We are adding reconstructed replication competent forms of the 1918 pandemic influenza virus containing any portion of the coding regions of all eight gene segments to the list of HHS select agents and toxins. We are taking this action for several reasons. First the pandemic influenza virus of 1918-19 killed up to 50 million people worldwide, including an estimated 675,000 deaths in the United States. Also, the complete coding sequence for the 1918 pandemic influenza A H1N1 virus was recently identified, which will make it possible for those with knowledge of reverse genetics to reconstruct this virus. In addition, the first published study on a reconstructed 1918 pandemic influenza virus demonstrated the high virulence of this virus in cell culture, embryonated eggs, and in mice relative to other human influenza viruses. Therefore, we have determined that the reconstructed replication competent forms of the 1918 pandemic influenza virus containing any portion of the coding regions of all eight gene segments have the potential to pose a severe threat to public health and safety. 相似文献

This interim final rule with comment period revises the existing effective date by which all organ procurement organizations (OPOs), rural health clinics (RHCs), Federally qualified health centers (FQHCs), and community mental health centers (CMHCs) are required to submit their Medicare cost reports in a standardized electronic format from cost reporting periods ending on or after December 31, 2004 to cost reporting periods ending on or after March 31, 2005. This interim final rule with comment does not affect the current cost reporting requirement for hospices and end-stage renal disease (ESRD) facilities. Hospices and ESRD facilities are required to continue to submit cost reports under the Medicare regulations in a standardized electronic format for cost reporting periods ending on or after December 31, 2004. 相似文献

This final rule provides a mechanism for us to expeditiously make changes to the durable medical equipment regional carrier (DMERC) service area boundaries without notice and comment rulemaking. Through this mechanism, we can change the geographical boundaries served by the regional contractors that process durable medical equipment claims through issuance of a Federal Register notice and make other minor changes in the contract administration of the DMERCs. The mechanism provides a method for increasing or decreasing the number of DMERCs, changing the boundaries of DMERCs based on criteria other than the boundaries of the Common Working File sectors, and awarding new contractors to perform statistical analysis or maintain the national supplier clearinghouse. We will publish these changes and their justifications in a Federal Register notice, rather than through notice and comment rulemaking. Although we may change the number and configuration of regional carriers, we are not altering the criteria and factors that we use in awarding contracts. Through this final rule, we are improving the contracting process so that we can swiftly meet the challenges of the changing healthcare industry and address the changing needs of beneficiaries, suppliers, and the Medicare program. 相似文献

This final rule establishes the standard for a unique health identifier for health care providers for use in the health care system and announces the adoption of the National Provider Identifier (NPI) as that standard. It also establishes the implementation specifications for obtaining and using the standard unique health identifier for health care providers. The implementation specifications set the requirements that must be met by "covered entities": Health plans, health care clearinghouses, and those health care providers who transmit any health information in electronic form in connection with a transaction for which the Secretary has adopted a standard (known as "covered health care providers"). Covered entities must use the identifier in connection with standard transactions. The use of the NPI will improve the Medicare and Medicaid programs, and other Federal health programs and private health programs, and the effectiveness and efficiency of the health care industry in general, by simplifying the administration of the health care system and enabling the efficient electronic transmission of certain health information. This final rule implements some of the requirements of the Administrative Simplification subtitle F of the Health Insurance Portability and Accountability Act of 1996 (HIPAA). 相似文献

This final rule changes the way we calculate interest on Medicare overpayments and underpayments to providers, suppliers, health maintenance organizations, competitive medical plans, and health care prepayment plans to be more reflective of current business practices. This change reduces the amount of interest assessed on overpayments and underpayments and simplifies the way the interest is calculated. This change in the way we calculate interest also applies to Medicare Secondary Payer debt. 相似文献

This final rule removes the written statement of intent (SOI) procedures, set forth in 42 CFR 424.45, used to extend the time for filing Medicare claims. In the absence of an SOI, providers and suppliers (and, where applicable, beneficiaries) have from 15 to 27 months (depending on the date of service) to file claims with Medicare contractors. 相似文献
