Speech Therapy Billing Services That Get You Paid

Speech therapy billing depends on precise coding, timing, and authorization tracking. Small errors lead to big delays.
Medhasty Billing keeps your claims accurate, compliant, and moving without interruptions.

SLP Billing Is Different. Most Billers Don't Know That

Speech therapy billing is not physical therapy billing. It is not general medical billing. It has its own codes, its own modifiers, and its own coverage rules. Most general billers learn on the job. They make mistakes. Claims deny. Revenue leaks.

The denials nobody warns you about

Speech therapy claims deny for reasons that do not apply to other specialties. Missing CQ modifier for assistant services. Wrong POS code for telepractice. Incorrect AAC device coding. Payers reject claims for these errors every day. Most billers do not even know they exist.

Why general billers fail speech therapists

General billers apply general rules. Speech therapy needs speech-specific rules. The difference between 92507 and 92508 matters. The difference between modifier GP and modifier CQ matters. The difference between POS 02 and POS 10 matters. General billers miss these distinctions. Speech therapists lose revenue.

What is leaking from your revenue

Untrained billers leave money on the table. Missed charges for evaluation services. Denied claims for missing modifiers. Underpaid claims for wrong code selection. Unworked denials that age past timely filing. Each leak seems small. Together, they cost speech therapy practices thousands per month.

We Know the Codes. Every Single One

POS 02 vs. POS 10 — which one are you filing?

Place of Service Code

Description

Telehealth provided in patient’s home

Telehealth provided in other location

When to Use

Patient at home for real-time video visit

Patient at school, clinic, or another site

POS 02 is for patients at home. POS 10 is for patients at other locations. Using the wrong POS code triggers payment denials. Check each payer’s telepractice policy before submitting.

Modifiers That Make or Break Your Claims

The CQ modifier

Modifier CQ indicates that an outpatient physical therapy or speech-language pathology service was furnished in whole or in part by a physical therapist assistant or speech-language pathology assistant. Use CQ for assistant-provided services under Medicare Part B. Missing CQ means denied claim or recoupment.

Modifier GP, KX, and 59

Modifier

Use in Speech Therapy

Services delivered under an outpatient physical therapy/speech therapy plan of care

Medical necessity requirements met for therapy cap exceptions (Medicare)

Distinct procedural service – for separate and distinct services on same day

Separate structure – use instead of 59 when applicable

GP is required on all outpatient speech therapy claims. KX is required when therapy exceeds annual cap limits. Use 59 or XS for services performed at different times or different anatomical sites.

SLPA supervision billing

Speech-language pathology assistants (SLPAs) cannot bill independently. Services provided by an SLPA must be billed under the supervising SLP. Add modifier CQ to indicate assistant involvement. Document the supervisory SLP’s presence and oversight. Some state Medicaid programs have additional supervision requirements.

Documentation That Holds Up Under Audit

Auditors target speech therapy. Common audit findings include missing physician certification, inadequate progress notes, and lack of medical necessity for continued treatment. We require documentation that includes:

Physician-approved plan of care (initial and recertification)

Specific treatment goals with measurable objectives

Daily progress notes linking treatment to goals

Justification for continued treatment when progress plateaus

Supervision documentation for SLPA services

Coverage Rules Across Every Payer Type

Medicare Part B

Medicare covers speech therapy under outpatient therapy benefits. Annual cap limits apply. Use GP modifier on all claims. Use KX when exceeding cap limits. Coverage requires a physician-approved plan of care. Prior authorization is not required for most services but check your MAC.

Medicaid

Medicaid coverage varies by state. Most states cover speech therapy for children under EPSDT. Adult coverage varies. Some states require prior authorization for all speech therapy. Some limit visits per year. Some require specific documentation. Check your state’s Medicaid provider manual.

School-based vs. clinic-based

School-based speech therapy is often covered by the school district under IDEA, not by Medicaid. Clinic-based speech therapy bills to Medicaid or commercial insurance. Some states allow Medicaid billing for school-based services. Others do not. Know the difference. Do not bill the wrong payer.

Private insurance

Commercial payer policies vary widely. Some cover unlimited visits. Some cap at 20 or 30 per year. Some require prior authorization. Some cover telepractice. Some do not. Verify benefits before every new patient. Document authorization numbers. Track visit limits.
