October 1st, 2025, came and went, and with it came the annual FY 2026 ICD 10 CM code updates. Hundreds of codes got added, deleted, or changed, and if you’re still billing the way you did earlier, those claims are being rejected.
Some practices adopted these updates easily, but plenty are dealing with claim denials they didn’t expect. The difference usually comes down to knowing what actually changed and acting on it quickly. In this article, we’ll cover every single ICD 10 CM code change for FY 2026. By the end of it, you will know exactly what’s different from last year and what you need to do to keep your revenue stable.
The Centers for Medicare & Medicaid Services (CMS) released the FY 2026 ICD-10-CM updates in June 2025, effective October 1st, 2025, onwards. Here’s what changed:
