Speech Therapy Billing Services
We bill speech-language pathology practices, and SLP needs its own approach because the revenue does not behave like the rest of therapy. Speech and language treatment is untimed: a session is one unit whether the therapist works thirty minutes or a full hour. There is no unit math to get right and no extra units on a longer session, so the whole billable decision is made at the top of the note, when someone decides what the session was. Three of those decisions carry most of the money. The first is the evaluation tier — fluency, speech sound production, the combined sound-production-and-language evaluation, and the voice and resonance analysis are four different codes at four very different rates, and the comprehensive evaluation most pediatric and stroke-recovery cases warrant pays roughly twice what the sound-production evaluation does. Practices that default to one tier across the board hand that difference back on every evaluation their own documentation would have supported at the higher one. The second is swallowing: dysphagia sessions routed to the general speech and language treatment code instead of the swallowing-specific one, and instrumental endoscopic swallow studies billed as though they were bedside clinical evaluations. The third is the Medicare threshold — $2,480 for CY2026, shared with physical therapy under the same beneficiary, so a stroke patient in both disciplines crosses it sooner than either practice tracking alone would predict, and claims past it are denied without the KX attestation. That is the work we take on. We code evaluations to the domain assessed and keep documentation templates that defend a comprehensive evaluation against downcoding. We file the swallowing-specific treatment code where the note supports a swallowing focus, and we code instrumental studies as instrumental studies. We put the discipline modifier on every line, watch combined physical therapy and SLP utilization for each Medicare patient, and apply KX with documentation when the threshold is reached. We classify each pediatric case as habilitative or rehabilitative before treatment starts, because BCBS and several commercial plans meter those two benefit categories separately, and we renew referrals before they lapse — for outpatient SLP practices, pediatric clinics and school-contracted therapists billing Medicare, Medicaid and commercial plans side by side.

How does speech therapy billing work?
We bill speech-language pathology practices end to end — evaluation coding, treatment claims, dysphagia work, referral and authorization tracking, and the A/R behind all of it. What makes SLP different is that treatment is untimed: a session is one unit whether the therapist works thirty minutes or an hour, so revenue turns on which code was chosen, not on how long the visit ran. We file the swallowing-specific treatment code where the session treats swallowing instead of routing everything to the general one, we code instrumental swallow studies as instrumental studies, and we track physical therapy utilization alongside SLP because Medicare counts both against one annual threshold. The amounts in the code table below are CY2026 Medicare national unadjusted non-facility amounts — total non-facility RVUs times the 33.4009 conversion factor in CMS's CY2026 relative value file, October release, read 17 September 2026 — before locality adjustment and nothing to do with commercial rates.
- Evaluation coded to the domain actually assessed, including 92523 where sound production and language comprehension were both evaluated
- 92526 filed for dysphagia treatment rather than routing every swallowing session to 92507
- FEES reported as 92612, the complete endoscopic procedure, or 92613 for interpretation and report only, when an instrumental study replaces the bedside 92610 evaluation
- Pediatric cases classified habilitative or rehabilitative before treatment starts, so the wrong benefit category is not exhausted
- Free billing review before you switch — we tell you which sessions are coded below what your documentation already supports

Common Billing Friction in Speech Therapy
Untimed treatment codes — 92507 vs 92526 and the dysphagia upcharge
SLP treatment codes are untimed: 92507, treatment of speech, language, voice, communication and/or auditory processing disorder, individual, is one unit per session (~$76 at the CY2026 Medicare national non-facility rate); 92508 group treatment for two or more patients (~$24 per patient); 92526, treatment of swallowing dysfunction and/or oral function for feeding, is one unit per session (~$84). Practices that default to 92507 for every patient — including the dysphagia patients receiving swallow strengthening, oral-motor exercises, and diet modification training — give up the 92526 differential on every one of those sessions — $84 against $76 on the CY2026 Medicare national amounts, about $8 a session, and more on commercial fee schedules that price the two codes further apart. Documentation must specify the swallowing focus to support 92526. Unlike PT's 97110 or OT's 97530, which bill in 15-minute units under the 8-Minute Rule, there is no unit-rounding leakage on the SLP treatment side and no way to capture extra units on a longer session.
