#cdtcode

Every year, the ADA CDT update gets released, and most dental teams skim it for new codes. That’s the wrong place to focus. The real operational risk in CDT 2026 sits with the deleted codes. Codes that no longer exist, but still live inside fee schedules, templates, auto-posting rules, and staff habits. These are the codes that quietly break claims, slow payments, and inflate A/R without anyone noticing until cash flow tightens.

This article focuses on the CDT codes deleted in 2026, what their removal means in real billing terms, and how dental practices should respond from a dental revenue cycle management perspective, not just a coding checklist.
