Speech therapy billing and coding trips up a lot of practices. The codes are specific and the rules shift every year. One small mistake, a missing modifier, a mismatched diagnosis code, a timing error, can hold up payment for weeks or kill a claim entirely.
This guide covers speech therapy CPT codes cheat sheet for 2026. We’ve included everything speech-language pathology (SLP) providers need to know about CPT codes in 2026.
We covered evaluations, treatment, swallowing, cognitive therapy, AAC devices, caregiver training, telehealth, modifiers, ICD-10 codes, and documentation.
And if your speech therapy coding workflow is creating more problems than it should, our team at Connecticut MedBill offers free consultation for your practice.
What Are Speech Therapy CPT Codes?
CPT stands for Current Procedural Terminology. These are five-digit codes that describe the services a provider performed during a patient visit. The American Medical Association maintains and updates them each year, effective January 1.
Insurance companies like Medicare, Medicaid, and commercial payers, use CPT codes to process and reimburse claims. Without the correct code, the claim either gets denied or pays the wrong amount.
Speech-language pathology CPT codes appear primarily in the 92000 series, with additional codes in the 96000 and 97000 series. SLPs also use specific HCPCS codes for Medicare services.
What are CPT codes by the way: CPT codes describe what was done. ICD-10 codes describe why it was done. Both must appear on every claim, and they must match.
Speech Therapy Evaluation CPT Codes List for 2026
Speech therapy evaluation CPT codes are used for new patient assessments and formal re-evaluations. They are untimed, but billed once per session regardless of how long the evaluation takes.
Primary Evaluation Codes (92521–92524)
| CPT Code | Description |
| 92521 | Evaluation of speech fluency (e.g., stuttering, cluttering) |
| 92522 | Evaluation of speech sound production (e.g., articulation, phonological process, apraxia, dysarthria) |
| 92523 | Speech sound production evaluation with language comprehension and expression |
| 92524 | Behavioral and qualitative analysis of voice and resonance |
These four CPT codes have been in use since January 2014. CCI edits do not restrict billing them together when separate. Distinct evaluations are performed on the same day, but documentation must clearly reflect each one as a complete evaluation, not a screening.
One important note on 92522 vs. 92523:
You cannot bill both CPT codes 92522 and 92523 on the same day. CPT 92522 is already included in 92523. If a language-only evaluation is performed, use 92523 with modifier -52 to indicate a reduced service.
Additional Evaluation CPT Codes
| CPT Code | Description |
| 96105 | Assessment of aphasia, per hour |
| 96112 | Developmental test administration, first hour |
| 96113 | Developmental test administration, each additional 30 minutes |
| 96125 | Standardized cognitive performance testing, per hour |
| 92610 | Evaluation of oral and pharyngeal swallowing function |
| 92605 | Evaluation for non-speech-generating AAC device, first hour |
| 92618 | Non-speech-generating AAC device evaluation, each additional 30 minutes |
| 92607 | Evaluation for speech-generating AAC device, first hour |
| 92608 | Speech-generating AAC device evaluation, each additional 30 minutes |
| 92597 | Evaluation for use of voice prosthetic device |
Speech Therapy Treatment CPT Codes List
Treatment CPT codes are billed after the initial evaluation during active therapy sessions.
Core Treatment Codes
| CPT Code | Description |
| 92507 | Individual treatment for speech, language, voice, communication, or auditory processing disorder |
| 92508 | Group treatment (two or more patients) for the same disorders |
| 92526 | Treatment of swallowing dysfunction or oral feeding disorder |
92507 is the most commonly billed code in all of speech-language pathology. It is an untimed, service-based code. One unit is billed per treatment day in most cases. The one exception is a BID (twice daily) treatment order, where two units may be billed.
92526 is also untimed and service-based. It cannot be billed as an evaluation, only as a treatment. It can be billed on the same day as a dysphagia evaluation (92610) when the evaluation and the treatment are separate, distinct services with separate documentation.
