Mental Health & Psychiatry Billing — Get Paid for Every Session You Deliver

Mental health billing is the most documentation-sensitive specialty in all of medicine. One wrong code, one mismatched place of service, one missing modifier — and the claim denies. Netix knows the exact rules your payers follow, so your sessions get paid the first time.

THE PROBLEM

Why Mental Health Practices Lose More Revenue Than Any Other Specialty

Mental health providers deliver life-changing care — and then spend hours fighting to get paid for it. The billing challenges in behavioral health are unlike any other specialty

Documentation depth requirement is extreme

Payers audit mental health claims more aggressively than almost any other specialty. A 45-minute therapy session billed as CPT 90837 requires specific documentation that proves medical necessity — not just a progress note. Missing elements mean denied claims, recoupment demands, and audits.

Code selection errors are constant

The difference between CPT 90832 (30 min), 90834 (45 min), and 90837 (60 min) comes down to documented time — and most practices underbill because they’re unsure of the threshold. That’s revenue left on the table every single session.

Telehealth created a new layer of complexity.

Post-pandemic telehealth coverage varies dramatically by payer, by state, and by CPT code. The wrong modifier (or a missing one) on a telehealth session turns a paid claim into an instant denial.

Behavioral health payer panels are restrictive.

Getting credentialed with behavioral health payers — especially for out-of-network conversion and Medicaid behavioral health managed care organizations — requires specialty-specific knowledge most general credentialing services don’t have.

Place of service mistakes are the #1 denial cause.

POS 02 (telehealth), POS 10 (telehealth in home), POS 11 (office), POS 12 (home) — one wrong digit on the claim form means automatic denial. It’s the most common and most preventable error in mental health billing.

Getting enrolled with the right behavioral health payer panels is an important step before a practice can consistently submit and receive payment for covered services. Our payer enrollment support helps practices manage the credentialing and enrollment process with the appropriate insurance networks.

OUR MENTAL HEALTH BILLING SERVICES

What Netix Handles for Mental Health & Psychiatry Practices

Psychotherapy Session Billing

Accurate CPT code selection across the full range of individual, family, and group psychotherapy codes — timed correctly, documented properly, submitted clean.
Individual therapy: 90832 · 90834 · 90837
Crisis psychotherapy: 90839 · 90840
Family therapy: 90846 · 90847
Group therapy: 90853

Psychiatric Evaluation & E&M Billing

Psychiatric diagnostic evaluations (90791, 90792) and the correct application of E&M codes when medication management is combined with psychotherapy — the combination coding rules that trip up most psychiatric practices.

Telehealth Billing & Modifier Compliance

Correct modifier application (95, GT, 93) by payer, place of service coding for telehealth (POS 02 vs POS 10), and payer-specific telehealth coverage verification before the session — not after the denial.

Behavioral Health Credentialing

Enrollment with commercial behavioral health payers, Medicaid behavioral health managed care organizations, Medicare, and EAP panels — with weekly follow-up until every provider is approved and actively billing.

Prior Authorization Management

Auth requirements for intensive outpatient (IOP), partial hospitalization (PHP), psychological testing, and TMS — identified upfront and secured before treatment begins.

Denial Management — Behavioral Health Specific

Every denied mental health claim categorized by root cause — place of service, medical necessity, authorization, credentialing — and appealed with the specific clinical documentation payers require.

Accounts Receivable Recovery

Mental health AR ages fast when sessions are billed daily and denials pile up. We work every open claim before timely filing deadlines expire — especially critical for high-volume therapy practices.

Denied claims can have a significant impact on behavioral health practices, especially when issues involve documentation, coding, eligibility, or payer requirements. Our denial follow-up process helps identify the reasons behind rejected claims, address the underlying issues, and work toward recovering eligible revenue.

TELEHEALTH BILLING

Mental Health Telehealth Billing — Getting It Right Every Time

Telehealth transformed mental health — and created a billing minefield. Here is what changes on every telehealth claim

Place of Service

POS 02 for provider location, POS 10 when patient is at home — and payers handle this differently. Wrong POS = instant denial.

Modifiers

Modifier 95 (synchronous telehealth), GT (Medicare telehealth), 93 (audio-only) — applied by payer, not uniformly across all claims.

Payer coverage rules

Some commercial payers still limit telehealth CPT codes, require pre-authorization for audio-only, or have state-specific coverage rules that override national policy.

We verify telehealth coverage per payer per patient before the session

so your therapists see patients confidently and your claims get paid cleanly.

FAQ

Mental Health Billing Questions

What is the most common denial in mental health billing?

Place-of-service mismatch — especially since telehealth expanded. POS 02 vs POS 10 vs POS 11 errors account for a significant share of mental health denials. We catch these before submission.

Can you bill for telehealth sessions across all payers?

Yes — with payer-specific modifier and POS rules applied to every claim. Telehealth coverage varies by payer and state; we verify coverage before the session, not after the denial.

Do you handle credentialing with behavioral health payer panels?

Yes — including commercial behavioral health panels (which operate separately from medical panels), Medicaid behavioral health managed care organizations, Medicare, and EAP networks.

We have a backlog of unpaid therapy sessions. Can you recover them?

Yes — old AR recovery is one of the first things we tackle. Mental health has strict timely-filing limits (most payers: 90–180 days from date of service). We prioritize by deadline, not by ease.

Can you handle billing for multiple therapists in a group practice?

Yes — multi-provider group practices are a core part of what we do. Each provider gets their own credentialing, their own claim tracking, and their own performance reporting in the monthly dashboard.

What makes mental health billing different from general medical billing?

Documentation sensitivity, telehealth complexity, behavioral health payer panel restrictions, and the combination coding rules when psychiatry and therapy overlap. A general biller learns this on your revenue — we arrive knowing it.
