How to Create a Superbill for Out-of-Network Therapy: The Definitive Guide (2026)
If you're a therapist, LPC, LCSW, LMFT, or psychiatrist who sees out-of-network (OON) clients, the superbill is one of the most powerful — and most misunderstood — documents in your practice. Done right, it gets your clients reimbursed quickly and keeps your practice out of payer crosshairs. Done wrong, it leads to denied claims, frustrated clients, and potential compliance headaches.
This guide breaks down exactly how to create a superbill for out-of-network therapy, what every required field means, which CPT codes to use, and how to avoid the most common mistakes that trigger rejections from payers like Aetna, Cigna, UnitedHealthcare, and BlueCross BlueShield.
What Is a Superbill — and Why Does It Matter?
A superbill is an itemized receipt that a healthcare provider gives to a patient. It contains all the clinical and billing information an insurance company needs to process a reimbursement claim on behalf of the patient — even when the provider is out-of-network.
Unlike a standard receipt, a superbill is a quasi-claim document. It includes diagnosis codes (ICD-10), procedure codes (CPT), provider credentials, and service details. When a client submits it to their insurer, the payer uses it to determine whether the service is covered under the client's out-of-network benefits and how much to reimburse.
Why this matters for your practice:
- It's one of the top reasons clients choose OON providers — they can still get partial reimbursement
- A poorly formatted superbill is the #1 reason OON reimbursement claims get denied
- Superbills are considered medical records and must be HIPAA-compliant
- Payers like Cigna and Aetna have specific formatting requirements, and they will reject vague or incomplete documents
Who Can Issue a Superbill for Therapy?
Not everyone can issue a superbill. The provider listed must be a licensed clinician with a valid National Provider Identifier (NPI). Here's a quick breakdown by credential:
| Credential | Can Issue Superbill? | Notes |
|---|---|---|
| Licensed Professional Counselor (LPC) | ✅ Yes | Must have individual NPI |
| Licensed Clinical Social Worker (LCSW) | ✅ Yes | Must have individual NPI |
| Licensed Marriage & Family Therapist (LMFT) | ✅ Yes | Some payers restrict reimbursement by state |
| Psychologist (PhD/PsyD) | ✅ Yes | Full billing privileges with most payers |
| Psychiatrist (MD/DO) | ✅ Yes | Can bill medical + mental health codes |
| Registered Intern / Supervised Trainee | ⚠️ Varies | Many payers won't reimburse unlicensed clinicians; must bill under supervisor's NPI in most states |
| Life Coach / Unlicensed Counselor | ❌ No | Not a recognized provider type for insurance billing |
Important: If you're a pre-licensed therapist working under supervision, your clients may not be able to get OON reimbursement at all unless you bill under your supervisor's NPI — and only if your supervisor is willing to take on that clinical and billing responsibility.
The 15 Required Fields on Every Therapy Superbill
Think of these as non-negotiable. Missing even one can result in a payer rejection. Here's every field you need:
1. Provider Information
- Full legal name of the treating clinician
- Professional credentials (e.g., LCSW, LPC, PhD)
- NPI Number (Type 1) — This is the individual provider NPI
- Group/Practice NPI (Type 2) if billing through a group practice
- Tax Identification Number (TIN) or Social Security Number (SSN) — required for payer processing
- Practice name and address
- Phone number
2. Client (Patient) Information
- Full legal name (must match insurance card exactly)
- Date of birth
- Address
- Insurance member ID (helpful but not always required)
3. Service Details
- Date of service — each session needs its own line item
- Place of service (POS) code — typically 11 (Office) or 02 (Telehealth) or 10 (Telehealth in patient's home)
- CPT code for the service rendered
- ICD-10 diagnosis code(s) — at minimum one; up to four on most claim forms
- Session duration/units (especially for timed codes)
- Fee charged per session
- Amount paid by the client
4. Rendering Provider Signature
Some payers require a signature or a "signature on file" attestation. Always include it.
