Most behavioral health intake teams verify eligibility. Fewer actually verify benefits. That gap — between knowing a patient has insurance and knowing what it actually covers — is where the majority of preventable denials come from.
This is the checklist your intake team needs to run on every admission, with the specific questions to ask payers and the documentation to keep on file.
Eligibility Verification vs. Benefits Verification: What Is the Difference?
Eligibility verification confirms that a patient's insurance policy is currently active. Benefits verification goes further — it identifies what specific services are covered, at what cost-sharing levels, whether behavioral health is managed by a separate carve-out administrator, and whether prior authorization is required before the first service date. Both are required. One without the other is where most intake teams lose revenue.
Active coverage does not mean the recommended level of care is covered. It does not mean behavioral health benefits are managed by the plan you called. It does not mean prior authorization is not required before the first appointment. Assuming otherwise is the most common intake mistake in the industry.
#1 Check for a Behavioral Health Carve-Out Before Anything Else
A behavioral health carve-out is an arrangement in which a health plan contracts its mental health and substance use benefits to a separate third-party administrator — commonly Optum, Magellan, or Carelon — who manages authorizations, claims, and appeals independently from the primary medical plan. Many major commercial insurers, including UnitedHealthcare, Cigna, and Aetna, use this structure.
If you verify benefits through the medical plan and bill there too, the claim denies. Worse, these are often hard denials — you cannot correct and resubmit to the original payer, and the carve-out administrator's timely filing window may have already closed by the time you figure out what happened.

Ask the representative directly: "Are behavioral health benefits managed by this plan, or are they administered by a third party?" Get the name and phone number of that administrator before you end the call.
#3 Verify Coverage by Level of Care — Not Just "Mental Health"
Asking "do you cover mental health?" will get you a yes. That yes is useless. What you need to know is whether the specific level of care you are providing is covered under this plan, for this patient, starting now.
Ask separately about each service that may be part of the treatment plan:
- Outpatient therapy (individual, group, family)
- Medication management and psychiatric services
- Intensive outpatient (IOP) — typically 9+ hours per week
- Partial hospitalization (PHP) — typically 15+ hours per week
- Residential treatment
- Medical detoxification
- Medication-assisted treatment (MAT), including which medications require prior authorization
For each level, confirm: is it covered, is it in-network at your facility, does it require prior authorization, and are there day or session limits?
#4 Get the Cost-Sharing Numbers
For every admission, confirm the following before the patient arrives:
- Deductible amount and how much has been met year-to-date
- Copay or coinsurance percentage for behavioral health services
- Out-of-pocket maximum and how much remains
- Whether deductibles and out-of-pocket maximums are shared with medical or tracked separately for behavioral health
This is also your financial counseling conversation. A patient who owes a $4,000 deductible before coverage kicks in needs to know that at intake, not after three weeks of treatment.
#5 Confirm Prior Authorization Requirements Before Day One
Prior authorization is required for most higher levels of care — residential treatment, PHP, IOP, and medical detox with the majority of commercial payers. Some payers also require authorization for outpatient therapy beyond a set session threshold, and many require separate authorization for MAT medications.
Authorization windows are short. Some payers approve only two weeks at a time. Missing a reauthorization deadline means services delivered after the authorization expires are denied, often retroactively.
At verification, confirm: which services require prior authorization, how to submit the request, what clinical documentation is required, and how long the authorization period covers. Then build a reauthorization trigger into your workflow before the first authorization expires — not the day it does.
#6 Ask the Right Questions on the Call
The quality of your verification depends entirely on the questions you ask. Vague questions get vague answers that do not hold up when a claim denies three months later.
Before you end the call, make sure you have confirmed:
- The specific CPT codes you bill and whether they are covered (90791, 90834, 90837, 90847 for outpatient; H0015, H2036 for IOP)
- In-network status at your specific facility address
- Whether the policy covers co-occurring mental health and substance use treatment in the same program
- Session or day limits — and whether additional sessions can be authorized upon medical necessity review
- Any step-down requirements (e.g., must transition from PHP to IOP after a defined period)
Document the representative's name, the date of the call, and the reference number. That reference number is your only proof of what you were told if a payer later claims the information was incorrect.
#7 Know the MHPAEA Baseline
The Mental Health Parity and Addiction Equity Act requires that behavioral health benefits not be more restrictive than comparable medical or surgical benefits. If a plan imposes session limits, prior authorization requirements, or network restrictions on behavioral health that do not apply to equivalent medical services, that may be a parity violation.
The 2024 Final Rule strengthened enforcement of these requirements, with applicability for most plan years beginning January 1, 2025. If a payer's behavioral health limitations seem unusually restrictive, it is worth a parity review before writing off the denial.
#8 Oregon OHP: What Is Different
For Oregon Health Plan patients, the verification process has a few specific steps:
- Verify eligibility through the Provider Portal at or-medicaid.gov using the member's name and date of birth — the portal shows up to 13 months of historical eligibility data
- OHP does not require a referral for substance use or mental health services — patients can come directly to your program
- Most OHP members are enrolled in a Coordinated Care Organization (CCO) that manages physical, dental, and behavioral health together — for authorization, contact the member's CCO, not OHA directly
- For fee-for-service OHA authorizations (members not enrolled in a CCO), submit requests to OR1915i@kepro.com
- Effective July 1, 2021, some behavioral health codes no longer require prior authorization for participating providers — confirm current requirements by CCO
Verify Early, Document Everything, Build It Into Your System
Verification done the morning of the first appointment is too late. By that point, a patient has already shown up, expectations have been set, and the administrative options narrow. Verify 48 to 72 hours before the first service and build a structured checklist into your intake workflow so nothing gets skipped under time pressure.
If your program is experiencing a pattern of front-end denials — eligibility errors, carve-out misroutes, missing authorizations — the problem is almost always a workflow gap, not a staff problem. Saint Health works with behavioral health programs to build intake and verification systems that catch these issues before they become denials.
