The CDT 2026 update — the American Dental Association's annual procedure code revision — became effective January 1, 2026. It introduces new codes for digital workflow procedures, AI-assisted diagnostics, and updated descriptors for existing procedures. Cloud-based dental practice management software updated automatically; desktop systems required manual patches.
If you're a US dental practice (or one billing US insurance), this guide explains exactly what changed in CDT 2026, how to verify your software is current, and what to do if you're still running pre-2026 codes.
CDT (Current Dental Terminology) is the standard procedure coding system maintained by the American Dental Association. Every US dental insurance claim uses CDT codes; non-current codes get rejected. The ADA updates CDT every year, with revisions effective January 1.
The 2026 revision focuses on three areas:
Digital workflow codes — New codes for intraoral scans, 3D printing, CAD/CAM same-day restorations, and digital impressions. These reflect the rapid adoption of digital dentistry since 2020.
AI-assisted diagnostic codes — New codes for AI image analysis, automated periodontal charting, and AI-flagged caries detection. The AI segment grew 78% in 2025.
Updated descriptors — Roughly 50 existing codes received clarified language to reduce claim disputes. Endodontic and implant codes are most affected.
If you use cloud-based dental software (DentinCloud, Curve Dental, Carestack, Denticon, Tab32, Dentrix Ascend), the update happened automatically. No action needed.
If you use desktop software (legacy Dentrix, Eaglesoft, Open Dental on-premise), check:
Software version — Open Dental needs version 23.4 or later; Dentrix needs G7.6 patch; Eaglesoft needs the January 2026 update
CDT code library — Run a test claim against a 2026-only code (e.g., one of the new digital scanning codes) and verify acceptance
Vendor support documentation — Each major vendor published a CDT 2026 readiness checklist in December 2025
If your claims are getting rejected with "invalid code" errors after January 1, you're not on CDT 2026.
Stop using affected codes immediately to prevent claim denials
Contact your software vendor for the CDT 2026 patch
If on legacy desktop, this is a strong signal to evaluate cloud alternatives — cloud platforms updated overnight without effort
Cloud platforms: DentinCloud, Curve Dental, Carestack, Tab32, Dentrix Ascend, Denticon.
CDT updates happen every January. If 2026 caught you off guard, 2027 will too. The simplest defence is moving to a platform that handles updates automatically.
DentinCloud handles CDT updates automatically — patches go live overnight, no clinic intervention required. Free up to 250 patients, no credit card.
