01.  Introduction: The Revenue Most Psychiatric Practices Are Missing

Here's a scenario that plays out in psychiatric practices across the country every single day: a psychiatrist sees an established patient for 30 minutes. The first 15 minutes covers medication review, side effect management, and a brief medical assessment. The next 15 minutes shifts into supportive psychotherapy exploring the patient's current stressors, reinforcing coping strategies, and adjusting the therapeutic approach based on treatment progress. Two distinct clinical services happened in that visit. Most practices bill only one.

CPT 90833, 90836, and 90838 are the add-on codes that capture the psychotherapy component of combined E/M and psychotherapy visits. They are add-on codes, meaning they attach to the E/M service code rather than replacing it and they allow psychiatrists, PMHNPs, and other prescribing behavioral health providers to appropriately bill for both services when both services genuinely occurred and are separately documented.

The financial impact of correctly using these codes is significant. A psychiatric practice that misses 90833 on 10 combined visits per day loses approximately $790 in daily Medicare revenue roughly $197,500 per year at a 250-day schedule. And that's at Medicare rates. Commercial payer rates for these codes are typically higher. For many psychiatric practices, this is not a marginal billing issue it's one of the largest uncaptured revenue opportunities in their practice.

This guide covers every aspect of billing 90833, 90836, and 90838 correctly in 2026: the time thresholds, the documentation requirements, what "separately identifiable" actually means in practice, and how to prevent the denials that follow when these codes are billed without sufficient documentation support.

90833 Add-On: E/M + Psychotherapy (~30 min)

90836 Add-On: E/M + Psychotherapy (~45 min)

90838 Add-On: E/M + Psychotherapy (~60 min)

02.  Quick Summary: CPT 90833, 90836 & 90838 At a Glance

⚡  The Add-On Code Rule — Read This First

Add-on codes (90833, 90836, 90838) are NEVER billed alone.  They always accompany an E/M service code (99202–99215) on the same claim. The E/M is the primary code; the psychotherapy add-on is appended. If only psychotherapy was provided no medication management, no medical evaluation use standalone codes (90832, 90834, 90837) instead.

Also critical:  Therapists (LCSWs, LPCs, LMFTs) and psychologists without prescriptive authority CANNOT bill 90833, 90836, or 90838. These codes require a provider who can deliver both E/M services and psychotherapy which means prescribers only.

03.  Understanding Psychotherapy Add-On Codes — Why They Exist

Before the AMA's 2013 restructuring of behavioral health CPT codes, psychiatrists faced a frustrating billing dilemma: when a visit included both medication management and psychotherapy, billing rules required choosing one or the other in most circumstances. The psychotherapy add-on codes (90833, 90836, 90838) were introduced to eliminate that dilemma to create a billing structure that accurately reflects what actually happens in many psychiatric appointments.

The clinical reality is that medication management visits and psychotherapy are not always separable events. A psychiatrist who reviews a patient's response to a medication adjustment, assesses side effects, addresses emerging safety concerns, and then transitions into a therapeutic discussion about the psychological factors driving the patient's symptoms is delivering two distinct clinical services in a single appointment. These codes allow that clinical reality to be captured in the billing.

CMS and the AMA are explicit about the intent: the E/M service must be a significant, separately identifiable service from the psychotherapy. Both components must be medically necessary. Both must be separately documented. And the time spent in each component must be distinguishable in the clinical record. This is not a formality — it is the standard that payers apply when reviewing claims for these codes.

💡  The Clinical Scenarios Where Add-On Codes Apply

▸  Psychiatrist performs medication review and adjustment (E/M), then transitions to supportive psychotherapy addressing treatment adherence and psychosocial stressors

▸  PMHNP conducts a medical evaluation for a new medication, then provides psychoeducation and therapeutic skill-building for the same patient

▸  Psychiatrist addresses a mental health crisis from a medical decision-making perspective (suicidality risk assessment, medication modification), then provides brief CBT intervention

▸  Prescribing behavioral health provider conducts scheduled E/M for stable patient and extends the session to address a therapeutic crisis that requires clinical psychotherapy intervention

04.  Full Comparison Table: 90833 vs 90836 vs 90838

Here is the complete side-by-side comparison across every billing-relevant dimension for the three psychotherapy add-on codes:

05.  Time Requirement Timeline — Which Code Applies When

The psychotherapy add-on codes are time-based the code selected must match the actual documented face-to-face psychotherapy time within the visit. This is the psychotherapy time only, not the total visit time and not the E/M time. Both components happen in the same visit; only the psychotherapy portion drives the add-on code selection.

