CPT Codes for Psychiatric Services: Billing Guide

Psychiatric billing can go wrong even when the clinical care is appropriate. A follow-up may include medication management, psychotherapy, crisis intervention, or family involvement, and each service has different coding rules. 

For psychiatrists, psychiatric nurse practitioners, practice managers, and billers, choosing the right CPT codes for psychiatric services can affect whether claims are paid cleanly, delayed, or denied.

The problem lies in the selection of a code that represents the same service. Practices should also have accurate time documentation, separate psychotherapy from E/M work, and comply with the telehealth guidelines of paying agencies. 

The American Psychiatric Association (APA) recommends using the most recent AMA CPT manual for verification, and not old code sheets.

This guide focuses on common outpatient psychiatric coding scenarios. Provider eligibility, coverage, and billing rules can vary by payer, credential, state, and service.

What Are CPT Codes for Psychiatric Services?

CPT codes for psychiatric services are procedure codes used to describe the professional services delivered during psychiatric care.

They may represent services such as:

• Psychiatric diagnostic evaluations
• Medication management through E/M services
• Individual psychotherapy
• Psychotherapy performed with E/M
• Family psychotherapy
• Group psychotherapy
• Crisis psychotherapy
• Interactive complexity

Psychiatric practices use CPT coding alongside other coding systems.

In simple terms:

• CPT codes describe what service was performed
• ICD-10-CM codes describe the diagnosis or condition
• HCPCS Level II codes may apply to certain Medicare or payer-specific services

The diagnosis alone does not determine the CPT code.

For example, two patients with the same psychiatric diagnosis may receive completely different services. One may receive a medication-management visit, while another receives 45 minutes of psychotherapy.

The documentation must support the billed service. Coverage, authorization, and payment rules can still vary by payer.

Start with the service actually performed and documented. Then determine the appropriate CPT code and verify payer requirements.

Common CPT Codes for Psychiatric Services

The most frequently used outpatient psychiatric CPT codes generally fall into six categories:

• Diagnostic evaluation
• Evaluation and management
• Individual psychotherapy
• Family and group psychotherapy
• Crisis services
• Psychiatric add-on services

CPT Code	Common Use	Key Coding Consideration
90791	Psychiatric diagnostic evaluation without medical services	Used when medical services are not part of the evaluation
90792	Psychiatric diagnostic evaluation with medical services	Psychiatric diagnostic evaluation that includes medical services
90832	Individual psychotherapy	16–37 minutes
90834	Individual psychotherapy	38–52 minutes
90837	Individual psychotherapy	53 minutes or more
+90833	Psychotherapy with E/M	16–37 minutes of psychotherapy
+90836	Psychotherapy with E/M	38–52 minutes of psychotherapy
+90838	Psychotherapy with E/M	53 minutes or more of psychotherapy
90846	Family psychotherapy	Patient not present
90847	Family psychotherapy	Patient present
90853	Group psychotherapy	Used for eligible group psychotherapy services
90839	Psychotherapy for crisis	First 60 minutes
+90840	Additional crisis psychotherapy	Additional 30-minute increments
+90785	Interactive complexity	Add-on code for qualifying communication complexity
99202–99205	New-patient office/outpatient E/M	Level based on applicable E/M rules
99212–99215	Established-patient office/outpatient E/M	May apply to established-patient psychiatric E/M visits based on the level of service

CMS separates psychotherapy add-on codes, which are provided when psychotherapy is delivered with an E/M service, from standalone psychotherapy codes (90832, 90834 and 90837).

Psychiatric Diagnostic Evaluation: 90791 vs. 90792

A separate E/M code also should not be reported by the same practitioner with 90791 or 90792 for that encounter.

90791 generally describes a psychiatric diagnostic evaluation without medical services.

The evaluation may include:

• History gathering
• Mental status examination
• Psychiatric assessment
• Diagnostic formulation
• Treatment recommendations

90792 describes a psychiatric diagnostic evaluation that includes medical services when performed by an appropriately qualified provider.

