CPT 92507: Complete Billing Guide for Speech-Language Pathologists

CPT 92507 is the most commonly billed code in speech-language pathology. It covers individual treatment of speech, language, voice, communication, and/or auditory processing disorders. If you're an SLP in private practice billing Medicare or commercial insurance, this code is likely on the majority of your claims — which means getting it right is critical for both revenue and compliance.

What CPT 92507 Covers

CPT 92507 is defined as: "Treatment of speech, language, voice, communication, and/or auditory processing disorder; individual." It's an untimed code, meaning it represents a single session regardless of whether the session lasted 30 minutes or 55 minutes. This is different from time-based codes used in physical or occupational therapy.

The code applies to a wide range of SLP treatment activities, including articulation therapy, language intervention, voice therapy, fluency treatment, cognitive-communication therapy, and auditory processing treatment — as long as the service is delivered to one patient at a time.

92507 vs. 92508: Individual vs. Group

The key distinction SLPs need to understand is between 92507 (individual) and 92508 (group — two or more patients). Billing 92507 when you're treating two patients simultaneously, even if you're alternating attention between them, is incorrect and constitutes upcoding. OIG has flagged this specific pattern as an audit trigger for SLP services.

CMS guidance indicates that 92507 requires one-on-one direct contact between the SLP and the patient for the entirety of the treatment session. If a caregiver or family member is present for training purposes, that's still individual treatment. But if a second patient is receiving treatment in the same session, the correct code is 92508.

Required Modifiers

When billing 92507 to Medicare Part B, the following modifiers apply:

• -GN modifier — Required on every SLP service billed to Medicare. This identifies the service as being delivered under an SLP plan of care. Omitting -GN is one of the most common reasons for SLP claim denials.
• -KX modifier — Required when the patient's cumulative therapy charges exceed the annual therapy cap threshold. KX attests that medical necessity documentation exists in the chart.
• Modifier 95 — Required when the service is delivered via synchronous telehealth (audio-video). Not all MACs accept 92507 via telehealth — verify with your local carrier.

When stacking modifiers, CMS guidance indicates the order should be -GN first, then -KX, then -95 if all three are required.

Documentation Requirements

For 92507 to survive a post-payment audit, your treatment note should include:

• Treatment date and session duration
• Specific treatment activities performed — not just "speech therapy provided" but the actual techniques, stimuli, and approaches used
• Patient response data — accuracy percentages, cueing levels, number of trials, specific examples of patient performance
• Relationship to plan of care goals — which goals were addressed and how this session moved the patient toward those goals
• Clinical judgment — your assessment of the patient's performance, any modifications to the treatment approach, and rationale for continued treatment

Medicare Reimbursement for 92507

Medicare Part B reimbursement for CPT 92507 varies by geographic region (based on the Medicare Physician Fee Schedule locality adjustment). As a general reference, the 2026 national average reimbursement for 92507 falls in the range of $75–$95 for the non-facility rate. Your actual reimbursement depends on your MAC, your locality, and whether you're billing at the facility or non-facility rate.

Best practice suggests checking the CMS Physician Fee Schedule lookup tool for your specific locality and MAC to confirm your expected reimbursement before setting your fee schedule.

Common Billing Mistakes with 92507

• Billing 92507 without a current plan of care: Medicare requires a plan of care signed by the treating SLP (and in some cases, a referring physician) before treatment services can be billed. Billing 92507 before the plan of care is established and documented results in automatic denial on review.
• Billing 92507 for evaluation activities: If your "treatment" session is actually spent conducting standardized assessments, administering formal tests, or completing an evaluation, the correct codes are 92521–92524 (evaluation codes), not 92507. Billing 92507 for evaluation activities is a coding error that can trigger recoupment.
• Billing 92507 for supervision or consultation: If you're supervising a clinical fellow (CF) or SLP assistant (SLPA) rather than providing direct treatment, 92507 is not the appropriate code. The "qualified SLP" ruling from mid-2025 has made this a particularly active area of enforcement.
• Missing the -GN modifier: This remains the single most common billing error on SLP Medicare claims. Every 92507 claim to Medicare Part B needs -GN.

NCCI Edit Pairs Affecting 92507

The National Correct Coding Initiative (NCCI) has specific bundling rules that affect 92507. Key edit pairs to be aware of:

• 92507 and 92508 — Cannot be billed on the same date of service for the same patient (individual and group treatment are mutually exclusive per session)
• 92507 and 92521–92524 — Evaluation and treatment codes can be billed on the same date of service with appropriate documentation showing distinct services, but some MACs require modifier 59 or XE to bypass the edit
• 92507 and 97530 — Therapeutic activities; potential bundling issues depending on your MAC's interpretation

NCCI edits are updated quarterly. SLPBillingClarity monitors these changes monthly so you can adjust your billing practices before a denial pattern develops.
