Medicare and Medicaid Billing for Speech Therapy: The 2026 SLP Guide

A patient finishes their twelfth Medicare-billed session of the year, and the next claim quietly denies. The billing team missed that KX kicked in at $2,480.¹ The Medicaid claim that goes out a week later for a different patient pays at a fraction of the Medicare rate, with a different modifier set, in a state with its own unbundling rules.

Medicare billing for speech therapy and Medicaid billing for speech therapy look similar on the surface. They are not the same workflow. Different funding, different rate-setting, different coverage rules, different documentation expectations. Running one billing process for both is where claims go to die.

This guide covers what every Medicare Part B SLP claim has to include in 2026, where Medicaid diverges, the modifiers and thresholds you actually need, and the documentation patterns that hold up under both.

Medicare vs. Medicaid: Two Programs, Two Workflows

Medicare is federal. Federal funding, federal rules, one CMS-set fee schedule, one set of modifiers, one threshold structure that applies the same way in Iowa as it does in California.²

Medicaid is state-administered with joint federal/state funding. Each state sets its own fee schedule, its own coverage rules, and its own provider qualification standards.²

The result? One Medicare rate nationwide for a given CPT code, and 50+ different Medicaid rates by state. Florida pays around $3.74 for 15 minutes of school-based speech therapy. Virginia pays around $31.91 for the same service category.³ Same clinical work, completely different reimbursement reality.

Coverage scope diverges too. Medicare Part B SLP coverage is consistent state to state. Medicaid SLP coverage is federally mandated only for patients under 21 through EPSDT (Early and Periodic Screening, Diagnostic, and Treatment).³ Adult Medicaid SLP coverage is a state option, and plenty of states limit it.

If you bill both programs, you need separate billing logic, separate documentation templates, and separate threshold tracking. Not metaphorically separate, actually separate.

2026 Medicare Reimbursement: What Actually Changed for SLPs

The 2026 Medicare conversion factor is $33.40 for most SLPs and $33.57 for clinicians participating in a qualified Advanced Alternative Payment Model, an increase of roughly 3.3% to 3.8% from 2025.⁴

That sounds like good news. It isn't quite. Congress approved a one-time 2.5% payment increase, but mandatory federal budget reductions and CMS efficiency adjustments may net out to about a 4% cut without further congressional action.⁴

The numbers that matter most for day-to-day SLP billing:

• KX modifier threshold for 2026: $2,480 combined PT + SLP per beneficiary¹
• Targeted medical review threshold: $3,000 (locked in through 2028)¹
• 92507 (individual treatment) non-facility rate: approximately $76.15
• 92508 (group treatment) non-facility rate: approximately $24.05
• Telehealth: all SLP services covered under telehealth since 2020 became permanently covered January 1, 2026⁴

The telehealth change is the quiet one. After years of temporary extensions, audiologists and SLPs now have permanent telehealth coverage in the Medicare benefit, with congressional authority to deliver those services running through December 31, 2027.⁴

The Modifiers Every Medicare Part B SLP Claim Needs

Modifiers carry more weight on SLP claims than most people realize. Miss the wrong one and the claim doesn't even get to the medical-necessity review. It dies at intake.

GN is required on every Medicare Part B SLP claim. It identifies the service as part of an SLP plan of care.⁵ No GN, no payment. This is the single most common preventable denial in multi-disciplinary clinics.

KX is required once the patient's combined PT + SLP services pass $2,480 in 2026. It confirms continued medical necessity for therapy past the threshold.¹ Worth knowing: the claim that pushes the patient to $2,480 doesn't need KX yet. The next one does.

59 is for distinct procedural services on the same day, like an SLP doing individual treatment in the morning and swallowing therapy in the afternoon. Use it where it fits, but overuse triggers audits.⁵

95 is the telehealth modifier for synchronous audio-visual services, which now matters every day because telehealth coverage is permanent.⁴

Then there's the discipline-mix-up problem. GN is for SLP. GP is for PT. GO is for OT. In a multi-disciplinary clinic where one billing team handles all three, putting GP on an SLP claim is an automatic denial, and it happens more often than anyone wants to admit.

A clean 2026 Medicare Part B SLP claim past the threshold typically looks like this: CPT + GN + KX.

The 2026 Therapy Threshold (and the Cap That Isn't a Cap)

People still search for "medicare therapy cap speech" because the muscle memory is sticky. The hard therapy cap was replaced years ago. What's in its place now is the KX threshold and the targeted medical review threshold, which behave differently.¹

Past $2,480 in combined PT + SLP services for the calendar year, every subsequent Medicare claim needs the KX modifier, and the chart has to actually support the medical necessity it's asserting.

Past $3,000, the claim may be flagged for targeted medical review, which means a reviewer may look at the chart and decide whether the services were skilled, necessary, and progress-supported. That $3,000 number is locked in through 2028.¹

Two things make threshold tracking harder than it should be:

The threshold is combined PT + SLP, not separate. A patient who saw a PT for nine visits earlier in the year may already be at the threshold by the time you start SLP services. If you only track your own discipline's billing, you'll miss the crossover.

