How to Get Reimbursed for Out-of-Network Therapy Insurance: The Definitive Guide (2026)

You found a therapist you actually connect with — someone who gets your clinical approach, has availability that works for you, and specializes in exactly what you're dealing with. The only problem? They're out of network with your insurance plan.

Before you write off the idea of using your insurance benefits, stop. Most clients (and even some clinicians) don't realize that out-of-network (OON) therapy reimbursement is a very real option — and with the right process, you can recover anywhere from 40% to 80% of your therapy costs, depending on your plan.

This guide walks through everything: how OON benefits work, how to submit for reimbursement, what your therapist needs to provide, and the documentation pitfalls that get claims denied. Whether you're a client trying to stretch your mental health dollars or a therapist helping your clients navigate reimbursement, this is the guide you've been looking for.

What Does "Out-of-Network" Actually Mean?

When a therapist is "in-network," they've signed a contract with your insurance company to accept a pre-negotiated rate. When they're "out-of-network," no such contract exists. You typically pay the therapist's full fee upfront — and then you (or your therapist, depending on the arrangement) submit a claim to your insurance company for partial reimbursement.

The amount you get back depends on:

Whether your plan has out-of-network mental health benefits at all
Your OON deductible (often separate from your in-network deductible)
Your OON coinsurance rate (e.g., insurance pays 70%, you pay 30% after deductible)
The plan's Usual, Customary, and Reasonable (UCR) rate for your zip code and service type
Whether the No Surprises Act and Mental Health Parity laws apply to your plan

Key insight: Under the Mental Health Parity and Addiction Equity Act (MHPAEA), most commercial insurers are required to cover mental health benefits at parity with medical/surgical benefits. If your plan reimburses 70% for an out-of-network cardiologist, they generally can't reimburse less for an out-of-network therapist.

Step 1: Verify Your Out-of-Network Benefits Before Your First Session

This is the step most people skip — and it's the most important one.

Call the member services number on the back of your insurance card and ask these specific questions:

Do I have out-of-network mental health benefits?
What is my OON deductible, and how much have I met so far?
What is my OON coinsurance rate for outpatient mental health (office visits)?
Is there an OON out-of-pocket maximum?
What is the reimbursement based on — UCR, a percentage of Medicare rates, or the provider's billed amount?
Do I need a referral or prior authorization for OON mental health services?
What is the timely filing deadline for OON claims? (Usually 90–365 days from date of service)
Where do I mail or submit OON claims?

Pro tip: Write down the representative's name, the date/time of your call, and the reference number. This documentation is gold if you ever need to appeal a denial.

Step 2: Understand How Reimbursement Is Actually Calculated

Here's where things get tricky. Insurance companies don't simply reimburse your therapist's full rate. They calculate reimbursement based on their own internal benchmark — the Usual, Customary, and Reasonable (UCR) rate — which is essentially what they've decided is the "going rate" for a given service in your geographic area.

A Real-World Example

Your therapist charges $200 per 55-minute session (CPT code 90837)
Your plan's UCR rate for 90837 in your zip code is $160
Your OON coinsurance is 70/30 (insurer pays 70%, you pay 30%)
Your OON deductible has already been met

Calculation:

Insurance applies coinsurance to the UCR: 70% × $160 = $112 reimbursed
You are responsible for: $200 (therapist fee) − $112 (reimbursement) = $88 out of pocket per session

This is why knowing the UCR rate matters. Some plans (especially HMOs and EPOs) have no OON benefits whatsoever, which is critical to confirm upfront.

Common CPT Codes for Outpatient Therapy Sessions

| CPT Code | Service Description | Typical Duration | |---|---|---| | 90837 | Individual psychotherapy | 60 minutes (53–60 min) | | 90834 | Individual psychotherapy | 45 minutes (38–52 min) | | 90832 | Individual psychotherapy | 30 minutes (16–37 min) | | 90847 | Family psychotherapy (with patient) | 50 minutes | | 90846 | Family psychotherapy (without patient) | 50 minutes | | 90853 | Group psychotherapy | Variable | | 90791 | Psychiatric diagnostic evaluation | 60–90 minutes | | 90792 | Psychiatric diagnostic evaluation with medical services | 60–90 minutes | | 99213/99214 | Medication management (E&M codes, used by psychiatrists) | 15–25 minutes |

Step 3: Get a Proper Superbill from Your Therapist

The superbill is your golden ticket to OON reimbursement. It's an itemized receipt that contains all the information your insurance company needs to process your claim. A superbill is not just a receipt — it's a clinical billing document with very specific required fields.

