Mental health billing can feel confusing because small details change everything. Time, setting, provider type, and payer rules can affect the correct code.
It also depends on whether the visit included psychotherapy, medication management, or both.
If you have searched mental health CPT codes, wondered about the 90832 time range, or asked what it covers, this guide helps. You will get a practical list of common CPT codes for mental and behavioral health. You will also get step-by-step tips to reduce denials and keep documentation aligned.

Always confirm current payer policies and state guidance, and consult qualified coding or compliance professionals when needed.
Understanding Mental Health Billing Codes
Medical billing, in day-to-day practice, translates what happened in a visit into a claim a payer can process. Most mental health billing codes rely on three building blocks:
- CPT codes for mental health: The procedure or service performed.
- HCPCS codes (often called H codes): Common in Medicaid and community behavioral health programs.
- ICD-10 diagnosis codes: The clinical reason for the service (reported at a high level).
Many teams use the term “therapy CPT codes” to refer to all codes used for therapy services. In practice, outpatient psychotherapy often uses CPT codes.
Some programs use HCPCS codes, such as H0035, based on payer and state rules.
How to Use This Guide?
Use the code list below as a starting point, then apply payer-specific rules.
- Start with the service type: evaluation, psychotherapy, group, family, crisis, or add-on to an E/M visit.
- Confirm who provided the service and what your contract allows.
- Confirm time and session format when time-based rules apply.
- Confirm telehealth requirements (place of service and modifiers).
- Confirm authorization status and remaining units or visits.
This workflow prevents many common denials in medical billing and keeps documentation and coding aligned.

Common CPT Codes for Mental Health
Diagnostic Evaluation Codes
90791
Simple description: Psychiatric diagnostic evaluation without medical services.
When it is typically used:
- Initial assessment focused on diagnosis, history, and treatment planning.
Documentation basics:
- Presenting problem and relevant history
- Mental status exam or equivalent observations
- Diagnostic impression and treatment plan
- Medical necessity and next steps
90792
Simple description: Psychiatric diagnostic evaluation with medical services.
When it is typically used:
- An initial assessment that includes medical services such as medication evaluation or related medical decision-making.
Documentation basics:
- All elements of 90791 plus relevant medical decision-making details
- Medication history and risk considerations when applicable
Psychotherapy Codes (Standalone)
CPT 90832
90832 CPT code description: Psychotherapy, typically 30 minutes.
90832 time range: Many payers use common psychotherapy time thresholds. They place 90832 in a shorter time window. This is often around the mid-teens to mid-thirties in psychotherapy minutes. Exact rules can vary, so confirm payer guidance.
Documentation basics:
- Total time or start and stop times when required
- Interventions used and clinical focus
- Patient response and progress
- Plan for next session
90834
Simple description: Psychotherapy, typically 45 minutes.
Documentation basics:
- Therapy interventions and patient response
- Progress toward goals and continued medical necessity
90837
Simple description: Psychotherapy, typically 60 minutes.
Documentation basics:
- Clear justification for extended time when required by the payer
- Strong linkage to goals, symptoms, and medical necessity
Note on search intent.
If you are searching for a CPT code for 30-minute psychotherapy, the answer is often CPT 90832. Always verify the payer’s time policy. Also, check any limits based on provider type and setting.
Psychotherapy Add-On Codes With E/M
- Providers often use these when a qualified prescriber provides an E/M service.
- This is often medication management.
- The prescriber also provides psychotherapy on the same date. Many payers require documentation that clearly supports both components without double-counting time.
90833
Simple description: Psychotherapy add-on, typically 30 minutes, performed with an E/M service.
Why it matters:
- Not a standalone psychotherapy code.
- Documentation should support E/M work and psychotherapy work separately.
90836
90836 cpt code: Psychotherapy add-on, typically 45 minutes, performed with an E/M service.
Common billing risk:
- Billing an add-on code without an eligible primary E/M service.
90838
90838 cpt code: Psychotherapy add-on, typically 60 minutes, performed with an E/M service.
Documentation basics for add-on psychotherapy
- E/M documentation as applicable (medical decision-making and medication work)
- Separate psychotherapy time and interventions
- Clear note structure showing that both services occurred
Medication management CPT code
Many teams search the CPT code for medication management. In modern billing, prescribers often document medication management with E/M codes. There is no single universal CPT code for psychotherapy. Some payers still recognize specific add-on reporting in limited contexts. Always follow payer policy and your credentialing rules.
Crisis Psychotherapy Codes
CPT 90839
Simple description: Crisis psychotherapy, first 60 minutes.
CPT 90840
90840 cpt code description: Crisis psychotherapy, each additional 30 minutes.
Common pitfalls:
- Not documenting why the situation qualified as a crisis
- Missing time documentation when required
- Not including safety planning and risk assessment details
Group and Family Psychotherapy
CPT 90853
90853 cpt code description: Group psychotherapy.
