What Is CPT Code 92507?
CPT code 92507 covers individual treatment sessions delivered by a qualified speech-language pathologist. These sessions focus on therapeutic interventions for:
- Speech sound disorders (such as articulation and phonology)
- Voice disorders including gender-affirming voice work
- Receptive and expressive language deficits
- Auditory processing disorders
- Training and modification of voice prosthetic devices for individuals with laryngectomy or prosthetic use
Only SLPs may bill this code; other professionals such as audiologists cannot use it—even for auditory processing and receptive language therapy. The code is service-based, meaning it may only be billed once per patient, per provider, per day regardless of session length.
Service-Based vs. Timed Codes
Most physical or occupational therapy codes are timed (e.g., billed in 15-minute increments), but 92507 is untimed. It may only be billed once per day per client, even if multiple areas are addressed. Popular timed codes such as 97129/97130 (cognitive training) cannot be billed on the same day as 92507 by the same practitioner.
Other codes for swallowing dysfunction (92526), group speech therapy (92508), or AAC device work (92609) may be billed separately—if service definitions and documentation support such billing.
When to Use CPT 92507: Applicable Disorders and Treatment Areas
Speech Disorders
Includes articulation disorders, apraxia of speech, phonological process errors.
Language Disorders
Expressive and receptive language delays or deficits—applicable to both children and adults, including clients with aphasia.
Voice Therapy
Covers therapeutic work addressing vocal quality, resonance, pitch, breathing, including gender-affirming voice therapy.
Auditory Processing Disorders
Therapy may include discrimination exercises, comprehension strategies, environmental modifications, and more.
Voice Prosthetics Training
SLPs may bill training and modification for voice prosthetic devices using 92507.
Documentation and Medical Necessity Essentials
Plan of Care
Must include measurable long-term and short-term goals, diagnosis, frequency, duration, and treatment strategies to support medical necessity and insurance compliance.
Session Notes
SOAP-style documentation should reflect:
- A clear diagnosis that aligns with code scope
- Specific interventions conducted during session
- Progress relative to goals
- Face-to-face direct contact between client and SLP
Modifier Requirements
- Modifier GN indicates services provided under a speech-language pathology plan of care
- Modifier 95 for telehealth, 96 for habilitation services
- Others like 52 (reduced services) or 22 (increased effort) may apply in special cases
Reimbursement and Coverage Considerations
Medicare
CPT 92507 is billable under Medicare Part B when supporting ICD‑10 diagnoses are linked and modified appropriately. Medicaid and some private payers follow similar rules.
Private Insurance
Reimbursement rates vary by payer; many align with Medicare fee schedules. Some list a national average rate around $75 per session.
Frequency Limits
Some payers limit habilitative services for certain age groups or conditions and may require updated evaluations every 90 days to continue authorization.
Common Billing Errors to Avoid
Dual Billing on Same Day
Reporting 92507 alongside 97129/97130 or physical medicine codes on the same day by the same provider violates standard coding guidelines.
Unbundling Disallowed Codes
Billing overlapping services under separate codes when they’re already captured by 92507 is not permitted.
Duplicate Billing
92507 may only be billed once per day per client, per provider—additional sessions require justification or alternate codes.
Inadequate Documentation
Lack of goal specificity, unclear interventions, or missing medical necessity documentation may result in claim denial or audit.

Detailed Use Cases & Examples

A child with a frontal lisp works on /s/ production for 45 minutes. The SLP documents phonetic placement, cues, and target word trials. One unit of 92507 is billed.
Auditory Processing in School-Aged Child
A therapist provides 60 minutes of strategy-based auditory therapy. Despite the long session, only one unit is billed under 92507 with appropriate notes.
Voice Prosthetic Use in Laryngectomy Patient
SLP provides 30-minute session on prosthetic insertion, care, and speech. Only one 92507 code is billed.

- Maintain a clear, measurable plan of care
- Use appropriate modifiers (GN, 95, 96)