Choosing the Right CPT Codes for Mental Health Superbills
Using the wrong CPT code is one of the most expensive mistakes a therapist can make on a superbill. Here are the codes you'll use most:
Individual Psychotherapy (Most Common)
| CPT Code | Service | Typical Duration |
|---|---|---|
| 90837 | Individual psychotherapy | 60 minutes |
| 90834 | Individual psychotherapy | 45 minutes |
| 90832 | Individual psychotherapy | 30 minutes |
| 90839 | Psychotherapy for crisis | First 60 minutes |
| 90840 | Psychotherapy for crisis (add-on) | Each additional 30 min |
Pro tip: 90837 (60-minute session) is the most commonly billed code in outpatient therapy. However, the session must actually be 53–60 minutes of face-to-face psychotherapy to qualify. If your sessions run 45–52 minutes, use 90834. Upcoding — billing 90837 for a 45-minute session — is a compliance violation.
Evaluation and Management + Psychotherapy (Psychiatry)
| CPT Code | Service |
|---|---|
| 90792 | Psychiatric diagnostic evaluation with medical services |
| 90791 | Psychiatric diagnostic evaluation (no medical services) |
| 99213 + 90833 | E/M visit (moderate complexity) + psychotherapy add-on (30 min) |
| 99214 + 90833 | E/M visit (high complexity) + psychotherapy add-on (30 min) |
Group and Family Therapy
| CPT Code | Service |
|---|---|
| 90847 | Family psychotherapy with patient present |
| 90846 | Family psychotherapy without patient present |
| 90853 | Group psychotherapy |
ICD-10 Codes: Getting the Diagnosis Right
Your diagnosis must be clinically appropriate, documented in the client's medical record, and match the presenting problem. Here are the most common ICD-10 codes used in outpatient behavioral health:
- F32.1 — Major depressive disorder, single episode, moderate
- F33.1 — Major depressive disorder, recurrent, moderate
- F41.1 — Generalized anxiety disorder
- F41.0 — Panic disorder
- F43.10 — Post-traumatic stress disorder, unspecified
- F40.10 — Social anxiety disorder
- F90.0 — ADHD, predominantly inattentive type
- F60.3 — Borderline personality disorder
- Z71.89 — Counseling for other concerns (used for subclinical presentations)
Key rule: Never assign a diagnosis you haven't formally assessed for or documented in your clinical notes. The diagnosis on the superbill must be supported by your session documentation. This is one of the most common audit triggers.
Step-by-Step: How to Create a Superbill
Here's the practical workflow:
Step 1: Collect all required provider information upfront.
Before you see your first OON client, have your NPI, TIN, credentials, and practice address documented and ready to populate.
Step 2: Gather client and insurance information at intake.
Get a copy of the client's insurance card. Note the member ID and group number. This helps clients when they submit the superbill.
Step 3: Complete your clinical note first.
Your diagnosis and session details on the superbill must match your clinical documentation. Always finalize your note before generating the superbill.
Step 4: Select the correct CPT code based on actual session time.
Don't guess. Log your session start and stop times and bill accordingly.
Step 5: Generate the superbill after each session or on a monthly basis.
Some clinicians issue superbills per session; others do monthly batches. Monthly is fine as long as each session is itemized on a separate line.
Step 6: Deliver the superbill securely.
Use a HIPAA-compliant method — a secure client portal, encrypted email, or your EHR. Texting a superbill as a plain attachment is a HIPAA violation.
Step 7: Educate your client on submission.
Clients submit the superbill directly to their insurer via mail, fax, or the insurer's member portal. Tell them to keep a copy and note the submission date.
Superbill vs. CMS-1500: What's the Difference?
A lot of providers confuse these two documents. Here's a quick breakdown:
| Feature | Superbill | CMS-1500 Claim Form |
|---|---|---|
| Who submits it | The patient submits to their insurer | The provider submits to the insurer |
| Used for | Out-of-network reimbursement | In-network and direct billing |
| Format | Flexible (no standard form required) | Standardized government form |
| Electronic version | Not applicable | 837P electronic transaction |
| Provider assignment | Provider not required to be credentialed | Provider must be credentialed (in-network) |
The superbill is not a claim — it's the supporting document that empowers your client to file their own claim. That's an important distinction for both compliance and client communication.
Common Superbill Mistakes That Lead to Claim Denials
Avoid these errors at all costs:
- Wrong or missing NPI — The NPI must be a valid, active Type 1 NPI registered with NPPES.
