67 Billing Code Changes Are Coming to Your Dental Practice on January 1
Every fall, the American Dental Association's Code Maintenance Committee finalizes next year's changes to the CDT code set, the codes your practice puts on every claim you submit. For 2027, that's 67 changes: 28 new codes, 33 revisions, and 6 editorial updates, all taking effect January 1. The updated code set becomes available this fall, which means the countdown to a January 1 that either goes smoothly or doesn't has already started.
Most practices treat this like a compliance footnote, something the software vendor handles quietly in the background. It usually isn't. In a lot of offices, nobody owns it, and the first sign anything changed is a stack of denied claims in February.
What's actually changing in CDT 2027
The 67 changes touch several parts of a typical practice's day-to-day coding:
- New implant codes covering healing cap placement, screw-retained restoration removal, and interim fixed dentures.
- New codes for orofacial pain management, including occipital nerve, peripheral nerve, and sphenopalatine ganglion injection blocks, where no dedicated code existed before.
- A revised D2390 (direct resin composite crown) that now applies to posterior teeth as well as anterior, widening how it can be billed.
- Updates to orthodontic attachment codes and administration codes for neuromodulators, now distinguishing cosmetic use from therapeutic use.
None of that is exotic. It's the kind of steady, incremental change the ADA makes most years, which is exactly why it's easy to underestimate.
Why a code you never touch still costs you
The risk isn't really the 28 new codes. Practices tend to notice new codes because a doctor asks how to bill a new procedure. The risk is the codes that get revised or retired quietly underneath the ones your team already uses on autopilot.
A dental-focused accounting firm put it plainly in its own rundown of last year's CDT update: a deleted code that's still selectable in your practice management software is a "denial magnet." It's only a matter of time before a busy front desk, or a newer team member who's never seen the change list, picks it anyway. The claim doesn't come back with a note explaining what happened. It just comes back denied, and now someone has to figure out why, resubmit, and absorb the delay in getting paid.
Most practice management systems won't remove or update a code on their own. Someone has to run the update, and if the system can't delete a retired code outright, someone has to at least hide it so the front desk can't select it by habit.
A short checklist before January 1
This doesn't take a big project. It takes someone's name on three things, done once, well before the first claim of 2027 goes out:
- Confirm with your practice management vendor when the CDT 2027 update lands in your system, and whether retired codes get removed automatically or need to be hidden manually.
- Pull your practice's ten or so most-used codes and check them against this year's change list. A code you bill every week (like D2390, this year) is worth five minutes of attention.
- Put it on next year's calendar too. This isn't a one-time fix, it's an annual task that needs an owner, the same way you'd assign renewing a license or a certification.
Where this fits with an agent, not instead of one
This is a good example of the kind of task that falls through precisely because it happens once a year and sits outside everyone's daily job. It's exactly what we build agents for: something that reads your practice's actual claim history, cross-checks your most-used codes against the ADA's published change list every fall, and hands your office manager a short, plain-language list of what to review before the update goes live. The agent does the reading and the flagging. Your team still decides what to change and confirms it before anything touches a claim. See more on how that division of labor works on our how it works page, or how we apply it specifically to dental practices. If you'd rather just talk it through, book a 30-minute call.
