Important update: CPT 92507 remains valid for dates of service through December 31, 2026. On January 1, 2027, it is deleted from the CPT code set and replaced by ten new time-based codes (92654–92663). This guide explains how 92507 works today and what changes next. See the 2027 section for details.
This article covers what 92507 describes, which services fall under it, how to bill it, which modifiers apply, how Medicare and other payers treat it, and how it compares with related speech therapy codes. It is written for SLPs, practice owners, billers and coders. Payer rules differ, so treat the guidance below as a framework and confirm specifics with each payer.
What Is CPT Code 92507?
CPT 92507 Code Description
The CPT descriptor for 92507 reads, in short, treatment of speech, language, voice, communication, and/or auditory processing disorder, individual. The wording is deliberately broad. It does not name a specific diagnosis, technique or session length, which is part of why it has been so widely used, and part of why payers have scrutinized it.
CPT® is a registered trademark of the American Medical Association (AMA), and the official descriptor should always be confirmed in the current CPT code book.
Purpose of CPT 92507 in Speech-Language Pathology
The code tells the payer that a qualified SLP provided skilled, direct treatment to one patient. The claim itself carries very little clinical detail, so the diagnosis codes, the plan of care and the treatment note have to explain what was treated and why it required a skilled clinician. In practice, 92507 identifies the service, and the documentation justifies it.
Is CPT 92507 a Timed or Untimed Code?
It is untimed. The descriptor contains no time unit, so it is reported as one unit per session rather than in 15-minute increments. That distinguishes it from many physical and occupational therapy codes, where units are calculated from minutes.
Untimed does not mean time is irrelevant. Treatment time still belongs in the note, because reviewers use it to judge whether the visit was reasonable. Billers sometimes carry timed-code habits over from therapy billing and enter multiple units for a long session. For 92507, that typically produces a denial or an overpayment risk.
What Services Are Covered Under CPT Code 92507?
The code covers direct treatment, so the question is less "which diagnoses qualify" and more "what is the clinician actually doing with this patient." The categories below reflect the types of treatment commonly reported with 92507. Whether a specific service is payable still depends on the payer, the diagnosis and medical necessity.
Speech Sound and Articulation Therapy
Treatment of speech sound production disorders is the classic use: articulation and phonological disorders, childhood apraxia of speech, and dysarthria after neurological injury. A typical example is a six-year-old working on a specific sound pattern, with the SLP selecting targets, cueing and tracking accuracy across the session.
Language Comprehension and Expression Treatment
This includes receptive and expressive language treatment, such as intervention for language delay in children or aphasia in adults after a stroke or brain injury. A Medicare patient with post-stroke aphasia, for example, may receive naming and sentence-formulation therapy under a certified plan of care, reported with 92507 and the required modifiers.
Voice Disorder Treatment
Voice therapy for conditions such as vocal nodules, vocal fold paralysis or other voice disorders is reported with 92507 when it is individual treatment. The evaluation of voice and resonance is a separate service (92524) and is not billed as treatment.
Communication Disorder Treatment
"Communication" in the descriptor extends to functional communication, including cognitive-communication deficits following brain injury. ASHA's coding guidance notes that cognitive treatment may be reported either with 92507 or with the cognitive function intervention codes 97129 and 97130, but not both on the same day by the same provider. Confirm this against current ASHA and payer guidance before building a billing rule around it.
Auditory Processing and Aural Rehabilitation
ASHA directs treatment for auditory processing disorder to 92507, while the evaluation is coded separately (92523, according to ASHA). Aural rehabilitation is less uniform. Some payers, including certain state Medicaid programs, direct SLP-delivered auditory rehabilitation to 92507, while the CPT code set also contains separate auditory rehabilitation codes. Check the payer policy and the clinician’s scope of practice before choosing a code.
