Behavioral Health Billing Experts
Therapists and psychiatrists lose up to 25% of revenue to missed authorizations, carve-out routing errors, and uncaptured add-on codes. We handle the insurance bureaucracy — tracking every session limit, routing claims to the right MBHO, and fighting parity-law denials — so you can focus entirely on your patients.
Why Standard Billers Fail in Behavioral Health
Mental health billing is not a subset of medical billing — it is an entirely separate discipline. Behavioral health involves carve-out payers, time-based codes, session-level authorization tracking, and mental health parity law enforcement that most medical billing teams have never encountered.
A generalist biller who doesn't know that a patient's UHC benefits are managed by Optum Behavioral Health will submit every mental health claim to the wrong payer — generating a 100% denial rate on those claims. That's not a recoverable error. That's lost revenue on every session for every affected patient.
- We verify carve-out payer status before the first session is delivered.
- We track session-level authorization balances daily across all payers.
- We audit time-based code documentation before every claim submission.
- We identify and bill Interactive Complexity (90785) on every eligible session.
- We file mental health parity appeals when payers apply unlawful restrictions.
Common Behavioral Health Revenue Leaks
1Time-Based Coding Errors
Therapy codes are strictly time-based. Billing 90837 (60 min) for a 45-minute session triggers immediate audits and recoupment. We audit documentation to ensure that start and stop times in the clinical note match the code billed — protecting your practice from retroactive paybacks on thousands of claims.
2Carve-Out Payer Routing Errors
Mental health benefits are often 'carved out' to a separate managed behavioral health organization (MBHO). United Healthcare patients may use Optum for mental health. Aetna patients may use Aetna Behavioral Health. Sending claims to the medical payer instead of the MBHO means automatic denial. We verify carve-out status before the first session.
3Prior Authorization Expiration
Unlike medical visits, ongoing therapy typically requires re-authorization every 8–20 sessions. Most practices don't track these exhaustion dates until a claim denies — by which point multiple sessions are at risk. We alert your team 2 weeks before every authorization expires, so care is never interrupted and revenue is never at risk.
4Missed Add-On Code Revenue
Many clinicians miss billing for Interactive Complexity (90785) when treating children with language barriers, high-conflict family situations, or when using an interpreter. This add-on code pays an extra $17–$28 per session and requires only a one-sentence documentation note — yet fewer than 20% of eligible sessions include it.
Three Revenue Streams Most Behavioral Health Practices Never Bill
These opportunities exist in virtually every behavioral health practice. They require no new patients — just the right billing structure applied to work your clinicians are already doing.
Collaborative Care Model (CoCM)
CPT 99492 / 99493 / 99494
The Collaborative Care Model allows a consulting psychiatrist to bill for population-level care management without seeing patients directly. Working with a panel of 60 primary care patients, a consulting psychiatrist can earn $1,800–$3,200 per patient per year for 30–60 minutes of monthly registry review and care team consultation. Most behavioral health groups don't know this code exists.
Group Therapy Billing
CPT 90853 / 90849
Group therapy (90853) allows you to bill separately for every patient in the group — typically 6–10 patients per session. A single 90-minute group session with 8 patients generates $360–$600 in billing at a fraction of the time of 8 individual sessions. We structure your group billing workflow to ensure each patient's claim includes the correct group code and authorization.
Telehealth Parity Revenue
POS 02 / 10 · Modifiers 95, GT
Most states now have telehealth parity laws requiring commercial payers to reimburse mental health telehealth at the same rate as in-office visits. The distinction between Place of Service 02 (patient not in their home) and POS 10 (patient at home) has a significant reimbursement impact under Medicare. We ensure you capture the correct rate for every telehealth session delivered.
Common Behavioral Health CPT Codes We Bill
These are the high-volume codes where behavioral health billing errors — and revenue losses — most commonly occur.
| CPT Code | Procedure Description | Common Billing Issue |
|---|---|---|
| 90791 | Psychiatric diagnostic evaluation (initial assessment) | Billed when ongoing therapy is provided — 90791 is only for initial evaluation |
| 90837 | Individual psychotherapy, 60 minutes | Time documentation missing start/stop times; 45-min sessions billed as 60-min |
| 90834 | Individual psychotherapy, 45 minutes | Used interchangeably with 90837 — time must match exactly or claim denies |
| 90847 | Family psychotherapy with patient present | Billed without patient in session (should be 90846); authorization not covering family therapy |
| 90785 | Interactive complexity add-on to psychotherapy | Frequently missed; requires only brief documentation note to support |
| 90853 | Group psychotherapy (per patient) | Billed once for the whole group instead of per-patient; authorization missing group type |
| 99492 | CoCM initial month (70 min, consulting psychiatrist) | Almost universally unbilled; most behavioral health groups not enrolled in CoCM |
| H0015 | Alcohol/drug treatment program, per hour (HCPCS) | Billed without ASAM level-of-care documentation supporting the intensity level |
Full-Spectrum Behavioral Health RCM
Whether you are a solo private practice, a group therapy center, or a large SUD treatment facility, we have the specialized workflows to manage every aspect of your revenue cycle.