The threshold resets every calendar year. A patient who hit it in late November starts the next year clean on January 1, which is great for the patient but easy to forget on the billing side.

A workable approach: at intake, pull the patient's accumulated PT + SLP Medicare spend year-to-date. Flag the chart when they're within about $500 of $2,480. That way KX is automatic on the crossover claim instead of a retroactive correction.

Medicaid Billing for Speech Therapy: What Changes State by State

Here's where things get genuinely complicated. There is no national Medicaid rate for any SLP service. Each state's fee schedule is its own document, set by its own Medicaid agency, and updated on its own timeline.

Coverage scope is uneven too. Every state covers SLP services for patients under 21 because EPSDT requires it.³ Adult coverage is a state option. Some states cover adult outpatient speech therapy generously. Others cap it tightly or don't cover it at all.

Provider qualifications vary by state. Some require state licensure plus ASHA certification. Others recognize licensure alone. Schools often have separate qualification pathways that allow certified teachers to deliver speech and language services under SLP "direction" for Medicaid reimbursement. In New York, school-based Medicaid billing requires that those services be delivered by a state-licensed SLP, or by a teacher under documented direction from a licensed SLP.⁶

Unbundling rules vary too. Colorado's Medicaid speech therapy billing manual explicitly prohibits SLPs from reporting 97110, 97112, 97150, 97530, 97127, or G0515 as separate services from 92507, 92508, or 92526.⁷ A generic national billing guide that says "add 97110 for therapeutic exercise" will produce denials in Colorado.

School-based services have their own structure. IEP/IFSP services billed through state Medicaid school-based programs usually require IEP goal alignment in each note, and reimbursement runs through separate fee schedules and provider enrollment paths.³

And telehealth Medicaid policy is state-by-state. Medicare made SLP telehealth permanent. Medicaid hasn't followed that path uniformly.

The practical takeaway? The state Medicaid manual (or its school-based services manual) is the authoritative reference for Medicaid SLP billing, not generic national guidance. If you bill multiple states, you need multiple manuals open.

Documentation That Holds Up Under Both Programs

The good news is that Medicare and Medicaid medical-necessity reviews are looking for the same core elements: an individualized plan of care, measurable functional goals, ongoing progress measurement, and clinical justification for continued treatment.⁵

The Medicare specifics:

• Plan of care signed by the physician or NPP within 30 days
• Progress notes at least every 10 visits or 30 days, whichever is shorter
• Recertification at least every 90 days
• 8-minute rule on timed codes (only face-to-face treatment minutes count, not chart review or report writing done outside the patient's presence)⁵

Medicaid adds:

• State-mandated documentation elements (check the state manual)
• For school-based services: IEP goal alignment in each note
• For Medicaid Managed Care plans: prior authorization, often with utilization caps

Documentation that fails under either program usually fails for the same reasons. Vague progress descriptors ("patient is doing better"). No measurable baselines. No clinical justification for continued treatment past a threshold. Missing supervisor sign-off when a student or SLPA delivered the session. None of those are clinical problems. They're workflow problems.

The fix is making the documentation requirements part of the note template, so a clinician finishing a SOAP note can't skip the fields a reviewer is going to ask about. That's where a documentation system that ties plan of care, progress measurement, CPT/ICD-10 linking, and supervisor sign-off into a single record actually changes the denial rate.

Common Medicare and Medicaid SLP Billing Denials (and How to Prevent Them)

After all that, here's the short list. These are the denial patterns that come up over and over in Medicare and Medicaid SLP billing:

1. Missing GN on a Medicare Part B SLP claim. Automatic denial.⁵
2. Missing KX once the patient crosses $2,480. Easy to miss at month-end if no one is tracking the threshold.¹
3. Wrong discipline modifier (GP or GO on an SLP claim). Common in multi-disciplinary clinics.
4. Documentation that doesn't justify continued medical necessity past the $3,000 targeted review threshold. Claim flagged, sometimes clawed back.¹
5. CPT/ICD-10 mismatch. Billing 92507 with a dysphagia diagnosis (R13.10) instead of 92526.
6. State-specific Medicaid unbundling errors. Billing 97110 separately from 92507 in a state that prohibits it.⁷
7. School-based Medicaid claims without IEP goal alignment in states that require it.
8. Missing supervisor sign-off on student or SLPA work in states where direction documentation is required.⁶

Most of these get caught by a five-second pre-submission check. The trick is building the check into the workflow, not running it as a month-end audit when the denials are already in.

One Documentation System, Two Payer Logics

Medicare billing for speech therapy and Medicaid billing for speech therapy share CPT codes, share clinical fundamentals, and share most of the documentation principles. But they are structurally different programs. Different rates, different modifier requirements, different threshold structures, different state-by-state variation.

The 2026 specifics worth pinning to your billing process: KX threshold at $2,480, targeted medical review at $3,000, permanent SLP telehealth, conversion factor at $33.40 for most SLPs. Medicaid adds 50 state-specific fee schedules, EPSDT coverage for patients under 21, and state-by-state provider and unbundling rules on top of all of that.
