Annual CPT, HCPCS, and ICD-10 code changes reshape 2026 medical coding landscape

The 2026 updates to CPT, HCPCS, and ICD-10 codes are now public. These revisions include new evaluation and management code structures, revised telehealth modifiers, and additions for novel drug administration and diagnostic tests. Every payer will adopt these code sets for claims with dates of service on or after January 1, 2026. Your coding team must review the final code lists and update your charge master, billing software, and encounter forms by Q4 2025. Failure to implement these changes will cause claim rejections and payment delays starting January 1.
