Behavioral health billing is notoriously strict, especially when it comes to time-based codes. In 2026, payers are scrutinizing session times, tightening prior authorization rules, and actively auditing upcoded claims. Whether you are a solo practitioner or managing a large behavioral health clinic, understanding the exact rules behind these codes is the difference between getting paid your full rate and facing costly clawbacks.

This guide breaks down everything you need to know about psychotherapy billing in 2026, including exact time thresholds, Medicare rate estimates, and the latest Texas Medicaid (TMHP) rules.

What Are Psychotherapy CPT Codes?

Psychotherapy CPT codes (90832–90863) are billing codes used by behavioral health professionals to report talk therapy services. Unlike Evaluation and Management (E/M) codes that focus on medical decision-making or Psychiatric Evaluation codes used for initial assessments, psychotherapy codes are strictly time-based and describe targeted therapeutic interventions.

90834	Psychotherapy, 45 minutes	38–52 min	Individual	No
90837	Psychotherapy, 60 minutes	53+ min	Individual	No
90833	Psychotherapy, 30 minutes with E/M	16–37 min	Individual	Yes
90836	Psychotherapy, 45 minutes with E/M	38–52 min	Individual	Yes
90838	Psychotherapy, 60 minutes with E/M	53+ min	Individual	Yes
90846	Family psychotherapy (w/o patient)	50 min	Family	No
90847	Family psychotherapy (with patient)	50 min	Family	No
90853	Group psychotherapy	N/A	Group	No

Individual Psychotherapy Codes: 90832, 90834 and 90837

Standard individual psychotherapy is governed by three primary codes, separated entirely by the duration of face-to-face time with the patient.

• CPT 90832 (30 Minutes): Billed when the session lasts between 16 and 37 minutes. If your session is under 16 minutes, you cannot bill a psychotherapy code.
• CPT 90834 (45 Minutes): The most frequently billed code in behavioral health. This applies when face-to-face time falls between 38 and 52 minutes.
• CPT 90837 (60 Minutes): Used for extended sessions lasting 53 minutes or more.

Remember, the “midpoint rule” applies here. A session that lasts exactly 52 minutes is coded as 90834. Once the clock hits 53 minutes, it becomes 90837. There is no gray area.

90834 vs 90837: Which Code Should You Bill?

Deciding between 90834 and 90837 is the most common point of confusion and the biggest audit trigger for mental health providers.

Feature	CPT 90834	CPT 90837
Time Threshold	38 to 52 minutes	53+ minutes
Payer Preference	Highly preferred; rarely questioned.	Scrutinized; often requires medical necessity proof.
Audit Risk	Low	High (Upcoding red flag)
Common Denial Reason	Billed multiple times a week without authorization.	“Routine” billing of 60-minute sessions for all patients.

The Upcoding Trap: Auditors actively hunt for providers who bill 90837 exclusively. Because 90837 pays roughly 30% to 40% more than 90834, billing 50-minute sessions as 90837 is considered fraudulent upcoding. Your clinical notes must explicitly justify why a full 60-minute session was medically necessary.

Psychotherapy Add-On Codes With E/M: 90833, 90836 and 90838

When a prescribing provider (like a psychiatrist or PMHNP) provides both medication management (E/M) and talk therapy in the same visit, you must use add-on codes.

• 90833: 30 minutes of therapy combined with an E/M visit.
• 90836: 45 minutes of therapy combined with an E/M visit.
• 90838: 60 minutes of therapy combined with an E/M visit.

Crucial Billing Rules:

1. Add-on codes cannot be billed alone. They must accompany an E/M base code (e.g., 99213 or 99214).
2. You must append Modifier 25 to the E/M code to indicate a separate, distinct service was provided.
3. The time spent on the E/M service (reviewing meds, checking vitals) cannot be counted toward the psychotherapy time. The therapy time must be clearly separated in the documentation.

Psychiatric Diagnostic Evaluation Codes: 90791 and 90792

Before ongoing therapy begins, patients require an initial assessment.

