Insurance Verification, Done Before the First Session
Insurance verification is the process of confirming, before a session, that a client's coverage is active and finding out what the plan will pay for behavioral health care.
MCM South Medical Billing Service verifies insurance and eligibility for psychotherapists and psychiatrists. Mental health benefits often sit under a separate set of rules, limits and vendors, so a generic eligibility check can miss what matters.
Who this is for
- Solo and group therapists who verify benefits by hand today
- Psychiatrists who need E/M and add-on coverage confirmed
- Office managers who handle new-client intake
- Practices that want clear client cost information before session one
What is insurance verification, and why does it matter?
Insurance verification confirms two things before a session: that the client's coverage is active (eligibility), and what the plan covers and what the client owes (benefits).
The federal standard for electronic eligibility and benefit inquiries is the ASC X12N 270/271 version 5010, in effect since January 1, 2012, with federally mandated operating rules from January 1, 2013 (CMS.gov, checked 10/1/26). The CAQH CORE operating rules set consistent infrastructure and data-content requirements for how plans and providers exchange coverage and benefit information (CAQH CORE, checked 10/1/26).
A verification is not a promise to pay. Payers say so on their own provider pages. For example, Blue Cross and Blue Shield of Oklahoma states that eligibility and benefit information is not a guarantee of payment, and that the benefit determination happens when the claim is processed (BCBS of Oklahoma, checked 10/1/26). Verify early, record what you were told, and expect the claim to be judged on its own.
Insurance verification protects the front end of your billing cycle. A coverage check before the first session removes one common cause of denied claims. Our Claim Denials & Appeals guide covers what happens when a claim is denied anyway.
What to verify for a mental health client
For behavioral health, verify active coverage, who manages the behavioral health benefit, the client's cost share, visit limits, prior authorization, telehealth coverage, and any second plan.
| Check | What it tells you |
|---|---|
| Active coverage | Whether the plan is in force on the date of service, and the subscriber and member details to put on the claim. |
| Behavioral health manager | Whether the plan pays mental health claims itself or routes them to a separate behavioral health organization. Ask the payer who manages the benefit. |
| Network status | Whether you are in-network or out-of-network for this plan. See our in-network vs out-of-network guide. |
| Deductible | The amount the client pays for covered services before the plan starts to pay (HealthCare.gov). |
| Copay and coinsurance | A copay is a fixed amount the client pays for a covered service after the deductible. Coinsurance is a percentage of the cost (copay, coinsurance). |
| Out-of-pocket maximum | The most the client pays for covered in-network services in a plan year. It does not include premiums, uncovered services or out-of-network care (HealthCare.gov). |
| Prior authorization | Approval the plan may require before a service so that it is covered (HealthCare.gov). |
| Session limits and telehealth | Whether the plan caps visits, and whether it covers the telehealth modality you use. Ask the payer, because plans differ. |
| Other coverage | Coordination of benefits decides who pays first when two plans cover the same claim (HealthCare.gov). |
Our glossary defines these terms: eligibility and authorization.
Insurance verification for mental health covers more than active coverage. Confirm the behavioral health benefit, the network status of the rendering provider, and any authorization requirement. See our Credentialing & Network Status guide for how network status affects payment.
Insurance verification in four steps
- 1. Collect the card and the factsGet the front and back of the insurance card, the subscriber's name and date of birth, and the client's relationship to the subscriber.
- 2. Check eligibility electronically or by phoneRun an electronic 270/271 inquiry through your system or clearinghouse, or call the payer's provider line for benefits the response does not show.
- 3. Confirm the behavioral health detailsAsk who manages behavioral health, whether you are in-network, the cost share, visit limits, prior authorization rules and telehealth coverage.
- 4. Record it and tell the client what to expectSave the date, the source and any reference number. Give the client a clear picture of their cost share, from the provider's side, before the first session.
Good insurance verification is documented. Record the date, who you spoke with or which portal you used, and the reference number if the payer gives one.
Verification differs by payer type and by state
Keep these separate. They often conflict, and none replaces the payer's own rules.
