90836 CPT Code: Billing, Documentation, and Reimbursement Guide
Psychiatric providers across the United States are facing one of the most challenging billing environments in recent memory. As demand for behavioral health services surges, insurance payers have responded with heightened scrutiny, stricter documentation requirements, and increasingly aggressive claim review processes.
CPT Code 90836 sits at the center of this complexity. As a psychotherapy add on code used alongside evaluation and management services, it offers significant revenue potential but only when billed correctly. Even minor documentation gaps or timing errors can trigger costly denials, audits, and recoupment demands.
This guide was developed by behavioral health billing specialists to give psychiatrists, psychiatric nurse practitioners, and behavioral health organizations a clear roadmap for billing 90836 with confidence. Whether you are trying to reduce claim denials, improve documentation quality, or recover lost revenue, this resource was built for you.

Quick Answer: What is CPT Code 90836?
CPT Code 90836 is an add on psychotherapy code used to report 30 to 52 minutes of individual psychotherapy provided on the same day as an evaluation and management (E/M) service. It cannot be billed as a standalone service.
CPT 90836 was established to allow psychiatric providers to document and bill for the distinct psychotherapy component delivered during a combined medical and therapeutic visit. When a psychiatrist conducts a medication management visit and also provides structured psychotherapy, the psychotherapy time qualifies for a separate add on code.
The code is reported in addition to a primary E/M code such as an office visit code. It recognizes that psychiatrists routinely perform two distinct clinical functions in a single encounter and should be reimbursed appropriately for both.
Did You Know? Behavioral health providers who correctly implement 90836 as part of their billing workflow can increase per visit collections by 30 to 50 percent compared to billing E/M codes alone.
Yes. CPT 90836 is classified as an add on code in the AMA CPT codebook, which means it must always be billed alongside a primary service. It cannot stand alone on a claim.
The primary codes most commonly paired with 90836 are office or outpatient evaluation and management services including new patient codes 99202 through 99205 and established patient codes 99212 through 99215. The qualifying primary service must reflect a medically necessary E/M encounter separate from the psychotherapy component.
COMPLIANCE ALERT: Billing 90836 without a valid primary E/M code on the same claim is one of the most common errors that triggers automatic denial. Always verify the primary code is present before submission.
Quick Answer: How much psychotherapy time is required for CPT Code 90836?
CPT 90836 requires between 30 and 52 minutes of individual psychotherapy time. This time must be clearly documented separately from the E/M component of the visit.
Time documentation for 90836 is one of the most scrutinized elements during payer audits. Providers must record the specific start and stop time of the psychotherapy portion of the visit, or clearly document the total psychotherapy minutes in the progress note.
The psychotherapy time must be clinically distinct from the time spent on the E/M service. Many providers mistakenly count overlapping time, which is a significant compliance risk. The rule is straightforward: the psychotherapy minutes and the E/M minutes cannot be the same minutes.
- Document total psychotherapy minutes explicitly in the note
- Record start and stop times whenever possible for audit protection
- Do not count time spent on medication review toward psychotherapy minutes
- Confirm that total visit time is consistent with the primary E/M code selected
The following table outlines the primary E/M codes most frequently paired with 90836 and key billing considerations for each scenario.
| Primary Code | Description | Clinical Scenario | Documentation Requirement | Revenue Impact |
|---|---|---|---|---|
| 99202 | New patient, low complexity | Initial psychiatric assessment, straightforward presentation | History, exam, low complexity MDM or 15 to 29 min total time | Adds 30 to 52 min psychotherapy revenue to E/M base |
| 99203 | New patient, moderate complexity | New patient with anxiety or depression requiring therapeutic support | History, exam, moderate MDM or 30 to 44 min total time | Strong combined billing opportunity |
| 99204 | New patient, moderate high complexity | New patient with multiple behavioral diagnoses | History, exam, moderate MDM or 45 to 59 min total time | High revenue encounter with add on |
| 99205 | New patient, high complexity | Complex new patient with co-occurring conditions | History, exam, high MDM or 60 to 74 min total time | Maximum new patient revenue potential |
| 99212 | Established patient, minimal complexity | Routine medication check with brief supportive counseling | 2 of 3 key elements or 10 to 19 min total time | Low base but add on boosts collections |
| 99213 | Established patient, low complexity | Follow up with symptom adjustment and therapy | 2 of 3 key elements or 20 to 29 min total time | Common pairing with significant revenue gain |
| 99214 | Established patient, moderate complexity | Follow up with complex medication titration and therapy | 2 of 3 key elements or 30 to 39 min total time | High frequency high value pairing |
| 99215 | Established patient, high complexity | Complex established patient with multiple active conditions | 2 of 3 key elements or 40 to 54 min total time | Highest per visit revenue with add on |
Provider Checklist for Audit Readiness
Every 90836 claim must be supported by documentation that demonstrates medical necessity, clinical appropriateness, and the distinct nature of the psychotherapy service. The checklist below covers the minimum requirements for audit ready documentation.
- Presenting psychiatric symptoms clearly documented
- Medical necessity for psychotherapy explicitly stated
- Psychotherapy technique or modality used (e.g., CBT, supportive therapy)
- Specific psychotherapy interventions described
- Patient response to interventions during the session
- Progress toward established treatment goals
- Mental status examination findings
- Current psychiatric diagnoses with DSM codes
- Psychotherapy time clearly documented in minutes
- Total visit time and E/M time separately documented
- Provider credentials and supervising provider information where applicable
- Plan for continued treatment with goals and timelines
COMPLIANCE ALERT: Vague progress notes such as 'patient doing well, continue current medications' do not support an 90836 claim. Documentation must describe the psychotherapy process in clinical detail.

