For as long as most of us have been billing, the articulation therapy CPT code has been the same one: 92507. Artic, phonological process, childhood apraxia, dysarthria, it all went out the door under a single untimed code, one unit per session, no stopwatch required. If you treat speech sound disorders, you could probably key that claim in your sleep.
That changes on January 1, 2027. CPT 92507 is being deleted, and speech sound production treatment gets its own timed code family with a base code and an add-on.1 So the way you report an artic or apraxia session is about to look different, even though the therapy itself stays exactly the same.
Here's what the new codes actually cover, how the timed base-and-add-on math works, the combined-session trap that's going to trip people up, and what to document now so the switch is a non-event.
The One Code That Now Covers Articulation, Phonological, Apraxia, and Dysarthria
Start with the good news: you don't have to memorize a separate code for each speech sound diagnosis. ASHA has published the structure, and articulation, phonological process, apraxia, and dysarthria all live in one family.2 The base code descriptor reads "Treatment of speech sound production disorder (eg, articulation, phonological process, apraxia, dysarthria), direct (one-on-one) patient contact; initial 30 minutes," with an add-on code for each additional 15 minutes.2
So four diagnoses you tend to think of as distinct share the same code pair. Apraxia treatment billing and phonological disorder coding aren't off in their own corners of the code book. They report through the same base and add-on you'd use for a straightforward /r/ kid.
Now the honest part. ASHA is using placeholder designations for these, base 92X2X and add-on +92X3X, because the real five-digit numbers don't exist yet.2 The AMA assigns them when the 2027 CPT code set publishes, expected in September or October 2026.1 What's confirmed today is the structure, not the digits: a base code for the initial 30 minutes, an add-on for each additional 15. That's the piece you can plan around right now.
One scope note so nobody mixes wires. This is treatment only. Your speech sound production evaluation code, 92522, is a separate animal and isn't part of this change.
From Untimed to Timed: The New Base-and-Add-On Math
This is the shift that actually changes your workflow. Under 92507, session length didn't matter for billing. A 25-minute artic session and a 55-minute one billed the same single unit, because untimed codes are reported once per day regardless of time.3 With the new codes, time becomes part of what you report.
ASHA has spelled out the thresholds. You'll need 16 to 37 minutes to report one unit of the base code, and 8 to 22 minutes to report the add-on after the base period is done.2 Put plainly, a speech sound session has to reach at least 16 minutes before its base code is billable at all.
That's a real break from how a dysarthria CPT code claim works today, where the clock never entered into it. If you're the one running claims, the muscle memory of keying one unit per visit has to give way to a quick minute check on every session. It sounds small. It's the single biggest day-to-day change in the whole transition.
A Worked Example: Billing a 45-Minute Apraxia Session
Numbers make this concrete, so let's walk one. Say you see a child for 45 minutes of one-on-one apraxia treatment.
The base code covers the initial 30 minutes. That leaves 15 minutes, which sits comfortably inside the 8-to-22-minute add-on window, so you report one add-on.2 Your claim is one base plus one add-on. Simple enough once you've done it a few times.
Two quick contrasts to lock it in. A 20-minute articulation session clears the 16-minute floor, so you bill the base, but there aren't enough extra minutes for an add-on, so that's all you report. And a 12-minute session? That falls below the 16-minute threshold, so the base isn't billable.2 Under 92507, that short session would have quietly earned one clean unit. Under the new codes, it doesn't.
Push the session a little longer and the pattern holds. A 50-minute dysarthria session with an adult stroke patient is 30 minutes of base plus 20 more, and 20 sits right in the 8-to-22-minute add-on window, so you're back to one base plus one add-on.2 The number that drives all of this is your actual skilled, one-on-one treatment time, not the length of the appointment on the schedule.3 If a 45-minute slot includes five minutes of a child settling in and a hand-off at the door, those minutes aren't treatment, and they don't count toward your base or your add-on.
This is the math your front desk or billing staff will run on every single visit. It's also exactly why capturing treatment time stops being a nice-to-have and becomes the thing your claim rides on.
