2 By attending this workshop, participants will Identify theReasons for implementing ICD-10-CM in the United StatesSettings that will require ICD-10-CMKnowledge that coders will need to apply ICD-10-CMSimilarities between ICD-9-CM and ICD-10-CMDifferences between ICD-9-CM and ICD-10-CMReceiveICD-10-CM Coding Examples and CasesICD-10-CM Resources Listing for future use
3 Why Change to ICD-10-CM?ICD-9-CM out of space to accommodate new codesAdvances in medical knowledgeNew technologyNewly identified diseasesLimited space = Lack sufficient clinical detailSeverity or complexity of diagnoses
4 Why Change to ICD-10-CM?Updated classification system allows ability toMeasure quality of careInitiate pay-for-performanceEvaluate resource utilizationTrack public health threats, such as avian fluIdentify medical errors and patient safety issuesExchange meaningful health data with other organizations and government agencies
5 Reasons for ICD-10-CM Implementation Represents significant improvementDesigned to overcome issues & limitations ofICD-9-CMUpdates healthcare coding with unambiguous codes for conditionsMore flexibility in adding new codesHas greater specificity and clinical detailMajor improvements in quality & usefulness of coded data
6 Reasons for ICD-10-CM Implementation Updated Medical terminology & classification of diseases to reflect current clinical practiceImproved structure & capacity for capturing technological advancesMore flexibleAccommodates revisions necessitated by medical advances
7 Why Change to ICD-10-CM?ICD-10 first published by WHO1999 – Australia1999 – US for death certificate coding2000 – Canada2005 – FranceThailand2008 – Korea25 countries use ICD-10 for healthcare reimbursement & resource allocationICD-11 – development from now thru 2015