Documentation basics:
- Group topic or focus and interventions used
- Attendance and patient participation
- Patient response and progress
90846
90846 cpt code description: Family psychotherapy without the patient present.
Documentation basics:
- Clinical purpose of family-only session
- Connection to the patient’s treatment plan and goals
Other Commonly Searched Behavioral Health CPT Codes
Interactive Complexity
CPT code 90785 description: Interactive complexity add-on used when communication factors complicate delivery of the primary service.
Key reminder:
- Payers may restrict when 90785 is allowed.
- Documentation must clearly describe what made the encounter more complex.
Communication, Reporting, and Unlisted Services
90887
- 90887 cpt code description: Communication with family or responsible parties, or interpretation and explanation of results in certain contexts beyond routine discussion.
90889
- CPT 90889: Preparation of a report or related work in limited payer-allowed contexts.
90899
- 90899 cpt code: Unlisted psychiatric service or procedure.
Why it matters:
- Unlisted codes often require additional documentation, a service description, and, sometimes, manual review.
Pharmacologic Add-On
CPT code 90863
Simple description: Pharmacologic management add-on used in specific situations when allowed by payer policy.
Important note:
- Many payers use E/M codes for medication management. Verify when 90863 is appropriate.
Assessment and Health Behavior Codes
96112 cpt code description
Simple description: Developmental test administration in appropriate contexts.
Use with care:
- Coverage and required components vary by payer and setting.
96158 cpt code description
Simple description: Health behavior intervention services in certain contexts related to behavior affecting a medical condition.
Important note:
- This is not a general psychotherapy code and has specific payer rules.
MMSE CPT code
Many teams search for an MMSE CPT code. No single universal MMSE-specific code always applies. Whether you can report it separately depends on what you did, how you documented it, and the payer policy.
Biofeedback, Hypnosis, and Other Specialized Codes
These codes are often payer-restricted and may be uncommon in standard outpatient therapy workflows.
90901 cpt code
- 90901 cpt code description: Biofeedback training.
- 90875 cpt code and 90876 cpt code
- 90875 cpt code description and 90876 cpt code description: Psychophysiological therapy with biofeedback in certain contexts. Coverage and documentation requirements vary.
Hypnosis cpt code and hypnotherapy cpt code
Some code sets include CPT 90880 for hypnosis or hypnotherapy services. Payers vary in what they accept, and they may offer limited coverage. Confirm the current code status and payer policy before using.
CPT 90870 and CPT 90867
You may see searches like cpt 90870, cpt code 90870, 90870 cpt code description, or 90867 reimbursement rate. You can associate these codes with specialized procedures, and they may require strict coverage criteria, credentialing, and documentation. Confirm payer policy before scheduling and billing.
CPT 90882
You may also see the 90882 cpt code referenced in certain contexts. As with any less-common code, confirm it is appropriate for the service performed and covered by the payer.

Behavioral Health HCPCS Codes (H Codes) Often Used With Medicaid
Many practices also work with HCPCS codes. These appear frequently in searches like h0030 cpt code description, h0032 cpt code description, and h2019 cpt code description. Program-defined services, especially in Medicaid and community behavioral health, commonly tie to these.
Important note
HCPCS code definitions and allowed settings can vary by state Medicaid program and managed care organization. Always confirm your state and payer guidance.
Common examples you may encounter
- H0030: Behavioral health-related services in certain program contexts (payer-defined)
- H0031: Assessment services in certain behavioral health programs (payer-defined)
- H0032: Treatment plan development or service plan work (payer-defined)
- H0033: Medication-related services in certain programs (payer-defined)
- H0035: Partial hospitalization or day treatment program services (payer-defined)
- H2014: Skills training and development (payer-defined)
- H2017: Psychosocial rehabilitation services (payer-defined)
- H2019: Therapeutic behavioral services or structured interventions (payer-defined)
- H2010: Comprehensive medication services in certain programs (payer-defined)
- H0018: Structured behavioral health services in certain settings (payer-defined)
- H0020: Program-related alcohol and drug services in certain contexts (payer-defined)
- S9480: Intensive outpatient psychiatric services in certain payer contexts
These codes are often unit-based and closely tied to authorization rules, making tracking and documentation essential.
Telehealth Billing Considerations
Telehealth billing is not just “use the same code.” Many payers require:
- A specific place of service for telehealth
- A telehealth modifier (payer-defined)
- Clear documentation of modality and relevant locations when required
Even when the primary CPT code for mental health is correct, claims may be denied. This can happen if the telehealth place of service or modifier does not match the payer rules.
Types of Modifiers in Medical Billing (High Level)
People often search for modifier types in medical billing or for different types of modifiers in medical billing. The key idea is that modifiers add context that can affect payment.
