Your credentials and NPI number
Your full name, CCC-SLP credential (Certificate of Clinical Competence in Speech-Language Pathology from ASHA), state license number, and NPI. These are required on superbills and expected on any professional invoice. Including them also signals that you are a licensed clinician, which matters to parents and clients navigating the often confusing private-pay vs. insurance landscape.
Client name and date of service
Client's full name (and guardian's name if a minor) and the exact date of each session. For monthly invoices covering multiple sessions, list each date separately — insurance and FSA/HSA submissions require individual dates of service, not date ranges.
CPT codes for superbill clients
Common CPT codes: 92507 (treatment of speech, language, voice disorders — individual), 92508 (group treatment), 92521–92524 (evaluation codes for fluency, voice, resonance, language). Pair with ICD-10 diagnosis codes: F80.0 (phonological disorder), F80.1 (expressive language disorder), F80.2 (mixed receptive-expressive), R47.81 (childhood-onset fluency disorder/stuttering). Without CPT + ICD codes, insurance rejects the superbill claim.
Session duration
CPT codes for SLP treatment are typically billed in 15-minute units. State session duration explicitly: '45-minute individual treatment session (3 units of 92507).' This is what the insurance carrier needs to adjudicate the claim.
Treatment focus
A brief note: 'Focus: /r/ articulation, phonological awareness, following multi-step directions.' This is both good clinical practice documentation and a helpful client record. Parents of child clients especially value seeing what was addressed.
Place of service
Whether the session was in-person (your office or the client's home) or via teletherapy, note it. Teletherapy CPT codes are billed identically to in-person but require a Place of Service code of 02 on claims. For superbills, noting 'Telehealth' is sufficient.
Evaluation vs. treatment invoicing
Evaluations are billed differently from treatment (different CPT codes, higher rates, and sometimes a written report fee). Invoice evaluations separately from ongoing treatment sessions. Common evaluation invoice addition: 'Written evaluation report: $150' (if you charge separately for the report).
Payment terms
Self-pay clients: collect at session or same-day invoice. Package clients: track session balance on each invoice. School contracts: Net 30–60 per contract terms. FSA/HSA clients: they pay you, then submit the superbill for reimbursement — your invoice and their payment receipt are what they submit.

5 invoicing rules for speech therapists
Always include your NPI and license number on superbills
A superbill without your NPI is not processable by insurance. Your license number establishes that you are a licensed provider in the state where services were rendered. These two numbers belong on every clinical invoice — not just when you remember to add them.
Bill by CPT code units, not by session count
Insurance carriers adjudicate by CPT code and units, not by the number of appointments. A 45-minute session is 3 units of 92507. A 30-minute session is 2 units. Bill in units consistently — it's the standard your clients' insurers expect, and it makes superbills submittable without correction.
Invoice school districts for all contract services — not just direct therapy
School district contracts often include more than direct treatment hours: IEP meetings, progress report writing, consultation with teachers, evaluation writing time. Invoice all contracted services separately with agreed rates. Many SLPs undersell district work by billing only treatment time and absorbing administrative hours — those hours are billable.
Keep clinical records separate from billing records
HIPAA governs your clinical notes. Financial records (invoices, payment receipts) are business records with different retention requirements. Keep them in separate systems. A client's invoice shouldn't contain detailed clinical information beyond the session description and CPT codes needed for billing.
Send superbills promptly — insurance has filing deadlines
Most insurance carriers have timely filing requirements: 90 days to 12 months after the date of service, depending on the plan. If a client asks for a superbill months after services, they may already be past their carrier's filing window. Send superbills within 30 days of service, and offer to send them monthly for ongoing clients. This is a client service that builds loyalty.
Frequently asked questions
What's the difference between an invoice and a superbill for speech therapy?↓
An invoice is a request for payment. A superbill is a specialized invoice that contains all the clinical and billing information an insurance company needs to process an out-of-network reimbursement claim — CPT codes, ICD-10 diagnosis codes, NPI, date of service, place of service, units billed, and fees charged. Self-pay clients who never submit to insurance need a regular invoice. Clients seeking out-of-network reimbursement need a superbill.
Do speech therapists need to be ASHA-certified to invoice privately?↓
ASHA's CCC-SLP credential is not legally required to practice in all states — state licensure requirements vary. However, CCC-SLP is the professional standard, is required by most insurance carriers and school districts, and is what most private-pay clients expect. Check your state's licensure requirements. Invoicing without the appropriate state license can expose you to legal liability.
Can parents use FSA/HSA to pay for private speech therapy?↓
Yes. Speech therapy services provided by a licensed SLP are FSA/HSA-eligible. The parent pays you, then submits your invoice and their payment receipt to their FSA/HSA administrator for reimbursement. Your invoice should include your credential, NPI, the diagnosis or treatment description, and the date of service. Some FSA administrators require a letter of medical necessity — you can note on the invoice that one is available upon request.
How do I invoice for an evaluation?↓
Evaluations use different CPT codes than treatment: 92521 (fluency), 92522 (articulation), 92523 (language comprehension), 92524 (behavioral/qualitative analysis), 96125 (standardized cognitive testing). Invoice the evaluation separately from ongoing treatment. If you charge separately for writing the evaluation report (separate from the testing session), invoice that as its own line item: 'Evaluation report — written summary and recommendations: $X.'
What's the best way to handle insurance rejection of a superbill?↓
First, identify the rejection reason (missing NPI, incorrect CPT code, untimely filing, non-covered service, etc.). Correct the error and resubmit if within the filing window. For services denied as 'not medically necessary,' the parent can file an appeal with clinical documentation — you may need to provide a letter of medical necessity. Keep records of every superbill you issue in case clients need a resubmission.
