Priya, a 29-year-old elementary school teacher in Minneapolis, started seeing an out-of-network EMDR therapist last September after a near-miss car accident left her with intrusive flashbacks and panic attacks at red lights. The therapist charged $190 a session, did not bill insurance directly, and handed Priya a single sheet of paper at the end of every month called a superbill. For the first three months, Priya stuck the superbills in a desk drawer because she did not understand what she was supposed to do with them. In December her sister, a medical biller in Chicago, looked at the stack and made one phone call and walked Priya through the carrier portal. Six weeks later, $1,420 hit Priya’s checking account as out-of-network reimbursement. She had paid $2,280 out of pocket across twelve sessions, and her plan reimbursed her at 70 percent of the allowed amount after she met her OON deductible. The superbills had been sitting unused, worth more than two months of her grocery budget.
A superbill reimbursement is the most common path American therapy clients use to recover money from out-of-network sessions, and it is also the path most people quietly abandon because the paperwork looks intimidating. The truth is that most superbills are nine lines long, the carrier portals accept them in PDF or photograph form, and a clean submission gets paid in 30 to 60 days about 80 percent of the time on the first try.
This guide walks through what a superbill is, exactly which fields the insurer needs, the standard CPT codes for therapy and intake, the reimbursement timeline, why claims get denied, the apps that automate submission, and when to escalate to your state insurance commissioner if a carrier refuses to pay.
What a superbill actually is
A superbill is an itemized receipt for the services you received. It is not a bill you owe, despite the name. You have already paid the therapist. The superbill is a document you submit to your insurer to request reimbursement under the out-of-network benefit on your plan. It is essentially a translation layer between your therapist’s invoice and the medical billing language insurers require.
The minimum fields a clean superbill includes are the therapist’s full legal name, license type, NPI number, tax ID or EIN, practice address, your name and date of birth, the date of service, the CPT code for the service, the ICD-10 diagnosis code, the fee charged, and a statement that the fee was paid. Some superbills include a place of service code (11 for office, 02 for telehealth) and the duration of the session. A monthly superbill that lists four sessions on one page is acceptable for most carriers. A separate superbill for each session is also fine.
The CPT codes you will see most often
Mental health services use a tight set of CPT codes that have not changed much in years. Memorize the five that cover almost everything.
- 90791 is the diagnostic intake interview, billed once at the start of treatment.
- 90837 is individual psychotherapy for 60 minutes, the most commonly billed code for weekly therapy.
- 90834 is individual psychotherapy for 45 minutes.
- 90832 is individual psychotherapy for 30 minutes.
- 90847 is family or couples therapy with the patient present.
- 90846 is family therapy without the patient present.
For psychiatry, you will see 99213, 99214, and 99215 for medication management visits at increasing complexity. For group therapy, 90853 is the standard code. The fee allowed for each code is set by your plan, not by the therapist, and is sometimes called the usual customary and reasonable rate or UCR. Your reimbursement is calculated against the allowed amount, not against the full fee charged.
Submitting an out-of-network claim
Every major carrier has a member portal with a section called something like Submit a Claim or Out-of-Network Claim. You upload the superbill as a PDF or photo, fill in your member ID and the date of service, and certify that the services were received. Some carriers still require a paper claim form, often called a HCFA 1500 or its newer cousin the CMS 1500. Most have moved to a simple online form that asks for the same information.
If your therapist is willing, ask them to fill out a CMS 1500 for you. Many will. The CMS 1500 includes everything an insurer wants to see in the format insurers prefer, and submission speeds up substantially. Our piece on out-of-network reimbursement strategies covers what to do when your plan has no OON benefit at all.
The 30, 60, and 90 day reimbursement timelines
Federal law requires insurers to acknowledge receipt of a clean claim within 30 days for most plan types and to pay or deny within 60 days. State laws often add prompt-pay rules with shorter windows. Reality follows the rules about 70 percent of the time. The other 30 percent is delays, requests for additional information, or denials that require appeal.
If you submit a clean superbill on January 5, expect an explanation of benefits in your portal by February 5, a check or direct deposit by March 5. If nothing has appeared by day 45, log a written follow-up through the portal so you have a paper trail. Reference the claim number from the original submission. Carriers stall less when there is documentation that you are tracking the timeline.
Why claims get denied and how to fix them
Most denials fall into one of five buckets, and most are fixable.
- Missing diagnosis code: the insurer cannot process a behavioral health claim without an ICD-10 code. Ask your therapist to add it. F33.1 (recurrent moderate depressive disorder), F41.1 (generalized anxiety), and F43.10 (PTSD unspecified) are common.
- Not pre-authorized: some plans require prior authorization for OON care or for certain CPT codes. Call before the next session and request authorization.
- Out-of-network referral missing: HMOs sometimes require a primary care referral for OON benefits to apply.
