If you're a pediatric SLP, the part of the 92507 change that matters most for your daily life is the time math.
The new codes that take effect January 1, 2027 are timed. That means how long you spend on each disorder area, in each session, suddenly determines how many units you can bill. PT and OT have lived with this for years. SLP hasn't. And pediatric sessions tend to be shorter than adult outpatient sessions, which means pediatric clinicians are going to feel this transition more than anyone else.
This post walks through the actual math. Every common pediatric scenario, every session length, what you'd bill under 92507 today, and what you'd bill under the new structure starting January 2027.
The AMA released the CPT 2027 code set on September 9, 2026. The ten new codes are 92654 through 92663, and the scenarios below now use the real numbers.
Code numbers are as published by the Louisiana Speech-Language-Hearing Association from the CPT 2027 code set. ASHA has not yet posted its own public crosswalk, so verify against the CPT 2027 codebook or data file before configuring billing systems. Medicare payment amounts are still pending the CMS final rule in November 2026.
The rule, in one sentence
To bill the base code, you need at least 16 minutes of treatment on a single disorder area. To add a 15-minute add-on unit, you need to complete the full 30-minute base period plus at least 8 more minutes.
That's it. The rest is application.
Where these numbers come from
The base codes for the new SLP timed structure cover an initial 30-minute interval. CPT uses a midpoint convention for timed codes, which means you must spend more than half of the designated time before the code becomes billable. Half of 30 is 15, so the threshold is 16 minutes for the base code.
The add-on codes are 15-minute increments. The midpoint rule applied to a 15-minute unit gives you the 8-minute threshold. This is the same "8-minute rule" that PT and OT have used for years, applied to the new SLP add-ons. CPT instructions, CMS rules, and individual payer policies can all set different requirements, so confirm each payer's policy before you report.
The unit ladder
Here's the table you'll memorize within a week of January 1, 2027:
Note that the second row is wider than the rest. Anything between 16 and 37 minutes on a single disorder area gets you the same one unit. That's the band where most pediatric sessions live.
Fluency is 92654 and 92655. Speech sound production is 92656 and 92657. Language comprehension and expression is 92658 and 92659. Combined speech sound production and language is 92660 and 92661. Voice with upper airway dysfunction and resonance is 92662 and 92663. In each pair, the first number is the 30-minute base and the second is the 15-minute add-on.
Speech sound production and language are the one pairing you cannot bill as two separate codes. When a session treats both, CPT instructions require 92660 and 92661, and explicitly bar reporting 92656 and 92657 alongside 92658 and 92659. For pediatric caseloads, this is the single most common session type, so it changes the math below.
Common pediatric scenarios, walked through
Let's get specific. Here's how the math plays out for the kinds of sessions pediatric SLPs actually run.
You see a 5-year-old for /r/ articulation. The session runs 25 minutes from start to finish, all spent on speech sound production work.
Today (92507): 1 unit, billed once for the session.
2027 (new structure): 1 unit of 92656, the speech sound production base code. 25 minutes is above the 16-minute threshold but below the 38-minute threshold for an add-on.
You see a child late in the day. The session was scheduled for 30 minutes, but the child needed 10 minutes of regulation support and then was ready for 14 minutes of fluency-focused work before fatigue set in.
Today (92507): 1 unit. The session happened, the work was skilled, you bill once.
2027 (new structure): 0 units billable. 14 minutes is below the 16-minute threshold for 92654.
You see a 7-year-old with developmental language disorder. The full 45 minutes is spent on receptive and expressive language work.
Today (92507): 1 unit.
2027 (new structure): 2 units. 92658 as the base code plus one unit of 92659. 45 minutes is above the 38-minute threshold for the first add-on.
A 6-year-old with both a language delay and a fluency disorder. You spend 25 minutes on language work and 20 minutes on fluency work in the same session.
Today (92507): 1 unit. The single code covers everything.
2027 (new structure): 2 base codes. 1 unit of 92658 (language) for the 25 minutes, 1 unit of 92654 (fluency) for the 20 minutes. Both are above the 16-minute threshold, and language and fluency are separate categories that may be reported together when each is distinct and independently meets its time requirement.
Same patient, same goals as Scenario D, but the session is shorter and time gets split evenly.
