Psychiatry BillingComplete Coding & Revenue Guide (2026)Top CPT codes with current RVU data, denial patterns, modifier rules, bundling pitfalls, and revenue opportunities for psychiatry practices.
Top CPT Codes
The highest-value psychiatry CPT codes with current RVU data and Medicare payment from the CY 2026 Physician Fee Schedule. Click any code for the full payment, bundling, and modifier guide.
Most practices under-capture revenue on these codes through downcoding, missed modifier 25, stale fee schedules, or misapplied bundling. Our coders audit every line against the documentation before submission so the revenue earned actually gets billed.
Bundling Pitfalls
5 trapsThe code pairs that trigger NCCI edits and CO-97 denials in psychiatry. Know these before billing.
90834: 90837: Individual therapy codes are mutually exclusive per date. 90832 (16-37 min), 90834 (38-52 min), 90837 (53+ min). Bill the one matching ACTUAL face-to-face time.
90833: 99214: 90833/90836 are ADD-ON codes to E/M. Must bill with 99213/99214/99215 as the base code. Cannot bill 90833 alone.
90834: 99214: E/M + individual therapy on same day by same provider: Use add-on codes (90833/90836) with E/M, NOT standalone therapy codes (90832/90834/90837) + E/M.
96127: 96130: Brief emotional screening (96127) bundles with full neuropsych testing (96130-96139). If doing full testing, do not also bill the screening.
90846: 90847: Family therapy without patient (90846) vs with patient (90847) — cannot bill both on same date.
CO-97 bundling denials are recoverable with correct modifier documentation. Most billers write them off. We work each one against the clinical record and resubmit with the right modifier 25 or 59 path.
Modifier Guidance
When to apply each modifier in psychiatry claims. Wrong modifier application is the top single-line denial trigger and a leading audit target.
Rarely needed in psychiatry since therapy add-on codes (90833/90836) replace the need for modifier 25. Only use when billing E/M + a non-therapy procedure (e.g., 96127 screening) same day.
Reduced services — use when a therapy session is cut short (e.g., patient leaves early from 90837 after 40 min = 90834, not 90837-52).
Telemedicine — psychiatry has broad telehealth coverage post-COVID. Most payers cover 90834/90837 via telehealth. Use POS 02 (telehealth) or 10 (patient home).
Group therapy (90853) — some Medicaid plans require HQ modifier for group settings.
Separate encounter — use when performing diagnostic eval (90791) and therapy (90834) on same day as distinct sessions.
Revenue Opportunities
6 playsThe billing codes and services most psychiatry practices under-capture. Each one is a recurring revenue lift, not a one-time fix.
Therapy add-on codes: By combining E/M + therapy add-on (99214 + 90836), reimbursement is $180-280/visit vs $110-150 for standalone therapy (90834). This is the single biggest revenue optimization in psychiatry.
Collaborative Care Model (CoCM): 99492 pays $160-180/month per patient. A psychiatrist consulting on 200 primary care patients generates $32,000-36,000/month. Requires care manager + measurement-based care.
Psychological testing: 96130 (first hour) + 96131 (additional hours) pays $150-200/hour for ADHD, autism, dementia evaluations. Often referred out — bringing in-house captures this revenue.
PHQ-9/GAD-7 screening (96127): $5-8 per screening, unlimited frequency. With 20 patients/day = $100-160/day in screening revenue alone. Takes 2 minutes to administer.
Telehealth efficiency: Psychiatry telehealth reduces no-show rates by 35-40%. More completed sessions = more billable visits. No overhead for office space on telehealth days.
MAT for opioid use disorder: Buprenorphine prescribing (XDEA waiver no longer required) generates E/M visits + monthly management. Each OUD patient = $2,000-3,000/year in E/M revenue plus improved outcomes.
Documentation Checklist
What the chart must contain to support billing. Missing documentation means audit vulnerability.
- Individual therapy (90832/90834/90837): Document session start and stop time (face-to-face with patient, not total encounter time). Document therapeutic modality used (CBT, DBT, psychodynamic, supportive). Summarize key themes, patient response, and treatment plan updates.
- Psychiatric diagnostic evaluation (90791/90792): Comprehensive documentation — chief complaint, HPI, psychiatric history, substance use history, family psychiatric history, social history, mental status exam, risk assessment (SI/HI/AVH), DSM-5 diagnoses, treatment plan. 90792 includes medical exam component.
- E/M + therapy add-on (99214 + 90833): Document the E/M portion separately — medication review, side effects, lab review, treatment response. Then document the therapy portion — duration, modality, content. Both must be clearly delineated.
- Medication management: Many payers do not have a standalone 'med management' code. Bill E/M (99213/99214) for medication visits. Document medication names, doses, side effects, compliance, and clinical decision-making.
- Risk assessment: Document suicide risk assessment at EVERY visit — ideation, plan, intent, means, protective factors. Use validated tools (PHQ-9, C-SSRS). Required by Joint Commission and most payers.
Coding Workflow
Step by step approach for coding psychiatry encounters correctly.
1. Determine visit type: diagnostic eval (90791/90792) vs therapy vs medication management vs combination. 2. For therapy: time the face-to-face session — 16-37 min = 90832, 38-52 min = 90834, 53+ min = 90837. 3. If combining E/M + therapy same visit: bill E/M (99213-99215) + add-on therapy code (90833 for 16-37 min, 90836 for 38-52 min). 4. For group therapy: 90853 per patient. 5. For family therapy: 90846 (without patient) or 90847 (with patient). 6. Screen for depression (PHQ-9) and anxiety (GAD-7): bill 96127 per instrument. 7. For testing: 96130 (first hour, psychologist) + 96131 (each additional hour). Technician-administered: 96136 + 96137. 8. Collaborative care (CoCM): 99492 (first 70 min/month), 99493 (subsequent 60 min), 99494 (each additional 30 min).