Private (commercial) plans
Benefits, visit limits, authorization rules and behavioral health vendors vary by plan, employer and state. Verify each client's plan, not the insurance company in general. Blue Cross and Blue Shield companies, for example, are independent licensees, and our private insurance guides cover them one at a time.
Medicare
Medicare's HIPAA Eligibility Transaction System (HETS) lets you check eligibility in real time through a 270 request and 271 response. You build or buy your own tool, and the MCARE Help Desk runs Monday to Friday, 7 am to 7 pm ET (CMS.gov, checked 10/1/26). To find a client's Medicare Beneficiary Identifier (MBI), ask for the card, use the Medicare Administrative Contractor's secure portal, or check a past remittance advice (CMS.gov). The portal lookup needs the client's name, date of birth and Social Security number. Medicare's Coordination of Benefits and Recovery program keeps records of other insurance that should pay first.
Medicaid and state rules
Each state runs its own Medicaid program, and many states route behavioral health through a separate managed behavioral health organization or fee-for-service, a design known as a carve-out (Center for Health Care Strategies, 2016, Medicaid context). Verify which entity manages the member's behavioral health, because it differs by state and can differ by plan. Never infer one state's structure from another. See our Medicaid HCPCS guide for state pages.
Parity and benefit limits
The U.S. Department of Labor says most plans cannot apply visit limits to mental health benefits that are more restrictive than those for medical and surgical benefits (DOL parity page, checked 10/1/26). On May 15, 2025, the federal agencies said they will not enforce the new provisions of the 2024 final parity rule while it is under review. The underlying parity statute and the 2013 rule remain in effect (DOL enforcement statement). If a visit limit looks tighter than the medical one, raise it with the plan. Consult counsel or a compliance officer where real money or legal exposure is involved.
Self-pay and uninsured clients
For uninsured and self-pay clients, federal No Surprises Act rules say providers usually must give a good faith estimate when the client asks for one or schedules services at least three business days ahead (CMS.gov, checked 10/1/26). Ask your attorney or compliance officer how that applies to your practice.
Insurance verification rules differ for commercial plans, Medicare and Medicaid, and Medicaid rules vary by state. Verify each payer's own requirements. Do not assume one plan's rules apply to another.
Psychotherapists and psychiatrists verify differently
Psychotherapists
Focus on session limits, prior authorization, cost share, telehealth coverage and whether the plan carves behavioral health out. See individual psychotherapy codes for what you are verifying coverage for.
Psychiatrists
Ask whether E/M visits and psychotherapy add-on codes are covered, and whether they are handled under the behavioral health manager or the medical plan. See E/M codes and add-on codes.
Insurance verification looks different for psychotherapists and psychiatrists. Therapy practices check psychotherapy benefits. Prescribers check evaluation and management (E/M) benefits. Our electronic claims submission page shows what happens next.

Insurance verification FAQ
What should I verify before a first session with a new therapy client?
Verify that coverage is active, who manages behavioral health benefits, whether you are in-network, the deductible, copay or coinsurance, visit limits, prior authorization rules, telehealth coverage and any second plan. Record the date and source of each answer.
Does a 271 eligibility response guarantee my claim will be paid?
No. Payers state that eligibility and benefit information is not a guarantee of payment. Blue Cross and Blue Shield of Oklahoma, for example, says the benefit determination is made when the claim is received. Treat verification as the best information available on the date you check it.
How do I find out whether behavioral health is carved out to a separate company?
Ask the payer who manages the client's mental health benefits. In Medicaid, many states carve behavioral health out of managed care and pay through a separate organization or fee-for-service, and the structure differs by state and plan. Do not assume.
How do I check Medicare eligibility and find a client's MBI?
Medicare's HETS system returns real-time eligibility through a 270 request and 271 response. To find an MBI, ask for the card, look it up in your Medicare Administrative Contractor's secure portal, or check a past remittance advice.
How do I handle verification when a client has two insurance plans?
Verify both plans, then confirm which one pays first. Coordination of benefits rules decide the order, and Medicare tracks other coverage through its Benefits Coordination and Recovery Center. Record both plans before the first claim is filed.
