ICD-10 code equivalency mappings

To help you navigate the codes used in provider guides, we made program-specific crosswalks of ICD-9 to ICD-10 codes. This is not a comprehensive equivalency mapping of all ICD-9 and ICD-10 codes. These are policy-specific mappings within specific programs.

Note: Not all of the Washington Apple Health programs (mappings) are listed on this page. If the program you are looking for is not listed here, you can find the ICD-9 to ICD-10 mappings listed in the program-specific provider guide. Refer to the hospital or professional provider billing guides page for a full list of programs.
