Conversion Tables (for use with ICD-10-CA/CCI) Core

The conversion tables translate the new standard classification diagnosis and procedure codes back down to the previous classification standard diagnosis and procedure codes. The tables contain all the ICD-10-CA and CCI codes found in the validation tables by fiscal year as well as their corresponding translation to the previous classifications.

Elements included - The tables are available for either diagnosis or intervention codes. They contain the valid ICD-10-CA and CCI codes by fiscal year and the corresponding valid 1999 version* of ICD-9, ICD-9-CM and CCP. No code titles or descriptions are provided.

* Please note that the ICD-9-CM Coding Clinic errata posted after 1999 will not be incorporated in the conversion tables.

Uses - Although CIHI conversion tables can be used to convert diagnosis and interventions to their previously used classifications (ICD-9-CM or ICD-9/CCP),caution must be taken before using and/or analyzing data based on conversions. The translations provided in the tables are a result of CIHI's analysis of related coding guidelines, context of collection, and in some cases, the best force fit possible given the shift to more specific new classification standards. The focus of the tables is on collapsing ICD-10-CA and CCI down to ICD-9-CM, ICD-9 and CCP; use of the tables in the other direction is not recommended.

Caution - Variability is likely to exist in the trending analysis for specific diagnoses or interventions when comparing data pre- and post-implementation of ICD-10-CA/CCI. Since the inaugural year, these tables have undergone significant changes. They are fiscal-year specific and must be used only with the same fiscal year of data unless otherwise stated.