That may include clinically appropriate elements such as:

• Medical assessment
• Medication-related evaluation
• Relevant physical examination elements
• Prescription considerations
• Medical decision-making

These codes should not simply be treated as generic “new patient” codes. The code should reflect what occurred during the encounter.

For Medicare, psychiatric diagnostic evaluation codes generally should not be reported with psychotherapy for the same patient on the same date. E/M codes also should not be reported with 90791 or 90792 for the same diagnostic service.

A repeat evaluation may be appropriate after a major clinical change or break in treatment. Practices should verify payer-specific frequency and coverage policies.

Individual Psychotherapy Codes

The three common standalone individual psychotherapy codes are:

• 90832: 16–37 minutes
• 90834: 38–52 minutes
• 90837: 53 minutes or more

The total appointment length is not necessarily the psychotherapy time.

Document psychotherapy time clearly. When psychotherapy is reported with E/M, do not include E/M time in the psychotherapy duration.

For example, if part of the encounter involves administrative activity or separately billable E/M work, that time should not automatically be counted toward the psychotherapy code.

Family and Group Psychotherapy

Psychiatric and behavioral health practices may also use:

• 90846: Family psychotherapy without the patient present
• 90847: Family psychotherapy with the patient present
• 90853: Group psychotherapy

Family psychotherapy codes are intended for treatment of the patient’s mental health condition. They should not be used simply for taking a family history or providing routine E/M counseling.

Documentation should establish:

• Why the service was clinically appropriate
• Who participated
• What therapeutic work occurred
• How the service relates to the patient’s treatment

A CPT code list may be used for reference but the final selection depends on the service provided, time spent, type of provider, documentation and requirements of the payer.

How to Bill Psychiatric E/M and Psychotherapy Together

A psychiatrist may provide E/M and psychotherapy during the same visit. If both services are significant and separately identifiable, the claim may include an E/M code and a psychotherapy add-on code.

Common new-patient E/M codes include 99202–99205. Common established patient codes used in mental health care include 99212–99215.

For many office E/M visits, the level can be based on medical decision-making or total time. The rule changes when E/M is billed with psychotherapy.

The APA states that when psychiatrists report E/M with psychotherapy, the E/M level must be based on medical decision-making, not time. CMS also states that E/M time cannot count toward psychotherapy time.

For example, a medication assessment plus 25 minutes of separate psychotherapy may support an E/M code with 90833. The note should support both the medical decision-making and the psychotherapy time.

Do not use 90832, 90834, or 90837 as the therapy part of an E/M-plus-therapy visit by the same billing clinician. Those are standalone therapy codes.

Use the psychotherapy add-on family when the rules are met:

• 90833: 16–37 minutes
• 90836: 38–52 minutes
• 90838: 53 minutes or more

For psychiatrists and other qualified healthcare professionals who can report E/M services, medication management is generally reported through the applicable E/M framework rather than 90863.

When medication management and psychotherapy happen in the same visit, keep each part clear in both the note and the claim.

CPT Codes for Psychiatric Services Delivered Through Telehealth

Telepsychiatry may use the same core CPT code. The claim can still require additional information.

Practices may need to confirm:

• Whether the CPT service is eligible for telehealth
• Whether video or audio-only delivery is covered
• Where the patient was located
• Where the clinician was located
• Which place-of-service code applies
• Whether a telehealth modifier is required
• Whether prior authorization applies
• Whether the payer has additional documentation rules

Medicare Telehealth Place of Service

CMS defines two important telehealth place-of-service codes.

POS 10 – Telehealth Provided in Patient’s Home

Used when the patient receives the telehealth service while located in their home.

POS 02 – Telehealth Provided Other Than in Patient’s Home

Used when the patient receives telehealth somewhere other than their home.

Check Medicare telehealth eligibility for the specific service and date of service. These rules can change.

Mental health telehealth may also have federal rules and exceptions that differ from other Medicare services.