⏱️  Time Measurement Rules for Add-On Codes

What counts as psychotherapy time:  Direct face-to-face clinical interaction where psychotherapy is being delivered therapeutic conversation, skill-building, processing, behavioral intervention

What does NOT count:  Medication review, prescription writing, medical history taking, documentation time, pre-visit preparation, non-therapeutic conversation

Documentation requirement:  Document the psychotherapy start and end time separately from the overall visit time. "Patient seen for 45 minutes, including 20 minutes of supportive psychotherapy" is far better than "45-minute combined visit."

06.  Complete Documentation Checklist E/M AND Psychotherapy Components

The most common reason add-on code claims are denied or recouped in audits is that the documentation doesn't clearly support two separately identifiable services. Both the E/M component and the psychotherapy component must have their own documentation within the same clinical note. Here is what that complete documentation looks like:

E/M Component Checklist (Required for Primary Code)

✓  Chief complaint and reason for medication management visit

✓  Medication review — current medications, dosages, compliance, and effectiveness

✓  Side effect assessment and response

✓  Mental status examination relevant to medical decision making

✓  Medical decision making documentation supporting the selected E/M level (or total time if billing by time)

✓  Risk assessment from a medical perspective (suicidality, self-harm, medication safety)

✓  Medication plan — continuation, modification, new prescriptions, or discontinuation with clinical rationale

✓  Provider signature with credentials confirming prescriptive authority

Psychotherapy Component Checklist (Required for Add-On Code)

✓  Clear transition notation identifying when psychotherapy began (start time of psychotherapy component)

✓  Chief complaint or presenting focus for the psychotherapy component (may differ from E/M focus)

✓  Therapeutic interventions used — CBT, DBT, motivational interviewing, supportive therapy, psychoeducation with specific techniques noted

✓  Progress toward established psychotherapy treatment goals since last session

✓  Patient response to interventions during this session

✓  Medical necessity statement for ongoing psychotherapy — why this patient requires psychotherapy in addition to medication management

✓  End time of psychotherapy component (total face-to-face psychotherapy time clearly stated)

✓  Plan for next psychotherapy session — goals, topics, homework if applicable

🚨  The "Separately Identifiable" Documentation Standard

CMS and payers require that the E/M service be significant and separately identifiable from the psychotherapy. In practice, this means your clinical note must make it evident to a reviewer that two distinct clinical activities occurred not that medication questions and therapeutic discussion were blended together in a single undifferentiated narrative. Some practices use separate subsections labeled "Medical Management" and "Psychotherapy" within the same note. Others write two consecutive, clearly separated documentation blocks. Either approach works what doesn't work is a single merged note with no distinction between the clinical components.

07.  When Can These Codes Be Billed? Proper vs. Improper Scenarios

08.  Common Billing Mistakes — Warning Table

These are the errors Sirius Solutions Global's psychiatric billing specialists encounter most often when auditing or onboarding new psychiatry clients. Each one either reduces revenue, creates audit exposure, or both:

09.  Documentation Example: Poor Note vs. Billing-Ready Note

The difference between a note that supports add-on code billing and one that doesn't is rarely about clinical content it's about how that content is organized and documented. Here's a concrete example:

Poor Documentation (Fails Add-On Code Review)	Billing-Ready Documentation (Supports 90833 + E/M)
"Patient seen for 30 minutes. Doing better on current medication regimen. Side effects manageable. Discussed stress at work and coping strategies. Continue current medication. Follow up in 4 weeks."	[MEDICAL MANAGEMENT — 15 min] Patient reports tolerating sertraline 100mg with mild initial nausea now resolved. No new side effects. PHQ-9: 10 (down from 14). Reviewed medication response; decided to continue current dose. Discussed sleep hygiene given residual insomnia. PLAN: Continue sertraline 100mg; reassess at next visit.
Why this fails: No separation of services, no documentation of psychotherapy time, no distinction between medication management and psychotherapy content, no clinical interventions identified, cannot determine if 90833 threshold was met.	[PSYCHOTHERAPY — 16 min — Start 2:15pm, End 2:31pm] Patient presented ongoing work-related stressors contributing to depression. Employed CBT thought-challenging technique targeting catastrophic thinking patterns around job performance. Patient identified three cognitive distortions; developed counter-statements. Progress toward goal: improved thought monitoring. PLAN: Practice thought records daily; continue CBT focus on work stressors next session.
This note cannot support 90833 billing. If audited, the add-on code would be denied and recouped.	This note clearly documents two separately identifiable services with distinct clinical content, documented psychotherapy time (16 min = qualifies for 90833), and supports both the E/M and add-on code. This note survives an audit.

