Specialty billing

Mental health billing for therapy and psychiatry groups

This page is for group practices that bill therapy and psychiatry together. Solo therapy practices, testing-heavy psychology practices, and LPC or LCSW-only practices each have their own page, linked below.

Use a more specific page when it matches

Behavioral health still shares the same denial patterns: time-based codes, authorizations, and telehealth place of service. The group page covers that shared revenue cycle. Switch pages when the practice is solo, testing-focused, or limited to counselor and social-work licenses.

Why behavioral health claims get denied

  • Time-based codes (90832, 90834, 90837) that don't match documented session time
  • Authorizations that run out of visits or expire without anyone noticing
  • Telehealth claims with the wrong place of service (02 vs 10) or missing modifier 95
  • Add-on codes like 90785 (interactive complexity) or 90840 (crisis) billed without support
  • Eligibility changes, especially Medicaid managed care and plan-year changes
  • Clinicians not linked correctly to the group contract after credentialing

What we do differently

We check claims against behavioral-health-specific rules before submission, track authorizations automatically, and give you a dashboard that shows collections and denials by clinician, payer and CPT code. You keep your own payer contracts and negotiated rates. We just make sure you're paid on them.

Codes we bill every day

Psychiatric diagnostic evaluations (90791, 90792), individual psychotherapy (90832, 90834, 90837), psychotherapy add-ons with E/M (90833, 90836, 90838), family therapy (90846, 90847), group therapy (90853), crisis psychotherapy (90839, 90840), interactive complexity (90785), and psychiatric E/M visits (99202–99215).

Keep your contracts, or join a network?

Networks like Headway and Alma can simplify insurance for solo clinicians, but the payer relationship and rates are theirs. If you run a group practice or plan to grow, holding your own contracts gives you control of rates, data and referrals. We provide the billing and credentialing support that makes that practical.

Frequently asked questions

Do you work with solo therapists?+

Yes, though our packages are designed for group practices with 3–15 clinicians. Solo clinicians often start with credentialing and our Essentials billing plan.

Which EHRs do you support for mental health billing?+

SimplePractice, TherapyNotes, Valant, TheraNest, Tebra and most other behavioral health EHRs. We work inside your system.

Can you bill Medicare for LPCs and marriage and family therapists?+

Yes. Since 2024, Medicare covers services from marriage and family therapists and mental health counselors. We handle their enrollment and billing.

How do you handle 42 CFR Part 2 records?+

Substance use disorder treatment records have additional confidentiality rules. Our access controls and workflows are designed for them, and we sign a BAA (and Part 2 agreements where required).
