15675 searchable codes: 15573 in the ICD-10-CA release, the 74 withdrawn in it, and the crosswalk codes that exist only in ICD-10-CM. Filter by specialty, diagnostic category, body system, coding standard, chapter and reportability. 1569 are linked to a structure in the 3D explorer.

About the facets. Diagnostic category and body system are derived by this service from the published chapter and block structure — C00–D48 is neoplasm wherever it appears, C64–C68 is urinary tract. They are search aids, not CIHI's editorial assignment, and carry no authority for a coding decision. Codes bound to anatomy use their real mapping instead of the derived one.
