ICD-10-CM Changes for FY2026
The FY2026 ICD-10-CM update, effective October 1, 2025, added 383 codes (333 billable), deleted 0, and subdivided 20 previously billable codes into 79 more specific replacement codes. Notable changes include the subdivision of G35 (multiple sclerosis) by disease course, E78.01 (familial hypercholesterolemia) by zygosity, and R10.2 (pelvic and perineal pain) by laterality. Codes that became non-billable can no longer be used for claims with dates of service on or after October 1, 2025.
Also see the upcoming FY2027 ICD-10-CM changes, effective October 1, 2026.

Subdivided Codes: Billable in 2025, Non-Billable in 2026
These 20 codes were billable in FY2025 but are now non-billable parent codes. Claims must use one of the new, more specific replacement codes listed below.
| Old Code (non-billable in 2026) | Replacement Codes (billable) |
|---|---|
| B88.0 Other acariasis | |
| D71 Functional disorders of polymorphonuclear neutrophils | |
| E72.53 Primary hyperoxaluria | |

Deleted Codes
No ICD-10-CM codes were removed from the code set entirely in FY2026. The 20 codes listed above still exist as non-billable parent categories — they were subdivided rather than deleted, so code lookups continue to resolve while billing requires the new, more specific codes.
