CPT Code 90837: The Definitive Guide to Reimbursement Rates & Billing in 2026
If you're a therapist, LPC, LCSW, LMFT, or psychiatrist billing for 60-minute psychotherapy sessions, CPT code 90837 is likely your highest-revenue line item. It's also one of the most audited, most misunderstood, and most frequently underpaid codes in behavioral health billing.
This guide breaks down everything you need to know about 90837 in 2026 — from what it actually covers, to exact reimbursement rates by payer, to the documentation mistakes that are costing you money right now.
Let's get into it.
What Is CPT Code 90837?
CPT code 90837 is defined by the American Medical Association (AMA) as:
Psychotherapy, 60 minutes with patient
It's part of the psychotherapy family of codes maintained by the AMA and reported by licensed mental health clinicians — including Licensed Professional Counselors (LPCs), Licensed Clinical Social Workers (LCSWs), Licensed Marriage and Family Therapists (LMFTs), psychologists, and psychiatrists — when delivering individual therapy sessions.
The Critical Time Threshold
This is where most billing errors happen. 90837 requires a minimum of 53 minutes of face-to-face psychotherapy time. Not 45 minutes. Not 50. Fifty-three.
Here's the full breakdown of individual psychotherapy time-based codes so you know exactly which one to use:
| CPT Code | Session Length | Minimum Time Required |
|---|---|---|
| 90832 | 30 minutes | 16 minutes |
| 90834 | 45 minutes | 38 minutes |
| 90837 | 60 minutes | 53 minutes |
If your session runs 52 minutes of actual psychotherapy time, you must bill 90834, not 90837. Over-reporting time is a compliance risk that can trigger audits, recoupments, and in severe cases, fraud allegations. Document the actual time — always.
CPT Code 90837 Reimbursement Rates in 2026
Reimbursement rates for 90837 vary significantly by payer, geographic location (Medicare locality), and your provider's in-network status. Below are current 2026 benchmarks based on CMS data and payer fee schedules.
Medicare 2026 Reimbursement
The Centers for Medicare & Medicaid Services (CMS) sets the national baseline. For 2026, the Medicare non-facility rate for CPT 90837 is approximately:
- National average: $134–$148 per session
- Rates vary by Medicare Administrative Contractor (MAC) locality — practitioners in high-cost metro areas (New York City, San Francisco, Boston) typically receive higher locality-adjusted rates.
💡 Pro tip: Look up your exact Medicare rate using the CMS Physician Fee Schedule Look-Up Tool and filter by your state and locality code. The 2026 final rule was published in November 2025.
Medicaid Reimbursement for 90837
Medicaid rates are set at the state level and are notoriously inconsistent. Here's a general range by state tier:
| State Tier | Approximate 90837 Rate |
|---|---|
| High (CA, NY, WA, MA) | $110–$145 |
| Mid (TX, FL, IL, OH) | $75–$110 |
| Low (AL, MS, AR, WV) | $55–$80 |
If you're billing Medicaid, confirm rates directly with your state Medicaid agency or managed Medicaid plan (e.g., Molina Healthcare, Centene, Elevance/Anthem Medicaid).
Commercial Payer Reimbursement for 90837 (2026 Estimates)
Commercial rates are typically negotiated and confidential, but here are realistic ranges based on industry benchmarks and provider-reported data:
| Payer | Estimated 90837 Rate |
|---|---|
| Aetna | $130–$175 |
| Anthem/Elevance | $125–$170 |
| Cigna | $120–$165 |
| UnitedHealthcare (UHC) | $125–$175 |
| Blue Cross Blue Shield (varies by plan) | $115–$180 |
| Humana | $110–$150 |
| Magellan/Evernorth | $105–$140 |
| Tricare | $120–$155 |
| Oscar Health | $100–$140 |
| Optum | $125–$165 |
These rates fluctuate based on your geographic region, group vs. solo practice status, and negotiated contract terms. If you haven't renegotiated your rates with commercial payers in the last 2–3 years, you're almost certainly leaving money on the table.
Out-of-Pocket (Self-Pay) Rates for 90837
Self-pay rates for a 60-minute therapy session in 2026 range from $150 to $300+ depending on your market and specialty. Urban practitioners in high-demand specialties (trauma, DBT, EMDR) routinely charge $200–$275 per session. If you're billing insurance and also seeing self-pay clients, having a transparent sliding scale policy is both ethically sound and good business practice.
Who Can Bill CPT Code 90837?
Not every clinician can bill 90837 independently. Here's the breakdown:
Can bill 90837 independently (when credentialed with payer):
- Licensed Psychologists (PhD, PsyD)
- Licensed Clinical Social Workers (LCSW)
- Licensed Professional Counselors (LPC, LPCC)
- Licensed Marriage and Family Therapists (LMFT)
- Psychiatrists (MD, DO)
- Psychiatric Nurse Practitioners (PMHNP) — billing under their own NPI where allowed
May require supervision or incident-to billing:
- Provisionally licensed clinicians (LPC-Associate, LCSW-A, etc.)