Outpatient Therapy & Psychiatry
We manage the full spectrum of outpatient behavioral health codes — diagnostic evaluations (90791/90792), E/M visits for medication management (99213–99215), individual therapy (90832–90837), and psychotherapy add-ons (90833/90836). We validate diagnosis pointers and authorization status before every claim submission.
Telehealth Parity Management
Telehealth billing rules vary by state and payer. We track parity laws for every state you practice in, apply the correct modifiers (95, GT, FQ) and Place of Service codes (02 vs. 10), and ensure you receive the in-office reimbursement rate wherever parity law mandates it.
Substance Use Disorder (SUD) Billing
For IOP and PHP facilities, we manage complex daily and per-diem billing structures (H0015, H0035). We track concurrent authorization units, verify ASAM level-of-care documentation aligns with the level billed, and prevent the costly denials that result from documentation mismatches.
Psychological Testing
Testing (96130–96136) is a high-value revenue stream but requires meticulous time documentation. We separate administration time (technician or computer-administered) from professional interpretation time, ensuring both are billed at the appropriate rate and that payer pre-authorization is in place.
Group Practice & Incident-To Billing
In group practices, billing Master's-level clinicians (LCSW, LPC, LMFT) under a psychiatrist's NPI requires strict supervision adherence. We structure your incident-to billing workflows for compliance — so you capture the higher reimbursement rates without exposure to False Claims Act liability.
Credentialing & Payer Enrollment
Behavioral health panels are frequently closed or hard to join. Our credentialing team specializes in CAQH profile management and panel applications for LCSWs, LMFTs, psychologists, and psychiatrists — getting you in-network faster and opening access to the payer reimbursement rates your practice deserves.

Behavioral Health Billing FAQs
Answers to the billing questions therapists, psychiatrists, and practice managers ask us most.
QWhy is behavioral health billing different from regular medical billing?
Behavioral health billing involves unique challenges that generalist billers are rarely trained for: carve-out payers where mental health benefits are managed by a completely separate insurance entity, time-based coding where exact session minutes determine the CPT code, ongoing authorization requirements that expire mid-treatment, and strict HIPAA-42 CFR Part 2 privacy rules for substance use records. A medical biller who doesn't know that UHC mental health claims go to Optum — not UHC — will generate a 100% denial rate on those claims.
QWhat is a carve-out and how does it affect billing?
A carve-out means that a patient's mental health benefits are managed by a separate behavioral health organization (MBHO) rather than their main medical insurer. For example, a United Healthcare member may have their mental health claims processed by Optum Behavioral Health, while their medical claims go to UHC. Sending the claim to the wrong entity causes an automatic denial. We verify carve-out status at eligibility verification — before the first session is ever delivered.
QHow do you manage prior authorizations for ongoing therapy?
We maintain an active authorization tracker for every patient in your panel. The system logs the approval date, the number of authorized sessions, sessions used, and the expected exhaustion date. We alert your front desk 2 weeks before an authorization runs out, so you can submit for re-authorization without interrupting care or generating unbillable sessions. Most practices only discover an authorization lapsed when a claim denies — by which time 5–10 sessions may be at risk.
QCan I bill for phone calls or texts with patients?
It depends on the payer and the nature of the contact. There are specific codes for telephone assessment and management: 99441–99443 for physicians and psychiatrists, and 98966–98968 for non-physician providers. These require at least 5 minutes of assessment work (not administrative) and cannot be used when a face-to-face visit is scheduled within 24 hours. We evaluate your payer contracts to identify which payers cover telephone services and build a workflow so eligible calls are captured.
QWhat is the Collaborative Care Model and can we bill for it?
The Collaborative Care Model (CoCM) allows a psychiatric consultant to bill for population-level care management using a patient registry — without seeing patients directly. The primary care practice bills the care manager time and receives shared revenue. For psychiatrists and psychiatric APRNs, CPT codes 99492, 99493, and 99494 cover monthly registry-based consultation, paying $180–$275 per enrolled patient per month. Most behavioral health practices are eligible but have never been enrolled. We handle the full enrollment and billing setup.
QHow do you handle group therapy billing?
Group therapy (CPT 90853) is billed separately for every patient in the group — not once for the entire session. A group of 8 patients generates 8 individual claims. We structure your group scheduling and billing workflow to ensure each patient's claim includes the correct code, the right authorization (group therapy requires its own authorization from most payers), and the appropriate diagnosis codes. We also track which payers require the therapist to be credentialed as a group therapist vs. individual.
QWhat EHR and practice management systems do you work in?
We work natively in the major behavioral health platforms: SimplePractice, TherapyNotes, Valant, Osmind (for ketamine/TMS practices), and ICANotes for psychiatric facilities. We also work in broader medical EHRs including Epic, athenahealth, eClinicalWorks, and Kareo when behavioral health practices use them. You should never have to teach your billing team how to use your software — we train in your system before going live.
QHow does mental health parity law affect our billing and collections?
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires commercial insurers to cover mental health and SUD services at benefit levels no more restrictive than medical/surgical benefits. In practice, this means if a payer covers 60 physical therapy visits per year, they cannot limit mental health therapy to 20 visits. We actively monitor parity violations in your denials — and when a payer is applying more restrictive limits to mental health than medical, we file parity complaints and appeals that frequently overturn systematic denials.
