Mental Health Billing Services

Behavioral health practices lose more revenue to administrative rules than to clinical complexity. Session-limit authorizations, payer-specific telehealth policies, and time-based psychotherapy codes create denials that repeat every single week until someone fixes the root cause. ERG bills mental health full-time — therapy, psychiatry, group and intensive outpatient — for practices across the United States.

What makes it hard

Mental Health & Behavioral Health billing challenges we solve

These are the issues that repeat every month in mental health & behavioral health practices — and the ones we fix at the source rather than reworking claim by claim.

Authorization and session limits

Many behavioral health plans authorize a fixed number of visits. When the count lapses mid-treatment, every subsequent claim denies — and the patient keeps being seen. We track auth counts and re-authorize before they run out, not after.

Time-based psychotherapy coding

30, 45 and 60-minute psychotherapy codes are chosen by documented time. Mismatches between documented time and the billed code are a top audit and denial trigger.

Telehealth policy that varies by payer

Place-of-service and modifier requirements for virtual sessions differ between Medicare, Medicaid and commercial plans, and they change. One wrong POS can deny an entire month of sessions.

Credentialing and closed panels

Behavioral health panels close more often than other specialties, and out-of-network claims price very differently. Enrollment gaps quietly become unpaid claims.

Split E/M and psychotherapy billing

Psychiatry visits that combine medication management with therapy require the evaluation and management service plus the correct psychotherapy add-on. Getting this pairing wrong underpays the visit.

Coding depth

Common code families we work with

  • 90791 / 90792 — psychiatric diagnostic evaluation, with and without medical services
  • 90832 / 90834 / 90837 — psychotherapy, 30 / 45 / 60 minutes
  • 90833 / 90836 / 90838 — psychotherapy add-ons billed with an E/M service
  • 90846 / 90847 — family psychotherapy, without and with the patient present
  • 90853 — group psychotherapy
  • 99202–99215 — office E/M for medication management
  • 96127 — brief emotional/behavioral assessment

Listed for context only — this is not billing advice, and payer policy varies. Our certified coders work to AAPC and AHIMA standards.

Denial prevention

Top denial drivers in mental health & behavioral health

  • Expired or exhausted prior authorization
  • Documented time not supporting the psychotherapy code billed
  • Incorrect telehealth place of service or modifier
  • Provider not credentialed with the plan on the date of service
  • Missing or non-specific diagnosis coding

We root-cause denials by payer and procedure, then fix the upstream workflow so the same denial stops recurring.

FAQ

Mental Health & Behavioral Health billing — common questions

Do you bill for therapists as well as psychiatrists?

Yes. We bill for LPCs, LCSWs, LMFTs, psychologists, psychiatric nurse practitioners and psychiatrists — including practices that mix therapy with medication management, and group practices with multiple rendering providers under one tax ID.

Can you handle telehealth mental health claims?

Yes. Virtual behavioral health is a large share of the claims we process. We track each payer's place-of-service and modifier requirements so telehealth sessions are paid at the correct rate rather than denied or downcoded.

Do you manage prior authorizations for behavioral health?

Yes. We track authorized visit counts per patient per payer and initiate re-authorization before the units run out, which is the single most common cause of avoidable denials in this specialty.

What does mental health billing cost?

Our billing is a percentage of what we actually collect for you, tailored to your specialty, volume and payer mix. There is no long-term contract. We will quote your practice after an A/R analysis.
