The Behavioral Health Billing Disconnect

A patient walks into a therapist's office for their first session. The lighting is warm. The furniture is intentional. The intake process is careful, respectful, trauma-informed. The clinician spends 45 minutes building rapport, establishing safety, and earning a small measure of trust.

Two weeks later, that same patient receives a paper statement in the mail. It's printed in 10-point font on a form that looks like it was designed in 2003. The balance is confusing. There are codes they don't recognize. The payment options are: mail a check, call a phone number during business hours, or log into a portal they've never heard of.

Everything the clinical team built in that first session, the billing process quietly works to undo.

This is the behavioral health billing disconnect. And it is one of the most expensive, least examined problems in the specialty.

A Demand Surge With No Infrastructure to Match

Behavioral health has been through a historic surge in demand. In 2025, about 1 in 5 U.S. adults (20.6%, or 54.6 million people) had a mental illness in the past year, according to SAMHSA's National Survey on Drug Use and Health. Utilization of mental health services grew 38.8% among commercially insured adults between 2019 and 2022 alone, with telehealth driving the growth.

Access is still tight. In the American Psychological Association's 2025 Practitioner Pulse Survey, 46% of psychologists said they had no openings for new patients and 40% had a waitlist, even as their workloads appear to have eased since the early years of the pandemic.

For practices, this growth presents a paradox. Clinical demand is strong. Revenue opportunity is real. Yet many BH practices operate on thinner margins than their patient volume would suggest. The reason is structural, and it starts with how behavioral health billing differs from almost every other specialty.

The Out-of-Network Reality

Behavioral health care goes out of network far more often than medical care. A 2024 RTI International study of claims for more than 22 million people found that patients went out of network 3.5 times more often to see a behavioral health clinician than a medical or surgical clinician.

The reasons are well-documented. Reimbursement for in-network behavioral health care has lagged behind medical and surgical care: in the same study, in-network office visits paid medical and surgical clinicians 22% more, on average, than behavioral health clinicians. Many clinicians, particularly those in private practice or small group settings, have concluded that credentialing with insurers is not worth the administrative overhead and reduced rates. In the same APA survey, 38% of psychologists did not accept any form of health insurance, and among those who accepted none or had recently dropped a plan, the barriers cited most often were insufficient reimbursement (75%) and administrative issues with insurance payers (57%).

The practical result: patients bear more of the cost directly.

When a patient sees an out-of-network therapist, they may submit claims for reimbursement, but the upfront cost is theirs. Even in-network patients face rising cost-sharing. A third of workers with employer coverage are now enrolled in a high-deductible health plan (HDHP) with a savings option, and 34% are in a plan with a single-coverage deductible of $2,000 or more, according to KFF's 2025 Employer Health Benefits Survey. A patient with a $2,000 deductible may pay full price for therapy until that deductible is met.

Mental Health Parity: The Law That Hasn't Fully Arrived

The Mental Health Parity and Addiction Equity Act (MHPAEA) was signed into law in 2008. It generally requires health plans that cover mental health and substance use care to make that coverage no more restrictive than their medical and surgical coverage. In theory, this should have leveled the playing field.

In practice, enforcement has been inconsistent. In its 2022 report to Congress, the Department of Labor said that none of the parity analyses it had reviewed contained sufficient information when first submitted, and the limits it most often asked plans to justify were prior authorization requirements and network admission standards. A 2019 review by the U.S. Government Accountability Office concluded that "the extent of compliance with these requirements is unknown."

For patients, this means navigating coverage that looks adequate on paper but often creates barriers in practice. Surprise denials, retroactive coverage changes, and opaque out-of-pocket calculations are common. And each of these creates a billing event that the practice must then communicate to the patient.

Why Patient Responsibility Is Higher in BH

Combine the out-of-network reality, parity gaps, and HDHP growth, and the result shows up in what patients pay. In a KFF analysis, privately insured adults treated for depression or anxiety in 2021 spent almost twice as much out of pocket over the year, across all of their care, as enrollees not treated for a mental health diagnosis: $1,501 versus $863 on average.