Swallowing and Dysphagia CPT Codes List
| CPT Code | Description |
| 92610 | Evaluation of oral and pharyngeal swallowing function |
| 92611 | Motion fluoroscopic evaluation of swallowing (VFSS) |
| 92612 | Flexible fiberoptic endoscopic evaluation of swallowing (FEES) |
| 92526 | Treatment of swallowing dysfunction or oral feeding |
Dysphagia billing is an area where documentation errors are especially common. Each claim must be supported by a documented plan of care, and the treatment session must address goals within that plan.
AAC Device CPT Codes List
Augmentative and alternative communication device billing involves both evaluations and ongoing therapeutic services.
Non-Speech-Generating Devices
| CPT Code | Description |
| 92605 | Evaluation for non-speech-generating AAC device, first hour |
| 92618 | Add-on: each additional 30 minutes (use with 92605) |
| 92606 | Therapeutic services for non-speech-generating device |
Speech-Generating Devices
| CPT Code | Description |
| 92607 | Evaluation for speech-generating device, first hour |
| 92608 | Add-on: each additional 30 minutes (use with 92607) |
| 92609 | Therapeutic services for speech-generating device |
Per CMS guidance, 92607 is used for selection and prescription of a speech-generating device. 92609 is used for adaptation and training. These should not be used interchangeably.
Cognitive Therapy CPT Codes for SLPs
Speech-language pathologists frequently treat cognitive-linguistic disorders, including those related to TBI, stroke, dementia, and neurodegenerative conditions.
| CPT Code | Description |
| 97129 | Cognitive function intervention, direct patient contact, initial 15 minutes |
| 97130 | Cognitive function intervention, each additional 15 minutes |
These are timed codes. 97130 is an add-on code and must always be billed with 97129. CMS has noted that these codes do not have diagnosis code limitations, which gives SLPs some billing flexibility.
Note on 92507 and 97129 together: These cannot be billed on the same day by the same provider (92507 is considered inclusive of cognitive-linguistic treatment). However, an OT billing 97129 and an SLP billing 92507 on the same day for different services is permitted.
Caregiver Training CPT Codes List
These codes allow SLPs to bill for training caregivers without the patient present.
Caregiver Training CPT Codes
| CPT Code | Description |
| 97550 | Caregiver training, individual, initial 30 minutes |
| 97551 | Caregiver training, individual, each additional 15 minutes |
| 97552 | Group caregiver training |
Caregiver Training Medicare G-Codes
| HCPCS Code | Description |
| G0541 | Caregiver training, individual, initial 30 minutes |
| G0542 | Caregiver training, individual, each additional 15 minutes |
| G0543 | Group caregiver training |
These G-codes and the CPT codes above look similar but are distinct. The 97550 series applies broadly to facilitating patient function in home or community settings.
The G0541 series applies specifically to direct care strategies for patients with ongoing conditions. When billing Medicare, use the G-codes.
Telehealth Speech Therapy CPT Codes List
Telehealth coverage for SLPs expanded significantly during and after the pandemic. Many private payers now cover remote services as a standard benefit, though policies still vary by plan and state.
2025–2026 Telehealth E/M Codes
| CPT Range | Description |
| 98008–98015 | Telehealth evaluation and management (replaced 99441–99443 for audio-only and audio-video services) |
For treatment codes (like 92507 or 92526), the same CPT code is used and telehealth delivery is identified through modifiers.
Key Telehealth Modifiers
| Modifier | Meaning |
| 95 | Synchronous telehealth (audio and video) |
| GT | Interactive audio-video telehealth (Medicare) |
| GN | Services under a speech-language pathology plan of care |
Always confirm the patient’s payer telehealth policy before billing. Some Medicaid programs have their own telehealth billing requirements separate from Medicare.
Timed vs. Untimed Speech-Language Pathology CPT Codes
SLP providers must understand distinction between timed and untimed CPT codes for it affects how many units you bill per session.
