CPT Code 90840: The Complete Guide to Crisis Psychotherapy Add-On Billing (2026)
If you've ever sat across from a patient in acute crisis — suicidal ideation, a psychotic break, acute trauma — you know that the next 30 minutes look nothing like a standard therapy session. Your clinical skills shift into high gear. So should your billing.
CPT code 90840 is the add-on code that lets you accurately capture the additional work of an extended crisis intervention. Yet it remains one of the most underused and most frequently audited codes in behavioral health billing. This guide breaks down exactly how to use it, document it, and defend it.
What Is CPT Code 90840?
CPT 90840 is an add-on code for crisis psychotherapy that covers each additional 30-minute block beyond the first 60 minutes of crisis intervention. It cannot be billed alone — it always pairs with the base crisis code, CPT 90839.
Here's the quick breakdown:
| Code | Description | Time Requirement | Standalone? | |------|-------------|-----------------|-------------| | 90839 | Psychotherapy for crisis; first 60 minutes | 30–74 minutes (base) | Yes | | 90840 | Psychotherapy for crisis; each additional 30 minutes | Each additional 30 min block | No — add-on only |
So if you provide 90 minutes of crisis psychotherapy, you bill 90839 + 90840 x1. If you provide 120 minutes, you bill 90839 + 90840 x2. Simple in theory. Complicated in practice.
Who Can Bill 90840?
Licensed mental health providers who can bill psychotherapy codes independently can bill 90840, including:
- Psychiatrists (MDs/DOs) — typically bill crisis codes as standalone or alongside E/M services
- Psychologists (PhDs/PsyDs)
- Licensed Clinical Social Workers (LCSWs)
- Licensed Professional Counselors (LPCs)
- Licensed Marriage and Family Therapists (LMFTs)
- Psychiatric Nurse Practitioners (PMHNPs) — with caveats depending on payer and state scope of practice
If you're billing incident-to under a supervising physician, payer rules vary significantly. Always verify before billing.
What Qualifies as a "Crisis" Under 90839/90840?
This is where most providers get into trouble. The AMA and most payers define a psychiatric crisis as a situation requiring urgent assessment and intervention due to:
- Active suicidal ideation with plan or intent
- Active homicidal ideation
- Acute psychosis or severe agitation
- Acute trauma response requiring immediate stabilization
- Severe self-harm requiring immediate clinical intervention
- Acute psychiatric decompensation that cannot wait for a scheduled appointment
This is not simply a patient who presents as more anxious or upset than usual. The distinction between a "difficult session" and a genuine psychiatric crisis is critical — both clinically and for billing purposes.
Key rule: If you could have conducted the session on schedule without any modification to your clinical approach, it probably doesn't meet crisis criteria. Ask yourself: "Was this patient's presentation an emergency requiring urgent stabilization?"
2026 Reimbursement Rates: What Are These Codes Actually Worth?
Reimbursement varies by payer, geography, and practice setting. Here are approximate Medicare 2025–2026 national non-facility rates as a benchmark:
| Code | Medicare Non-Facility | Medicare Facility | Average Commercial Rate | |------|-----------------------|------------------|------------------------| | 90839 | ~$213–$228 | ~$140–$155 | $250–$350 | | 90840 | ~$108–$118 | ~$72–$82 | $120–$175 per unit |
Medicaid rates vary dramatically by state — some states reimburse crisis codes at near-Medicare rates, while others pay as low as 60–70% of Medicare. Always verify your state's Medicaid fee schedule.
Commercial payers like Aetna, Cigna, UnitedHealthcare, and BlueCross generally reimburse at 120–160% of Medicare for crisis codes when properly documented. The catch? Their documentation requirements are equally demanding.
How to Document 90840 the Right Way
Documentation is where crisis billing either survives an audit or collapses under scrutiny. Here's what your note must capture:
1. Crisis Presentation
Document the specific precipitating event or symptom presentation that constitutes a crisis. Don't write "patient presented in distress." Write:
"Patient presented expressing active suicidal ideation with a specific plan to overdose on household medications, reporting intent within the next 24 hours. Patient endorsed hopelessness, anhedonia, and inability to identify reasons for living."
