The Medical Services / Physician Claims data contain only one diagnosis code per record, relevant to the reason for the visit to the physician. At MCHP, complications can be included or excluded in the Elixhauser Comorbidity Index algorithm. = "2" (post-admit comorbidity) in the data beginning on Ap(for use with ICD-10 codes). = "C" (complication) in the data prior to Ap(for use with ICD-9-CM codes) or by a Is used to identify whether the diagnosis is considered a comorbidity (pre-existing condition) or a complication (a condition arising during the hospital stay). For each diagnosis recorded in the hospital data, a corresponding variable called
Hospital data contains all the relevant diagnoses during an episode of care as an inpatient. Medical Services / Physician Claims data. The diagnosis codes required for use in the Elixhauser Comorbidity Index are available in the Source of Diagnosis Codes for the Elixhauser Comorbidity Index The Elixhauser Comorbidity Index developed at MCHP can be used to measure the comorbidity of individual episodes of hospital care or it can be used to create a longitudinal index based on multiple hospital episodes and medical services / physician claims over time, if so desired, depending on the purpose of the specific research project. It identifies the source of diagnosis codes in the MCHP Data Repository and how they are relevant for use in the Elixhauser Comorbidity algorithm, describes and provides access to the SAS code that is available at MCHP for running the Elixhauser Comorbidity Index and calculating the Index score, and lists the published MCHP research that have used the Elixhauser Comorbidity Index and briefly describes how it was used in the research. This section describes the use of the Elixhauser Comorbidity Index at MCHP. Use of the Elixhauser Comorbidity Index at MCHP Historical Research Perspective on the Elixhauser Comorbidity Index The list of specific ICD diagnosis codes that are used to identify different categories of comorbidity have been modified and updated from ICD-9-CM to work with ICD-10 codingĪ weighting algorithm was developed, based on the association between comorbidity and death, in order to produce an overall score for the Elixhauser Indexįor more information on these changes, please read the section titled The original Index was developed with 30 categories Over time, there have been changes to the Index based on different research. The Index can be used to predict hospital resource use and in-hospital mortality Each comorbidity category is dichotomous - it is either present or it is not.
International Classification of Diseases (ICD)ĭiagnosis codes found in administrative data, such as hospital abstracts data. The Elixhauser Comorbidity Index is a method of categorizing The concept also includes access to different versions of SAS® code for running the Elixhauser Comorbidity Index.ĭescription of the Elixhauser Comorbidity Index This concept contains information on the Elixhauser Comorbidity Index including: a basic description of the Elixhauser Comorbidity Index, how the Index is used at MCHP, and a brief historical perspective on the development and changes to the Index over time as presented in different research.