What a Complete Superbill Must Include

Provider's full name and credentials (e.g., Jane Smith, LCSW)
Provider's NPI number (National Provider Identifier — 10-digit number)
Provider's Tax ID (EIN or SSN)
Practice name and address
Provider's signature
Client's full name and date of birth
Client's insurance member ID and group number
Date(s) of service
CPT code(s) for each session
ICD-10 diagnosis code(s) (e.g., F33.1 for Major Depressive Disorder, moderate)
Place of service code (11 = office; 02 = telehealth)
Fee charged per session
Amount paid by client

If any of these fields are missing, your claim will likely be rejected or delayed. Ask your therapist to review their superbill template against this list.

Step 4: Submit Your Claim — Mail, Fax, or Online Portal

Once you have a complete superbill, it's time to submit. Most insurers accept claims in one of three ways:

Online member portal — The fastest option. Many large insurers (Aetna, Cigna, UnitedHealthcare, Anthem/BCBS) have online claim submission portals.
Mail — Print and complete a CMS-1500 claim form (the standard paper claim form), attach your superbill, and mail to the address on your insurance card's claims submission section.
Fax — Some insurers still accept faxed claims. Always keep a confirmation page.

Timely filing matters. Most plans require claims to be submitted within 90 to 180 days of the date of service. Some plans allow up to 365 days. If you miss the deadline, you lose your right to reimbursement — no exceptions, no appeals.

Step 5: Track Your Claims and Follow Up

Claim tracking is where most people drop the ball. Here's a simple system:

Keep a spreadsheet with: date of service, CPT code, date submitted, claim reference number, expected reimbursement, and actual reimbursement received
Follow up with your insurer 14–21 days after submission if you haven't received an Explanation of Benefits (EOB)
When you receive your EOB, verify that the payment matches what you calculated — errors are common

What Happens When Your Claim Gets Denied?

Don't panic — and don't give up. First-pass denial rates for mental health claims run as high as 15–20% with some commercial payers. Most denials are fixable.

Common Denial Reasons and Fixes

| Denial Reason | What It Means | What To Do | |---|---|---| | Missing/invalid NPI | Provider NPI not on file or incorrect | Get correct NPI from your therapist; resubmit | | Diagnosis not covered | ICD-10 code not on covered diagnosis list | Ask therapist if alternate/additional dx applies; appeal | | Timely filing exceeded | Claim submitted too late | Appeal with proof of timely submission; rarely reversible | | Not medically necessary | Insurer questions clinical need | Request appeal with clinical notes/letter of necessity | | No OON benefits | Plan doesn't cover OON services | Verify plan type; consider external appeal or parity complaint | | Incorrect place of service | Wrong POS code (e.g., telehealth vs. office) | Resubmit with correct POS code (02 for telehealth, 11 for office) | | Duplicate claim | Insurer already has a claim for same DOS | Verify with insurer; avoid resubmitting without confirmation |

How to File an Appeal

Request the denial reason in writing (you're entitled to this)
Gather supporting documentation: the superbill, your EOB, a letter of medical necessity from your provider, and any clinical notes
Submit a formal written appeal referencing the MHPAEA and your plan's stated OON benefit
If the internal appeal fails, request an Independent Medical Review (IMR) or external review — most states mandate this option
File a complaint with your state insurance commissioner if parity violations are suspected

Major Insurers: OON Mental Health Reimbursement at a Glance

| Insurer | OON Mental Health Benefits? | Typical OON Coinsurance | Claims Portal | |---|---|---|---| | UnitedHealthcare | Yes (most PPO plans) | 50–70% after deductible | myuhc.com | | Aetna | Yes (most PPO plans) | 50–70% after deductible | aetna.com/member | | Cigna | Yes (most PPO plans) | 50–70% after deductible | mycigna.com | | Anthem/BCBS | Yes (most PPO plans) | 60–80% after deductible | anthem.com | | Humana | Limited (plan dependent) | 40–60% after deductible | humana.com | | Kaiser Permanente | Generally No (HMO only) | N/A — HMO model | N/A | | Oscar Health | Limited | Varies | hioscar.com | | Medicaid | Rarely | N/A | State-dependent |

Note: Always verify directly with your specific plan. OON benefits vary widely even within the same insurer based on your employer's plan design.

For Therapists: How to Set Up Your Practice for OON Client Success

If you're a therapist, psychiatrist, LCSW, LPC, or LMFT operating out-of-network, here's how you can make the reimbursement process as smooth as possible for your clients — and protect yourself clinically and legally.

