CMS' ICD-9-CM to and from ICD-10-CM and ICD-10-PCS Crosswalk or General Equivalence Mappings

Centers for Medicare & Medicaid Services CMS has developed the ICD-9-CM to and from ICD-10-CM and ICD-10-PCS General Equivalence Mappings to make converting from ICD-9-CM to or from ICD-10-CM and ICD-10-PCS easier. Their ICD-10 page has information and data about the transition.

An easy introduction to using these files is available.

A Basic FAQ and Techincal FAQ are available.

The FAQs above make reading the Technical Documentation easier.

Jean Roth set up the processed versions of the files and combined the CM and PCS to make the files easier to use.