• CPT 90791: Psychiatric diagnostic evaluation without medical services. Used primarily by psychologists, LCSWs, LPCs, and LMFTs.
• CPT 90792: Psychiatric diagnostic evaluation with medical services. Billed by MDs, DOs, and NPs who perform medical assessments and prescribe medications during the intake.

Note: These codes are typically only allowed once per patient per year unless there is a significant break in treatment or a major change in the patient’s condition.

Family, Couples and Group Psychotherapy Codes: 90846, 90847, 90849 and 90853

When treating more than just a single patient in the room, shift away from the standard 9083X series.

• CPT 90846: Family psychotherapy without the patient present (e.g., counseling parents on how to handle a child’s behavioral issues).
• CPT 90847: Family or couples psychotherapy with the patient present.
• CPT 90849: Multiple-family group psychotherapy.
• CPT 90853: Group psychotherapy (used for standard group therapy sessions, unrelated participants).

For group therapy (90853), the provider bills this code for each patient in the group. Ensure your documentation highlights how the group setting benefits the individual patient’s specific treatment plan.

Crisis Psychotherapy and Interactive Complexity Codes: 90839, 90840 and 90785

Crisis Codes

When a patient presents in a life-threatening or highly complex psychological crisis requiring immediate intervention:

• 90839: First 60 minutes of crisis psychotherapy.
• 90840: Each additional 30 minutes of crisis psychotherapy.

Interactive Complexity (90785)

CPT 90785 is an add-on code used when communication is severely impaired. Examples include treating a child using play therapy equipment, dealing with a highly combative patient, or needing a translator. It can be paired with primary psychotherapy codes but cannot be billed alongside E/M services alone.

How to Bill Extended Psychotherapy Sessions Over 60 Minutes

What happens when a severe trauma session pushes well past 60 minutes? The AMA removed prolonged service codes for standard psychotherapy, creating confusion.

Currently, if a standard individual session exceeds the 90837 threshold (53+ minutes), you generally only bill 90837. However, if the prolonged session transitions into a genuine crisis, you would discard 90837 entirely and switch to billing the crisis codes (90839 and 90840) based on the total time spent resolving the emergency.

Telehealth Billing for Psychotherapy: Modifiers 95, 93 and Place of Service

Telehealth remains a massive part of behavioral health in 2026, but the billing modifiers have shifted.

Place of Service (POS) Codes

• POS 10 (Telehealth Provided in Patient’s Home): Billed when the patient is logging in from their residence. Crucially, Medicare reimburses POS 10 at the non-facility rate, which is typically higher and matches in-office pay.
• POS 02 (Telehealth Provided Other than in Patient’s Home): Billed if the patient is in a hospital, clinic, or other off-site location. This often triggers lower facility payment rates.
• POS 11 (Office): Only use this if the patient is physically in your brick-and-mortar office. Billing a video session with POS 11 is an immediate red flag for an audit.

Modifiers

• Modifier 95: Synchronous audiovisual telehealth (Zoom, SimplePractice video).
• Modifier 93: Audio-only telehealth (phone call). Used when video is technically unavailable or the patient refuses video.
• Modifier GT: A legacy modifier. While mostly retired by Medicare, some strict commercial payers still require it.

Who Can Bill Psychotherapy CPT Codes?

Your credential dramatically impacts your reimbursement rates. While all licensed mental health professionals can bill standard psychotherapy codes, payers reimburse at tiered levels:

• Psychiatrists (MD/DO): Can bill all codes, including E/M combinations. Usually reimbursed at 100% to 110% of the standard rate.
• Psychologists (PhD/PsyD): Generally serve as the benchmark (100%) for psychotherapy reimbursement.
• NPs / PMHNPs: Typically reimbursed at 85% to 100% of the physician/psychologist rate.
• LCSWs, LPCs, LMFTs: Generally restricted from billing E/M codes (unless dual-credentialed). Medicare federal mandates reimburse master’s-level clinicians at 75% of the psychologist rate. Commercial insurers often follow a similar 75% to 90% sliding scale.

