Clinicians navigating mental health billing know that accuracy in coding is essential to effective reimbursement. One frequently used psychotherapy billing code is CPT code 90834. This article will break down everything you need to understand about CPT 90834, from its definition and clinical applications to billing guidelines and tips for optimal use.
What Is CPT Code 90834?
CPT (Current Procedural Terminology) code 90834 describes an individual, face-to-face psychotherapy session lasting approximately 45 minutes (between 38 and 52 minutes). This includes face-to-face interactions with the patient and/or family members, typically used in outpatient settings.
CPT 90834 specifically covers psychotherapy without additional evaluation and management (E/M) services. If psychotherapy and evaluation and management occur together, clinicians must use different codes, such as 90836.
Clinical Use of CPT 90834
CPT 90834 is widely applicable across various clinical scenarios, including treatment for:
- Depression
- Anxiety disorders
- Post-traumatic stress disorder (PTSD)
- Adjustment disorders
- Relationship or family difficulties
Clinicians typically use 90834 when sessions involve moderate complexity and require around 45 minutes of direct patient interaction. Sessions under this code often include cognitive-behavioral therapy (CBT), interpersonal psychotherapy (IPT), dialectical behavior therapy (DBT), and supportive psychotherapy.
Comparing CPT Codes 90834 and 90836
While CPT 90834 covers 45-minute psychotherapy sessions without additional medical services, CPT 90836 is specifically designated for 45-minute psychotherapy sessions combined with an evaluation and management (E/M) service. This means that clinicians using CPT 90836 are providing psychotherapy along with medical evaluation or management during the same encounter.
The key differences include:
- 90834: Psychotherapy only (approx. 45 minutes).
- 90836: Psychotherapy (approx. 45 minutes) plus E/M services.
Clinicians should use 90836 when medically necessary services such as prescribing medication, adjusting treatments, or performing medical evaluations occur alongside psychotherapy within the same session. 90836 is an add-on code that can only be billed with an appropriate E/M code.
Coding Guidelines and Duration Requirements
The AMA guidelines for CPT 90834 stipulate a session duration of approximately 45 minutes (range: 38-52 minutes). Clinicians should document precise session start and end times to ensure accuracy. Time documentation is critical to justify the appropriateness of this code and defend against insurance audits.
If sessions significantly deviate from this time frame, other codes should be used:
- 90832: Psychotherapy, 30 minutes (16-37 minutes)
- 90837: Psychotherapy, 60 minutes (53 minutes or longer)
Using CPT 90834 appropriately ensures accurate billing and avoids claim denials.
Documentation Requirements
Detailed documentation supports clinical justification and billing accuracy. Notes must clearly document:
- Date and exact times of session
- Therapeutic interventions provided
- Patient's response and progress
- Treatment plan adjustments if needed
- Rationale for session length and approach
Clinicians should ensure each note demonstrates medical necessity for 45-minute sessions.
Note, for CPT 90836, documentation must also clearly reflect the medical evaluation and management component, specifying the medical issues addressed and actions taken.
Reimbursement and Insurance Coverage
Reimbursement for CPT 90834 varies by insurance provider, geographical location, and specific contracts. On average, reimbursement rates range from $75 to $175 per session. Providers should verify coverage specifics and prior authorization requirements with payers.
Medicare and Medicaid typically cover CPT 90834, though reimbursement rates can differ substantially from private insurance. Clinicians must remain vigilant about staying current with insurance-specific coding and billing guidelines.
Common Mistakes and How to Avoid Them
Clinicians frequently encounter claim denials or audits due to common coding errors. These pitfalls include:
- Inaccurate Session Timing: Ensure your session durations match CPT 90834 criteria.
- Insufficient Documentation: Include clear, detailed therapy notes justifying the session.
- Billing for Evaluation and Management Separately: Do not bill 90834 alongside an E/M code unless applicable (use 90836 for combined services).
By avoiding these common errors, clinicians can minimize denials and streamline their billing processes.
Differences from Similar CPT Codes
Understanding the distinctions between similar psychotherapy codes helps in proper billing:
- 90832: Shorter psychotherapy session (30 minutes)
- 90837: Longer psychotherapy session (60 minutes)
- 90847: Family psychotherapy, conjoint, with the patient present
- 90846: Family psychotherapy without patient present
Knowing when to apply each code appropriately ensures accurate reimbursement and fewer administrative headaches.

Conclusion
CPT 90834 is essential for billing psychotherapy sessions lasting approximately 45 minutes.

Frequently Asked Questions About CPT 90834
Q: Can I bill CPT 90834 more than once per day per patient?
A: Generally, no. CPT 90834 covers a single psychotherapy session per patient per day. Billing multiple sessions in a day typically requires special justification.
Q: Can CPT 90834 be used for telehealth sessions?
A: Yes. CPT 90834 is widely accepted for telehealth services, especially since telemedicine became common during the COVID-19 pandemic. Always verify with individual payers.
Q: What if my session goes slightly over or under the recommended time frame?
A: If sessions vary consistently, consider using another code (90832 or 90837). Occasional minor variations within a few minutes typically do not necessitate code changes.