Today (92507): 1 unit.
2027 (new structure): 0 units billable. Neither disorder area hits the 16-minute threshold.
A medically complex 4-year-old. You spend 35 minutes on speech sound production and 25 minutes on language.
Today (92507): 1 unit.
2027 (new structure): This is a combined-code session, not two separate codes. Because the session treats both speech sound production and language, you report 92660 for the initial 30 minutes plus 92661 add-ons based on total combined treatment time. At 60 minutes, that is 92660 plus two units of 92661. Reporting 92656 and 92658 separately here would be a coding error.
The new codes don't reward longer sessions per se. They reward sessions where you spent enough time on a single disorder area to cross a threshold.
What this means for how you structure pediatric sessions
The takeaways from running these scenarios across hundreds of caseloads:
1. The 16-minute threshold is the hill to defend
Most pediatric session billing under the new structure depends on whether you cleared 16 minutes of focused, skilled work on a defined disorder area. Below that, you bill nothing for that disorder area. Above that, you bill the base code.
Practically: when a session has rough patches (regulation issues, short attention span, transitions), the calculation isn't "did the session happen?" It's "did I get 16 clean minutes on the targeted disorder?" Your documentation needs to make that visible.
2. Know which pairings combine and which stay separate
Speech sound production plus language is a combined code, 92660. Everything else that legitimately co-occurs, like language plus fluency or speech plus voice, can be reported as separate codes when each is distinct, medically necessary, and independently meets its own time threshold.
What the structure punishes: the well-intentioned "I'll touch on a few things this session" model where time gets sprinkled across multiple disorder areas without any one getting 16 minutes.
3. Documentation has to track time per disorder area
Your session note needs to show, for each code you bill: start time, end time, total minutes, and what skilled intervention you provided in those minutes. This is closer to PT and OT documentation than to traditional SLP documentation. The same minutes can never be counted toward more than one code.
If your current note template just says "Session focused on speech sound production and language goals," you're not going to pass a 2027 audit. The note needs to reflect "Speech sound production: 22 minutes (initial /s/ blends in CV structures, 80% accuracy with verbal model). Language: 18 minutes (story retell with picture supports, targeting past tense)."
Regulation work, sensory breaks, and transitions are part of pediatric sessions. They're clinically necessary. But they don't count toward the time you bill on a disorder-specific code. Document them, but don't include them in the minute count for billing.
This is one of the trickiest pieces for pediatric clinicians, because the line between "warming up the child" and "skilled intervention" can be genuinely fuzzy. ASHA will likely publish more specific guidance on this before the effective date.
Three things you can do right now
You don't have to wait until January 2027 to get ahead of this.
- Audit your typical session lengths. Pull six months of session notes. Look at scheduled duration, actual face-to-face time, and how time was distributed across disorder areas. Identify which sessions would fall below the 16-minute threshold under the new structure. That's your exposure.
- Practice timed documentation. Even while you're still billing 92507, start documenting time spent per disorder area in your session notes. By the time the new codes go live, you'll have months of practice and a clear sense of your own session distribution.
- Talk to your scheduling team. If you're routinely scheduling 25-minute sessions, model what 30-minute or 35-minute sessions would do to your unit counts. Sometimes the answer is to extend session length. Sometimes it's to be more focused within the existing session length. Both are reasonable. The math tells you which.
The bigger picture
The shift to timed codes is genuinely difficult for pediatric SLPs. Pediatric sessions are shorter on average, have more regulation overhead, and often bounce across disorder areas as a child's attention shifts. The new structure was designed around adult outpatient norms, and it shows.
But it's also true that this is the structure OT and PT have lived with for years, and the world hasn't ended for those professions. What it requires is documentation discipline, intentional session structure, and infrastructure that can handle timed-code complexity at the billing level.
This kind of operational lift is exactly the wall that pushes solo and small-practice pediatric SLPs into burnout. Joining a group practice that handles billing infrastructure, training, and compliance is a legitimate option. Coral Care delivers pediatric care in person across nine states, and we built our billing systems for exactly this kind of complexity. Worth knowing it exists.
The clinicians who do best in 2027 will be the ones who treat this as a documentation discipline question, not a billing question. The discipline part is what carries through. The billing math is the easy part once the discipline is in place.