- Pre-licensed therapists in group practices
⚠️ Important: "Incident-to" billing rules vary dramatically by payer. Medicare, for instance, does not allow incident-to billing for mental health services in the same way it does for medical services. Always verify credentialing requirements before billing under a supervisor's NPI.
90837 + Add-On Codes: What You Can Bill Together
One of the most underused billing opportunities for therapists involves pairing 90837 with appropriate add-on codes. Here are the most common:
90837 + 90785 (Interactive Complexity)
Add-on code 90785 can be appended to 90837 when sessions involve specific complicating factors such as:
- The patient requires the involvement of a third party (parent, guardian, translator)
- The patient has a high risk of danger to self or others during the session
- There are mandated reporting considerations
- Maladaptive communication patterns require additional clinical management
Reimbursement for 90785: Typically $15–$25 additional per session.
90837 for Psychiatrists: E/M + Psychotherapy Combination Codes
When a psychiatrist (or PMHNP) provides both a medical evaluation/management service AND psychotherapy in the same session, they use combination codes rather than 90837 alone:
- 90833 – Psychotherapy add-on, 30 min (with E/M)
- 90836 – Psychotherapy add-on, 45 min (with E/M)
- 90838 – Psychotherapy add-on, 60 min (with E/M)
These are paired with the appropriate E/M code (e.g., 99213, 99214). Non-physician therapists who are not providing E/M services should not use these combination codes.
Documentation Requirements for CPT 90837
Here's the uncomfortable truth: most claim denials and audit recoupments for 90837 aren't about billing errors — they're about documentation failures. The clinical note has to support the code you billed.
For 90837, your documentation must include:
1. Start and Stop Times (or Total Time)
Document the precise start and end time of the psychotherapy session, or clearly state the total face-to-face psychotherapy minutes. "60-minute session" is not enough — some payers require specific timestamps.
2. Patient's Presenting Problems and Chief Complaint
What did the patient bring to the session? What were they working through today?
3. Therapeutic Interventions Used
Name your modalities. Don't just write "supportive therapy." Write:
- "Utilized Cognitive Behavioral Therapy (CBT) techniques to identify and challenge cognitive distortions related to patient's social anxiety"
- "Applied trauma-focused interventions consistent with EMDR Phase 3–6"
- "Practiced DBT distress tolerance skills (TIPP technique)"
4. Patient's Response to Treatment
How did the patient engage? Was there progress, resistance, breakthrough, regression? The note should tell a clinical story.
5. Risk Assessment
Payers increasingly scrutinize whether a brief risk screening was conducted. Document suicidality, homicidality, and self-harm status — even if the response is "patient denies."
6. Plan and Next Steps
What's the treatment plan going forward? Next session date, homework assigned, referrals made, coordination of care.
7. Medical Necessity Language
This is the #1 thing missing from audited notes. The documentation must make clear why the patient requires 60 minutes of psychotherapy — not 30, not 45. Complexity of presentation, active crisis, multiple comorbidities, and treatment plan goals all support medical necessity for the longer session.
Common Reasons 90837 Claims Get Denied
If you're seeing 90837 denials pile up, here are the most likely culprits:
- Billing 90837 for a session under 53 minutes — Document your time meticulously
- Missing or inadequate diagnosis codes — Always pair with a valid ICD-10-CM code (e.g., F33.1 for Major Depressive Disorder, F41.1 for GAD)
- Using 90837 with E/M codes incorrectly — Non-physicians should not combine 90837 with E/M codes
- Credentialing mismatch — Billing under a provider who isn't credentialed with that payer
- Exceeding session limits without authorization — Many plans limit outpatient therapy sessions; verify authorizations before hitting session caps
- Missing modifier when required — Some payers require modifier GT (telehealth) or 95 for video sessions; others require modifier HO for mental health
- Duplicate billing — Billing 90837 and 90834 on the same date for the same patient
Telehealth Billing for CPT 90837 in 2026
Good news: telehealth parity has expanded, and the majority of commercial payers and Medicare continue to reimburse 90837 at the same rate for telehealth as in-person sessions in 2026.
Key telehealth billing tips for 90837:
- Use Place of Service (POS) 02 for telehealth sessions (or POS 10 for patient's home, depending on payer requirements)
- Append modifier 95 for synchronous telehealth for most payers
- Medicare requires audio-visual capability — audio-only sessions may need modifier 93 and are subject to additional rules
- Document the patient's location at the time of service (especially for out-of-state licensure compliance)
- Confirm the patient was physically located in a state where you hold licensure
90837 vs. 90834 vs. 90832: Which Code Should You Use?
