Same Session, Same Insurer, 7x the Pay: The Black Box in Commercial Therapy Rates

If you booked the same therapist, for the same hour, on the same insurance plan, twice, you might assume the plan pays the same both times. It often doesn’t. For CPT code 90837, the standard 60-minute individual psychotherapy session, the median commercial negotiated rate is $147, and the rates run from $78 all the way to $542 (Trilliant Health, 2026 Behavioral Health Report). Same code, same hour of care, roughly a 7x gap between the floor and the ceiling.

Quick answer: Commercial insurers pay wildly different amounts for the identical therapy session, and no one on either side of the transaction can see why. For CPT 90837, negotiated rates span $78 to $542, median $147 (Trilliant Health, 2026). Trilliant found that even inside one carrier, UnitedHealthcare, negotiated rates for individual and group psychotherapy codes vary by up to 7x. There is no published rationale a clinician can predict or an employer can audit. That opacity is not an accident. It is doing a job.

The number that shouldn’t be possible

Let’s be clear about what 90837 is. It is not a menu of services. It is one code for one thing: an hour of psychotherapy with a licensed clinician. The work in the room does not change from a $78 session to a $542 session, and neither does the training behind it, the clinical standard, or the paperwork the clinician files afterward.

What changes is a number set in a private negotiation the clinician never sees and the patient’s employer never sees. Trilliant Health’s 2026 Behavioral Health Report, released in April, put a figure on the chaos: for its individual and group psychotherapy codes, UnitedHealthcare’s commercial negotiated rates vary by as much as 7x. Not across the whole fractured market of dozens of payers. Inside a single carrier.

In practice, a therapist can hold two contracts with the same insurance company, treat two people with the same diagnosis for the same length of time, and get paid amounts that aren’t close. She usually finds out which one she got when the explanation of benefits arrives, weeks later.

Opacity isn’t a bug. It’s the product.

A working market needs a price both sides can see. When you buy almost anything else, the number is on the tag before you commit, so you can compare and walk away. Commercial behavioral health strips that out. The rate is invisible to the person selling the care and un-auditable by the employer buying the coverage. Both operate blind.

Here is the part that took me years of running programs to say plainly: this is not a system that keeps failing to be transparent. It is a system that works because it isn’t. A rate no one can predict is a rate no one can contest. A clinician can’t negotiate against a number she can’t see, and a benefits manager can’t push back on pricing he was never shown. The uncertainty does the work an argument would otherwise have to do.

Ask who that serves: the party that sets the rate, controls when it’s revealed, and answers to neither the clinician nor the employer. You do not get a 7x range inside one carrier by accident. You get it because nothing forces the range to close.

What unpredictable pay does to a clinician’s brain

Put a behavioral-science lens on this, because “rates are low” is only half the story. The other half is that they are unknowable, and we treat an unknowable reward very differently from a low but reliable one.

We are wired for uncertainty aversion. Given a choice between a predictable payoff and a gamble with the same average value, most people take the sure thing and will accept less to get it. A therapist deciding whether to stay on a panel is running exactly that calculation. She is not comparing $147 to her private-pay rate; she is comparing “I can build a practice on this” to “I have no idea what any session will pay, when, or whether the payer will claw it back later.” You cannot make payroll on a coin flip.

The clinicians are voting with their caseloads. In the 2024 APA Practitioner Pulse Survey, more than a third of psychologists (34%) were not in-network with any form of insurance. Among those who never accepted insurance or recently stopped, 82% cited low reimbursement rates, 62% cited administrative burden like pre-authorization and audits, and 52% pointed to unreliable payments, including delays and refund demands (APA, December 2024). Read that last number again. More than half named the reliability of payment, not just its size. Unpredictability isn’t a footnote to the pay problem. It is the pay problem.

This is the mechanism that thins a network. Every clinician who leaves for cash-pay is one fewer name on the roster your card promises. The people who stay ration their insurance slots. And the patient who was told they had coverage discovers that “in-network” and “actually available” stopped being the same thing. We wrote more about why so many clinicians are walking in why behavioral health clinicians are leaving insurance panels.

The employer is flying just as blind

Clinicians aren’t the only ones kept in the dark. The employer writing the premium checks is too.

If you run benefits for a company, you bought a behavioral health network on the promise that it would be there when your people needed it. But the negotiated rate behind any single session is not a number you can readily pull up and audit, even though your dollars set it. What those premiums buy at the point of care, or why the same session pays one clinician $78 and another $542, stays a black box to you too.

That matters more every year, because demand is not slowing down. Behavioral health utilization is up 62.6% since 2018, and among adults with unmet mental health needs, 65.2% cite cost as a barrier (Trilliant Health, 2026). Your employees want care, cost is already the wall in front of them, and the network they were handed is being quietly hollowed out by the same opaque rates you can’t inspect. Low and unpredictable pay pushes clinicians off the panel, a thinner panel sends your people out of network or into cash-pay, and the coverage you bought looks broad on the spreadsheet and narrow in real life. If you’ve watched your EAP go unused, this is a cousin of that problem, a benefit that exists on paper and evaporates on contact, which we dug into in the 3% EAP utilization problem.

None of this shows up in a benefits brochure. It shows up when a stressed employee spends three weeks calling names on a list and pays out of pocket anyway.

What “covered” is actually worth

Covered was never the same as cared for. A card in a wallet is a promise, and the value of that promise depends entirely on whether a clinician can afford to answer it. When the rate behind the card is invisible to the therapist and un-auditable to the employer, the promise is only as good as a market no one is allowed to see. The within-plan pay gap, where the same insurer pays less for mental health than for medical care, is this problem’s sibling; we covered it in why therapy pays less than medical care on the same plan.

Fixing it isn’t complicated to describe. A clinician should be able to predict a rate before agreeing to it, an employer should be able to inspect what its premiums buy, and someone should be able to explain why the same hour pays $78 or $542. That is the baseline condition of every honest market that isn’t this one.

At Mental Wealth Solutions we keep coming back to a simple test. If a price can’t survive being looked at, the problem was never the looking. The 7x spread has been hiding in plain sight, inside a single carrier, in a report anyone can read. The next move is to stop treating it as weather and start treating it as a choice someone made.

FAQ

How much do commercial insurers pay for a 60-minute therapy session? For CPT code 90837, the standard 60-minute individual psychotherapy session, the median commercial negotiated rate is $147, but rates run from $78 to $542 (Trilliant Health, 2026 Behavioral Health Report). That is roughly a 7x spread from the floor to the ceiling for the identical service.

Why do therapy reimbursement rates vary so much for the same code? There is no published logic a clinician or a plan sponsor can inspect. Rates are set in private negotiations and delivered after the fact. Trilliant Health found that even within a single carrier, UnitedHealthcare, negotiated rates for individual and group psychotherapy codes vary by up to 7x (Trilliant Health, 2026).

Does unpredictable pay push therapists out of insurance networks? It is one of the top drivers. In the 2024 APA Practitioner Pulse Survey, among psychologists who never took insurance or recently stopped, 82% cited low reimbursement, 62% cited administrative burden, and 52% cited unreliable payments, including delays and refund demands. More than a third of psychologists (34%) were not in-network with any insurer (APA, December 2024).

Why can’t employers see what their behavioral health coverage actually pays? The negotiated rate behind any single session is not something a plan sponsor can readily audit, even though the employer is paying the premiums. Meanwhile demand keeps rising (behavioral health utilization is up 62.6% since 2018) and cost is cited by 65.2% of adults with unmet mental health needs (Trilliant Health, 2026). Employers buy coverage they cannot inspect.