Untimed Codes (Bill Once Per Session)
| CPT Code | Notes |
| 92507 | One unit per treatment day (typically) |
| 92521 | One unit per evaluation |
| 92522 | One unit per evaluation |
| 92523 | One unit per evaluation |
| 92524 | One unit per evaluation |
| 92526 | One unit per treatment day |
| 92610 | One unit per evaluation |
Timed Codes (Units Based on Time)
| CPT Code | Notes |
| 97129 | Initial 15 minutes |
| 97130 | Each additional 15 minutes |
| 96105 | Billed per hour |
| 96125 | Billed per hour |
| 92607 | First hour |
| 92608 | Each additional 30 minutes |
The 8-Minute Rule (Medicare)
For timed codes billed to Medicare and most Medicare Advantage plans:
| Minutes of Service | Units to Bill |
| 8–22 minutes | 1 unit |
| 23–37 minutes | 2 units |
| 38–52 minutes | 3 units |
| 53–67 minutes | 4 units |
Private payers may follow AMA guidelines instead, which calculate units differently. Know which rule applies to each payer you contract with.
CPT Code Modifiers Used in Speech Therapy Billing and Coding
Modifiers tell payers that something about the service was different from the standard description. They do not change the code, they add context.
| Modifier | When to Use |
| GN | Services provided under an SLP plan of care (Medicare) |
| KX | Services exceed therapy cap but are medically necessary |
| 59 | Distinct procedural service (use with caution, only per payer instruction) |
| 52 | Reduced service (e.g., language-only evaluation using 92523) |
| 22 | Service significantly more complex than typical |
| 95 | Synchronous telehealth |
| GT | Interactive audio-video telehealth |
Modifier 59 is one of the most commonly misused codes in all of therapy billing. It should only be applied when no other modifier accurately describes the relationship between two procedures, and only when payer instructions direct you to use it.
Common ICD-10 Codes Used in Speech Therapy
Every CPT code on a claim must be linked to a supporting ICD-10 diagnosis code. The diagnosis must establish medical necessity.
Speech and Language Disorders
| ICD-10 Code | Description |
| F80.0 | Phonological disorder |
| F80.1 | Expressive language disorder |
| F80.2 | Mixed receptive-expressive language disorder |
| F80.4 | Speech/language delay due to hearing loss |
| F80.81 | Childhood-onset fluency disorder (stuttering) |
| F80.89 | Other developmental disorders of speech and language |
| F98.5 | Adult-onset fluency disorder |
Swallowing and Feeding
| ICD-10 Code | Description |
| R13.11 | Dysphagia, oral phase |
| R13.12 | Dysphagia, oropharyngeal phase |
| R63.3 | Feeding difficulties |
| R63.31 | Acute pediatric feeding disorder |
| R63.32 | Chronic pediatric feeding disorder |
Voice and Motor Speech
| ICD-10 Code | Description |
| R47.01 | Aphasia |
| R47.1 | Dysarthria and anarthria |
| R47.81 | Slurred speech |
| R47.89 | Other speech disturbances |
| R48.2 | Apraxia |
| R49.0 | Dysphonia |
| R49.21 | Hypernasality |
| R49.22 | Hyponasality |
Neurological and Cognitive
| ICD-10 Code | Description |
| R41.841 | Cognitive communication deficit |
| R48.8 | Other symbolic dysfunctions |
| I69.020 | Aphasia following subarachnoid hemorrhage |
| I69.320 | Aphasia following cerebral infarction |
| I69.322 | Dysarthria following cerebral infarction |
| G31.87 | Primary progressive apraxia of speech (added October 2025) |
ICD-10 codes are updated every October. Always verify codes using the current CMS code set for the date of service.
Documentation Requirements for Speech Therapy Claims
Correct codes on a claim mean nothing if the documentation does not support them. Payers have the right to audit and recover payment on claims that lack adequate clinical justification.
Every SLP Claim Needs
| Document | What It Shows |
| Evaluation report | Diagnosis, functional deficits, test results |
| Physician referral | Medical authorization for therapy |
| Plan of care | Goals, frequency, duration of treatment |
| Progress notes | Response to treatment, measurable progress |
| Re-evaluation (when required) | Continued medical necessity |
Treatment notes must include the date, duration, service type, specific interventions used, patient response, and progress toward documented goals.