This is one of the most common questions we hear from therapists. Here's the bottom line:
| Scenario | Correct Code |
|---|---|
| Session lasted 52 minutes | 90834 |
| Session lasted 55 minutes | 90837 |
| Session lasted 38 minutes | 90834 |
| Session lasted 30 minutes | 90832 |
| Session lasted 25 minutes | 90832 |
| Session lasted 16 minutes | 90832 |
| Session lasted under 16 minutes | No psychotherapy code — consider 90839 for crisis or document as a check-in |
Never round up. If your session ran 52 minutes, billing 90837 is upcoding — a federal compliance risk. Always document actual time and bill the code that matches.
How to Maximize Legitimate Reimbursement for 90837
You're entitled to every dollar you've earned. Here's how to protect it:
- Negotiate your contracts — Don't accept the first rate a payer offers. If you have high volume or a specialty in demand (e.g., trauma, eating disorders, adolescents), use that as leverage.
- Use 90785 when clinically appropriate — This add-on is underused and legitimate.
- Ensure clean claims on first submission — Rejected claims that require resubmission cost you time and often result in reduced payment timelines.
- Track your denial rate by code — If 90837 has a higher denial rate than your other codes, dig into the pattern.
- Invest in documentation quality — Audit-ready notes are your #1 protection against recoupment demands. Payers like UHC and Cigna have aggressively pursued behavioral health audits in recent years.
- Appeal denials consistently — The behavioral health industry has a shockingly low appeal rate. Most denials that are appealed with proper documentation are overturned.
FAQ: CPT Code 90837
Q1: Can I bill 90837 for a telehealth session?
Yes. Most commercial payers and Medicare reimburse 90837 for synchronous telehealth (audio-video) at the same rate as in-person. Use the appropriate telehealth modifier (95 for most commercial payers, or 93 for audio-only Medicare sessions). Always verify payer-specific rules, as they vary.
Q2: How often can I bill 90837 per patient?
There's no universal limit on session frequency, but payers may impose session limits per benefit year (commonly 20–52 sessions). Sessions beyond that limit typically require prior authorization and documented medical necessity. Some plans require authorization from session one.
Q3: Can a provisionally licensed therapist bill 90837?
It depends on the payer and your state's licensure laws. Some payers credential pre-licensed clinicians under a supervisor's NPI using incident-to rules. Others require independent licensure. Medicare does not allow incident-to billing for mental health services. Always verify with your payer before billing.
Q4: What ICD-10 codes pair best with 90837?
Any valid DSM-5 aligned ICD-10 diagnosis supports 90837. Common pairings include:
- F33.1 – Major Depressive Disorder, recurrent, moderate
- F41.1 – Generalized Anxiety Disorder
- F43.10 – Post-Traumatic Stress Disorder, unspecified
- F31.81 – Bipolar II Disorder
- F60.3 – Borderline Personality Disorder
- F90.0 – ADHD, predominantly inattentive type
Avoid using Z-codes (e.g., Z63.0, relationship distress) as the primary diagnosis for 90837, as some payers consider these insufficient to establish medical necessity for intensive psychotherapy.
Q5: What's the difference between 90837 and 90847?
90837 is individual psychotherapy (one patient, no family present in a therapeutic role). 90847 is family psychotherapy with the patient present. If you're seeing a couple or family unit and the identified patient is participating, 90847 is the correct code. Use 90846 for family therapy when the patient is not present.
Q6: Do I need a treatment plan on file to bill 90837?
Yes — virtually every payer requires an active treatment plan to support ongoing psychotherapy billing. The treatment plan should include measurable goals, estimated duration of treatment, frequency of sessions, and the therapeutic modalities being used. Failure to maintain an updated treatment plan is one of the top reasons behavioral health claims are recouped in audits.
Q7: How do I handle 90837 if my session goes over 60 minutes?
If your session consistently runs 75–90 minutes, you may want to review whether there's a more appropriate billing structure. For individual sessions exceeding 60 minutes, there is no higher timed psychotherapy code for non-crisis situations — 90837 is the ceiling for standard individual therapy. Some practices bill at the 90837 rate regardless of whether the session ran 55 or 80 minutes, which is a billing decision (not a compliance violation as long as the minimum 53-minute threshold is met). For crisis situations, consider 90839/90840.
Final Thoughts: Documentation Is Your Revenue Cycle
Billing 90837 accurately and confidently comes down to one thing: documentation that tells the clinical story and supports the code. The reimbursement is there. The billing rules are learnable. The piece most practices get wrong — and the piece that costs them the most — is the clinical note.
Whether you're a solo therapist seeing 20 clients a week or a group practice with 30 providers, the quality and consistency of your progress notes determine your revenue cycle stability, your audit exposure, and frankly, your peace of mind.