The Combined Speech Sound and Language Trap
Here's the one I'd circle in red. Plenty of pediatric sessions aren't pure artic. You spend part of the visit on /s/ blends and part of it building sentences, mixing a speech sound goal and a language goal in the same block. Very common, very reasonable therapy.
But you can't bill it by stacking the speech sound base code and a separate language base code. When you treat speech sound production and language together in one session, ASHA directs you to a dedicated combined code family (placeholder 92X6X and its add-on) instead of reporting the two areas separately.2 There's a purpose-built code for exactly this pairing.
Why does it matter enough to flag now? Because reporting two base codes for one combined session is the kind of predictable error that generates a denial. The habit you want is already knowing which sessions are "combined" and reaching for the combined code, not two separate ones. It all ties back to the bigger picture: CPT 92507 is being deleted in 2027 and replaced by ten new timed codes across five disorder areas, and the combined code is one of those five.
Documentation That Defends Both Minutes and Medical Necessity
Timed codes raise the stakes on your notes, and in two directions at once. Your documentation now has to support the treatment time you reported and show that the service was skilled and medically necessary.3 The minutes and the medical necessity both have to be defensible, because payers can, and do, look at either one.
Speech sound work draws its share of scrutiny, apraxia and dysarthria especially. The language that protects an apraxia claim is skilled-service language: the cueing hierarchy you used, the motor-planning targets, the intelligibility measures you tracked session to session. That's what tells an auditor a licensed clinician was doing something only a licensed clinician can do, not running through flashcards.
It helps to picture what "skilled" looks like on the page. "Practiced /k/ words for 20 minutes" reads like something a parent could run at the kitchen table. "Elicited /k/ in final position with tactile placement cues, faded to verbal models, and tracked production at 80% accuracy across three contexts" reads like clinical judgment only you can provide, and it defends the minutes and the medical necessity in one shot.5 For Medicare patients, the plan of care carries a lot of this weight too. If you write it rather than the physician, it has to be certified by the physician within 30 days, recertified at least every 90 days, and backed by a progress report at least every 10 treatment days.6 None of that is new for 2027, but timed codes shine a brighter light on all of it.
So what do you actually do between now and 2027? Tighten up your medical-necessity and skilled-service phrasing now, while the pressure is low, and get comfortable naming both the disorder area and the minutes in every note. And keep billing 92507 correctly for individual treatment right through the end of 2026, because nothing changes until the switch.4
If you supervise students in a university clinic, this is a gift, honestly. The cohort you train in the fall of 2026 graduates straight into timed billing. Teaching them to document treatment time and skilled service from their very first note means they never have to unlearn the old untimed habits the rest of us do. This is also where a time-stamped EMR earns its keep: SOAP notes that capture minutes automatically, templates you can build around each disorder area, and reporting that flags a documentation gap before it becomes a denial.
What the Switch Changes in Your Clinic's Workflow
Most of the real friction won't be clinical, it'll be operational. Scheduling is the first piece. If your day is built around loose 30- or 45-minute blocks, start thinking in terms of the treatment minutes you'll actually deliver and document, because that's what the base and the add-on ride on. A slot that reliably runs 28 minutes of hands-on time is a base-only visit, and knowing that in advance helps you build a caseload that bills the way you expect.
Your front-desk and billing staff need a heads-up too, because the person keying claims can no longer assume one visit equals one unit. They'll be reading a minute count off your note and turning it into a base plus any add-ons, so the note has to hand them that number cleanly. The cheapest fix is a dry run in 2026: keep billing 92507 as usual, but record treatment minutes alongside it, so clinicians and billers get the reps before the codes go live.
Start the Habits Now
The short version: articulation, phonological, apraxia, and dysarthria treatment all consolidate into one timed speech sound production code family in 2027, the real code numbers land in the fall of 2026, and the two things worth learning early are the base-and-add-on math and the combined-code rule. None of it requires the final digits to get ready, and the habits pay off no matter what system you use. Accurate minutes and clean skilled-service language make your claims more defensible today and ready for the articulation therapy CPT code changes tomorrow.
