Psychiatry Billing — Built for Your Practice
Psychiatry billing sits at the intersection of time-based medicine, insurance discrimination, and constantly shifting telehealth regulations. The mental health parity law says insurers must cover psychiatric care the same as physical medicine — but most don't, and most practices never challenge it.
Our psychiatry billing team does three things most billing companies won't: we correctly apply the E&M-plus-psychotherapy add-on structure so you're never leaving money on the table in combined visits, we enforce mental health parity rights with formal appeals that recover denied claims, and we stay current on behavioral health telehealth rules that have changed repeatedly since 2020.
Why Psychiatry Billing Is Complex
Where psychiatry billing trips up even experienced coders:
- E&M vs. therapy code selection — medication management only = E&M; therapy only = 90832-90838; both in same visit = E&M + add-on code (90833/90836/90838). Billing two standalone codes on the same date = automatic denial
- Time documentation — therapy codes are time-based and require documented start/stop time or total face-to-face minutes. Insufficient documentation triggers post-payment audits
- Mental health parity — payers illegally apply stricter prior auth, session limits, and cost-sharing to mental health. Most practices accept it; we challenge it
- Telehealth rules — behavioral health telehealth has favorable carve-outs under Medicare and many commercial payers that general telehealth billing misses entirely
- PHP/IOP per-diem billing — partial hospitalization and intensive outpatient require specific documentation for hours, services, and treatment plan currency

Top Psychiatry Claim Denial Reasons — and How We Eliminate Them
Most Psychiatry denials are preventable. Our team knows exactly what to look for before submission.
❌ Dual Standalone Code Denial (E&M + Therapy Same Date)
Billing 99213 AND 90837 as two standalone codes on the same date of service is invalid. The correct approach is E&M + the add-on psychotherapy code (90833/90836/90838). This is the single most common psychiatry billing error.
✓ Our Fix
Our psychiatry coders identify every combined E&M + therapy visit and automatically bill the correct add-on structure. We also audit past claims for this pattern and file corrected claims for any underpayments.
❌ Mental Health Parity Prior Auth Denial
Payers impose prior authorization for mental health visits more frequently than for comparable medical services — a direct violation of the MHPAEA. Most practices write off these denials.
✓ Our Fix
We document parity violations by comparing the payer's medical management criteria for mental health vs. medical/surgical services. We file formal MHPAEA parity complaints that typically result in retroactive payment for denied sessions.
❌ Telehealth Behavioral Health Coding at Wrong Rate
Behavioral health telehealth services bill under different rules than general medical telehealth under Medicare and many commercial payers. Billing at general telehealth rates instead of behavioral health-specific rates results in systematic underpayment.
✓ Our Fix
We apply the correct POS codes (02, 10), modifiers (95, GT), and behavioral health telehealth billing pathways for every remote psychiatric service — including audio-only mental health visits where permitted.
❌ Time Documentation Audit Trigger
CMS and commercial payers audit time-based therapy code claims for documentation of start time, end time, and total face-to-face minutes. Vague documentation ("1-hour session") without specific times creates audit risk.
✓ Our Fix
Before any psychotherapy claim is submitted, our review queue flags documentation that lacks required time elements and routes it back to the provider with specific remediation guidance.

If your psychiatrist performs medication management only, bill E&M codes (99202–99215) based on complexity. If performing psychotherapy only, bill the appropriate therapy code (90832 for 16–37 min, 90834 for 38–52 min, 90837 for 53+ min). When both occur in the same visit, bill the E&M code and add the appropriate psychotherapy add-on: 90833 (30 min therapy added to E&M), 90836 (45 min therapy added to E&M), or 90838 (60 min therapy added to E&M). Never bill two standalone codes for the same encounter.
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires payers to apply the same benefit limitations to mental health and substance use disorder services as they apply to medical/surgical services. Common violations include: more frequent prior authorization requirements for mental health, stricter medical necessity criteria, lower visit limits, and higher cost-sharing. When we identify these violations, we file state insurance department complaints and payer-level parity appeals. Successful challenges result in retroactive payment for denied sessions — sometimes recovering years of underpayments in a single proceeding.
LCSWs, LPCs, MFTs, and psychologists bill under their own NPIs for covered behavioral health services. Each has specific state-by-state insurance credentialing requirements. NPs and PAs in psychiatric practice may bill independently or incident-to the supervising psychiatrist depending on payer rules. We handle credentialing, enrollment, and billing for all mental health provider types.
Yes. PHP billing uses per-diem codes (H0035 for mental health PHP, H0015 for substance use) with documentation requirements for daily hours of service, services provided each day, and current treatment plan. IOP billing uses similar per-diem structure but at lower intensity thresholds. We handle both the professional billing for treating psychiatrists and the facility billing for the program itself.
Under the Consolidated Appropriations Act and subsequent extensions, Medicare expanded coverage for behavioral health telehealth services through 2024 and beyond, including audio-only services for established patients. Patients receiving mental health services via telehealth no longer need to travel to an originating site. Billing these services correctly — with the right POS code (02 for synchronous, 10 for audio-only) and the GT or 95 modifier — is essential to capture this revenue stream at full Medicare rates.
