27027 Tourney Road Valencia, CA 91355 800 421 7110 www.specialtylabs.com New Test Announcements Dear Colleague: We are pleased to announce many new test offerings this month. January 25, 2007 In oncology, the molecular-based BCL2/JH Gene Rearrangement by PCR assay is now available. BCL2/JH gene rearrangements [t(14;18) translocations] are important features distinguishing Non-Hodgkin s Lymphoma of follicular origin. BCL2/JH identified by PCR is present in 70-90% of follicular lymphomas and 20-30% of diffuse large B-cell lymphomas. In our Drugs of Abuse (DOA) test menu, several new serum and urine confirmatory tests are now available as well as new screening panels that reflex to confirmation. Specialty is pleased to offer confirmation Drugs of Abuse testing utilizing LCMS/MS methodology. Confirmatory Testing: Screens with reflex to confirmations: 4090 Benzodiazepine (serum) 4109U Methadone (urine) w/rfx 4157 Tricyclic Antidepressants (TCA) (serum) 4109 Methadone (serum) w/rfx 4154 Tricyclic Antidepressants (TCA) (serum) Extended 4101U PCP (urine) w/rfx 4092U Barbituates (urine) 4101 PCP (serum) w/rfx 4094U Propoxyphene (urine) 4107 Benzodiazepines (serum) w/rfx 4121U Barbituates (urine) w/rfx 4127U Propoxyphene (urine) w/rfx Billing update: National Provider Identifier The Administrative Simplification provisions of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) mandated the adoption of a standard unique identifier for health care providers. The National Plan and Provider Enumeration System (NPPES) collects identifying information on health care providers and assigns each a unique National Provider Identifier (NPI). HIPAA requires that covered health care providers use NPIs in standard transactions by the compliance date of May 23, 2007. It will be the only health care provider identifier that can be used in billing transactions and will be the only identifier accepted by Specialty on this date. The NPI must replace all requesting physician UPIN, provider and license numbers on requisitions submitted for Medicare, Medicaid or other third party billing. For more information regarding the NPI, please visit the following CMS website: http://www.cms.hhs.gov/nationalprovidentstand/ If you have any questions regarding this requirement, please call Judy Perez at 800-421-7110 ext. 4502. Medical Necessity/Diagnosis Codes Every third party bill must have a valid diagnosis code. Please be sure to put the ICD-9 Code(s) applicable to the patient s condition for the specified date of service on the requisition in the box marked Diagnostic Codes (ICD-9). Medicare diagnosis codes must be coded to the highest level of specificity. Please refer to the International Classification of Diseases (ICD-9) manual, as well as the Medical Regulations and Manuals issued or authorized by the Center for Medicare and Medicaid Services (CMS) for diagnosis coding rules and regulations. If the claim is denied due to lack of medical necessity, Specialty will send a request for an additional ICD-9 code or other evidence of medical necessity directly to the ordering client. If the claim is denied pending laboratory results, Specialty will send a release form directly to the patient for authorization to release laboratory results to the third party payers for HIV-related services. For additional information, please visit our Web site at www.specialtylabs.com or contact Client Relations at 800-421-4449. Michael C. Dugan, M.D. Vice President and Laboratory Director