Voice Prosthetic Training and Modification
ASHA’s coding FAQ states that evaluation for a voice prosthetic is reported with 92597, while training and modification in the use of the device are reported with 92507. This applies to patients using devices such as an electrolarynx or a tracheoesophageal speech valve after laryngeal surgery.
CPT Code 92507 Billing Guidelines
Individual vs. Group Speech Therapy Billing
92507 is for one patient. When two or more patients are treated together, the group code, 92508, applies instead. Medicare also has its own definitions of group and individual therapy in the Benefit Policy Manual, so a clinician who treats a child with a parent observing is still providing individual therapy, while two patients receiving therapy at the same time are not.
When to Use CPT 92507
- A qualified SLP provides direct, one-on-one treatment.
- A diagnosis and an evaluation or plan of care support the need for skilled therapy.
- The service is not better described by a more specific code, such as swallowing treatment (92526) or speech-generating device services (92607, 92609).
- The patient’s plan covers the service, or the payer has authorized it where authorization is required.
Required Information for Claim Submission
A clean 92507 claim generally needs the following. Individual payers may add requirements.
- Accurate patient demographics and active insurance details
- Rendering provider and billing provider NPIs, enrolled and credentialed with that payer
- CPT 92507 with the correct modifiers (for example, GN on Medicare Part B)
- ICD-10-CM diagnosis codes that match the treated condition
- Date of service, place of service and one unit
- Referring or certifying provider information where the payer requires it
- Prior authorization number, when applicable
Practices that handle charge entry and claim scrubbing in-house often catch these problems late, after the denial. A structured medical billing workflow that checks modifiers, diagnoses and authorizations before submission prevents most of them.
Can CPT 92507 Be Billed More Than Once Per Day?
As a rule, no. Medicare applies a medically unlikely edit (MUE) that, as commonly published, limits 92507 to one unit per date of service, and many commercial payers follow similar logic. A second, separate session on the same day is a payer-policy question, not a coding shortcut, and it needs clear documentation of why two sessions were medically necessary. Check the current MUE table and the payer’s policy before submitting more than one unit.
Documentation Requirements for CPT 92507
Documentation is where 92507 claims are won or lost. The code is broad, so the record has to show that the services were skilled, individualized and necessary. For Medicare, the baseline requirements are in Chapter 15 of the Medicare Benefit Policy Manual, and Medicare Administrative Contractors (MACs) may add their own expectations. Commercial payers and Medicaid programs publish their own policies.
Medical Necessity Documentation
The record should show a diagnosis, a measurable functional limitation, the reason a skilled SLP is needed, and a reasonable expectation of progress or, where the payer allows it, the need for skilled maintenance. Phrases like "patient tolerated session well" do not establish necessity. A note that links the intervention to a functional goal does.
Speech Therapy Treatment Plan
Under Medicare, therapy must be furnished under a plan of care that includes diagnoses, goals, and the type, amount, frequency and duration of treatment, and it must be certified by a physician or non-physician practitioner as required. An uncertified or expired plan is a common source of denials and post-payment review findings. Other payers may require their own treatment plan formats or periodic updates.
Progress Notes and Measurable Goals
Goals should be functional and measurable, and each treatment note should show what was done and how the patient responded. Medicare sets minimum expectations for periodic progress reports; confirm the current requirement in the manual and your MAC’s guidance. A quick internal audit of a sample of notes is often the fastest way to find gaps. A medical billing audit can help identify patterns before a payer does.
Therapist Documentation and Clinical Findings
Each encounter note should include the date, the treatment provided, the patient’s response, treatment time, and the clinician’s signature and credentials. For telehealth visits, note the modality used and the patient’s location where the payer requires it.
Which Modifier Is Used With CPT Code 92507?
Understanding the GN Modifier
GN indicates that a service was delivered under a speech-language pathology plan of care. CMS uses the GN, GO and GP modifiers to identify the therapy discipline, so a speech therapy line billed to Medicare Part B without GN is at risk of being returned or denied.