10.  Revenue Optimization Tips for Psychiatric Practices

Correctly billing 90833, 90836, and 90838 is not about billing more aggressively it's about capturing revenue for services that are genuinely being delivered. Here are the most impactful optimization strategies for psychiatric practices in 2026:

11.  Payer Considerations: Medicare, Medicaid & Commercial Insurance

Not every payer handles add-on psychotherapy codes the same way. Before billing 90833, 90836, or 90838, verify coverage and documentation requirements with each specific payer. Here's a general overview by payer type:

Payer Type	Coverage of 90833/90836/90838	Documentation Standard	Key Considerations for 2026
Medicare	Covered — all three codes active under CMS	Separate E/M and psychotherapy documentation required; time documented	Mental health parity rules apply; psychiatric coding LCDs from your MAC should be reviewed annually
Medicaid	Varies significantly by state; some states do not cover add-on codes	State-specific; some states require prior auth or session limits	Verify with your state's Medicaid program or managed care plan before billing; do not assume coverage
Commercial Insurance	Most major commercial payers cover add-on codes; rates vary by contract	Generally follow CMS documentation standards; some require PA for ongoing combined visits	Review your EOBs for systematic underpayment on add-on codes; renegotiate if contracted rate is below Medicare
Medicare Advantage	Same codes as Medicare; plan-specific rules may apply	MA plans may have additional documentation requirements	Verify with each MA plan — some apply stricter medical necessity review than traditional Medicare

⚠️  Compliance Alert: Always Verify Before Billing

Payer policies for behavioral health codes change more frequently than most other specialties. The coverage and documentation requirements for 90833, 90836, and 90838 that applied in 2024 may have changed. Before billing these codes, review the relevant Local Coverage Determination (LCD) from your Medicare Administrative Contractor, verify your state's Medicaid policy, and check the behavioral health billing manual for each commercial payer you contract with. When in doubt, contact the payer's provider relations line directly.

12.  FAQ — 12 Most-Asked Questions About CPT 90833, 90836 & 90838

These are the most-searched questions about psychotherapy add-on codes in 2026 — answered directly for psychiatrists, PMHNPs, billing managers, and practice owners.

Q1: What are CPT 90833, 90836, and 90838?

CPT 90833, 90836, and 90838 are add-on codes for individual psychotherapy provided in the same visit as an Evaluation and Management service. They are appended to an E/M code (not billed alone) when a prescribing behavioral health provider delivers both medical evaluation/management and individual psychotherapy in a single encounter. 90833 covers approximately 30 minutes of psychotherapy (16-37 min), 90836 covers approximately 45 minutes (38-52 min), and 90838 covers approximately 60 minutes (53+ min).

Q2: Who can bill CPT 90833, 90836, and 90838?

Only providers who can deliver both E/M services and psychotherapy can bill these add-on codes. This includes psychiatrists (MDs, DOs), psychiatric mental health nurse practitioners (PMHNPs), and physician assistants with a psychiatric scope of practice. Therapists (LCSWs, LPCs, LMFTs) and psychologists without prescriptive authority cannot bill these codes because they are not authorized to provide E/M services.

Q3: What is the difference between 90833 and 90832?

90832 is a standalone psychotherapy code for a 30-minute individual therapy session (16-37 min). It is used when only psychotherapy is provided — no medication management or medical evaluation. 90833 is an add-on code covering the same time range of psychotherapy (16-37 min) but appended to an E/M code when both services are provided in the same visit. A non-prescriber would use 90832; a prescriber who provided both E/M and psychotherapy would use the appropriate E/M code + 90833.

Q4: Can I bill an E/M code and a standalone psychotherapy code on the same day?

