Mapping tools

Files to help with mapping between ICD versions.

Mapping tables provide a link between two editions of a classification. There are two types of mapping tables provided in the ICD-10-AM and ACHI maps: 

  • Backward maps – provides equivalent code for new codes in the newer edition
  • Forward maps – provides equivalent codes for deleted codes in the newer edition

Both of these types of maps are created using logical maps.  Logical mapping is used to interpret the coded data for the best match from the AR-DRG classification. 

For mapping table inquiries or to obtain mapping tables for ICD-10-AM and ACHI Sixth to Eleventh Edition please contact the clinical coding helpdesk. Email the Coding Helpdesk