1. Use a Complete, Accurate Superbill Template

Your superbill is a legal document. Errors or omissions don't just inconvenience your client — they can trigger payer audits and compliance issues. Make sure every required field (listed above) is populated for every client, every session.

2. Choose Diagnosis Codes Carefully

ICD-10 diagnosis codes must be clinically supported by your documentation. Don't upcycle a diagnosis to improve reimbursement odds — that's fraud. Do ensure that the diagnosis you're billing reflects your actual clinical assessment and is documented in your intake/evaluation notes.

3. Know Your CPT Code Nuances

90837 vs. 90834: The difference is session length. 90837 requires at least 53 minutes of face-to-face time. If you're consistently billing 90837 for 45-minute sessions, you're exposed to audit risk.
Telehealth: Use place of service 02 for telehealth sessions. Failure to do so can result in claim denial or recoupment.
Add-on codes: Codes like 90785 (interactive complexity) and 90839/90840 (crisis psychotherapy) can be appropriate in specific clinical situations — but document thoroughly.

4. Maintain Airtight Progress Notes

If a client's claim is audited, insurers can request clinical records. Your progress notes must support the CPT code billed, the diagnosis, and the medical necessity of ongoing treatment. The SOAP or DAP note format is widely accepted and defensible.

5. Educate Your Clients

Many clients don't know they have OON benefits. Walk new clients through the verification process, provide them with a well-structured superbill, and consider offering a brief "how to submit your claim" handout. This reduces no-shows and improves client retention because clients who are reimbursed stay in treatment longer.

Frequently Asked Questions (FAQ)

1. How long does it take to get reimbursed for out-of-network therapy?

Most insurers process OON claims within 14 to 30 days of receipt. If you submitted by mail, factor in an additional 7–10 days for delivery. Online portal submissions are typically processed fastest. If you haven't received an EOB within 30 days, call member services with your claim reference number.

2. Can my therapist submit the OON claim on my behalf?

Yes — this is called a courtesy billing or direct billing arrangement. However, because the therapist is out of network, any reimbursement will typically be sent to you, the member, not the provider (unless you've signed an Assignment of Benefits form). Some therapists do submit on behalf of clients as a client service, even if they don't accept assignment.

3. What is the difference between a superbill and a CMS-1500 form?

A superbill is an itemized receipt from your provider containing all the billing and diagnostic information. A CMS-1500 is the standard paper claim form used to submit that information to an insurer. Many payers accept a superbill directly; others require you to transfer the information onto a CMS-1500. Check with your specific insurer.

4. My plan says I have OON benefits, but the reimbursement was much lower than expected. Why?

This usually comes down to the insurer's UCR rate being significantly lower than your therapist's actual fee. Insurers set UCR rates independently, and they're not always transparent about how they're calculated. You can request the UCR rate in writing and, if you believe it's unreasonably low, file a MHPAEA parity complaint with your state insurance department or the U.S. Department of Labor (for employer-sponsored plans).

5. Does telehealth therapy qualify for OON reimbursement?

Yes — telehealth parity laws in most states require insurers to cover telehealth mental health services at the same rate as in-person services. However, make sure your therapist uses the correct place of service code (02) and, if required, a telehealth modifier (GT or 95) on the superbill or claim form. Some plans still have restrictions, so confirm with your insurer before your first session.

6. What if my employer's plan doesn't have OON benefits at all?

If your plan is an HMO or EPO, OON benefits are typically excluded except in emergencies. In this case, your options include: switching to a PPO plan during open enrollment, using a Flexible Spending Account (FSA) or Health Savings Account (HSA) to pay therapy costs pre-tax, or seeking in-network providers. You may also explore sliding scale fees with OON therapists who offer them.

7. Is there a limit to how many OON therapy sessions insurance will cover?

Technically, under MHPAEA, insurers cannot impose session limits on mental health services that they don't also impose on comparable medical services. However, insurers can and do apply medical necessity reviews after a certain number of sessions. This is where strong clinical documentation becomes critical — your therapist's progress notes need to demonstrate ongoing clinical need.

The Documentation Factor: Why Your Therapist's Notes Make or Break Your Reimbursement

Here's a truth that doesn't get discussed enough: the quality of your therapist's clinical documentation directly impacts your ability to get — and keep — your reimbursement.

If an insurer audits your claims (which happens more often than people think, especially after a certain utilization threshold), they'll request clinical records. If the notes don't match the billed codes, don't support the diagnosis, or lack documented medical necessity, the insurer can recoup months or years of reimbursements — from your therapist, but sometimes from you.

This is why documentation accuracy isn't just a billing issue. It's a protection issue for both clients and clinicians.
