Ultimate Guide to Medical Billing Top Reasons Claims Get Denied and How to Fix Them Fast
Psychiatric practices across the United States face mounting pressure every billing cycle. Documentation complexity, payer scrutiny, and rising administrative burdens are squeezing reimbursement and creating revenue gaps that add up fast. For providers reporting CPT Code 90838, the stakes are especially high.
This add on code is tied directly to the level of service your psychiatrist or psychiatric nurse practitioner provides during combined evaluation and psychotherapy sessions. When it is billed correctly, it captures real revenue. When it is billed incorrectly or left off the claim entirely, your practice loses money every single day.
Behavioral health clinics, solo psychiatric providers, and large health systems alike are leaving significant reimbursement on the table due to documentation gaps, incorrect time reporting, and missing medical necessity statements. Insurance carriers are paying closer attention than ever, and audit risk has never been higher.
This guide was built for psychiatrists, psychiatric nurse practitioners, behavioral health clinic managers, and revenue cycle teams who want clear answers and practical billing strategies for CPT 90838.
What Is CPT Code 90838?
Quick Answer Box
CPT Code 90838 is a psychotherapy add on code used when a psychiatrist or qualified provider performs 60 or more minutes of psychotherapy during the same session as an evaluation and management service. For accurate claim execution, solutions provided by Care RCM ensure it is never billed alone and always accompanies a primary E/M code.
CPT Code 90838 represents 60 or more minutes of psychotherapy delivered in addition to a primary evaluation and management service. It was created to reflect the clinical reality of psychiatric practice, where providers routinely combine medication management with therapeutic intervention in a single encounter.
The American Medical Association defines this code specifically for use in combination with office or outpatient E/M codes. It captures the additional work and clinical complexity involved when a provider moves beyond medication review to deliver structured psychotherapy within the same visit.
This code is clinically significant because it reflects a higher level of care. When a psychiatrist addresses both the biological and psychological dimensions of a mental health condition in one session, 90838 provides the mechanism to report that additional psychotherapy work and receive appropriate reimbursement for it.
- Official AMA description: Psychotherapy, 60 minutes with patient when performed with an evaluation and management service (List separately in addition to the code for primary procedure)
- Must be reported in addition to a primary E/M code
- Requires a minimum of 53 minutes of psychotherapy
- Can be billed by psychiatrists and other qualified mental health professionals authorized by their payer
Yes. CPT Code 90838 is an add on code by definition. It cannot stand alone on a claim and must always be paired with a qualifying primary evaluation and management code. Submitting 90838 without a primary code will result in an automatic denial.
The add on structure exists because the psychotherapy service described by 90838 occurs alongside and in addition to a medical service. The provider must have a legitimate reason to see the patient for both medication management and psychotherapy during the same encounter.
Payers including Medicare, Medicaid, and commercial carriers all require the presence of a primary E/M code before they will process 90838. Some managed care plans have additional requirements around prior authorization and provider credentialing that must be verified before submission.
CPT Code 90838 Time Requirements
Compliance Alert
CPT Code 90838 requires a minimum of 53 minutes of psychotherapy within the session. If the psychotherapy time documented falls below 53 minutes, use CPT 90836 instead (45 minutes with E/M). Relying on specialized documentation guidance from Care RCM helps avoid using 90838 when the documented time does not meet the threshold, preventing compliance risk and audit exposure.
Time is one of the most critical factors in correctly reporting CPT Code 90838. The code requires that the psychotherapy portion of the session reach a minimum of 53 minutes, not the total session time.
The documentation must separately capture the time spent on the evaluation and management component and the time spent on psychotherapy. These are distinct services with distinct documentation expectations. Combining them into a general total time note is not sufficient and creates significant audit risk.
Common timing mistakes that lead to denials include documenting total session time without specifying psychotherapy time, rounding up psychotherapy time to meet the 90838 threshold, and failing to document start and end times for the psychotherapy portion.

CPT 90838 Compared With Other Psychotherapy Add On Codes

1. Insufficient Psychotherapy Documentation
Why it happens: Providers document the E/M service thoroughly but write only a brief sentence about psychotherapy without describing the interventions, the patient response, or the therapeutic goals.
Financial impact: Payers deny the add on code and request medical records for review. Repeated denials result in write offs and lost revenue.
Best practice: Use a structured therapy note template that forces documentation of modality, technique, patient engagement, and treatment goal progress.
2. Incorrect Time Reporting
Why it happens: Providers estimate session time without recording start and stop times. Some round up to reach the 53 minute threshold for 90838 when the actual therapy time was closer to 45 minutes.
Compliance concern: This creates false billing risk and potential fraud liability during payer audits.
Best practice: Use an EHR with built in time tracking. Document exact start and stop times for both the E/M and therapy portions.
3. Billing 90838 Without a Qualifying Primary E/M Code
Why it happens: Billing staff may not understand the add on code requirement, or E/M codes are dropped during the claim scrubbing process.
Best practice: Set up claim edits in your billing system to flag any claim with 90838 that does not include a paired E/M code.
4. Medical Necessity Issues
Why it happens: Notes do not explain why the combined E/M and psychotherapy service was necessary for that specific patient at that specific visit.
Best practice: Train providers to include one or two sentences in every combined session note that tie the clinical presentation directly to the decision to provide psychotherapy alongside medication management.
5. Modifier Errors and Missing Modifiers
Why it happens: Payer requirements for modifiers on add on codes change and not all practices track those changes proactively.
Best practice: Conduct an annual payer policy review and update your billing team on any modifier requirements specific to 90838.
Reducing denials for CPT Code 90838 starts with a systematic approach to documentation, billing, and payer management. The following strategies have the highest impact.

Compliance Alert
The OIG Work Plan consistently identifies behavioral health billing, including psychotherapy add on codes, as a focus area for audits. Providers who cannot produce complete documentation to support 90838 face recoupment demands, exclusion risk, and reputational harm.
Audit readiness means your documentation, billing practices, and compliance policies can withstand scrutiny at any time. For CPT Code 90838, audit triggers commonly include high frequency use of 90838 compared to peers, patterns of billing 90838 with high level E/M codes on nearly every claim, and claims lacking separate time documentation for psychotherapy.
Your compliance program should include periodic internal audits of 90838 claims, a documentation standards manual for all providers, a clear corrective action process for identified errors, and regular training for both clinical and billing staff.
Managing CPT Code 90838 billing in house is possible, but it places a heavy burden on your administrative team and exposes your practice to unnecessary risk. Professional behavioral health billing services bring specialized expertise that translates directly into better financial outcomes.

The behavioral health sector is growing faster than almost any other specialty. Demand for psychiatric services continues to rise, and payers are under pressure to expand coverage while also managing costs. That tension creates a difficult environment for providers who are not proactive about their billing operations.
In 2026, several trends are shaping psychiatric reimbursement. Telehealth services for behavioral health remain covered by most major payers, and the documentation standards for 90838 apply equally to in person and virtual encounters. Automation and AI tools in revenue cycle management are reducing claim errors and accelerating payment cycles for practices that adopt them.
At the same time, payer audits of behavioral health claims are increasing. Providers who rely on outdated billing practices or under invest in documentation training are seeing higher denial rates and longer collection timelines. The practices that will thrive are those that treat billing as a clinical quality issue, not just an administrative task.

Revenue Loss Scenario
Suppose a psychiatric practice sees 80 patients per month who qualify for CPT 90838. If 25 percent of those claims are denied due to documentation errors, and the average reimbursement for 90838 is $90, the practice loses $1,800 per month or $21,600 per year. Add in the time spent on denials management and the true cost is even higher.