2. Risk Assessment
Document a formal, specific risk assessment:
- Suicidal/homicidal ideation (presence, plan, intent, means)
- Access to means
- Protective factors
- Previous attempts or hospitalizations
- Current substance use
3. Clinical Interventions Provided
Be specific about what you actually did during the crisis intervention:
- Safety planning
- Cognitive restructuring or de-escalation techniques
- Coordination with other providers or emergency services
- Contact with family members or supports (with consent)
- Decisions about level of care (outpatient vs. higher level)
4. Exact Time Documentation
This is non-negotiable. You must document:
- Start time
- End time
- Total face-to-face time
For 90840, the total time must reach at least 75 minutes (60+ minutes for 90839 plus 30 minutes to justify one unit of 90840). CMS and most commercial payers apply the ≥50% rule — time must meet threshold.
5. Medical Necessity Statement
Explicitly state why the extended session was medically necessary:
"Extended crisis intervention of 95 minutes was medically necessary to complete safety planning, contact patient's emergency contact, arrange next-day follow-up with prescribing psychiatrist, and ensure patient's immediate safety prior to discharge from the session."
Common Billing Mistakes That Trigger Audits
Here are the patterns that raise red flags with payers — and internal compliance teams:
1. Billing 90840 Without 90839 This gets auto-denied. 90840 is an add-on code. It has no meaning without 90839.
2. Upcoding Difficult Sessions as Crisis If your crisis code frequency is significantly higher than regional benchmarks, payers will notice. Reserve these codes for genuine crises.
3. Missing Time Documentation Without documented start and end times, 90839 and 90840 are indefensible. Add this to your note template as a mandatory field.
4. Billing 90840 With Incompatible Codes Crisis codes cannot be billed on the same day as:
- 90832, 90834, 90837 (standard psychotherapy)
- 90785 (interactive complexity, as a standalone addition)
- 90791/90792 (diagnostic evaluation)
They can be billed with E/M codes by physicians (90839/90840 + 99213, etc.) when separately identifiable medical decision-making is documented.
5. No Documentation of Crisis Severity A note that says "patient was in crisis" is not sufficient. The documentation must demonstrate the crisis, not just name it.
90839 vs. 90837: Know the Difference
One of the most common questions: Why not just bill 90837 (60-minute psychotherapy) for a long, difficult session?
Here's the distinction:
| Factor | 90837 (Psychotherapy 60 min) | 90839 + 90840 (Crisis) | |--------|------------------------------|------------------------| | Clinical context | Scheduled, non-urgent therapy | Urgent psychiatric emergency | | Time threshold | 53+ minutes | 30–74 min (90839), +30 min per 90840 | | Documentation focus | Treatment progress | Crisis severity, risk assessment, safety planning | | Reimbursement | ~$175–$200 Medicare | ~$213+ Medicare (90839 alone) | | Audit risk | Moderate | High — requires strong documentation | | Frequency norms | Can be weekly | Should be relatively rare |
Using 90837 when a genuine crisis occurred is actually under-coding — it doesn't capture the full clinical complexity and under-reimburses you for the actual work performed. Bill what happened. Document what happened. They should match.
Payer-Specific Considerations
Medicare and Medicare Advantage
Medicare covers 90839 and 90840 without prior authorization when medically necessary. Medicare Advantage plans follow Medicare rules but may have additional documentation requirements. Check your specific MA plan contracts.
Medicaid
State-by-state variation is significant. Some states require:
- Prior authorization for crisis codes beyond a certain frequency
- Specific diagnosis codes from the trauma/crisis spectrum (F43.xx, F32.xx with suicidal ideation, etc.)
