For busy clinicians, navigating the complexities of medical billing codes can be a significant source of administrative burden. The CPT code 90833, which covers a 30-minute psychotherapy session conducted during a medical visit, is a prime example. While it offers a valuable way to bill for integrated care, its nuances often lead to confusion and billing errors. This comprehensive guide, inspired by real-world questions from medical forums and Reddit, provides a clinically accurate, SEO-optimized listicle to help you master the 90833 CPT code and ensure you're properly reimbursed for your work.
CPT code 90833 is an add-on code, meaning it must be billed in conjunction with an Evaluation and Management (E/M) service. It is specifically for a psychotherapy session lasting between 16 and 37 minutes that is provided by the same clinician on the same day as the E/M service. Think of it as a "combo code" for when you're addressing both a patient's medical and mental health needs in a single visit. For example, if you're a psychiatrist managing a patient's medication for depression (the E/M service) and you also provide 25 minutes of cognitive behavioral therapy (CBT) to address their anxiety, you would use both the appropriate E/M code and the 90833 add-on code.
This code is typically used by medical professionals who are licensed to provide both E/M services and psychotherapy. This includes:
It's important to note that non-prescribing therapists, such as Licensed Clinical Social Workers (LCSWs), Licensed Marriage and Family Therapists (LMFTs), and Licensed Professional Counselors (LPCs), do not typically use this code as they do not bill for E/M services. They would use standalone psychotherapy codes like 90832, 90834, or 90837.
Thorough and accurate documentation is the cornerstone of successful billing for CPT code 90833. Your notes must clearly distinguish between the E/M service and the psychotherapy session to justify the use of both codes. Here are some best practices to follow:
Consider using a documentation template that includes these elements to ensure consistency and completeness. You can also explore how AI scribes can help you generate accurate and compliant documentation, freeing up your time to focus on patient care.
Even with a good understanding of the code, it's easy to make mistakes that can lead to claim denials or audits. Here are some of the most common pitfalls and how to avoid them:
Common mistakes
How to avoid it
Forgetting the Modifier 25
Always append the -25 modifier to the E/M code to indicate that a significant, separately identifiable E/M service was provided on the same day as the psychotherapy.
Insufficient Time
Ensure the psychotherapy portion of the visit is at least 16 minutes long. Anything less does not qualify for the 90833 code.
Vague Documentation
Avoid generic phrases like "provided therapy." Be specific about the interventions used and the patient's response.
Billing for Non-Therapeutic Conversations
A quick chat about the patient's day does not qualify as psychotherapy. The session must be a structured therapeutic intervention.
To further streamline your billing process, consider using tools like S10.AI , Grammarly to ensure your documentation is clear and professional, and S10.AI/ Zapier to automate tasks between your E/M and billing software.
It's important to understand that the reimbursement for 90833 is often lower than for standalone psychotherapy codes. This is because it's an add-on code, and the primary reimbursement comes from the E/M service. However, using 90833 can still significantly increase the overall reimbursement for a visit that includes both medical management and psychotherapy. Reimbursement rates can vary widely depending on the payer and your geographic location. Here's a sample table of average reimbursement rates, but be sure to check with your specific payers for their fee schedules:
Payer
Average Reimbursement Rate for 90833
Medicare
$85 - $100
Medicaid
$70 - $85
Private Insurance
$90 - $110

What specific documentation is required for CPT code 90833 to be audit-proof?
To ensure your documentation for CPT code 90833 is robust and can withstand an audit, it is critical to clearly separate the Evaluation and Management (E/M) service from the psychotherapy component. Your note must explicitly state the exact time spent on psychotherapy—at least 16 minutes is required—and should detail the therapeutic techniques used, such as cognitive-behavioral therapy (CBT), motivational interviewing, or supportive therapy. Vague descriptions are a common red flag. The documentation must also connect the psychotherapy to the patient's overall treatment plan, demonstrating medical necessity. Consider implementing structured documentation templates or explore how AI scribes can help ensure these specific elements are captured accurately for every visit, reducing your risk during payer reviews.
When should I use the 90833 add-on code instead of just a standard E/M code like 99214?
You should use the 90833 add-on code only when you provide a distinct and significant psychotherapy service in addition to the primary E/M service on the same day. If the visit is solely for medication management with brief, supportive check-ins, a standard E/M code like 99213 or 99214 is more appropriate. The key determinant is whether you dedicate at least 16 minutes to a structured therapeutic intervention aimed at addressing the patient's mental health condition. Simply discussing symptoms does not qualify. Learn more about your practice's billing patterns to see if you are under-coding visits where significant psychotherapy occurs, as properly using 90833 ensures fair reimbursement for integrated care.
As a PMHNP, can I bill for CPT code 90833 if I provide supportive therapy during a medication management visit?
Yes, as a Psychiatric-Mental Health Nurse Practitioner (PMHNP), you can bill for CPT code 90833, provided the service is within your scope of practice and properly documented. Many PMHNPs and psychiatrists on forums like Reddit discuss the ethics and requirements of this. The core requirement is that you must deliver a legitimate, distinct psychotherapy service for a minimum of 16 minutes. This can include supportive therapy, psychoeducation, or discussing coping skills, but it must be a deliberate therapeutic intervention, not just a casual conversation. Ensure your training in psychotherapy is well-documented and that your clinical notes clearly reflect the therapeutic work performed to avoid any suggestion of fraudulent billing.
