Mental health parity on a VOB call: what MHPAEA requires and what to ask the payer

1. What parity requires

The rule (29 CFR 2590.712 for employer plans under ERISA; 45 CFR 146.136 for group plans and insurers under the Public Health Service Act) compares behavioral health benefits with medical and surgical benefits inside each of six classifications, never across them:

1. inpatient, in network
2. inpatient, out of network
3. outpatient, in network
4. outpatient, out of network
5. emergency care
6. prescription drugs

Outpatient may be split into office visits and all other outpatient services, and a plan with tiered networks may compare tier by tier. The plan has to assign behavioral health benefits to classifications using the same standards it uses for medical benefits, so where residential treatment, PHP and IOP land depends on where the plan puts comparable medical services. Then three kinds of limits are tested (CMS; CMS FAQs):

Kind of limit	Examples	The test
Financial requirements	Deductibles, copays, coinsurance, out-of-pocket maximums	Can't be more restrictive than the predominant level that applies to substantially all medical and surgical benefits in the classification. "Substantially all" means at least two-thirds; "predominant" means the level that applies to more than half. Deductibles and out-of-pocket maximums can't be kept separate for behavioral health.
Quantitative treatment limits	30 outpatient visits a year, 20 inpatient days a stay	Same predominant/substantially-all test. A visit cap on therapy that medical outpatient care in the same classification doesn't have generally fails.
Nonquantitative treatment limits (NQTLs)	Prior authorization and concurrent review, medical necessity criteria, fail-first rules, network admission standards, how out-of-network rates are set, facility-type or geographic limits	Allowed only if the processes, strategies, evidentiary standards and other factors used for behavioral health are comparable to, and applied no more stringently than, those used for medical care in the classification. Since the Consolidated Appropriations Act, 2021, plans must have written comparative analyses of their NQTLs.

Two disclosure rights you can use. A plan must make its criteria for medical necessity determinations for mental health and substance use benefits available on request to any current or potential participant, beneficiary or contracting provider, and it must make the reason for any denial available (29 CFR 2590.712(d)). The Department of Labor publishes a model form for requesting documents from an employer plan, and a guide to disclosure rights.

Parity doesn't require a plan to cover mental health or substance use treatment at all, or any particular diagnosis. It applies once the plan does. (Non-grandfathered individual and small-group plans must cover both as essential health benefits.)

2. Which plans it applies to

Plan	Federal parity?	Notes
Employer plan, more than 50 employees, fully insured	Yes	In Texas, a TDI-regulated plan also follows Texas parity law (below).
Employer plan, self-funded (ERISA)	Yes	State insurance law generally doesn't reach it, but federal parity does. The Department of Labor enforces it for private employers.
Self-funded state or local government plan	Yes, for nearly all now	These plans could once opt out. No new opt-outs after December 29, 2022, and existing ones generally couldn't be renewed if they expired on or after June 27, 2023; some collectively bargained plans kept theirs until the last agreement ends (CMS bulletin). HHS enforces for these plans.
Individual and Marketplace plans; small-group insurance	Yes (small group through the essential health benefit rules)	Small employer group plans (50 or fewer employees) are exempt from MHPAEA itself, but non-grandfathered small-group insurance must cover behavioral health as an essential health benefit, with parity.
Medicaid managed care (STAR, STAR+PLUS, STAR Kids, STAR Health) and CHIP	Yes, under Medicaid's own parity rules	Federal Medicaid and CHIP rules apply parity to managed care plans (Medicaid.gov); HHSC reports on Texas Medicaid and CHIP parity.
Medicare (Original and Medicare Advantage)	No	MHPAEA doesn't apply to Medicare. Medicare has its own rules, such as the 190-day lifetime limit on inpatient psychiatric hospital care (Medicare.gov).
Retiree-only plans	No	A plan that covers only retirees isn't subject to MHPAEA. A retiree on Medicare with a retiree plan has neither plan bound by it.

Self-funded vs fully insured is the question that decides which law and which regulator you're dealing with, so ask it on every commercial VOB. The card may say "TDI" or "DOI" for a state-regulated plan, but the rep is the better source (TDI).