Evaluation tier selection — 92521 vs 92522 vs 92523 vs 92524
SLP evaluations split by domain: 92521 evaluation of speech fluency (~$133 at the CY2026 Medicare national non-facility rate), 92522 evaluation of speech sound production (~$112), 92523 evaluation of speech sound production WITH evaluation of language comprehension and expression (~$226), 92524 behavioral and qualitative analysis of voice and resonance (~$110). CPT instructs that 92522 and 92523 are not billed together. The combined sound-production-plus-language evaluation (92523) is the appropriate code for most pediatric and stroke-recovery evaluations, and pays substantially more than either single-modality code. Practices that default to 92521 or 92522 across the board give up the difference on every comprehensive evaluation their own documentation would have supported at 92523: $226 less $133, or $226 less $112, is roughly $93 to $115 a case on the CY2026 Medicare national amounts.
Shared $2,480 Medicare threshold with PT — combined cap tracking
Medicare's annual SLP services threshold is $2,480 for CY2026 (the KX modifier threshold amount published by CMS on its Therapy Services page, verified September 17, 2026), shared with physical therapy as a combined PT/SLP threshold under the same beneficiary. A patient receiving both PT for a stroke and SLP for aphasia counts utilization from both disciplines against the same $2,480 — and crosses the threshold faster than either discipline tracking alone would predict. Above the threshold, modifier KX must be applied to attest to medical necessity; without KX, claims are denied. Above $3,000 combined, the patient enters the Targeted Medical Review band where the MAC can audit. Practices without combined PT/SLP tracking absorb cap-cross denials they could have prevented.
FEES — 92612 and 92613 and the dysphagia evaluation upgrade
Fiberoptic Endoscopic Evaluation of Swallowing (FEES) is an instrumental swallowing assessment using a flexible nasendoscope to visualize the pharyngeal phase. The SLP reports 92612 — flexible fiberoptic endoscopic evaluation of swallowing by cine or video recording, which is the complete endoscopic procedure — or 92613 when the SLP did not pass the scope and supplies the interpretation and report only; 92613 is not billed in addition to 92612. 31575 is a diagnostic flexible laryngoscopy, a separate service rather than a required companion line on every FEES claim. FEES reimburses substantially more than a bedside clinical swallow evaluation when an instrumental assessment is medically necessary: on CY2026 Medicare national non-facility amounts from CMS's relative value file, 92612 runs about $200 against about $85 for 92610, evaluation of oral and pharyngeal swallowing function — roughly $115 a case. 92613 runs the other way: interpretation and report only pays about $36, well below the bedside evaluation, so the choice between 92612 and 92613 follows who passed the scope rather than what the claim is worth. Practices with the equipment and training to perform FEES sometimes default to 92610 because the FEES coding is unfamiliar.
Habilitative vs rehabilitative benefit split on pediatric cases
BCBS and several commercial plans apply distinct habilitative versus rehabilitative benefit categories to pediatric SLP cases, with different annual session limits applied to each. Habilitative services help develop a function never acquired (pediatric articulation, expressive language delay, fluency in a child who has not previously achieved fluency). Rehabilitative services restore a function lost to injury or illness (post-stroke aphasia, post-TBI cognitive-communication). Misclassifying the benefit type causes either premature denial when the wrong category is exhausted or missed coverage when the correct category was available.
