Why a Behavioral Health Budget Runs Out Before the Population Does

A benefit is sized in dollars and spent in hours. The conversion rate between the two decides how many people get care.

Plan design conversations happen in PEPM. Delivery happens in hours of somebody's time. Between those two numbers sits a conversion rate that rarely gets examined during renewal, and it sets how much of a covered population can actually receive something.

A behavioral health budget buys a finite quantity of care hours. Raise the cost per hour and the quantity falls. Route everyone to the most expensive hour available and the budget is consumed by a small share of the eligible population, most of whom were not the people in most distress.

The therapist shortage behind behavioral health access

Unit cost is not the only constraint, and in behavioral health it may not be the binding one.

In the APA's 2025 Practitioner Pulse Survey, which drew 1,742 completed responses from licensed, practicing psychologists, 38% reported accepting no form of health insurance. Among the reasons given for staying out of networks or leaving them, insufficient reimbursement led at 75%, followed by administrative issues with payers at 57% and concerns about payment reliability at 43%. Of the psychologists who did accept insurance, 10% had dropped a private or commercial panel within the past year.

APA characterizes network participation as little changed from 2024, so this is a standing feature of the market rather than a sudden shift.

Supply is the harder number. In the same survey, 46% of psychologists reported having no openings for new patients, and 40% were running a waitlist.

That produces a situation employers keep running into. A plan can raise its behavioral health budget and see very little change in how quickly members are seen, because the added dollars are competing for clinician hours that are already spoken for. Adding money to a supply-constrained market moves prices before it moves appointments.

Directory counts do not resolve this. A network can list clinicians who are not taking new patients, and the member experience is a run of unreturned calls regardless of what the adequacy report shows.

How coaching changes the cost per member reached

Coaching delivered by National Board Certified coaches draws on a different labor pool than licensed clinical practice. The training pipeline is shorter and the hour costs less to deliver. Supply is also not rationed by the same shortage.

For a benefits budget, that changes the arithmetic. The same dollars convert into more hours, and more of the eligible population can be reached with something structured rather than placed on a list. Wave's stepped care approach is built to route members by what they need rather than by what is available.

Whether those hours are worth buying is a separate matter, and it turns on outcomes rather than volume. In the JMIR study (Pickover and Adler, 2025), coaching produced statistically significant greater symptom reduction than an app-only control across all three DASS-21 domains in a cohort of 64, and the effects held in sensitivity analyses limited to participants with elevated symptoms at intake. More than half of that cohort presented with severe or extremely severe depression, anxiety, or stress. Separately, in Wave's internal book-of-business measurement, 72% of engaged members show clinically meaningful symptom improvement within eight weeks.

Those are two different bodies of evidence and they should be read separately. The published study is small and controlled. The internal figure is operational measurement across Wave's member population, and our auditable outcomes post sets out the methodology behind both.

Where coaching does not substitute for clinical care

Coaching does not replace licensed clinical care where licensed clinical care is indicated. Wave coaches do not diagnose and do not manage a care plan. When a member's measurement data or presentation indicates a higher level of care, Wave's care team routes through the partner network or the member's existing providers.

A benefit built entirely on coaching would fail the members who need psychiatry, intensive outpatient, or crisis services. The argument here is about what fills the front of the system, not about removing the rest of it.

Nor does a cheaper unit of care produce a medical spend reduction on its own. Behavioral health symptoms can interfere with how people manage chronic conditions, and avoidance and low activation show up in missed appointments and abandoned regimens. Those are plausible pathways, and they are not the same thing as a demonstrated change in claims. Wave does not claim a dollar figure it has not measured, and any vendor offering one should be asked which study produced it.

Questions to ask at your behavioral health renewal

Ask a vendor what the budget converts into. Not what it costs per employee per month, but how many members can receive a structured course of care within it, and what happens to the member who arrives in month nine.

Then ask what the vendor does when clinician supply in a given market is exhausted, since in most US markets it will be. A benefit that has only one unit of care to sell has only one answer to that question, and it is a waitlist.
