POLICY.........PG0041 EFFECTIVE......01/01/12 LAST REVIEW... 04/22/16 MEDICAL POLICY Genetic Testing GUIDELINES This policy does not certify benefits or authorization of benefits, which is designated by each individual policyholder contract. Paramount applies coding edits to all medical claims through coding logic software to evaluate the accuracy and adherence to accepted national standards. This guideline is solely for explaining correct procedure reporting and does not imply coverage and reimbursement. DESCRIPTION A genetic test is the analysis of human DNA, RNA, chromosomes, proteins, or certain metabolites in order to detect alterations related to a heritable or acquired disorder. This can be accomplished by directly examining the DNA or RNA that makes up a gene (direct testing), looking at markers co-inherited with a disease-causing gene (linkage testing), assaying certain metabolites (biochemical testing), or examining the chromosomes (cytogenetic testing). Clinical genetic tests are those in which specimens are examined and results reported to the provider or patient for the purpose of diagnosis, prevention or treatment in the care of individual patients. Genetic testing is performed for a variety of intended uses: Diagnostic testing (to diagnose disease) Predictive testing (generally performed to gather genetic data that can assist in clinical management, including therapeutic decision for an individual. Pre-symptomatic genetic testing (to predict future disease) Carrier testing (to identify carriers of genetic mutations) Prenatal testing (offered during pregnancy to identify fetuses that have certain diseases) Pre-implantation genetic testing (done in conjunction with invitro fertilization to determine whether embryos for implantation carry genes that could cause disease) Newborn screening (to test newborns shortly after birth to determine whether they have certain diseases known to cause problems with health and development) Pharmacogenetic testing (to determine the likelihood of an individual being responsive to a particular drug and/or to predict serious toxicity from a drug in order to optimize drug selection or drug dosage) Research genetic testing (used to help with research and development of gene-based therapy) Several hundred genetic tests are currently in use, and more are being developed. Although genetic testing can provide helpful information for diagnosing, treating, and preventing illness, there are limitations. For example, in a healthy patient, a positive result from a non-malignant genetic test does not always mean the patient will develop a disease. On the other hand, in some situation, a negative result does not guarantee the patient will not have a certain disorder. POLICY Some genetic testing requires prior authorization or may be non-covered. A provider must refer to the Paramount prior authorization list and specific medical policy in reference to specific tests for coverage determinations (this list may not be all-inclusive): PG0065 Colorectal Cancer Screening (81401, 81528) PG0067 Genetic Testing for Breast and Ovarian Cancers (81162, 81211, 81212, 81213, 81214, 81215, 81216, 81217, 81432, 81433, 81445, 81455) PG0125 DNA-Based Testing for Adolescent Idiopathic Scoliosis (AIS) (0004M) PG0280 Long QT Syndrome (LQTS) (81280, 81281, 81282, 81406) PG0287 Cell-Free DNA Tests For Fetal Aneuploidy (81420, 81507, 0009M) PG0296 Comparative Genomic Hybridization (CGH) (81228 & 81229) PG0298 Afirma Thyroid FNA Analysis (81545) PG0301 Genetic Expression Assays for Breast Cancer Prognosis (81519, 81479, 0008M) PG0302 Genetic Testing for Colorectal Cancer (81201-81203, 81292-81301, 81317-81319, 81403) PG0334 ThyroSeq (81545) PG0336 PTEN Gene Testing (81321-81323, 81432, 81435, 81436, 81445, 81455)

- 3 - Cytogenetic studies (88230-88299) do not require prior authorization for all product lines. Code 88271 has a limit of 25 units per 365 days. Proprietary MAA codes 0001M-0004M, 0006M, 0007M, 0009M, 0010M are non-covered for all product lines.,, Coverage and authorization for genetic testing is determined by review. The testing must have direct effect on the management and clinical care of the individual being tested, and must contain all of the following criteria: The genetic disorder is associated with a significant disability or has a lethal natural history The risk of the significant disability or lethality from the genetic disorder cannot be determined through other diagnostic testing A specific mutation, or set of mutations, has been proven valid in the scientific literature to be reliable, associated with the disease The results of the genetic test could impact the medical management of the individual being tested The genetic test will likely result in an anticipated improvement in net health outcomes for the individual being tested (i.e. the disease is treatable or preventable) When requesting prior authorization review, the patient s medical history/record and details of the lab facility providing the requested service must be provided. An approved request will only be given to a specific lab for a specific provider for a specific service. Genetic testing may be denied as experimental or not medically necessary based on the information submitted. The physician, lab or facility ordering the service will be financially responsible if prior authorization is not obtained. Members who choose to proceed with unauthorized genetic testing bear the responsibility for the cost. The provider should always secure a Waiver of Responsibility prior to providing the testing to assure member understanding of their financial responsibility. While most genetic testing requires prior authorization, the following services have been reviewed by The Plan s medical staff with the determination that they are not medically supported and therefore are non-covered (this list may not be all-inclusive): PG-0111 VeriStrat (81538) PG-0119 DecisionDX-UM PG0122 In Vitro Chemoresistance and Chemosensitivity Assays (81535, 81536) PG0181 Topographic Genotyping Paramount covers cytogenetic studies (88230-88299) when they are reasonable and necessary for the diagnosis or treatment of the following conditions: Genetic disorders (e.g., mongolism) in a fetus Failure of sexual development Chronic myelogenous leukemia Acute leukemias lymphoid (FAB L1-L3), myeloid (FAB M0-M7), and unclassified Mylodysplasia NOTE: Molecular cytogenetics; DNA probe each (88271) will have a limit of 25 units per 365 days.