Requirements may vary with commercial plans, Medicare Advantage and state Medicaid plans. What is successful for one payer can not be successful for every other.

A practical payer matrix can track:

• Covered psychiatric services
• Video requirements
• Audio-only policies
• POS requirements
• Required modifiers
• Authorization rules
• Provider eligibility
• Patient-location restrictions

Use a payer-specific workflow for telehealth billing. Make sure you have confirmed the CPT code, the modality, patient location, POS, modifier and coverage policy before claiming.

Documentation and Billing Errors That Cause Psychiatric Claim Problems

Most coding problems occur when the note and claim tell different stories.

1. Psychotherapy Time Does Not Support the Code

A 45-minute appointment does not always support 90834. Part of that visit may have been used for E/M.

When both services are billed, psychotherapy time should be separate from E/M time. The note should make that distinction clear.

2. E/M and Psychotherapy Are Not Separately Identifiable

A blended note may mix symptoms, a med review, counseling, and a care plan. That can make it hard to show two separate services.

Keep the medical work and psychotherapy work clear. Do this without adding duplicate or unnecessary documentation.

3. Interactive Complexity Is Treated as a Routine Add-On

Code 90785 is not a generic code for a “difficult patient.”

It applies when specific communication factors make the psychiatric service more complex. Examples may include hard communication among people in the visit or specific communication or third-party factors that complicate the delivery of the psychiatric service.

It is an add-on code. It is not reported with crisis psychotherapy.

4. Crisis Codes Are Combined With Incompatible Psychiatric Codes

CMS says not to bill 90839 or 90840 with certain diagnostic evaluation or standard therapy codes for the same crisis service. This is a coding and bundling issue. It is not only a documentation preference.

5. The Practice Assumes Every Payer Follows Medicare

Medicare, Medicaid, Medicare Advantage, and commercial plans can apply different billing rules.

A CPT code may be valid but still not be covered by a plan. A payer may also require authorization, a modifier, or a frequency limit.

Ensure that before the claim exits the practice, the code, time, diagnosis, documentation, provider, payer and place of service are in alignment.

Psychiatric Billing Problem vs. Recommended Control

Billing Problem	Recommended Control
Wrong psychotherapy code	Capture actual psychotherapy time
E/M and therapy documentation overlap	Separate medical and psychotherapy work
Telehealth claim rejection	Validate POS, modifier, modality, and payer policy
Incorrect diagnostic evaluation code	Confirm whether medical services were provided
Repeated corrected claims	Add pre-submission claim checks
Frequent payer-specific denials	Maintain a payer billing matrix
Coding variation between clinicians	Standardize workflows and staff education
Missing claim data	Validate required billing fields before submission

How to Apply Psychiatric Coding Rules in Your Practice

A reliable billing process should make correct coding easier before the claim reaches the billing queue.

1. Assess the Current Workflow

Map scheduling, documentation, charge entry, claim submission, payment posting, and denial follow-up. Identify where staff manually re-enter codes, diagnoses, telehealth status, or appointment duration.

2. Identify High-Risk Bottlenecks

Review denials and corrected claims by reason. Pay special attention to psychotherapy time mismatches, incorrect E/M-plus-psychotherapy combination, missing authorizations, telehealth POS errors, diagnosis mismatches and modifier or required claim-field errors.

3. Define System Requirements

Define what the system must capture before a psychiatric claim is submitted. This may include:

• CPT and ICD-10-CM codes
• Psychotherapy time
• E/M documentation
• Telehealth POS and modifiers
• Provider information
• Authorization details
• Claim edits and denial status

If the practice offers telepsychiatry, evaluate whether its telehealth EHR software can keep patient location, virtual visits, documentation, and billing information connected.

4. Involve Clinical and Administrative Users

Psychiatrists, PMHNPs, therapists, front-desk staff, and billers see different failure points. Clinicians identify documentation friction; billers identify recurring claim problems.