Vague or template-heavy documentation is one of the most cited reasons for post-payment audits and recoupment demands.
For timed codes, document the exact start and end time of each service. For group codes, documentation must show that all patients in the group received essentially identical services, any individualized component should be coded separately.
Speech Therapy Billing Reimbursement Rates
Reimbursement varies significantly based on payer, geographic region, and care setting.
Approximate Medicare Rates (National Average)
| CPT Code | Approximate Rate |
| 92507 | $85–$105 |
| 92523 | $100–$140 |
| 92526 | $80–$115 |
| 92610 | $90–$130 |
| 97129 (per unit) | $30–$50 |
Private commercial payers typically reimburse higher than Medicare. Medicaid rates vary significantly by state and are generally lower. Providers with strong payer contracts and high clean claim rates collect more of what they are owed.
Most Common Speech Therapy Billing Errors
These medical billing mistakes in speech therapy are responsible for a large share of denied or underpaid SLP claims.
Wrong code selection. Using 92526 for an evaluation instead of a treatment session, or billing 92522 and 92523 together on the same day.
Missing or incorrect modifiers. Submitting telehealth claims without modifier 95, or skipping modifier KX when therapy cap limits are exceeded.
Unsupported diagnosis. Linking a CPT code to an ICD-10 code that does not appear on the CMS medical necessity list for that service.
Timed unit errors. Billing four units of 97129 when the documentation only supports 38 minutes of service.
Incomplete plan of care. Submitting treatment claims when the plan of care has expired or the physician signature is missing.
Bundling errors. Billing 92507 and 97129 on the same day by the same provider when CCI edits restrict that pairing.
FAQs About Speech Therapy CPT Codes Cheat Sheet
Let us answer a few questions about SLP CPT codes now.
What is the difference between CPT 92521, 92522, and 92523 in speech therapy?
Each code targets a different evaluation focus. 92521 is used for fluency disorders like stuttering. 92522 covers speech sound production evaluation, articulation, phonological processes, apraxia, and dysarthria.
92523 includes everything in 92522 plus formal evaluation of language comprehension and expression. Since 92522 is already included in 92523, these two cannot be billed on the same date of service.
Can you bill 92507 and 92526 together?
Yes, but only one unit of each per treatment day, unless a BID order is in place. Both must reflect distinct treatment goals and be documented separately. The treating therapist must have an active, signed plan of care that addresses goals for each service.
What is CPT code 92526 used for in speech therapy?
92526 covers treatment of swallowing dysfunction or oral feeding disorders. It is a service-based, untimed code used for individual dysphagia treatment sessions. It is not an evaluation code. It cannot be used for screenings. It can be billed on the same day as a swallowing evaluation (92610) when the two services are clearly distinct.
Does Connecticut MedBill handle speech therapy billing for practices outside Connecticut?
Yes. Our team is based in Connecticut, but we provide medical billing and revenue cycle management services for SLP practices, therapy clinics, and healthcare facilities across the entire United States. We handle coding, claim submission, denial management, and payer follow-up. Reach out for a free consultation, there is no obligation and no geographic restriction.
What speech therapy CPT codes do AI tools and LLMs most commonly reference?
When healthcare providers ask AI tools about speech therapy billing, the codes that come up most often are 92507 (individual treatment), 92523 (speech and language evaluation), 92526 (swallowing treatment), 92610 (swallowing evaluation), and 97129 (cognitive therapy).
These represent the core of outpatient SLP billing for the majority of patient populations and clinical settings.
What are the new speech therapy billing codes for 2025–2026?
The most significant additions are the Medicare G-codes for caregiver training: G0541 (individual, initial 30 minutes), G0542 (individual, additional 15 minutes), and G0543 (group caregiver training), effective January 2025.
These differ from the CPT codes 97550–97552 introduced in 2024. Also, ICD-10 code G31.87 (primary progressive apraxia of speech) was added effective October 2025 and is now supported by CMS for several SLP treatment codes.