Speech Therapy-Specific Payer Issues We Watch For
Medicare
Issue: Speech therapy shares the annual threshold with physical therapy ($2,480 combined in CY2026, per CMS) — SLP services that push the patient over the cap require the KX modifier and supporting documentation
Our approach: We monitor combined PT/SLP therapy cap utilization for each Medicare patient and apply the KX modifier with documentation when the threshold is reached
UnitedHealthcare
Issue: Requires a physician referral for speech therapy and denies claims when the referral is not on file or has expired, even for ongoing treatment
Our approach: We track referral expiration dates and request renewals 30 days before expiration to prevent gaps in authorization
BCBS
Issue: Limits speech therapy for pediatric patients to habilitative vs rehabilitative benefits and applies different session limits depending on the classification
Our approach: We verify whether each pediatric case falls under habilitative or rehabilitative benefits and track the correct session limit per benefit category
Cigna
Issue: Does not cover group speech therapy (92508) on many plans and denies claims regardless of the clinical rationale for group treatment
Our approach: We verify group therapy coverage before treatment planning and schedule individual sessions when group therapy is not covered under the patient's Cigna plan
What We Handle
Treatment coding — 92507, 92508, 92526 with dysphagia discipline
Untimed treatment code selection with 92507 for general speech/language, 92508 for group sessions, and 92526 specifically for dysphagia therapy with documentation that supports the swallowing focus. Evaluation and treatment stay distinct: 92610 evaluates oral and pharyngeal swallowing function, 92526 treats swallowing dysfunction and/or oral function for feeding. 92522 is an evaluation of speech sound production and is never a dysphagia-treatment code.
Evaluation tier coding — 92521, 92522, 92523, 92524
Domain-specific evaluation coding with 92523 for combined sound-production-plus-language assessments where pediatric and stroke-recovery cases warrant the higher-tier code, and the documentation templates that defend the comprehensive evaluation against payer downcoding.
Dysphagia evaluation — 92610 bedside vs FEES 92612/92613
Bedside swallow evaluation (92610) coding for clinical assessment, instrumental FEES coding on 92612 for the complete endoscopic procedure or 92613 where the SLP supplies interpretation and report only, and the modified barium swallow study, where 92611 reports the SLP's work during the motion fluoroscopic evaluation and the radiologist separately reports 74230.
GN modifier and KX threshold tracking
GN modifier on every SLP line to identify the discipline, KX modifier application above the $2,480 CY2026 threshold with combined PT/SLP utilization tracking, and pre-emptive review of cases approaching the $3,000 Targeted Medical Review trigger.
Cognitive-communication therapy — TBI and stroke billing
Cognitive-linguistic therapy coding for traumatic brain injury and post-stroke patients with documentation that supports the medical necessity of cognitive-communication treatment, including 97129 and 97130 cognitive-function intervention codes where applicable.
Pediatric SLP — habilitative/rehabilitative benefit and Medicaid
Pediatric case classification between habilitative and rehabilitative benefit categories per payer, school-based SLP under district contracts and IEP-tied billing, and pediatric Medicaid documentation requirements that differ from commercial pediatric plans.

Key Speech Therapy CPT Codes
| CPT Code | Description | Medicare Amount CY2026 national, non-facility |
|---|---|---|
| 92521 | Evaluation of speech fluency | $133 |
| 92522 | Evaluation of speech sound production | $112 |
| 92523 | Evaluation of speech sound production with evaluation of language comprehension and expression | $226 |
| 92610 | Evaluation of oral and pharyngeal swallowing function | $85 |
| 92526 | Treatment of swallowing dysfunction and/or oral function for feeding | $84 |
| 92507 | Treatment of speech, language, voice, communication and/or auditory processing disorder; individual | $76 |
| 92508 | Speech/language treatment, group (2+ patients) | $24 |
| 31575 | Diagnostic laryngoscopy, flexible fiberoptic | $127 |
Amounts are the Medicare national unadjusted non-facility amounts for CY2026, computed from the published CMS relative value file. They are not what a commercial payer pays, and your locality adjustment moves them. A dash means Medicare publishes no amount for that code — because it is non-covered, bundled, or priced outside the fee schedule.