Generally no. When both E/M services and psychotherapy are provided in the same session by the same provider, you must use the add-on code structure (E/M + 90833/90836/90838) rather than billing a standalone E/M and a standalone psychotherapy code separately. Billing both a standalone E/M code and a standalone psychotherapy code for the same patient on the same date by the same provider triggers NCCI bundling edits and will result in automatic denial.

Q5: How do I document the psychotherapy component to support add-on code billing?

The psychotherapy documentation must be clearly separate from the E/M documentation within the same note. At minimum, your psychotherapy documentation should include: the start and end time of the psychotherapy component specifically, the presenting focus of the psychotherapy (which may differ from the E/M chief complaint), the therapeutic interventions used with enough clinical detail to demonstrate active treatment, the patient's response and progress toward treatment goals, and a plan for the next psychotherapy session. The note must make it evident to a reviewer that psychotherapy was a distinct, intentional clinical activity — not incidental supportive conversation during medication management.

Q6: What is the minimum psychotherapy time required to bill add-on codes?

The minimum documented psychotherapy time to use any add-on code is 16 minutes. Less than 16 minutes of psychotherapy within a combined visit does not qualify for add-on code billing under any of the three codes. For 90833: 16-37 minutes. For 90836: 38-52 minutes. For 90838: 53 minutes or more. The time refers to face-to-face psychotherapy interaction only — not the total visit time or the E/M time.

Q7: Can a PMHNP bill 90836 with a 99214?

Yes. A psychiatric mental health nurse practitioner (PMHNP) who delivers both an E/M service (such as medication management billable as 99214) and 38 to 52 minutes of individual psychotherapy in the same visit can bill 99214 + 90836, provided both services are separately documented, both are medically necessary, and the psychotherapy time is explicitly recorded. The PMHNP must have both prescriptive authority and authorization to provide psychotherapy within their scope of practice and state licensure.

Q8: Are there prior authorization requirements for add-on psychotherapy codes?

Prior authorization requirements vary significantly by payer. Medicare typically does not require prior authorization for psychotherapy add-on codes, though coverage is subject to medical necessity. Many commercial payers do require prior authorization for ongoing combined E/M and psychotherapy visits, particularly after the initial sessions. Medicaid PA requirements vary by state and managed care plan. Always verify prior authorization requirements with each payer before initiating a combined visit billing pattern for new patients.

Q9: Can these codes be billed for telehealth visits?

Yes. CPT 90833, 90836, and 90838 are eligible for telehealth billing when combined with an appropriate telehealth E/M code. Apply the correct telehealth modifier: modifier -95 for most commercial payers and modifier -GT for Medicare (though CMS has been transitioning modifier requirements — verify with your MAC). Also confirm the correct Place of Service code: POS 10 for patient home telehealth, POS 02 for telehealth at a health facility. Documentation requirements are identical to in-person visits.

Q10: What happens if my documentation doesn't support the add-on code I billed?

If payer review or an audit determines that your documentation does not support the add-on code billed, the likely outcomes include: denial of the add-on code (with or without payment of the E/M component), a request for repayment of previously paid add-on claims, and in cases of pattern billing without adequate documentation, referral for a more comprehensive audit or a compliance review. Post-payment audits that find add-on code documentation deficiencies often look back multiple years. Maintaining complete, audit-ready documentation is the most effective protection.

Q11: Which payer pays the most for 90838 in a combined visit?

Commercial payers typically reimburse at higher rates than Medicare for add-on psychotherapy codes. The highest rates for 90838 are generally found in commercial contracts with major insurers in high-cost-of-living markets. Medicare's national approximate rate for 90838 is ~$145 non-facility, but commercial contracts may pay significantly more. Review your current fee schedule and EOBs to identify which payers are reimbursing below Medicare and which are reimbursing competitively this data is valuable for contract renegotiation.

Q12: How can a behavioral health billing specialist help with 90833/90836/90838 billing?

A behavioral health billing specialist helps with add-on code billing in several ways: conducting documentation audits to identify combined visits where add-on codes were not billed, reviewing note structures to ensure documentation meets the "separately identifiable" standard, verifying payer-specific coverage and authorization requirements, submitting claims with correct code combinations and modifiers, managing denials with targeted appeals, and monitoring for payer pattern audits that target add-on code utilization rates. For psychiatric practices new to add-on code billing, a professional review before the first submission reduces audit risk significantly.
