For many speech-language pathology practices, the most consequential part of the 2027 CPT change is not the number of new codes. It is the shift from one broad, untimed individual-treatment code to a family that is built around direct one-on-one treatment time.
CPT 92507 remains in effect through December 31, 2026. Beginning January 1, 2027, individual SLP treatment is reported through five clinical code pairs. Each pair has a base code for the initial 30 minutes and an add-on code for each additional 15 minutes (American Speech-Language-Hearing Association [ASHA], n.d.-a).
That changes how a routine session becomes a claim.
The timing thresholds
ASHA’s implementation guidance summarizes the general CPT minimum-time thresholds this way:
• 16–37 minutes: report the applicable base code once.
• 38–52 minutes: report the base code plus one corresponding 15-minute add-on unit.
• 53–67 minutes: report the base code plus two add-on units.
• 68–82 minutes: report the base code plus three add-on units.
Additional qualifying time continues through the corresponding add-on code, subject to CPT instructions and payer policy (ASHA, n.d.-a; ASHA, n.d.-b).
The code family still depends on the clinical service. Time determines the unit structure after the correct service category is selected.
What a 30-minute session looks like
A 30-minute speech-sound production visit would generally use 92656 once.
A 30-minute language treatment visit would generally use 92658 once.
A 30-minute combined speech-sound and language visit would generally use 92660 once.
The key is that the practice does not select a code based on duration alone. A 30-minute visit is not a single universal SLP service anymore. The clinical category and direct treatment time both matter.
What a 45-minute session looks like
A 45-minute language visit would generally be reported as 92658 plus one unit of +92659.
A 45-minute fluency visit would generally be 92654 plus one unit of +92655.
A 45-minute combined speech-and-language visit would generally be 92660 plus one unit of +92661.
The operational problem appears when the practice has one generic 45-minute “speech therapy” service in the EHR. That service label may no longer carry enough information to produce a clean 2027 claim.
What a 60-minute session looks like
A 60-minute speech-sound production visit would generally be 92656 plus two units of +92657.
A 60-minute combined speech-and-language visit would generally be 92660 plus two units of +92661.
That structure is materially different from billing one 92507 regardless of whether the clinician spent 30, 45, or 60 minutes in individual treatment.
Why this can affect expected reimbursement
Under the new structure, longer qualifying sessions may generate additional add-on units. CMS has proposed Medicare relative values and payment amounts for the new codes, but the 2027 Medicare Physician Fee Schedule is still in proposed-rule status as of this writing (CMS, 2026). Commercial plans, Medicaid programs, managed care plans, and other payers establish their own reimbursement and implementation rules (ASHA, 2026).
That means a practice can model the operational effect of timed coding now, but it should not assume that a Medicare benchmark equals its contracted payer rate.
The billing team needs three separate pieces of information:
1. What clinical treatment family applies?
2. How many qualifying direct one-on-one minutes were delivered?
3. What does the specific payer allow for that code, unit count, authorization, modifier, and place of service?
No double-counting
The same treatment minutes cannot be used to support two timed services.
If a separate CPT service is reported on the same date, the service must independently meet its own coding requirements. Where time is relevant, the practice must be able to distinguish the time supporting each service. NCCI edits, payer rules, authorization limits, and modifier requirements still need to be checked.
This is especially important for practices that have historically used multiple service lines during the same encounter or relied on a billing team to infer what happened from a narrative note.
What this changes in scheduling
The schedule itself does not have to become a coding system, but recurring appointment templates should make the downstream service easy to identify.
A practice may need separate service choices for:
• 30-minute speech sound production
• 45-minute speech sound production
• 60-minute speech sound production
• 30-minute language treatment
• 45-minute language treatment
• 60-minute language treatment
• combined speech and language sessions
• fluency
• voice/resonance/upper-airway treatment
The exact EHR design can vary. The control should remain the same: the clinician must be able to select the service actually delivered, and the documented direct time must support the units billed.
The revenue-protection control
Before January 1, run a sample of your most common session lengths through the new code families.
Take your actual 30-, 45-, and 60-minute services. Map each one to the likely clinical category. Confirm what documentation supports it. Then identify what has to change in scheduling, charge entry, authorization tracking, claim review, and staff training.
That exercise will expose the workflow gaps before they become 2027 denials.
TECHNOLOGY SPOTLIGHT — SIMPLEPRACTICE INSURANCE NAVIGATOR
The 2027 SLP transition will put more pressure on front-end insurance verification, authorization tracking, clean claim setup, and fast resolution when a payer rejects or denies a new code combination. Behavioral Billing is currently evaluating SimplePractice’s new Insurance Navigator workflow in live revenue-cycle operations for exactly those kinds of tasks.
Insurance Navigator is scheduled to become available as an optional SimplePractice insurance upgrade beginning October 1, 2026. It includes the existing Insurance Essentials tools plus automated verification of mental-health benefits and estimated client responsibility, Claim Assistant guidance for common rejections and denials, payment autofill from uploaded EOBs, personalized insurance onboarding, and direct phone access to SimplePractice Insurance Specialists for payer setup, claim issues, enrollments, payer requirements, and payment reconciliation (SimplePractice, 2026a).
For practices already reviewing their EHR and billing workflow ahead of January 2027, this is a useful time to evaluate whether those tools can remove repetitive insurance work while keeping your internal billing controls intact.

SimplePractice’s Insurance Navigator trial is a separate offer. SimplePractice is currently promoting a 30-day trial for eligible practices before deciding whether to continue with the upgrade. Insurance Navigator is priced by submitted claim rather than as an increase to the monthly SimplePractice subscription; current published pricing is $1.79 per submitted claim, compared with Insurance Essentials starting at $0.39 per submitted claim (SimplePractice, 2026b).
Affiliate disclosure: Behavioral Billing may earn a commission if you sign up for SimplePractice through our partner link, at no additional cost to you. Offers and product pricing are time-sensitive and should be verified at the time of enrollment.