3. The 2024 rule: where it stands

Date	What happened
September 9, 2024	The Departments of Labor, HHS and the Treasury issued the final rule "Requirements Related to the Mental Health Parity and Addiction Equity Act" (Federal Register, September 23, 2024). It amended the 2013 rule and added rules for NQTL comparative analyses.
January 1, 2025 and 2026	Group plans: generally plan years beginning on or after January 1, 2025, with some provisions, including the "meaningful benefits" standard and the prohibition on discriminatory factors, from January 1, 2026. Individual market: policy years beginning on or after January 1, 2026 (DOL).
January 17, 2025	The ERISA Industry Committee sued in federal court in Washington, D.C., challenging parts of the rule.
May 15, 2025	The Departments said they will not enforce the parts of the 2024 rule that are new compared with the 2013 rule, for failures before a final decision in that case plus 18 more months. They asked the court to pause the case while they reconsider the rule, possibly proposing to rescind or modify it. MHPAEA's statutory requirements, as amended by the Consolidated Appropriations Act, 2021, still apply (Departments' statement).
As of this update	We found no replacement rule published. Check the DOL parity page before you rely on this row.

What it means for your calls and appeals: lean on the statute and the 2013 rule (the classifications, the financial and visit-limit tests, comparable and no-more-stringent NQTLs, criteria and denial-reason disclosure) and on the comparative-analysis requirement from 2021. Don't build an appeal on the 2024 rule's new pieces, such as the meaningful benefits standard or its outcomes-data requirements, while they aren't being enforced.

4. Texas parity law

For plans regulated by the Texas Department of Insurance, House Bill 10 (85th Legislature, 2017) added parity requirements in Texas Insurance Code chapter 1355, subchapter F, and TDI's rules in 28 TAC chapter 21, subchapter P track the federal rule at 45 CFR 146.136 (TDI, parity rules; adopted rule). TDI's overview describes what the rule adds: insurers file parity data with TDI each year, and they must do compliance analyses of their quantitative and nonquantitative limits and provide them on request (TDI overview; coverage and parity).

• Fully insured Texas plan: federal parity and Texas parity; complaints to TDI.
• Self-funded employer plan: federal parity only; questions and complaints to the Department of Labor's Employee Benefits Security Administration.
• Texas Medicaid or CHIP plan: Medicaid's parity rules; help through the HHS Office of the Ombudsman's behavioral health help line.

Texas's prompt-pay and verification rules follow the same split: our guide to Texas verification and the guarantee of payment covers when a TDI-regulated plan must promise to pay.

5. Answers that should prompt a second question

None of these proves a violation; a rep can't tell you how the plan treats comparable medical care. Each one is worth a follow-up question and a note.

The rep says	Why it's worth a second question	Ask
"There's a separate deductible for behavioral health."	Deductibles and out-of-pocket maximums have to combine medical and behavioral health spending in a classification.	"Does medical spending count toward it, and does it count toward the medical deductible?"
"Outpatient therapy is limited to 20 visits a year."	A visit cap needs a matching cap on substantially all medical outpatient benefits in the same classification.	"Is there a visit limit on medical outpatient services like physical therapy or specialist visits? Can you note that the limit is on the behavioral health benefit?"
"There's no out-of-network benefit for mental health."	If the plan covers medical care out of network in that classification, it generally has to cover behavioral health there too.	"Does the plan have out-of-network medical outpatient benefits?"
"Residential treatment isn't covered."	Benefits are assigned to classifications by the same standards for both. If the plan covers comparable medical inpatient-level care, such as skilled nursing, ask how residential treatment is classified.	"Which classification does the plan put residential treatment in, and is skilled nursing or inpatient rehabilitation covered?"
"IOP needs prior authorization and review every 7 days."	Authorization and review frequency are NQTLs. They're allowed if they're comparable to how the plan manages medical care in the same classification.	"Which criteria are used for the review? How do we get a copy?" (The authorization itself is in the prior authorization guide.)
"The therapy copay is the specialist copay."	A copay level has to pass the predominant/substantially-all test against medical office visits in the classification.	"What copay applies to most medical office visits on this plan?"
"Mental health is handled by another company."	Carve-outs are allowed, but the combined plan still has to meet parity, and the carve-out's rules are part of it.	Get the carve-out's name and number and verify there (see behavioral health carve-outs).

6. The questions to ask, and what to write down

Add these to the call you already make. The full call, level by level, is in the VOB call script, and the VOB checklist lists everything else to verify before an admission.

1. "Is this plan fully insured or self-funded? Is it regulated by the Texas Department of Insurance?" Write down the answer and whether it's an employer, government, Marketplace, Medicaid or Medicare plan.
2. "Are there any visit, day or dollar limits on [therapy / IOP / PHP / residential]?" If yes, ask whether the same limit applies to medical outpatient or inpatient care.
3. "Is the deductible and out-of-pocket maximum shared with medical?" Note individual and family, and how much is left. Our guide to deductible vs out-of-pocket shows the math.
4. "Is prior authorization required, and how often is concurrent review?" Note the phone or portal, the first review date and the clinical information they want.
5. "Which medical necessity criteria does the plan use for this level of care, and how can we get a copy?" A contracting provider can ask for them under 29 CFR 2590.712(d); an out-of-network provider can help the client ask.
6. "Is any of this benefit managed by another company?" If yes, verify again there.
7. The rep's name, the date and time, and the call reference number. Without these the rest is hearsay.