When Is the GN Modifier Required?
GN applies to outpatient SLP services billed to Original Medicare Part B. Medicare Advantage plans, Medicaid programs and commercial payers may or may not require it, so verify instead of assuming. When it is required, it goes on every qualifying SLP line, not only the first claim of a course of treatment.
Other Payer-Specific Modifier Requirements
- KX: Medicare uses KX to attest that services above the annual therapy threshold are medically necessary and documented. The threshold is combined for physical therapy and speech-language pathology. For 2026 it is $2,480, and CMS has proposed $2,540 for 2027. Confirm the final figure before billing in 2027.
- 95, GT or place-of-service codes for telehealth: Requirements vary by payer. Medicare and commercial payers have used different combinations, so follow the payer’s current telehealth billing policy.
- State Medicaid or commercial modifiers: Some payers define their own modifiers or authorization rules for therapy. Check the payer’s fee schedule and provider manual.
A Medicare claim for a patient above the threshold might therefore read: 92507 with GN and KX, one unit, with an ICD-10-CM code such as R47.01 (aphasia) supporting the treatment. The right diagnosis code always depends on the clinician’s documentation.
CPT 92507 Reimbursement and Medicare Coverage
Does Medicare Cover CPT 92507?
Original Medicare Part B covers medically necessary outpatient speech-language pathology services when they are furnished by a qualified provider under a plan of care that meets Medicare’s requirements. Coverage is conditional, not automatic. The services must be reasonable and necessary, skilled, and supported by documentation.
It helps to keep payer types separate:
- Original Medicare: follows the national manuals, local coverage articles and the Physician Fee Schedule.
- Medicare Advantage: must cover Part B benefits but can use its own networks, prior authorization and claim rules.
- Medicaid: varies by state, including covered diagnoses, age limits, visit limits and provider types.
- Commercial insurance: depends on the plan, contract and any visit limits or authorization requirements.
Factors Affecting CPT 92507 Reimbursement
- The payer’s fee schedule and your contract rate
- Geographic locality and place of service under Medicare
- Multiple therapy service payment reductions where they apply
- Whether authorization, visit limits or therapy thresholds are reached
- Provider credentialing and enrollment status
- Clean-claim accuracy, including modifiers and diagnosis pairing
Rates change annually. For Medicare, use the CMS Physician Fee Schedule lookup for your locality instead of relying on a number quoted in an article.
Insurance Verification and Payer Policies
Before the first visit, confirm active coverage, whether outpatient speech therapy is a covered benefit, any diagnosis or age restrictions, visit limits, authorization requirements, telehealth coverage and patient cost-sharing. Eligibility verification done up front is one of the least expensive ways to prevent a denial. Also confirm that each rendering SLP is enrolled with the payer; delays in credentialing and payer enrollment can leave perfectly coded claims unpaid.
Common Reasons for CPT 92507 Claim Denials
| Denial trigger | What usually went wrong | Prevention |
|---|---|---|
| Missing or wrong modifier | GN omitted on a Medicare claim, or KX missing above the threshold | Modifier checks in the claim scrubber |
| Medical necessity | Notes do not show skilled need or measurable progress | Goal-linked treatment notes and periodic reviews |
| Plan of care issues | Plan not certified, expired or missing required elements | Certification tracking by date |
| Diagnosis mismatch | ICD-10-CM code does not support the treatment billed | Coder review against documentation |
| Individual vs. group | 92507 billed for a group session, or the reverse | Session type recorded in the note |
| Authorization or visit limits | Visits exceeded the approved number | Authorization tracking |
| Enrollment or timely filing | Rendering provider not enrolled, or claim filed late | Credentialing follow-up and A/R monitoring |
When denials do arrive, the fastest recovery depends on knowing the reason code, correcting the root cause and appealing within the payer’s deadline. A consistent denial management process also shows which problems keep recurring.