CPT Code 90836 Compared With Other Psychotherapy Codes
| Code | Purpose | Typical Duration | Clinical Use | Add On? | Revenue Potential |
|---|---|---|---|---|---|
| 90832 | Individual psychotherapy | 16 to 37 minutes | Standalone brief therapy session | No | Low to moderate |
| 90833 | Psychotherapy add on (brief) | 16 to 37 minutes | With E/M service, shorter session | Yes | Moderate |
| 90834 | Individual psychotherapy | 38 to 52 minutes | Standalone medium length session | No | Moderate |
| 90836 | Psychotherapy add on (medium) | 30 to 52 minutes | With E/M service, medium session | Yes | Moderate to high |

| 90838 | Psychotherapy add on (extended) | 53 or more minutes | With E/M service, extended session | Yes | Highest |
1. Insufficient Psychotherapy Documentation
The most common denial trigger is vague or incomplete
documentation. When progress notes fail to describe the psychotherapy process
in clinical detail, payers reject the claim for lack of medical necessity.
• Why it happens: Time pressure leads to templated or
copied notes
• Financial impact: Full claim denial, often on 15 to 30
percent of 90836 submissions
• Best practice: Use structured note templates with
psychotherapy specific fields
2. Incorrect Time Reporting
Reporting 90836 when the actual psychotherapy time was under
30 minutes or over 52 minutes results in automatic code mismatch. Many
providers round up or estimate time rather than documenting accurately.
• Why it happens: Providers do not track psychotherapy
time distinctly from E/M time
• Financial impact: Denial or downcoding to 90833 which
carries a lower reimbursement
• Best practice: Train clinical staff to document
psychotherapy minutes in real time
3. Using the Code Without a Qualifying Primary
Service
Submitting 90836 without a valid E/M code on the same date of
service will result in rejection at the claims processing level before it even
reaches a reviewer.
• Financial impact: 100 percent claim rejection with
delayed revenue
• Best practice: Use claim scrubbing software to verify
add on code pairing before submission
4. Medical Necessity Issues
Some payers require explicit documentation that psychotherapy
was medically necessary and not just a patient preference. Without clear
clinical justification, claims face medical necessity denials.
5. Modifier Errors
Adding incorrect modifiers or omitting required modifiers on
90836 claims is a frequent source of denial in managed care environments.
Always review payer specific modifier requirements before submission.
Denial prevention requires a systematic approach that starts before the clinical encounter and continues through payment posting. The following strategies are proven to reduce 90836 denial rates for behavioral health practices.
• Conduct eligibility verification and prior auth checks before every visit
• Use structured psychotherapy note templates that include all required elements
• Train providers on proper time documentation for E/M and psychotherapy components
• Implement claim scrubbing software that flags add on code errors before submission
• Review explanation of benefits documents to identify denial patterns by payer
• Build a denial management workflow with automatic follow up timelines
• Appeal every inappropriate denial with supporting clinical documentation
• Track denial rates by code and payer to identify systemic problems

CPT 90836 is a code that receives frequent attention from
Medicare contractors and private payer audit teams. The add on nature of the
code combined with psychotherapy documentation requirements creates multiple
audit risk points.
Key Audit Triggers
• High frequency of 90836 paired with 99215 (highest
level E/M)
• Identical or copy pasted progress notes across multiple
dates of service
• Absence of documented psychotherapy time in progress
notes
• Billing 90836 without corresponding therapy diagnosis
codes
• Provider specialty mismatch with psychotherapy billing
Compliance Best Practices
• Conduct internal chart audits every quarter
specifically targeting 90836 claims
• Maintain documentation that clearly distinguishes E/M
time from psychotherapy time
• Ensure progress notes are individualized and reflect
each unique clinical session
•
Keep signed treatment plans on file that support the
ongoing medical necessity of psychotherapy
• Review OIG Work Plan each year for behavioral health
billing focus areas
COMPLIANCE
ALERT: Routine self audits of
90836 documentation reduce the financial risk of payer audits and protect
providers from recoupment demands that can reach tens of thousands of dollars.

Interactive Revenue Impact Example
The following example shows how documentation errors on 90836
claims can significantly reduce monthly collections for a busy psychiatric
practice.
Scenario | Monthly | 90836 Rate | Denial Rate | Monthly | Annual |
Optimized billing | 200 | $85 | 5% | $16,150 | $193,800 |
Common errors present | 200 | $85 | 25% | $12,750 | $153,000 |
Revenue lost to denials |
|

This example illustrates that a 20 percent improvement in
denial rates on 90836 claims generates over 40,000 dollars in recovered revenue
annually for a practice seeing 200 patients monthly.
