How to Verify Out-of-Network Benefits for Therapy Clients
A practical, step-by-step guide for therapists to verify a client's OON mental health benefits before the first session — including the exact questions to ask.

One of the most valuable things you can do for a prospective therapy client is verify their out-of-network benefits before the first session. Clients who understand their coverage up front are more likely to commit to treatment — and less likely to be blindsided by unexpected costs.
Why Verify Benefits Before the First Session?
Many clients assume they have out-of-network coverage when they do not. Others have OON benefits but do not know their deductible or coinsurance rate. A benefits verification call takes about 15 minutes and gives both you and your client clarity on:
- Whether OON mental health benefits exist on the plan
- The OON deductible and how much has been met year-to-date
- The coinsurance rate after the deductible (e.g., insurer pays 60%, client pays 40%)
- The OON out-of-pocket maximum
- Whether prior authorization is required
- The plan's allowed amount for your typical CPT codes
Step 1: Ask for Insurance Information at Intake
Your intake paperwork should ask clients to provide their insurance company name, member ID, group number, and the primary policy holder's information. Ask them to photograph both sides of their insurance card and send it securely before the first session.
Step 2: Find the Member Services Number
The member services number is on the back of the insurance card. You will call this number as a provider calling on behalf of a patient. Have the client's member ID, date of birth, and name ready before you call.
Step 3: Ask the Right Questions
When you reach a representative, identify yourself as a mental health provider calling to verify OON benefits for a member. Then ask:
- Does this plan include out-of-network mental health benefits?
- What is the OON deductible for individual coverage? How much has been satisfied?
- What is the OON coinsurance rate after the deductible is met?
- What is the OON out-of-pocket maximum?
- Is prior authorization required for outpatient mental health services?
- What is the allowed amount for CPT code 90837 in my zip code?
- What is the timely filing limit for OON claims?
Write down the representative's name and the reference number for the call. If there is ever a dispute about what you were told, this documentation protects you.
Step 4: Check for Mental Health Parity
Under federal mental health parity law, most commercial plans must cover mental health services at parity with medical/surgical benefits. If a rep tells you that mental health is subject to a higher deductible or lower reimbursement rate than other services, that may be a parity violation worth escalating. Parity violations are more common than most clients and providers realize.
Step 5: Share the Information With Your Client
After the call, summarize what you learned in a simple, plain-language email or handout. Something like: "Your plan has a $1,500 OON deductible. You have met $400 so far this year. Once you meet the full deductible, your insurer will pay 60% of their allowed amount for sessions. Based on their allowed amount for your area, you could expect to receive approximately $XX back per session."
Be clear that these are estimates and that you cannot guarantee what the insurer will pay. Direct your client to their plan documents and member services for confirmation.
Step 6: Document Everything
Keep a record of the benefits verification in the client's file. Note the date, who you spoke with, the reference number, and the key figures. If the insurer later processes a claim differently than what was verified, this documentation gives your client leverage in an appeal.
When Verification Is Not Possible
Some clients prefer to verify their own benefits directly. You can give them the list of questions above and ask them to call member services themselves. Many insurer member portals also show OON benefit details without requiring a phone call — though the online figures are sometimes less complete than what you can get from a rep.
How Superbilled Helps
Once you have verified benefits and the client is ready to submit claims, Superbilled makes generating the required superbill documentation fast and accurate. Every field the insurer needs — NPI, taxonomy code, CPT code, ICD-10 diagnosis — is populated correctly so the client's claim does not get rejected on a technicality.