Consider the contrast. A patient seeing a primary care physician for an office visit often pays a copay at the desk, and in KFF's 2025 employer survey the average primary care copay was $27. A patient visiting an orthopedist for a follow-up may owe a specialist copay, which averaged $45. These are single, predictable transactions.

A therapy patient, on the other hand, may owe a payment for every session, attend weekly, and accumulate balances across months. If they're out-of-network, they're managing reimbursement submissions on their own. If they're in-network but under a deductible, they're paying full rates with no clear signal from the practice about when their deductible will be met.

The billing relationship in behavioral health is not a single transaction. It's an ongoing financial relationship, often spanning months or years, with variable amounts, changing insurance situations, and far more emotional weight than a copay at a dermatology office.

The pattern intensifies at higher levels of care. Residential substance use treatment can require large payments up front: in a 2021 Health Affairs study, researchers posing as uninsured people seeking residential treatment for heroin use were asked for an average of $17,434 up front by for-profit programs and $5,712 by nonprofit programs. Care at that level is financed by some combination of insurance, the patient, and often the patient's family. Parents and spouses become payers. Balances span detox, residential, IOP, and outpatient phases, each billed on its own cadence. The billing relationship becomes a family financial project stretched across months of care transitions, at exactly the moment the family is under the most emotional strain.

The Clinical Cost of Billing Friction

Here is where the disconnect becomes most damaging. In few specialties does the financial relationship intersect so directly with the therapeutic relationship.

Cost already keeps many people from care. In SAMHSA's 2025 survey, 61.4% of adults who felt they needed mental health treatment but did not get it said they thought treatment would cost too much. When patients feel confused, surprised, or frustrated by their bills, it doesn't just affect collections. It can affect care itself.

A patient who is stressed about an accumulating balance may cancel sessions. A patient who receives a confusing bill may disengage from their provider rather than call to ask about it (calling to discuss money is itself an anxiety trigger for many BH patients). A patient who is sent to collections for a balance they didn't fully understand may never return to therapy.

In few other specialties does billing friction carry this kind of clinical consequence.

What the Disconnect Actually Looks Like

In practice, the billing disconnect manifests in predictable ways:

Paper Statements That Arrive Weeks Late

A patient attends a session. The claim is processed. The EOB arrives. The practice generates a statement. Weeks have passed. The patient may not remember the session date, the amount discussed, or the balance. They set the statement aside.

Portal Logins Nobody Uses

The practice invested in a patient portal. It requires account creation, password management, and navigation through a system designed for a hospital, not a four-person therapy practice. Patients who never set up an account ignore the balance or call the office to ask questions staff don't have time to answer.

Front Desk Payment Conversations

A patient arrives for their session. The front desk asks about an unpaid balance. The patient is about to discuss childhood trauma, marital conflict, or suicidal ideation. The timing could not be worse. The staff member is uncomfortable. The patient is uncomfortable. The conversation is rushed, ineffective, or avoided entirely.

Collections as the Default Outcome

Balances that were never effectively communicated eventually age past 90 days. The practice writes them off or sends them to collections. The patient receives a collections notice for a bill they barely understood. The therapeutic relationship is over.

This pattern repeats every day across the country. It is not the result of bad intentions. It is the result of billing infrastructure designed for a different type of healthcare.

The Scale of the Problem

Behavioral health care is delivered by a large and varied workforce. HRSA's 2025 behavioral health workforce brief counts about 154,000 mental health counselors, 109,000 substance abuse and behavioral disorder counselors, 104,000 psychologists with doctoral degrees, and 52,000 psychiatrists in 2023, among other professions.

Yet billing technology in behavioral health has not kept pace with the specialty's growth. Many practices still rely on paper statements to tell patients what they owe.