Psychotherapy CPT Code Documentation Requirements

“If it isn’t documented, it didn’t happen.” To bulletproof your behavioral health claims, every session note must include:

1. Exact Start and Stop Times: Never write “45 minutes.” Write “Session started at 10:00 AM; Session ended at 10:46 AM.”
2. Medical Necessity: Why did this patient need therapy today?
3. Treatment Modality: Note the evidence-based approach used (e.g., CBT, EMDR, DBT).
4. Patient Progress: How is the patient tracking toward their treatment plan goals?
5. ICD-10 Linkage: The diagnosis must support the frequency and length of the therapy billed.

Psychotherapy Reimbursement Rates in 2026

Reimbursement varies wildly based on your Geographic Practice Cost Index (GPCI), credential, and negotiated contracts. Note: The following are approximate 2026 estimates based on non-facility national averages.

• 90791 (Evaluation): ~$166.91 to $173.45
• 90832 (30 min): ~$78.93 to $85.89
• 90834 (45 min): ~$104.16 to $113.97
• 90837 (60 min): ~$154.29 to $167.10

Commercial insurance rates generally float between $100 and $175 for a 45-minute session, while state Medicaid rates tend to average between $60 and $80 depending on location. If your commercial contracts are paying below the Medicare threshold, it is time to renegotiate.

Texas Medicaid and Texas Payer Rules for Psychotherapy Billing

For practitioners in the Lone Star State, TMHP (Texas Medicaid & Healthcare Partnership) introduces specific compliance layers that out-of-state billers routinely miss.

The New 2026 Prior Authorization Rules: Effective January 1, 2026, Texas Medicaid implemented a strict new timeline for prior authorizations (PAs).

• Standard PA Requests: MCOs must make a decision within 7 calendar days.
  The Medicator’s
• Urgent PA Requests: If a delay risks severe health decline, decisions must be rendered within 72 hours.

Texas Billing Strategy: To survive these tight windows, your documentation must be pristine upon first submission. Extended psychotherapy sessions (like 90837) almost always trigger a PA requirement under Texas Medicaid. You must prove clinical necessity, for instance, noting that a patient with severe generalized anxiety requires 60-minute sessions to prevent symptom decompensation. Using clean data, the right Texas Medicaid portal, and tagging urgent requests appropriately will save your revenue cycle from grinding to a halt.

Common Psychotherapy Billing Errors and Claim Denials

Avoid these rapid-fire ways to get your claims kicked back:

• The “Time Bracket” Miss: Billing 90834 for a 36-minute session (which should be 90832).
• Routine 90837 Billing: Flagging every patient for a 60-minute session guarantees an eventual audit.
• Missing E/M Modifiers: Forgetting Modifier 25 when a psychiatrist bills 99213 + 90836.
• Invalid Place of Service: Putting POS 11 on a telehealth claim instead of POS 10.
• Unspecified ICD-10 Codes: Using general “unspecified depression” codes rather than specific, highly detailed diagnoses that justify ongoing care.

Frequently Asked Questions

Can I bill 90834 and 90837 on the same day? 

No. You can only bill one primary individual psychotherapy code per day per patient.

Does standard therapy time include charting? 

No. Psychotherapy CPT codes strictly measure face-to-face time with the patient. Time spent reviewing the chart beforehand or writing notes afterward does not count toward the 16, 38, or 53-minute thresholds.

Can an LPC or LCSW bill an E/M add-on code? 

Generally, no. Evaluation and Management (E/M) codes are reserved for medical providers (MD, DO, NP, PA) who are actively managing medications and medical decision-making.

What happens if a session is less than 16 minutes? 

You cannot bill a psychotherapy CPT code. If a provider is managing medications during that brief window, an appropriate E/M code might be applicable, but standard therapy codes begin strictly at the 16-minute mark.

Who can bill psychotherapy CPT codes?

Psychotherapy codes aren’t limited by job title, so licensed professionals such as psychologists, LCSWs, LPCs, LMFTs and psychiatrists can all use them.
