FY 2026 Revised Codes FAQ
How many ICD-10-CM codes were revised for FY 2026?
The FY 2026 release revises the descriptions of 38 diagnosis codes across 7 chapters, with most revisions in Injury, poisoning and certain other consequences of external causes (S00–T88) (24 codes).
What changes when a code is revised?
Only the official description changes. The code itself stays valid and billable, so no remapping is needed, but encounter forms, cheat sheets, and EHR favorites should show the updated wording to avoid documentation mismatches.
When do the FY 2026 codes take effect?
The FY 2026 code set applies to dates of service from October 1, 2025 to September 30, 2026. ICD-10-CM follows the federal fiscal year, so the update takes effect on October 1, not January 1.
All counts and code lists on this page come directly from the official FY 2026 ICD-10-CM release files published by CMS and the National Center for Health Statistics (NCHS).