- Therapist NPI not registered: your therapist must have a Type 1 NPI listed in the National Plan and Provider Enumeration System. Most do, but new graduates sometimes file claims before their NPI is fully active.
- No OON benefit on the plan: HMOs and EPOs often have no OON coverage at all except for emergencies.
Read the EOB carefully. The denial reason code in the lower right of the EOB explains why and what your appeal rights are. The U.S. Department of Labor publishes a helpful guide to appealing employer-plan denials under ERISA. For state-regulated plans, your state insurance department handles parallel appeals.
Tracking reimbursement across a year
Build a simple spreadsheet with seven columns: date of service, CPT code, fee paid, date submitted, claim number, EOB date, amount reimbursed. Update it within a week of every session. The accumulating total tells you exactly how close you are to the OON deductible and OOP max, which most carrier portals display poorly or not at all.
Save every superbill, every CMS 1500, and every EOB as a PDF in a single folder. If you switch jobs or plans mid-year, you may need to submit older claims to the prior carrier and the records get tangled fast. The Centers for Medicare and Medicaid Services publishes claim-form standards, and following them keeps you compliant with all major carriers.
Reimbursify, Mentaya, and other apps that automate the work
The submission process is repetitive enough that several startups have built apps to automate it. Reimbursify lets you scan a superbill with your phone and submits the claim to your carrier on your behalf, charging a few dollars per claim. Mentaya partners with therapists who hand you a code at checkout, and the app pulls superbills from the practice management system automatically. Theramind, Better, and Sondermind have similar offerings on the provider side.
For therapy clients with weekly sessions, the time savings are real. The downside is a small fee per claim and the loss of direct visibility into the carrier portal. If your plan denies a claim, you still need to handle the appeal yourself or work through the app’s customer service. Superbill reimbursement apps are best treated as a convenience layer, not as a replacement for understanding your benefit.

When and how to escalate to the insurance commissioner
If a carrier denies a clean claim and the internal appeals fail, your next stop is your state insurance commissioner or department of insurance. File a complaint online with the carrier name, the policy number, the claim numbers, the dates, and the amounts. Attach the EOBs and your appeals correspondence. The commissioner’s office will open a complaint file and require the carrier to respond, usually within 21 to 30 days.
This works surprisingly often, especially for parity-related denials where the carrier appears to apply stricter rules to mental health than to medical care. ERISA-governed self-funded employer plans are technically outside state jurisdiction, but a complaint to the U.S. Department of Labor’s Employee Benefits Security Administration plays the same role for those plans. Carriers settle these complaints faster than they settle internal appeals because each commissioner complaint is tracked publicly. Our piece on getting OON coverage without a PPO covers what to do when your plan structure makes reimbursement nearly impossible.
What to ask your therapist before the first session
If you are starting with an OON therapist, two questions front-load the entire superbill reimbursement process. First, will you provide a monthly superbill with my diagnosis code, your NPI, and your tax ID? Second, are you willing to fill out a CMS 1500 if my insurer requires one? A yes to both means your administrative burden is minimal. A no to either means budget for more time on the phone with your carrier.
Some therapists outsource superbill generation to a billing service like SimplePractice, TherapyNotes, or Headway. The output is identical, often cleaner. A therapist who refuses to assign a diagnosis code is a red flag for reimbursement, because no diagnosis means no claim. Some clients prefer that for privacy reasons and pay full out of pocket as a deliberate trade.
Frequently asked questions
How long do I have to submit a superbill after the date of service?
Most carriers allow 90 days to one year for timely filing. Check your plan documents. Submit promptly to avoid an avoidable denial.
Will my employer see my diagnosis code if I submit a superbill?
No. The claim is processed by the insurer and is protected under HIPAA. Your employer sees aggregate claims data, not individual diagnoses.
Can I submit superbills for telehealth therapy?
Yes. Use place of service code 02 or 10 depending on the therapist’s location, and the same CPT codes apply. Most carriers reimburse telehealth at the same rate as in-person.
What if my therapist refuses to provide a diagnosis code?
You cannot submit a reimbursement claim without one. Discuss the implications with the therapist or consider switching to a provider who will assign one.
Does Medicare reimburse OON therapy via superbill?
Traditional Medicare allows assignment for participating providers and limited reimbursement for non-participating ones. Medicare Advantage plans rarely cover OON therapy outside of emergencies.
The bottom line
Superbill reimbursement recovers thousands of dollars for therapy clients every year, but only when the paperwork actually gets submitted. A clean superbill includes the therapist’s NPI, your diagnosis code, the right CPT code, and the fee paid. Submit through your carrier portal within 30 days of the session, track the claim in a spreadsheet, escalate to the insurance commissioner if a clean claim is denied, and consider apps like Reimbursify or Mentaya if the workflow is overwhelming.
