What Are the Insurance and Billing Guidelines for Speech Therapy

Speech therapy billing can feel overwhelming. Between speech therapy insurance coverage, changing rules, and complex speech CPT codes, it can quickly become a full-time job. That’s why we created this guide—to help you get paid faster, with less stress. Simple instructions on what to include in your notes, how to comply with regulations, when therapy is deemed required, and how to prevent your claims from being rejected are provided inside.

Whether you're a solo SLP or running a clinic, this breaks down exactly what you need to bill correctly and confidently.

How Do Speech Therapy Insurance Rules Differ from Other Types of Coverage

Medicare, private insurers, and Medicaid all have their own rules—and missing a detail could cost you.

Medicare Coverage

• Part A (Inpatient) – Covers speech therapy during hospital or rehab facility stays.

• Part B (Outpatient) – Pays 80% of the approved amount with no annual cap for medically necessary care.

• Part C (Medicare Advantage) – Must match Original Medicare, but often adds prior authorization or network limits.

Private Plans: Require pre-authorization and set session limits. Many require updated documentation every 30–90 days.

Medicaid & State Variances: Each state sets its Local Coverage Determinations (LCDs) you need to uncover what applies in your region.

Knowing your speech therapy insurance rules upfront prevents claim delays and lost revenue.

Coding Strategies & Code Compliance

Once you're clear on coverage, you need to speak insurers' language: accurate CPT codes, speech therapy, and modifiers.

Core Codes

Code	Description
92507	Speech-language treatment
92526	Dysphagia treatment
92607–92609	AAC evaluation and intervention
92521–92524	Re-evaluation of speech-language status

Using the updated speech therapy treatment codes 92521–92524 range avoids misuse tied to the obsolete 92506.

Evaluation Codes

• The speech therapy evaluation CPT code (e.g., CPT code for speech therapy evaluation) and the CPT code for speech therapy evaluation and treatment ensure medical necessity is clearly documented.

• Providers often ask, “Can you bill 92507 and 92526 together?” Generally, no—unless the documentation shows distinct services and modifier 59 is applied.

Time-Based Billing

Most CPT codes for speech therapy are billed in 15-minute units. Know the difference between timed and untimed codes and apply speech therapy treatment codes carefully.

Modifiers

GN – outpatient speech-language under Medicare

95 – telehealth delivery

22 – increased complexity

59 – distinct service from another billed code

Incorrect use of speech therapy modifiers is one of the top reasons claims get denied.

Bundling Rules

Medicare’s NCCI edits prohibit billing PT codes (e.g., 97110) with SLP codes for the same session.

Establishing Medical Necessity & Documentation Standards

Coding is half the battle. Without solid documentation, your claims risk denial.

• Physician-ordered Plan of Care – Must outline medical necessity, functional goals, and anticipated outcomes.

• SOAP notes – Include objective findings, dates, detailed ICD‑10, and provider signature—clear enough for varied clinical reviewers.

• Annual Thresholds – Once therapy costs reach $2,410 (for PT & SLP combined), a KX modifier is mandatory; costs above $3,000 drive targeted medical review.

• Clean documentation ensures faster 92507 CPT code reimbursement and reduces audit risks.

What Steps Are Involved in Submitting Claims and Avoiding Denials

• Start with eligibility verification: Use X12‑270/271 before each session to confirm coverage.

• Use the correct claim form

  • CMS‑1500 for private practices

  • UB‑04 for institutional settings

• Submit claims electronically: Send via X12‑837 through a clearinghouse.

• Track submission status

  • X12‑997 confirms receipt

  • X12‑835 reports payment or rejection

• Act quickly on denials

  • 26% of denials stem from registration errors

  • If not corrected fast, 65% of denials may never be recovered

• Keep documentation strong: Accurate notes and clean claims reduce payment delays.

• The right speech therapy billing software can automate this process, applying the proper SLP billing codes and flagging errors before submission.

What Are the Telehealth Billing Rules for Speech Therapy Services?

• Use the –95 modifier: Required on claims to indicate telehealth delivery.

• Make sure you're using only secure, authorized tools that adhere to privacy rules in order to protect client information.

• Verify state licensure: You must be licensed in the client’s state, especially for cross-state services.

• Check payer-specific rules: Every insurance plan may have its own telehealth billing conditions.

• It is anticipated that the use of internet therapy will continue to increase by around 10% annually until 2028.

• Know your impact: Pediatric speech teletherapy shows 70–90% success rates with proper implementation.

Follow updates from CMS, Medicaid, and private insurers to avoid denials.

How to Stay Audit-Ready and Avoid Billing Compliance Issues

• Staying compliant with speech therapy billing isn’t optional—it’s essential. 

• As payer audits become more aggressive, you need to stay ahead. That means keeping up with Medicare Administrative Contractor (MAC) Local Coverage Determinations (LCDs), CMS rule changes, and updates from ASHA. 

• Your documentation should be clean, legible, and ready to review at any time. 

• Auditors will flag anything that looks like overuse of codes like CPT code 92507 speech therapy, improper modifiers, or services that don’t match medical necessity. 

• Overbilling, even if unintentional, can lead to serious consequences, including legal action.

• Stay organized, double-check your claims, and don’t ignore small mistakes—they’re what usually trigger bigger problems later.