CPT 92507 vs. Other Speech Therapy CPT Codes
| Code | What it reports | Type |
|---|---|---|
| 92507 | Individual treatment of speech, language, voice, communication and/or auditory processing disorder | Treatment, untimed (through 2026) |
| 92508 | Group treatment, two or more individuals | Treatment, untimed |
| 92521 | Evaluation of speech fluency (for example, stuttering, cluttering) | Evaluation |
| 92522 | Evaluation of speech sound production | Evaluation |
| 92523 | Evaluation of speech sound production with language comprehension and expression | Evaluation |
| 92524 | Behavioral and qualitative analysis of voice and resonance | Evaluation |
| 92526 | Treatment of swallowing dysfunction and/or oral function for feeding | Treatment |
CPT 92507 vs. CPT 92508
The difference is the number of patients. 92507 is for one patient and 92508 is for two or more treated together. Both are untimed in 2026. Billing group time under the individual code overstates the service and is a classic audit finding.
CPT 92507 vs. CPT 92521
92521 is an evaluation of speech fluency, not treatment. A stuttering evaluation is billed with 92521, and the therapy that follows is billed as treatment.
CPT 92507 vs. CPT 92522 and 92523
92522 evaluates speech sound production, and 92523 adds language comprehension and expression. They assess the patient. They do not replace treatment codes, and evaluation and treatment on the same day should each be supported in the record.
CPT 92507 vs. CPT 92526
92526 covers treatment of swallowing and oral function for feeding. Swallowing therapy is reported with this code, not 92507, even though the same SLP may provide both services.
Common CPT 92507 Billing Mistakes to Avoid
- Incorrect CPT code selection. Using 92507 for swallowing, device programming or evaluation work that has its own code.
- Missing GN modifier when required. One of the most frequent causes of Medicare returns and denials.
- Insufficient medical necessity documentation. Notes that describe activity but not skilled need or functional goals.
- Incorrect diagnosis coding. A diagnosis that does not match the service, or a code chosen for convenience instead of from the clinician’s documentation.
- Incorrect individual vs. group therapy billing. Reporting group sessions as individual treatment, or the opposite.
- Failure to follow payer-specific billing policies. Applying Medicare rules to a Medicaid or commercial plan, or the other way around.
Important CPT 92507 Code Changes in 2027
Why Is CPT 92507 Being Replaced?
According to ASHA, one broad untimed code no longer meets the level of specificity expected under current CPT standards. In 2024, CMS and the AMA flagged 92507 through a high-volume growth screen because Medicare billing for it had grown substantially, which triggered a formal review through the CPT and RUC processes. The result: 92507 is deleted from the CPT code set effective January 1, 2027.
What Are the New Speech Therapy CPT Codes?
Ten new codes replace it, organized by the type of disorder treated. Each category has a base code for the initial 30 minutes of direct, one-on-one treatment and an add-on code for each additional 15 minutes.
| Clinical service | Base code (initial 30 min) | Add-on (each additional 15 min) |
|---|---|---|
| Fluency disorders | 92654 | +92655 |
| Speech sound production disorders | 92656 | +92657 |
| Language comprehension and expression disorders | 92658 | +92659 |
| Combined speech sound production and language disorders | 92660 | +92661 |
| Voice, upper airway dysfunction, and/or resonance disorders | 92662 | +92663 |
Group treatment stays with 92508, which becomes a stand-alone untimed code. Under the general CPT midpoint convention described by ASHA, a base code is typically reportable at 16 minutes of direct treatment, and the first add-on unit at 38 minutes. A 55-minute language session, for example, would generally be reported as one base code plus two add-on units. CPT instructions, CMS rules and payer policies can set different requirements.
Two further points matter. First, ASHA states that the separate speech sound and language codes should not be reported together; the combined codes are used when both areas are treated. Second, CMS has proposed a separate Medicare-only pediatric HCPCS code, GSLPP, in the CY 2027 Physician Fee Schedule proposed rule. It is a proposal, not final policy. Medicare payment values for the new codes are also proposed until the final rule is published.
