What Is a Superbill? How It Works in Medical Billing

Written by acadmin | Jul 1, 2025 10:41:59 PM

When your practice doesn’t bill insurance directly, your patients still need a way to get reimbursed for their care. That’s where superbills come in. A superbill is a detailed summary of a patient visit that you provide to the patient, so they can submit it to their insurance for possible reimbursement.

Superbills are especially useful for private-pay practices, out-of-network providers, and those who want to simplify operations while still supporting their patients financially.

 What Is a Superbill?

A superbill is a one-page document used in medical billing that lists the services provided during a patient’s appointment. While it's not a bill or an insurance claim, it contains all the information needed by insurance companies to process a reimbursement request from the patient.

It typically includes the patient’s diagnosis codes (ICD-10 codes), procedural codes (CPT codes), the provider’s contact information and credentials, and the dates and types of health services provided. The patient submits the superbill to their insurance provider, who reviews it and, depending on the patient’s insurance plan, may reimburse them for some or all of the out-of-pocket expenses.

Think of it as a bridge between clinical care and insurance. It lets your patient take the next step without adding more work to your team's plate.

Who Typically Uses Superbills?

Superbills are commonly used by providers who don’t directly submit claims to insurance, including:

  • Independent practices that are not in network with insurance companies
  • Direct primary care and concierge medicine offices
  • Specialists or therapists who operate on a cash-pay basis
  • Mental health providers, chiropractors, or specialists not credentialed with specific payers
  • Any provider who sees private-pay patients but wants to help them get reimbursed

What Information Is Included in a Superbill?

A well-prepared superbill contains all the data that insurance companies need to evaluate a patient’s claim. Below is a breakdown of both required and optional elements commonly included during superbill creation.

Standard Fields to Include:
  • Patient’s full name and date of birth
  • Provider’s name, practice name, NPI, address, and phone number
  • Date(s) of service
  • CPT codes for each procedure or service
  • ICD-10 codes for each diagnosis
  • Provider signature or official stamp
Optional but Helpful Fields:
  • Provider’s Tax ID or billing details
  • Fees charged for each service (this is helpful for the insurance reimbursement process)
  • Place of service codes (e.g., office visit, telehealth)
  • Referring provider, if applicable

Including this relevant information helps avoid delays in processing and increases the likelihood of a successful out-of-network claim.

What Is Not Documented in a Superbill?

While superbills contain many details about the visit, some items are deliberately excluded or must be handled elsewhere in the billing process:

  • The patient’s insurance plan or insurance company name
  • Whether services were covered or required prior authorization
  • Whether the patient has already paid (payment status)
  • An Explanation of Benefits (EOB). This comes later from the insurance provider

This is why patients must review their insurance coverage and out-of-network benefits before submitting the superbill.

What Is Not Included in a Superbill?

 

 

From Visit to Reimbursement

Here’s how the process usually works:

  1. After the appointment, your team gives the patient a completed superbill.
  2. The patient fills out any necessary claim form from their insurance.
  3. They send the form and the superbill to their insurer.
  4. The insurance provider evaluates the claim, checking procedure codes, diagnostic codes, and coverage status.
  5. If approved, the insurance reimbursement is sent directly to the patient.
When a Superbill Replaces the Claim

For providers who are not part of an insurance network, a superbill often takes the place of a standard insurance claim. Instead of the provider submitting the claim directly, the patient uses the superbill to request reimbursement from their insurance plan. This allows practices to support patients financially without participating in complex billing processes.

This approach is common among providers who:

  • Choose to avoid the administrative burden of credentialing and insurance claim submission
  • Operate under direct-pay or membership-based care models
  • Regularly treat patients with out-of-network insurance coverage

How to Avoid Rejection from Insurance Companies

Even when a patient submits a superbill properly, the insurance claim can be denied. These are some of the most common causes:

Common Reasons Claims Are Denied
  • Incorrect or missing CPT or ICD-10 codes
  • Missing provider information, like NPI or phone number
  • Services not included under the patient’s insurance plan
  • Lack of documentation supporting medical necessity
  • Handwritten forms that are hard to read
Tips to Minimize the Risk of Denial
  1. Keep your code library up to date
  2. Use templates for common visits
  3. Have someone review the document before handing it to the patient
  4. Offer a short handout explaining how to submit it

Being proactive helps reduce patient frustration and limits back-and-forth with the insurance company.

How Do You Know if Insurance Will Reimburse a Superbill?

Reimbursement depends on the patient’s coverage. Some plans may offer partial reimbursement for out-of-network services, while others may not cover them at all.

Steps Patients (and Practices) Can Take
  • Call the insurance provider in advance to verify out-of-network benefits
  • Ask if the services require prior authorization
  • Request a pre-visit estimate or benefit check, when available
  • Understand how deductibles and out-of-pocket expenses will affect reimbursement
What Can You Do as a Provider

You can help patients set the right expectations. At check-in or check-out, you might:

  • Explain the reimbursement process and how superbills are used
  • Offer a clear breakdown of procedural codes, fees, and services
  • Include any notes that might support insurance coverage (e.g., medical necessity)

Patients who feel supported during this process are more likely to return and refer others, even when you’re an out-of-network provider.

Is a superbill the same as an invoice?

No, a superbill is not the same as an invoice. While an invoice is a request for payment or a receipt showing payment made, a superbill is a detailed summary of the clinical care provided.  It includes diagnosis codes, procedure descriptions, provider details, and service dates, information needed by insurance companies to evaluate a reimbursement request.

An invoice is about money exchanged, while a superbill is about the medical services delivered.

Do I need a superbill if I have already submitted claims?

Generally, no. If your practice is submitting claims directly to insurance companies, the patient doesn’t need a superbill for reimbursement. However, there are still situations where one might be useful. A patient may request a superbill for their personal records, to coordinate benefits with secondary insurance, or if they plan to file an out-of-network claim on their own.

Can I create a superbill with my EHR system?

Yes. Systems like Amazing Charts allow you to auto-generate superbills directly from the visit documentation. This makes it easier to capture the correct CPT codes, ICD-10 codes, and other required fields.

What happens if a superbill has errors?

If a superbill contains incorrect codes or missing information, it can lead to claim denials or delayed reimbursement for the patient. This often results in confusion, additional phone calls, and frustration for everyone involved. That’s why it’s important to review each superbill for accuracy before handing it to the patient. A quick check for correct codes, complete provider info, and legibility can go a long way in avoiding preventable issues down the road.

Tips for Creating Accurate, Useful Superbills

#1 Keep Your Codes Updated

Always use the most current CPT and ICD-10 codes. Conduct annual code reviews with your billing team to stay up to date.

#2 Create Templates for Common Visits

Set up pre-filled templates for routine visit types (e.g., wellness exams, minor injuries). This saves time, improves consistency, and reduces documentation errors.

#2 Train Your Staff

Ensure front-desk and billing staff understand the components of a complete superbill. Well-informed staff can better support patients and answer questions about the process.
