Medical Billing for Speech-Language Pathology Practices

Speech Therapy Billing That Pays What You Earn

Speech therapy billing requires specialty expertise in dysphagia evaluation and treatment coding, language disorder therapy codes, augmentative and alternative communication (AAC) device billing, and the Medicare therapy threshold rules that govern annual expenditure limits. SLP services delivered in hospital outpatient, skilled nursing, school, and private practice settings each follow different billing pathways. 360Solutions provides SLP billing specialists who apply therapy codes precisely, track Medicare thresholds, and manage AAC device prior authorization for your patients.

Where Speech Therapy Practices Lose Revenue

These are the coding and billing pitfalls that cost speech therapy practices the most — and where our specialised billers add the most value.

Dysphagia Evaluation & Treatment

Swallowing evaluation codes (92610 for clinical, 92611 for video fluoroscopy) and treatment (92526) require specific documentation of swallowing mechanism assessment and therapeutic techniques used. Bundling the evaluation and treatment on the same date without correct modifiers causes routine denial.

Medicare Therapy Threshold Tracking

Medicare's annual therapy threshold requires the KX modifier when a patient's combined PT+OT+SLP spending exceeds the soft cap. SLP services share the threshold with OT. Missing KX or incorrect threshold tracking causes automatic claim rejection.

AAC Device & HCPCS Billing

Augmentative and alternative communication device billing uses HCPCS E-codes and requires a speech-generating device evaluation (92597) and prescription from the SLP prior to DME billing. Coordination between professional evaluation billing and device supplier billing is critical.

Medical Necessity Documentation

SLP claims face increasing pre- and post-payment audit activity. Payers require objective functional measures (ASHA NOMS scales, standardized test scores) and documented progress toward measurable goals. Narrative-only notes without objective data are the top audit failure.

Common Denial Patterns

Knowing these before submission is the difference between a 60% and a 96% first-pass rate.

Swallowing evaluation and treatment billed on same date without modifier -59

KX modifier omitted when annual therapy spend exceeds Medicare soft cap threshold

AAC device HCPCS billed without supporting evaluation and physician prescription

Speech therapy units exceed payer-allowed maximum per day

Group therapy code billed for sessions with fewer than two patients simultaneously

Speech Therapy Billing FAQ

Questions From Speech Therapy Practices

We apply modifier -59 to the treatment code when evaluation and treatment are provided in the same session and are separately identifiable services. We document that the evaluation was completed, findings were interpreted, and treatment was then initiated based on those findings.
Yes. Each setting has a distinct billing pathway — outpatient uses standard SLP CPT codes; home health may bundle into the OASIS-based payment system; SNF uses the MDS/PDPM-based billing. We maintain separate billing workflows and payer relationships for each setting.
We coordinate the speech-generating device evaluation, obtain the required physician prescription, prepare the auth request with the AAC assessment documentation, and submit to the DME payer. The evaluation and prescription must be completed before the device is ordered to avoid retroactive denial.
Yes. Post-TBI cognitive communication treatment uses codes 97129/97130 for therapeutic cognitive interventions. We document the cognitive domains addressed, standardized test scores, and functional communication goals to support medical necessity for extended treatment.