How Should Providers Prepare for the Transition?
- Keep billing 92507 for dates of service through December 31, 2026. Do not report the new codes early.
- Update the EHR, practice management system and charge master with the new codes and time rules.
- Redesign note templates so each session records the disorder treated and the direct treatment minutes.
- Ask each payer when it will adopt the new codes, how it will price them and whether authorizations need to be reissued. Some payers may continue accepting 92507 for a period, and Medicaid and commercial plans set their own timelines.
- Review contracts and fee schedules, and watch the CMS final rule, NCCI and MUE updates.
- Watch open claims and aging balances across the changeover so that old and new coding rules do not get mixed. Consistent accounts receivable follow-up helps catch these early.
Auditory processing treatment is worth special attention. ASHA’s five new treatment categories do not include a separate auditory processing category, so check ASHA and payer guidance for how these services should be reported after the change.
Frequently Asked Questions About CPT Code 92507
What Does CPT Code 92507 Cover?
It covers individual treatment of speech, language, voice, communication and/or auditory processing disorders delivered by a speech-language pathologist, including articulation, language, voice and fluency work and voice prosthetic training, subject to payer policy.
Is CPT 92507 a Timed Code?
No. It is untimed and reported as one unit per session. The replacement codes that start January 1, 2027 are time-based.
Does CPT 92507 Require the GN Modifier?
On Original Medicare Part B, yes. Other payers vary, so verify each plan’s requirements.
Can CPT 92507 Be Billed for Telehealth?
Often, yes. Congress extended Medicare telehealth authority for speech-language pathologists through December 31, 2027. Medicaid and commercial payers decide their own telehealth coverage, and modifier and place-of-service rules vary, so check each payer before billing.
What Is the Difference Between CPT 92507 and 92508?
92507 is individual treatment, and 92508 is group treatment for two or more individuals.
Does Medicare Reimburse CPT 92507?
Medicare Part B pays for medically necessary outpatient speech-language pathology under a certified plan of care, using the Physician Fee Schedule. Payment varies by locality and is subject to documentation and review thresholds. 92507 itself ends on December 31, 2026.
What Documentation Is Required for CPT 92507?
At minimum: an evaluation or plan of care with diagnoses and measurable goals, evidence of medical necessity, signed treatment notes with the interventions and treatment time, and periodic progress reports. Medicare adds certification requirements, and other payers may add their own.
Simplify Speech Therapy Billing With DocRev RCM
Speech therapy billing gets harder when coding rules change, payers adopt them on different schedules, and documentation expectations rise at the same time. DocRev Rcm is a medical billing and revenue cycle management company that supports healthcare practices across the United States with claim submission, payment posting, denial follow-up and accounts receivable management, backed by eligibility verification and credentialing support.
For speech therapy practices, accurate coding and clean claims go together: the right code, the right modifiers, a diagnosis that matches the note, and a follow-up process for anything that does not pay. DocRev Rcm’s revenue cycle management support covers the full workflow so providers can spend their time on patients. You can browse the practice types supported on the specialties page, or talk to an RCM specialist about your billing workflow.
Conclusion
CPT 92507 covers individual speech, language, voice, communication and auditory processing treatment, billed as one untimed unit per session through December 31, 2026. Getting paid for it depends less on the code than on the work around it: the right modifiers, a diagnosis that matches the service, a certified plan of care where Medicare applies, and notes that show skilled need.
The bigger task now is the transition. From January 1, 2027, the ten new time-based codes replace 92507, and each payer will adopt them on its own schedule. Verify current Medicare and individual payer requirements before billing, and revisit this guide as the CMS final rule and payer policies are published. For help managing the transition, DocRev Rcm offers billing and revenue cycle support for healthcare practices.