- Same-day notes submitted electronically within 24 hours
UnitedHealthcare
UHC covers both codes but is known for conducting post-payment audits on crisis codes. Their clinical reviewers look specifically for documented risk assessment tools (Columbia Protocol, PHQ-9, etc.) in the note.
Cigna
Cigna generally follows AMA guidelines but has increasingly flagged crisis codes billed by the same provider more than 2–3 times per patient per year without escalation to higher-level care or additional documentation of clinical rationale.
Aetna
Aetna requires that crisis services be clinically differentiated from scheduled sessions in the documentation. Their policy language specifies the service must be "unscheduled or urgently modified" to qualify.
Diagnosis Codes That Support 90839/90840
Not every diagnosis supports crisis billing. Use ICD-10 codes that reflect the acute, crisis-level presentation:
- F32.2 — Major depressive disorder, severe without psychotic features
- F32.3 — Major depressive disorder, severe with psychotic features
- F43.10 — Post-traumatic stress disorder, unspecified (acute presentation)
- F23 — Brief psychotic disorder
- F41.0 — Panic disorder (when panic attack precipitates genuine crisis)
- T14.91XA — Suicide attempt, initial encounter
- R45.851 — Suicidal ideation
Pair your primary diagnosis with a secondary code that reflects the crisis dimension (e.g., R45.851 as secondary to F32.2).
Audit Defense: Protecting Your Crisis Code Claims
If you're using 90840 regularly, prepare for occasional audits. Here's how to build a defensible record:
- Use structured note templates that include mandatory fields for time, risk assessment, intervention type, and medical necessity statement
- Implement a crisis documentation checklist — Columbia Suicide Severity Rating Scale (C-SSRS) documentation adds significant weight
- Retain collateral contact records — if you called a family member or coordinated with another provider during the crisis, document it
- Keep a session log — track frequency of crisis codes per patient to identify patterns that might look unusual
- Store notes with metadata — timestamp and provider authentication on every note
Frequently Asked Questions
Can I bill 90840 for a telehealth crisis session?
Yes. As of 2024 and carried into 2026, CMS covers 90839 and 90840 via telehealth for Medicare beneficiaries. Most commercial payers have followed suit. Document the telehealth platform used, patient location, and that audio-visual connection was established.
How many units of 90840 can I bill in one session?
There is no hard AMA cap, but billing more than 2 units (90839 + 90840 x2 = 120 minutes total) in a single session will draw scrutiny. If a session exceeds 120 minutes, you must have extremely thorough documentation of medical necessity for the extended time.
Can I bill 90840 if the crisis occurs mid-session?
Yes. If a scheduled therapy session evolves into a genuine crisis requiring extended intervention, you may bill crisis codes — but document the transition point clearly: "At 35 minutes into the scheduled session, patient disclosed active suicidal ideation, at which point the session transitioned to crisis intervention."
Do I need a specific diagnosis to bill 90839/90840?
Not a specific diagnosis, but the diagnosis(es) billed must be consistent with a crisis-level presentation. Billing crisis codes under F41.1 (Generalized Anxiety Disorder) for a patient with no acute risk factors will draw immediate scrutiny.
Can a supervised intern bill 90840?
This depends entirely on your state licensing laws and payer credentialing rules. Most payers require independently licensed providers for crisis billing. Interns billing under a licensed supervisor's NPI in a group practice setting may be permitted by some payers — verify in writing before billing.
Is prior authorization required for 90840?
Generally no for commercial insurance or Medicare, but some Medicaid managed care organizations require prior authorization or same-day telephonic notification for crisis services. Always check your specific payer contracts.
The Bottom Line
CPT code 90840 exists because extended crisis intervention is genuinely different from standard psychotherapy — in clinical intensity, in time, in risk, and in the downstream care coordination it demands. When a patient's safety is on the line, you're doing more than therapy. Your documentation and billing should reflect that reality.
Use the code when it's warranted. Document with specificity. Know your payer rules. And build systems that protect you when an auditor comes knocking.
