ICD-10-AM Fourth Edition Mapping Tables
The term mapping refers to the process of finding an equivalent
code between two classifications enabling interpretation of one
classification in terms of another (National Coding Centre, Coding
Matters, Vol. 2,
No.4 April 1996). Mapping highlights differences between different
versions of a classification, such as: deleted codes, new codes,
expanded or more specific codes.
Mappings between classifications can be described
as forward mappings or backward mappings
Forward mapping is
where a code from a classification is mapped to a code in a more
recent or more relevant classification, for example:
- ICD-10 to ICD-10-AM First Edition
- ICD-10-AM Fourth Edition to ICD-10-AM/ACHI/ACS Fifth Edition
Backward mapping
is where a code from a new classification is mapped to a code
in an older classification or previous version of a classification,
for example:
- ICD-10-AM First Edition to ICD-10
- ICD-10-AM/ACHI/ACS Fifth Edition to ICD-10-AM Fourth Edition