- Mismatched client name — The name on the superbill must match the insurance card exactly. "Elizabeth" vs. "Liz" can trigger a rejection.
- Incorrect place of service code — Telehealth sessions must use POS 02 or 10, not POS 11 (office). Many payers rejected telehealth superbills during 2020–2023 for this exact reason.
- Upcoding session length — Billing 90837 for a session that was actually 45 minutes is a federal compliance violation, full stop.
- No diagnosis code — Every superbill line item must have at least one ICD-10 code. "Therapy" is not a diagnosis.
- Missing TIN — Payers need your Tax ID to process reimbursement. Without it, claims sit in limbo.
- Vague or generic session descriptions — Some payers require a description of the service in addition to the CPT code.
- Not documenting the session in your clinical notes — If it's not in your notes, it didn't happen. A superbill without a corresponding clinical note is an audit liability.
What OON Reimbursement Rates Look Like in 2026
Out-of-network reimbursement rates vary significantly by payer and plan. Here's a general landscape for outpatient psychotherapy (CPT 90837):
| Payer | Typical OON Reimbursement Approach |
|---|---|
| UnitedHealthcare | Often reimburses at 50–70% of "Allowed Amount" after deductible |
| Aetna | Typically 60–80% of UCR (Usual, Customary & Reasonable) |
| Cigna | Varies; many plans use 60% coinsurance after OON deductible |
| BlueCross BlueShield | Highly plan-specific; PPO plans often have OON benefits, HMOs usually don't |
| Anthem | Similar to BCBS; varies by state and plan tier |
Educate your clients: Most OON plans have a separate (higher) deductible — often $1,500–$5,000 — that must be met before reimbursement kicks in. Once the deductible is met, the client typically receives 50–80% back on each session. This is a conversation worth having at intake.
FAQ: Superbills for Out-of-Network Therapy
Q1: Can I charge for creating a superbill?
Yes. Some practices charge an administrative fee of $5–$25 per superbill, especially if they're generating individual superbills per session. Be transparent about this fee in your intake paperwork.
Q2: How far back can clients submit superbills for reimbursement?
Most payers allow claims to be submitted within 90 to 180 days of the date of service. A few plans allow up to one year. Encourage clients to submit promptly — the further back they go, the more likely the claim is to be denied for timely filing.
Q3: Do I need to be credentialed with an insurance company to issue a superbill?
No. That's the beauty of the OON model. You don't need to be in-network or credentialed with any payer to issue a superbill. You just need a valid NPI and licensure.
Q4: What if my client's plan doesn't have OON benefits?
HMO plans typically don't cover OON services except in emergencies. If a client has an HMO, they will likely receive zero reimbursement regardless of how perfect the superbill is. Always advise clients to call the member services number on their insurance card before their first session to verify OON benefits.
Q5: Can I issue a superbill for teletherapy sessions?
Absolutely — and post-2020, telehealth OON reimbursement has become broadly accepted. Use POS code 02 (Telehealth, provider location) or POS 10 (Telehealth, patient's home) depending on your payer. Do not use POS 11 (Office) for telehealth. Also note: some payers require a telehealth-specific modifier (e.g., modifier 95 for synchronous telehealth).
Q6: Is a superbill the same as a receipt?
Not quite. A receipt confirms payment. A superbill includes clinical billing information (CPT codes, ICD-10 codes, NPI, etc.) that a receipt does not. Many clients mistakenly try to submit plain receipts for OON reimbursement and get denied. Always issue a proper superbill.
Q7: What if I make an error on a superbill I've already given to a client?
Issue a corrected superbill with "CORRECTED" noted at the top and the original date of service. Document in the client's record that a correction was made and why.
Keeping Superbills Audit-Ready
Superbills are considered part of a client's medical record. That means:
- Retain them for a minimum of 7 years (or longer depending on your state — some require 10 years for minors)
- They must be consistent with your clinical notes — same diagnosis, same dates, same provider
- They must be stored and transmitted in a HIPAA-compliant manner
- If you're audited, a payer (or state board) can request both the superbill and the corresponding session note — they need to match
This is exactly why your clinical documentation workflow matters just as much as the superbill itself. Sloppy notes = audit risk, even if your superbill is perfectly formatted.
