icd 10 cm extension with icd 9 diagnosis codes to support integrated access to clinical legacy data
International Journal of Medical Informatics, 2019Co-Authors: G Hernandezibarburu, David Perezrey, E Alonsooset, Raul Alonsocalvo, K De Schepper, Laura Meloni, Brecht ClaerhoutAbstract:Abstract Introduction ICD is currently the most widely used terminology to code diagnosis and procedures. The transition from ICD-9-CM to ICD-10-CM became effective on October 1, 2015 in US and many other countries. Projects that use this codification for research purposes, requires advanced methods to exploit data with both versions of ICD. Although the General Equivalence Mappings (GEMs), provided by the Centers for Medicare and Medicaid Services, might help to overcome these challenges, their direct use as translation mappings is not possible, mostly due to the further specificity of ICD-10-CM concepts. Objective We propose a methodology to generate an extended version of ICD-10-CM with selected ICD-9-CM diagnosis codes. Methods The extension was generated using the GEMs relations between concepts of both terminologies and the hierarchical relations of ICD-10-CM. Results This extended ICD-10-CM, together with modifications to the mapping of ICD-9-CM concepts that were not inserted, allows the generation of an improved translation of legacy data, raising the number of 1-to-1 correspondences by +13.81%. Conclusion The extended ICD-10-CM enables the accurate integration of ICD-9-CM and ICD-10-CM diagnosis data into a single terminology. With such analysis of data possible without having to specify both ICD-9-CM and ICD-10-CM separately for each query.

icd 10 pcs extension with icd 9 procedure codes to support integrated access to clinical legacy data
International Journal of Medical Informatics, 2019Co-Authors: G Hernandezibarburu, David Perezrey, E Alonsooset, Raul Alonsocalvo, Brecht Claerhout, D Voets, Christina Mueller, N V CustodixAbstract:Since the creation of The International Classification of Diseases (ICD), new versions have been released to keep updated with the current medical knowledge. Migrations of Electronic Health Records (EHR) from ICD-9 to ICD-10-PCS as clinical procedure codification system, has been a significant challenge and involved large resources. In addition, it created new barriers for integrated access to legacy medical procedure data (frequently ICD-9 coded) with current data (frequently ICD-10-PCS coded). This work proposes a solution based on extending ICD-10-PCS with a subgroup of ICD-9-CM concepts to facilitate such integrated access. The General Equivalence Mappings (GEMs) has been used as foundation to set the terminology relations of these inserted concepts in ICD-10-PCS hierarchy, but due to the existence of 1-to-many mappings, advanced rules are required to seamlessly integrate both terminologies. With the generation of rules based on GEMs relationships, 2014 ICD-9 concepts were included within the ICD-10-PCS hierarchy. For the rest of the concepts, a new method is also proposed to increase 1-to-1 mappings. As results, with the suggested approach, the percentage of ICD-9-CM procedure concepts that can be mapped accurately (avoiding mappings to a large number of concepts) rise from 11.56% to 69.01% of ICD-9-Proc, through the extended ICD-10-PCS hierarchy.

Development of the ICD-10 procedure coding system (ICD-10-PCS).
Topics in health information management, 2001Co-Authors: Richard F. Averill, Robert L. Mullin, Barbara A. Steinbeck, Norbert Goldfield, Thelma M. GrantAbstract:The International Classification of Diseases 10th Revision Procedure Classification System (ICD-10-PCS) has been developed as a replacement for Volume 3 of the International Classification of Diseases 9th Revision. The development of ICD-10-PCS was funded by the U.S. Health Care Financing Administration. ICD-10-PCS has a multi-axial seven character alphanumerical code structure, which provides a unique code for all substantially different procedures and which allows new procedures to be easily incorporated as new codes. ICD-10-PCS was under development for over five years and the initial draft was formally tested and evaluated by an independent contractor. The final version of the ICD-10-PCS was released in the spring of 1998. The design, development and testing of ICD-10-PCS are discussed.

Impact of the transition to ICD-10 on Medicare inpatient hospital payments.
Medicare & Medicaid Research Review, 2011Co-Authors: Ronald E. Mills, Rhonda R. Butler, Elizabeth C. Mccullough, Mona Z. Bao, Richard F. AverillAbstract:Since 1979, the U.S. has used the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) to report diagnosis data across all sites of service and procedure data for inpatient care. On October 1, 2013, ICD-9-CM will be replaced by the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) to report diagnosis data across all sites of service, and the International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) to report inpatient procedure data. ICD-10-CM/PCS substantially increases the level of clinical detail that can be captured and reported. In the FY 2009 update of ICD-9-CM, there were 14,025 diagnosis codes and 3,824 procedure codes. In the FY 2010 update of ICD-10-CM, there were 69,101 diagnosis codes and in ICD-10-PCS there were 71,957 procedure codes. For brevity ICD-10-CM/PCS will be referred to as ICD-10. Since diagnosis and procedure based patient classification systems, such as the Diagnosis Related Groups (DRGs), are used in payment methodologies, payers must adapt their payment systems to ICD-10. Payers can either directly convert their payment systems to be based on ICD-10 codes or use a mapping system, such as the Reimbursement Map from the Centers for Medicare & Medicaid Services (CMS), to convert reported ICD-10 codes to ICD-9-CM and then process the converted codes using ICD-9-CM based applications. Under a mapping approach, as providers submit claims with ICD-10 codes, the payer would map each code to an equivalent ICD-9-CM code (or codes) so existing ICD-9-CM based payment applications could continue to be used by the payer. In many areas, ICD-10 classifies clinical conditions and procedures differently from ICD-9-CM. As a result, the conversion of complex payment methodologies, or the use of maps from ICD-10 to ICD-9-CM, could have an unintended impact on aggregate payments to providers or the distribution of payments across providers. Medicare uses the Medicare Severity-Diagnosis Related Groups (MS-DRGs) as the basis of payment in the Medicare inpatient prospective payment system (IPPS). CMS has posted an ICD-10 version of MS-DRGs on its Web site (Centers for Medicare & Medicaid Services [CMS], 2010a). The availability of both versions of MS-DRGs can provide the basis for quantifying the impact on aggregate payments to hospitals, and the distribution of payments across hospitals, arising from the conversion of MS-DRGs to ICD-10. In addition, CMS has posted an ICD-10 to ICD-9-CM Reimbursement Map on its Web site (CMS, 2010b). The Reimbursement Map selects a single ICD-9-CM coding alternative that represents the most reasonable match for each ICD-10 code for the purpose of MS-DRG assignment. The availability of the reimbursement map can provide the basis for quantifying the impact on aggregate payments to hospitals, and the distribution of payments across hospitals, resulting from the use of the ICD-9-CM version of the MS-DRGs with mapped ICD-10 data. This paper uses the ICD-9-CM MS-DRG v27 (FY 2010), the converted ICD-10 MS-DRG v27, and the ICD-10 to ICD-9-CM Reimbursement Map for fiscal year 2010, to estimate the impact on aggregate payments to hospitals and the distribution of payments across hospitals. Payments based on the MS-DRGs assigned using ICD-9-CM coded data with the ICD-9-CM version of the MS-DRGs are compared to: Payments based on the MS-DRGs assigned using ICD-10 coded data with the ICD- 10 version of the MS-DRGs. Payments based on the MS-DRGs assigned using ICD-10 coded data converted back to ICD-9-CM, using the Reimbursement Map with the ICD-9-CM version of the MS-DRGs.