Start with the electronic check: a limit often shows up in the 271 before you call. In our guide to reading a 271 eligibility response, a line like EB*F*IND*AI … VS*30 is a 30-visit limit on the substance use benefit.

7. A parity note for the VOB form

A made-up example of what the note on the printable VOB form looks like when something is worth flagging:

Plan: employer PPO, self-funded (rep confirmed; not TDI). SUD outpatient: 30-visit calendar-year limit shown on 271 and confirmed by rep. Rep didn't know of a visit limit on medical outpatient. IOP: auth required, concurrent review every 7 days. Criteria: plan's own; rep says request in writing through the provider portal. Deductible shared with medical, $1,250 of $2,000 met. Rep: J. Alvarez, 10/28/2026 2:14 pm, ref 55-0193. Flag for billing: visit limit (parity question).

Billing then knows, before visit 30, that the limit is coming and that a written request for the criteria and the plan's comparative analysis may be the next step.

8. When you think a denial breaks parity

1. Get the denial in writing and read the reason. Under ERISA claims rules the notice has to give the specific reason and the plan provision; our guide to reading an EOB shows where the reason codes are.
2. Ask for the criteria used for the decision, and ask the plan (with the client's authorization, for documents only the member can request) for its NQTL comparative analysis, using the DOL model form for employer plans.
3. Appeal on the merits first: medical necessity, with the clinical record and the criteria. Add the parity argument where the facts support it: the limit, the comparison, and what the plan's documents show. Our sister site has appeal letter templates and a guide to behavioral health claim denials.
4. Use external review after the internal appeal for plans that offer it.
5. Send a complaint to the right regulator for the plan's type: TDI, the Department of Labor, HHS, or HHSC for Medicaid and CHIP.

For a program that keeps hitting the same limit with the same payer, the fix is often at the contract level: the utilization review guide covers running reviews well, and a single-case agreement or network contract may settle it.

How Quick VOB helps

Quick VOB shows each level of care side by side (covered or not, authorization needed or not, cost and day limits) from the insurer's answer, flags carve-outs with their own check one tap away, and "Log the call" keeps the rep's answers on funding, limits and criteria with their name and reference number. When a visit limit or a separate deductible shows up, it's on the record before the first session.

Questions

What is the Mental Health Parity and Addiction Equity Act?

A federal law (MHPAEA) that says a health plan covering mental health or substance use treatment can't make it harder to use than medical and surgical care in the same class of benefits: financial requirements, visit and day limits, and rules like prior authorization and medical necessity criteria.

What is an NQTL in mental health parity?

A nonquantitative treatment limitation: a rule that limits the scope or duration of benefits without a number, such as prior authorization, concurrent review, medical necessity criteria, fail-first rules, network admission standards and how out-of-network rates are set. For behavioral health it must be comparable to, and applied no more stringently than, the same rule for medical care in the classification.

Does mental health parity apply to self-funded plans?

Yes. Self-funded employer plans generally aren't subject to state insurance law, but federal parity applies to them. Self-funded state and local government plans could once opt out; that option has ended for nearly all of them.

Does mental health parity apply to Medicare?

No. MHPAEA doesn't apply to Original Medicare or Medicare Advantage. Medicare has its own benefit rules, such as the 190-day lifetime limit on care in a psychiatric hospital.

Is the 2024 mental health parity rule in effect?

It was issued in September 2024, but on May 15, 2025 the Departments said they won't enforce its new provisions (compared with the 2013 rule) until a court case ends plus 18 months, while they reconsider the rule. The statute, the 2013 rule and the 2021 comparative-analysis requirement still apply.

Does Texas have a mental health parity law?

Yes, for plans regulated by the Texas Department of Insurance: Insurance Code chapter 1355, subchapter F (HB 10, 2017), with TDI rules in 28 TAC chapter 21, subchapter P. It doesn't reach self-funded employer plans, which follow the federal law.

Can a plan have a separate deductible for mental health?

Not under parity. Deductibles and out-of-pocket maximums must combine medical and behavioral health spending within a classification.

Can a plan require prior authorization for IOP?

Yes, if its authorization process for behavioral health is comparable to, and no more stringent than, its process for medical care in the same classification. Ask which criteria it uses and how often it reviews.
