Free Superbill Template for Therapists (2026)

If you are a therapist in private practice, you likely need to generate superbills for out-of-network clients on a regular basis. This guide walks through every field a compliant superbill must contain — and shows you how to fill each one correctly so your clients get reimbursed without delays.

What Is a Superbill?

A superbill is an itemized statement that combines a receipt with the medical codes insurers need to process an out-of-network reimbursement claim. It is not the same as a plain invoice. Without the correct CPT and ICD-10 codes, your client's insurance company will simply reject the claim. For a deeper dive into what makes a superbill different from a regular invoice, see the required fields on a superbill checklist.

The Required Fields — Field by Field

1. Provider Information

Your legal name exactly as it appears with your licensing board, your license number and state, your NPI (National Provider Identifier), and your EIN or SSN for tax purposes. Every single one of these is required. Missing any provider identifier is the most common reason insurers return superbills unprocessed.

2. Practice Address and Contact

Use the address tied to your NPI registration — the one that appears in the NPPES registry. If you practice at multiple locations, use the address where the session took place.

3. Client / Patient Information

Full legal name (as it appears on the insurance card), date of birth, member ID number, and the name and relationship of the primary policy holder if the client is a dependent. A single character mismatch between the superbill name and the insurance record will delay the claim.

4. Date of Service

List each session on its own line with the exact date. Never bundle multiple sessions into a single date range — insurers process claims line by line and bundled dates are a red flag.

5. CPT Code

The Current Procedural Terminology code tells the insurer exactly what service was provided. For individual therapy the most common codes are 90837 (60-minute psychotherapy), 90834 (45 minutes), and 90832 (30 minutes). For an initial evaluation you would typically bill 90791.

6. ICD-10 Diagnosis Code

The ICD-10 code is the diagnosis. Insurance will not pay for a service without a covered diagnosis attached to it. A common example is F41.1 for generalized anxiety disorder. Make sure the code is specific — F41.9 (unspecified anxiety) is harder to get covered than F41.1.

7. Place of Service Code

POS 11 is used for an office-based session. POS 02 is for telehealth delivered from a clinical setting. POS 10 is for telehealth delivered to the patient at home — which became the standard during and after the pandemic. Using the wrong code will cause a mismatch with your clinical notes.

8. Fee Charged and Amount Paid

List your full session fee, any discount applied (such as a sliding scale adjustment), and the amount actually collected from the client. Insurers use this to calculate the reimbursable portion.

9. Provider Signature

Many insurers still require a wet or electronic signature from the treating provider. A stamped or typed signature is generally acceptable, but check with your top payers to confirm their requirements.

A Sample Superbill Template (Filled Out)

Here is what a completed superbill looks like in practice:

• Provider: Sarah Nguyen, LCSW | NPI: 1234567890 | EIN: 98-7654321
• License: LCSW-12345, State of California
• Address: 100 Wellness Way, Suite 4, San Francisco, CA 94102
• Patient: Jordan Smith | DOB: 04/12/1990 | Member ID: XYZ987654321
• Insurance: Aetna | Group #: 00123456
• Date of Service: 03/15/2026
• CPT Code: 90837 (Psychotherapy, 60 min)
• Diagnosis: F41.1 — Generalized Anxiety Disorder
• POS: 11 (Office)
• Fee Charged: $200.00 | Paid: $200.00

Common Mistakes That Get Superbills Rejected

• Wrong or missing NPI — always verify against your NPPES record
• Name mismatch — spell the patient's name exactly as it appears on their insurance card
• Using an expired or invalid diagnosis code
• Bundling multiple sessions on one line item
• Omitting the taxonomy code (required by some payers)
• Forgetting the provider signature

How to Fill Out a Superbill Quickly

In a busy practice, filling out a superbill from scratch for every client is tedious and error-prone. Most therapists create a template in Word or Google Docs and update the session-specific fields each time. The problem is that templates go stale — fee schedules change, address registrations get updated, and it is easy to forget to update the CPT code when you run a shorter session than usual.

How Superbilled Helps

Superbilled generates insurance-compliant superbill PDFs in under 60 seconds. You set up your provider profile once — NPI, license, address, taxonomy code — and then just fill in the session details for each client. The PDF output is formatted exactly the way major insurers expect, reducing rejected claims and saving you time every week.