Why General Billing Teams Miss Speech Therapy Issues
General billing staff handle dozens of specialties and rarely develop the depth needed for speech therapy coding nuances. Here is what gets missed.
Modifier and bundling errors
Specialty-specific modifier rules and CCI edits are frequently overlooked by teams that do not work exclusively in speech therapy.
Under-coding high-complexity visits
Speech Therapy encounters often qualify for higher-level E/M codes, but generalist billers default to mid-level codes to avoid audit risk.
Missed payer-specific rules
Each payer has unique coverage and documentation requirements for speech therapy procedures that general teams rarely memorize.
Slow denial turnaround
Without specialty knowledge, appeal letters lack the clinical specificity needed to overturn speech therapy denials quickly.
“Swallowing is where the codes most often go unused. 92610 evaluates oral and pharyngeal swallowing function and 92526 treats swallowing dysfunction; 92507 is the general speech and language treatment code and says nothing about a swallow. How often a practice defaults to the general code on a session its own note describes as swallowing work is the number that matters, and we have not seen a published benchmark for it and do not quote one. Pull one month of your own dysphagia sessions against the code that was billed — it is an afternoon's work, and it is your number rather than an industry one.”

Speech Therapy Billing Terms
- Speech Evaluation Complexity
- Speech-language evaluations are coded by type and complexity: 92521 (evaluation of speech fluency), 92522 (evaluation of speech sound production), 92523 (speech sound production with evaluation of language comprehension and expression), and 92524 (behavioral and qualitative analysis of voice and resonance). Selecting the code that matches the evaluation scope directly affects reimbursement.
- Dysphagia Evaluation (92610)
- A clinical (bedside) evaluation of oral and pharyngeal swallowing function, distinct from the speech-language evaluation codes. The descriptor covers the oral and pharyngeal phases; the esophageal phase is not part of this code. Separately billable from speech treatment services.
- Habilitative vs Rehabilitative
- Habilitative services help develop a function never acquired (common in pediatric speech), while rehabilitative services restore a function lost due to injury or illness. Payers may apply different benefit limits to each category.
- Therapy Cap (SLP)
- Medicare's annual dollar threshold for SLP services, shared with physical therapy. Services above the cap require the KX modifier attesting to medical necessity. SLP and PT utilization both count toward the combined threshold.
- FEES (Fiberoptic Endoscopic Evaluation of Swallowing)
- An instrumental swallowing assessment using a flexible endoscope to visualize the pharyngeal swallow. Reported as 92612, the complete procedure with cine or video recording, or 92613 for interpretation and report only. On CY2026 Medicare national non-facility amounts 92612 pays well above the bedside 92610 evaluation and 92613 pays well below it, so the two FEES codes are not interchangeable.
- Treatment Code Selection (92507 vs 92526)
- 92507 is the general speech/language treatment code, while 92526 is specific to swallowing dysfunction treatment. Coding the session to what was actually treated is the point; on CY2026 Medicare national non-facility amounts 92526 is $84 against 92507's $76.

Request a Specialty Billing Review
See how specialty-specific billing support can improve reimbursement visibility for speech therapy billing services.
Request ReviewHow do you bill for modified barium swallow studies?
MBSS billing uses CPT code 92611 for the SLP component and separate radiology codes for the imaging component. We coordinate with radiology billing to prevent duplicate claims and ensure each provider bills their respective professional component correctly.
Does speech therapy share a therapy cap with physical therapy?
Yes, under Medicare, SLP services share the annual therapy spending threshold with PT services. We track cumulative spending across both disciplines in real time and apply the KX modifier when the combined threshold is exceeded to maintain coverage.
Can you bill for telepractice speech therapy sessions?
Yes. We bill telepractice SLP sessions with appropriate place-of-service codes and telehealth modifiers. Coverage for telepractice SLP varies by state and payer, so we verify coverage for each patient before services begin.