5. Test Before Rollout

Assess actual cases of diagnostic intake, Medication Only follow-up, E/M with Psychotherapy, Family Psychotherapy, Crisis Care, and Telehealth. Test templates, permissions, code selection, claim fields, and reporting to verify that they behave as expected prior to deployment in a wide manner.

6. Train Staff and Measure Results

Educate teams on the definitions and rules for writing documentation for services, not just code numbers. Monitor first-pass claim acceptance/denials, charge lag, corrected claims, days in A/R and coding-related support issues.

Prior to the migration or system replacement, verify: Payer mappings, fee schedules, patient balances, claim history and reporting, clinician permissions.

Denials can be minimized when clinical documentation and billing processes are aligned, as opposed to being corrected, from the start.

Questions to Ask Before Choosing a Psychiatric EHR and Billing Solution

Before selecting an EHR or practice management platform, ask:

1. Can the system support both psychiatric E/M and psychotherapy workflows without forcing duplicate documentation?
2. Can templates capture psychotherapy time and the clinical elements needed to support the service performed?
3. How are telehealth location, appointment type, and billing information carried into the claim workflow?
4. Can administrators configure permissions for psychiatrists, prescribers, therapists, billers, and front-desk users?
5. How does the system handle claim edits, rejected claims, patient balances, payment posting, and billing reports?
6. Can we export clinical and billing data in a usable format if we change systems later?
7. What does implementation include, and which fees apply to migration, training, billing, telehealth, or other services?
8. Can the system flag missing psychotherapy time, telehealth data, or other required claim information before submission?

Prioritize the platform that fits how the practice documents, bills, follows up, and measures revenue cycle performance.

Choosing the Right Approach to Psychiatric CPT Coding

Using CPT codes for psychiatric services correctly takes more than knowing the code numbers.

Practices need to match each code to the service in the note. They also need to record psychotherapy time, keep E/M and psychotherapy separate when both are billed, and check each payer’s telehealth rules.

A strong billing workflow can catch missing or conflicting data before a claim is sent. Focus on clear notes, current code guides, payer rules, and a system that keeps clinical and billing data linked.

Frequently Asked Questions

1. What are the most common CPT codes for psychiatric services?

Common psychiatric CPT codes include 90791 and 90792 for diagnostic evaluations, 90832, 90834, and 90837 for individual psychotherapy, and 90833, 90836, and 90838 for psychotherapy performed with an E/M service. 

Other codes may apply to family therapy, group therapy, crisis care, and interactive complexity. The correct code depends on the service provided, documented time, provider type, and payer rules.

2. What is the difference between CPT codes 90791 and 90792?

CPT 90791 describes a psychiatric diagnostic evaluation without medical services, while 90792 includes medical services performed by an appropriately qualified provider. 

The correct code depends on what occurred during the evaluation, not simply whether the patient is new to the practice. Provider eligibility and payer requirements should also be verified.

3. Can psychiatrists bill E/M and psychotherapy on the same visit?

Yes. When the E/M service and psychotherapy are significant and separately identifiable, a psychiatrist may report an appropriate E/M code with a psychotherapy add-on code such as 90833, 90836, or 90838. 

The E/M level is generally selected using medical decision-making when psychotherapy is also reported, and E/M time should not be counted as psychotherapy time.

4. Which CPT codes can be used for telepsychiatry?

Many psychiatric services may use the same core CPT codes when delivered through telehealth, depending on the service and payer. Practices must also check telehealth eligibility, audio-video or audio-only rules, place-of-service requirements, modifiers, patient location, and payer coverage. CPT recognition of telemedicine delivery does not automatically guarantee reimbursement by every payer.

5. What documentation is needed to support psychiatric CPT codes?

Documentation should support the service reported on the claim. Depending on the encounter, this may include the psychiatric assessment, medical decision-making, psychotherapy time, interventions provided, patient response, diagnoses, telehealth details, and other information required by the payer. When E/M and psychotherapy are billed together, the record should clearly support both services.
