Psychiatry billing services from Medical Billing Services Group (MBSG) handle the medication-management-centered visit mix: E/M with psychotherapy add-ons, psychiatric diagnostic evaluations, interactive complexity, and time-based coding — with denial recovery across Medicare, Medicaid, and commercial behavioral health carve-outs.

Practice and setting fit
Psychiatry billing differs from general behavioral health billing in its center of gravity: the psychiatrist’s day is built on evaluation and management — diagnostic evaluations, medication management follow-ups, and medical decision-making — with psychotherapy reported as timed add-ons to the E/M rather than standalone session codes. That structure creates its own failure modes: add-on codes billed without a payable primary E/M, time thresholds not met or not documented, and interactive complexity reported without the required communication factors in the note.
MBSG supports all specialties we serve from one revenue cycle team, and our behavioral health billing services cover the therapy-centered side (standalone psychotherapy sessions, group and family work). This page is the psychiatry side: E/M-driven, medication-management-heavy, and audited against a different rule set. Remote delivery covers your practice in all 50 states from one billing operation.
Documentation and coding risks
Psychiatry claims fail on time documentation and add-on pairing rules. The examples below come from public CMS sources — described in our own words, reviewed against the source text on 2026-10-08.
Psychotherapy add-ons require a payable E/M (CMS/NCCI)
The psychotherapy add-on codes 90833 (30 minutes), 90836 (45 minutes), and 90838 (60 minutes) are reported only with a primary E/M service — they describe psychotherapy performed on the same day as evaluation and management by the same clinician. Two consequences follow: the E/M itself must be separately payable (medical necessity, documented decision-making), and the psychotherapy time must be face-to-face, documented in minutes, and distinct from the E/M work. National Correct Coding Initiative procedure-to-procedure edits govern which combinations payers will accept together. Billing the add-on without a qualifying primary E/M, or without distinct time documentation, is the most common psychiatry bundling denial.

Interactive complexity has required elements (CPT/CMS)
Add-on code 90785 (interactive complexity) is reported with psychiatric services when specific communication factors complicate the delivery of care — for example, the need to manage maladaptive communication, caregiver emotions interfering with treatment, or mandated reporting discussions. It is never reported alone and never with psychotherapy codes when the psychotherapy is the primary service in certain payer configurations. The chart must describe the complicating factor; a bare 90785 on the claim without supporting documentation is routinely denied.

Diagnostic evaluations: 90791 vs. 90792 (CMS)
Code 90791 covers the psychiatric diagnostic evaluation without medical services; 90792 covers the evaluation with medical services (the psychiatrist’s medical assessment, including history, examination, and medical decision-making). New-patient evaluations billed under the wrong code — medical work performed but 90791 reported, or no medical component with 90792 — create both revenue loss and audit risk. Payers also apply their own frequency limits on diagnostic evaluations; verify before re-evaluating an established patient.

Payer and authorization checks
Psychiatry sits at the intersection of medical benefits and behavioral health carve-outs: the same practice may bill E/M through the medical benefit and therapy services through a managed behavioral health organization, each with its own credentialing, authorization, and timely-filing rules. Telehealth adds another layer — place-of-service and modifier requirements changed repeatedly in recent years and still vary by payer. Verify each payer’s current telehealth, authorization, and carve-out rules before projecting revenue; Medicare rules do not automatically extend to commercial or Medicaid plans. Our denial management workflow separates authorization denials from coding denials so each gets the right fix.
Workflow and reporting
A psychiatry workflow checks every add-on against its primary E/M before submission — payable primary, distinct documented minutes, correct time threshold — verifies interactive complexity has a charted complicating factor, confirms diagnostic evaluations use the medical-services variant only when medical work was performed, and keeps diagnosis coding current with the FY 2027 ICD-10-CM update (effective October 1, 2026 through September 30, 2027). Carve-out claims are tracked separately from medical-benefit claims because their denial patterns differ. Monthly reporting is built from your actual data; illustrative examples: add-on capture rate per E/M visit, denial rate by reason code and by payer type (medical vs. carve-out), AR over 90 days, telehealth vs. in-person claim mix. Plain-English background on denials and coding basics is in our billing resources.
Onboarding and pricing factors
We do not publish flat rates — psychiatry billing cost depends on encounter volume and visit mix, not just provider count. Honest quote factors: monthly encounter volume, providers and locations, payer and carve-out mix, telehealth share, your EHR and practice-management system, whether coding is included, and existing AR backlog. Pricing model, minimum fees, turnaround times, and staff credentials are scoped in your written proposal — contact us for terms tailored to your practice. We work inside your existing systems; compatibility is confirmed during onboarding. Data is handled under our HIPAA safeguards and business associate agreement. States served: all 50 states. See our pricing page, or contact us at +1 (307) 396-4107 or contact@medicalbillingservicesgroup.com for a scoped quote.
FAQs
Can we bill psychotherapy and E/M on the same day?
Yes — with the add-on codes 90833, 90836, or 90838 reported alongside a payable E/M service. The psychotherapy time must be face-to-face, documented in minutes, meet the code’s time threshold, and be distinct from the E/M work.
When is interactive complexity (90785) appropriate?
When specific communication factors complicate care — such as managing maladaptive communication, interfering caregiver dynamics, or mandated reporting discussions — and the factor is documented in the note. It is an add-on only, never standalone.
What is the difference between 90791 and 90792?
90791 is the psychiatric diagnostic evaluation without medical services; 90792 includes the medical component (history, examination, medical decision-making). Use 90792 only when the psychiatrist performs medical assessment work.
How do behavioral health carve-outs affect billing?
The same practice may bill medical-benefit E/M and carve-out therapy services under different contracts, each with its own credentialing, authorization, and filing rules. Track them separately — their denial patterns differ.