The gap is not because BH practices don't care about the patient experience. Much of the billing technology market has focused on larger, more transactional specialties. BH, with its smaller practices, recurring visits, and out-of-network complexity, has been underserved.

The Financial Weight of the Disconnect

The disconnect is not merely a patient experience problem. It has measurable financial consequences that compound over time.

Consider a hypothetical practice with 150 active patients, each generating an average of $60 in patient responsibility per session across 30 sessions per year. That is $270,000 in annual patient revenue to collect. If the practice collects 80% of it, $54,000 goes uncollected every year.

Not all of that shortfall comes from patients who cannot pay. In a nationally representative 2023 survey published in JAMA Health Forum, 46.6% of people whose household received a medical bill they could not afford or disagreed with said they could not afford it, and 30.4% said the bill seemed confusing; respondents could give more than one reason. As the next article in this series will detail, confusing statements, inaccessible portals, and poorly timed communications keep payable balances from getting paid. These are infrastructure problems that can masquerade as affordability problems.

Meanwhile, every attempt to collect through traditional channels has a cost of its own. By PatientPay's estimate, each mailed statement costs about $2.13: about $1.00 for the stamp, envelope, and four sheets of paper, and about $1.13 in staff time to print, stuff, and mail it. A stamp costs $0.82. The staff time is about three minutes a statement at the Bureau of Labor Statistics mean wage for billing and posting clerks, $22.66 an hour in May 2023. The three minutes come from Encore Rehabilitation, which recovered more than 3,800 staff hours a year when it stopped printing, stuffing, and mailing more than 6,000 statements a month.

In a specialty that bills every week, that cost repeats with every session. A patient billed by mail every week costs about $111 a year to bill, and on a $40 copay, a single statement costs about 5% of the payment. And the estimate is a floor: it leaves out benefits, toner, return envelopes, posting the payment, and the calls about statements that go unpaid.

The disconnect can also have a referral cost. Patients who have a negative billing experience may be less likely to recommend the practice, even when the clinical experience was excellent. In a specialty where word-of-mouth and therapist referrals bring in new patients, the billing experience is quietly shaping the top of the funnel.

What Modern Billing Infrastructure Actually Means

Closing the disconnect doesn't require a practice to overhaul its operations. It requires a shift in how patient balances are communicated and collected.

Modern billing infrastructure for behavioral health means:

• Text-based balance notifications that reach patients where they already are
• No-login payment experiences that eliminate portal fatigue and let patients pay in a few taps
• Autopay and payment plan options that match the recurring nature of therapy
• HSA/FSA acceptance that makes it easy for patients to use pre-tax dollars they've already set aside for healthcare
• Discreet communication that respects the privacy sensitivity of behavioral health treatment
• Multi-guarantor and family billing that lets the parents, spouses, and family members who actually fund treatment each receive and pay their share, which is essential in residential and substance use care
• Automatic reconciliation back to practice management systems, eliminating manual posting

These are not nice-to-haves. For a specialty where the billing relationship can affect care itself, they are infrastructure.

The Series Ahead

This is the first article in a seven-part series examining every dimension of the billing disconnect in behavioral health. The second article examines why patients fall behind on bills, and why affordability is only part of the answer. The third article breaks down the math of recurring small-balance billing and why it's especially expensive in BH.

From privacy considerations to HSA/FSA opportunities to the operational burden on front desk staff, this series will cover the full landscape. The final article will give you three numbers to diagnose whether your practice has a billing problem, and what to do about it.

Behavioral health has earned its moment. Demand is strong. Clinical innovation is accelerating. The billing experience should not be the weak link.

Where PatientPay Fits

PatientPay was built for exactly this disconnect: discreet text and email statements patients actually open, autopay and payment plans that match the recurring rhythm of treatment, multi-guarantor billing for the families who fund residential and substance use care, and payments that post back to your system automatically. The results are measurable: PatientPay customers see a 25% average increase in patient collections and a 90% reduction in cost-to-collect.
