Which CPT codes come up most in mental health billing?
Time thresholds and documentation drive both reimbursement and denials. These are the codes we handle every day:
| CPT code | What it covers | The detail that prevents denials |
|---|---|---|
| 90791 | Psychiatric diagnostic evaluation (no medical services) | Most payers pay it once per provider per episode. Repeat 90791s need clear justification. |
| 90792 | Psychiatric diagnostic evaluation with medical services | Physician/prescriber evaluation. Don’t downcode to 90791 when medical services occurred. |
| 90834 | Psychotherapy, 45 minutes (38–52 min) | The safe default. But under-coding real 53+ minute sessions here leaves money on the table. |
| 90837 | Psychotherapy, 60 minutes (53+ min) | Payers audit it: documented start/stop times and clinical justification make it stick. |
| 90833 / 90836 / 90838 | Psychotherapy add-on with E/M (psychiatry) | Must be billed with an E/M code by a prescriber. Time is counted separately from the E/M work. |
| 90846 / 90847 | Family therapy (without / with patient present) | Coverage varies sharply by payer; some require the identified patient’s diagnosis to drive medical necessity. |
| 96130–96139 | Psychological & neuropsych testing | Unit-based codes; authorization for the full battery up front avoids partial denials. |
| 97151–97158 | ABA / adaptive behavior services | Authorization unit tracking is everything. Going over authorized units is unpaid work. |
How does telehealth change mental health billing?
Telehealth is now core to behavioral health, and a top denial source. Claims must carry the right combination of modifier 95 (or GT for payers that still require it) and place-of-service code: POS 02 (telehealth, patient not at home) or POS 10 (telehealth, patient at home). Payers differ on which combination they accept, and several pay different rates by POS. We maintain a per-payer telehealth matrix for every practice we bill, so the same session never bounces twice.
Already sitting on behavioral health denials?
That’s our favorite starting point. The free audit quantifies what’s recoverable in your last 90 days, and recovery runs on contingency. No recovery, no fee.
How contingency denial recovery works →Behavioral health billing questions
Why do behavioral health claims get denied so often?
The most common causes are time-based coding errors (90837 billed without documented session time), missing or expired prior authorizations, telehealth claims with the wrong modifier or place-of-service code, credentialing gaps where the rendering provider isn’t properly enrolled, and payer-specific medical-necessity rules for longer or more frequent sessions.
Do you bill for associate-level and pre-licensed clinicians?
Yes, where payer rules allow it. Billing under supervision is payer- and state-specific: some payers credential associate licenses directly, others require billing under a supervisor with specific modifiers. Getting this wrong causes recoupments, so we map the rules per payer before the first claim.
Can you handle both insurance billing and superbills for private-pay clients?
Yes. Many practices run hybrid models. We handle in-network claims end to end and generate accurate superbills for out-of-network clients so their reimbursement doesn’t become your admin problem.
Do you work with my EHR?
We work inside the systems behavioral health practices actually use: SimplePractice, TherapyNotes, Tebra/Kareo, Sessions Health, and others. No platform switch required.
What does behavioral health billing cost with Noblex?
A percentage of monthly collections for full billing (see the pricing page for ranges and what determines your rate), and contingency-only for denial and old A/R recovery: no recovery, no fee. Month-to-month, no long-term contract.
