CPT code 90834 covers individual psychotherapy sessions running 38 to 52 minutes of face-to-face time — commonly called the “45-minute therapy session.” It’s the highest-volume psychotherapy code in most outpatient behavioral health practices, which means small errors in how it’s billed compound fast across a caseload.
This guide covers the exact time range, 2026 Medicare and credential-based reimbursement rates, how to avoid downcoding and denial risk, the add-on codes for combined E/M and therapy visits, telehealth rules, and the documentation that actually protects the claim.
Quick Answer
| Code | 90834 |
| Service | Individual psychotherapy |
| Time range | 38–52 minutes, face-to-face |
| 2026 Medicare rate (non-facility) | ~$113.90 |
| Billed alone or with E/M? | Alone — use add-on codes (+90833/+90836/+90838) when combined with an E/M visit |
| Telehealth eligible? | Yes, with modifier 95 and correct place-of-service code |
What CPT Code 90834 Covers
CMS classifies the service under 90834 as insight-oriented, behavior-modifying, supportive, and/or interactive psychotherapy — a description that applies regardless of which specific therapeutic modality the clinician uses. In practice, this covers one-on-one sessions using evidence-based approaches such as cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), interpersonal therapy (IPT), EMDR, psychodynamic therapy, or solution-focused interventions.
Don’t bill 90834 for:
- Psychiatric diagnostic evaluations (90791/90792)
- Group therapy (90853)
- Family therapy, with or without the patient present (90847/90846)
- Crisis psychotherapy (90839/90840)
90834 vs. 90832 vs. 90837: Choosing the Right Code
Code selection comes down entirely to documented face-to-face time — not the type of therapy performed.
| Code | Time Range | Typical Use |
|---|---|---|
| 90832 | 16–37 minutes | Brief check-ins, med-management-adjacent sessions, some telehealth-driven shorter visits |
| 90834 | 38–52 minutes | Standard session length; the highest-volume code in most practices |
| 90837 | 53 minutes or longer | Extended sessions for complex cases or intensive modalities |
A session that runs to 50 minutes is still billed as 90834 — it only becomes 90837 once documented time reaches 53 minutes or more. There’s no code for sessions beyond 60 minutes on their own; extended time beyond that is captured with the prolonged services add-on code (99354), where applicable.
The Downcoding Risk You Need to Watch
This is one of the most common sources of revenue leakage in psychotherapy billing, and it runs in both directions:
- 90837 sessions get downcoded to 90834 when documentation doesn’t clearly establish that the session reached the 53-minute threshold. Payers treat missing or vague time documentation as grounds for downcoding — or for denial and post-payment audit if the pattern repeats.
- Billing 90834 when a session only reached 30–35 minutes is the inverse problem: it’s a real audit trigger if your documented time consistently falls short of 38 minutes.
The fix is the same either way: document actual clock times (start and end), not just a session duration estimate written from memory after the fact.
2026 Reimbursement Rates
| Payer / Scenario | 2026 Rate (approx.) |
|---|---|
| Medicare, non-facility, psychologist/psychiatrist | $113.90 |
| Medicare, non-facility, LMFT/LMHC (75% of standard rate) | ~$85.43 |
| Medicare, facility setting | Lower than non-facility — verify your specific facility differential via the CMS fee schedule tool |
| Commercial payers | Vary by contract; often benchmarked against the Medicare non-facility rate |
The 2026 increase reflects a Medicare conversion factor rise to approximately $33.40 for non-Qualifying Participant (non-QPP) providers and $33.57 for QPP participants, up from $32.35 in 2025 — roughly a 3.3–3.8% increase year over year.
LMFTs and LMHCs can now enroll in Medicare directly and bill psychotherapy codes, including 90834, at 75% of the standard psychologist/psychiatrist rate. This is a relatively recent expansion worth confirming applies to your enrollment status before billing.
Facility vs. non-facility matters more than many practices realize — the differential can meaningfully affect per-session revenue for treatment centers billing under facility arrangements, since non-facility rates account for the overhead a private practice absorbs that a facility-based provider doesn’t.

Billing 90834 with an E/M Visit: Add-On Codes
When a psychiatrist or psychiatric nurse practitioner provides both medication management and psychotherapy in the same visit, the services are billed together as an E/M code (99211–99215) plus a psychotherapy add-on code. These add-on codes mirror the standalone time bands but cannot be billed alone:
| Add-On Code | Mirrors | Use With |
|---|---|---|
| +90833 | 90832 time range (16–37 min) | E/M code, same visit |
| +90836 | 90834 time range (38–52 min) | E/M code, same visit |
| +90838 | 90837 time range (53+ min) | E/M code, same visit |
If no E/M service is provided — pure psychotherapy with no medication management or medical evaluation component — bill the standalone code (90832, 90834, or 90837) instead of the add-on version.
Telehealth Billing for 90834
90834 is eligible for telehealth delivery when payer requirements and documentation standards are met. Two things are required on the claim:
- Modifier 95 — appended to the code (90834-95) to indicate the session was delivered via real-time, face-to-face video. Text-based communication doesn’t qualify.
- Correct place-of-service code:
- POS 02 — patient received the service somewhere other than their home, using telehealth
- POS 10 — patient received the service at home, using telehealth
Confirm the patient has signed a telehealth consent form before billing telehealth sessions, and document both provider and patient locations along with the technology platform used.
Documentation That Protects the Claim
Because 90834 selection depends entirely on time, documentation needs to do more than describe the clinical content of the session:
- Actual start and end clock times — not just “45-minute session” written after the fact
- Medical necessity statement — why the patient needs psychotherapy at this frequency and duration
- Modality and clinical content — what specific approach was used and what was addressed
- For telehealth: patient consent on file, technology platform, and both parties’ locations
Weak note (audit risk)
“45-minute individual session. Discussed coping strategies. Patient tolerated session well.”
Stronger note (defensible)
“Session conducted 2:05–2:47 PM (42 minutes face-to-face). Continued CBT for generalized anxiety disorder per treatment plan goal #1. Reviewed thought-record homework, introduced cognitive restructuring technique for catastrophic thinking pattern. Patient engaged well; will continue weekly sessions given persistent functional impairment at work.”
The second version documents actual clock time, ties the session to a treatment plan goal, and states clinical reasoning — exactly what supports the code and the frequency being billed.
ICD-10 Pairing
90834 must be paired with a diagnosis code that supports the medical necessity of ongoing individual psychotherapy — common examples include codes from the F32 (major depressive disorder), F41 (anxiety disorders), and F43 (trauma- and stressor-related disorders) ranges, among others specific to the patient’s presentation. The severity and specificity of the diagnosis should reasonably match the intensity and frequency of treatment billed — a mismatch between a mild diagnosis and high-frequency, extended sessions is a documented audit flag.
Common Denial Reasons and Fixes
| Denial Reason | Fix |
|---|---|
| Session time not documented with actual clock times | Record start/end times, not just a stated duration |
| 90834 billed for a session under 38 minutes | Use 90832 instead, or extend and re-document if clinically appropriate |
| 90837 billed but documentation only supports ~45 minutes | Downcode to 90834 proactively, or ensure documentation clearly supports 53+ minutes |
| Billed with an E/M code using the standalone code instead of the add-on | Use +90836 (not 90834) when psychotherapy is combined with an E/M visit in the same session |
| Missing telehealth modifier or wrong POS code | Confirm modifier 95 and POS 02/10 are both present and correctly matched to the session location |
| Diagnosis severity doesn’t support treatment frequency/duration billed | Ensure ICD-10 code and treatment plan justify the frequency and length of sessions billed |
