addition, test turnaround time (TAT) is often long, requiring patients to return for test results on a subsequent clinic visit. This, in turn, leads to significant loss to follow-up. Therefore, while these laboratory-based diagnostics are effective, they may not always be suitable for use in resource-limited settings where diagnostic access and delivery are difficult. There are now a variety of tests available for use at or near the point of patient care (POC) for STIs (2). These include a wide range of rapid diagnostic tests (RDTs) for human immunodeficiency virus (HIV), hepatitis C virus (HCV) and syphilis, among others, with which it is possible to detect infection using fingerprick blood, or in some cases, oral fluid.1 In addition, other types of POC tests, including simple molecular tests for use in primary healthcare settings, have also become available recently.

  • Recommended Laboratory HIV Testing Algorithm for Serum Or Plasma Specimens
    Recommended Laboratory HIV Testing Algorithm for Serum or Plasma Specimens 1. Laboratories should conduct initial testing for HIV with an FDA-approved antigen/antibody combination immunoassay* that detects HIV-1 and HIV-2 antibodies and HIV-1 p24 antigen to test for established HIV-1 or HIV-2 infection and for acute HIV-1 infection. No further testing is required for specimens that are nonreactive on the initial immunoassay. 2. Specimens with a reactive antigen/antibody combination immunoassay result (or repeatedly reactive, if repeat testing is recommended by the manufacturer or required by regulatory authorities) should be tested with an FDA-approved antibody immunoassay that differentiates HIV-1 antibodies from HIV-2 antibodies. Reactive results on the initial antigen/antibody combination immunoassay and the HIV- 1/HIV-2 antibody differentiation immunoassay should be interpreted as positive for HIV-1 antibodies, HIV-2 antibodies, or HIV antibodies, undifferentiated. 3. Specimens that are reactive on the initial antigen/antibody combination immunoassay and nonreactive or indeterminate on the HIV-1/HIV-2 antibody differentiation immunoassay should be tested with an FDA-approved HIV-1 nucleic acid test (NAT). A reactive HIV-1 NAT result and nonreactive HIV-1/HIV-2 antibody differentiation immunoassay result indicates laboratory evidence for acute HIV-1 infection. A reactive HIV-1 NAT result and indeterminate HIV-1/HIV-2 antibody differentiation immunoassay result indicates the presence of HIV-1 infection confirmed by HIV-1 NAT. A negative HIV-1 NAT result and nonreactive or indeterminate HIV-1/HIV-2 antibody differentiation immunoassay result indicates a false-positive result on the initial immunoassay.