Common modifier concepts in mental health claims
- Telehealth modifiers, when required by the payer
- Modifiers that clarify distinct services on the same day (used carefully)
- Modifiers that clarify provider role, supervision, or setting when applicable
How many types of modifiers in medical billing are there? Many. The practical best practice is to keep a payer-specific guide for your most common services. It should include modifier rules and place of service requirements.

Step-by-Step: Choosing the Right CPT Code for a Session
Step 1: Identify the service type
Was it a diagnostic evaluation, psychotherapy, group, family, crisis, or psychotherapy plus an E/M visit?
Step 2: Confirm the provider and payer rules
Some payers restrict certain psychiatry CPT codes, add-on codes, or specialized codes based on credentials, supervision, and contract.
Step 3: Confirm time and format
- For psychotherapy codes, confirm the session length and payer time thresholds.
- For telehealth, confirm the place of service and telehealth modifier rules.
Step 4: Check authorization and eligibility
- Confirm eligibility for the date of service.
- Confirm prior authorization if required.
- Track remaining units or visits for authorized services.
Step 5: Match documentation to the code
A simple internal checklist helps prevent denials:
- Medical necessity is clear
- The service performed matches the code
- Interventions and patient response are documented
- Time is documented when required
- The note supports modifiers and telehealth details
Step 6: Submit clean claims and resolve issues fast
Many rejections happen due to the basics:
- Member ID or demographic mismatches
- Rendering provider NPI, taxonomy, or credentialing mismatches
- Incorrect place of service or missing modifier
- Missing diagnosis linkage or required fields
At Zee Medical Billing LLC, we often see the fastest AR improvement from tighter front-end steps. Focus on eligibility checks and authorization tracking before sessions add up.
Common Denial Reasons in Behavioral Health Claims
Types of rejections in medical billing usually happen before the payer adjudicates the claim. Types of denials in medical billing happen after adjudication.
Common rejection patterns
- Patient data mismatches (member ID, DOB)
- Missing identifiers (NPI, taxonomy)
- Invalid modifier or place of service
Common denial patterns
- Eligibility or coverage issues
- Authorization missing, expired, or exceeded
- Telehealth requirements not met (POS or modifier mismatch)
- Documentation or medical necessity issues
- Timely filing limits exceeded
When denial trends repeat, the fix is usually process-based. Improve front-end checks, standardize documentation, and follow payer-specific coding rules.
Compliance-Minded Documentation Basics (HIPAA-Aware)
Mental health documentation needs to be clear while staying HIPAA-aware.
Practical tips
- Keep billing-facing documentation focused on medical necessity, service delivered, and progress.
- Use secure tools for billing communication and limit access to PHI to the minimum necessary.
- Separate psychotherapy notes when applicable and ensure role-based access controls.
FAQs
What are mental health CPT codes, and which ones are most common?
Mental health CPT codes describe services like diagnostic evaluations (90791, 90792) and psychotherapy (90832, 90834, 90837). They also include crisis psychotherapy (90839, 90840), group therapy (90853), and family therapy (90846) when the patient is absent. The most common set depends on your payer mix, provider credentials, and whether you offer telehealth.
What time range does the 90832 code cover, and what documentation should we include for billing 90832?
People commonly use 90832 for a shorter psychotherapy session. Many payers use standard psychotherapy time thresholds. They place 90832 in a mid-teens to mid-thirties minute range.
Exact requirements can vary. For the 90832 billing code, document medical necessity. Note the therapy interventions used. Describe the patient’s response. Record progress toward goals. Include time if required by payer policy.
What is the difference between the 90836 CPT code and the 90838 CPT code?
Both 90836 and 90838 are psychotherapy add-on codes typically used with an E/M service on the same day. The difference is usually the typical time for psychotherapy associated with the add-on. Payers expect notes that support both the E/M part (often medication management) and the psychotherapy part.
They also expect a clear separation to avoid counting the same time twice.
How do HCPCS H codes like h0035 cpt code and h2019 cpt code fit into behavioral health billing?
Medicaid or community behavioral health programs often use HCPCS H codes. They cover program-defined services like day treatment (H0035) or structured therapeutic services (H2019). Definitions, allowed settings, and documentation rules can vary by state and managed care plan. Confirm the exact meaning and billing rules with your payer and state guidance.
What should I do if they deny my mental health claim because of authorization or telehealth issues?
Start by confirming eligibility for the service date. Then check if the action required authorization. Also, confirm that no one exceeded the approved visits or units. For telehealth denials, confirm the payer’s place-of-service and telehealth modifier rules.
Ensure the documentation supports the telehealth modality. If they rejected the claim (did not adjudicate it), correct the missing data and resubmit it. If the payer denied it after adjudication, follow the payer’s correction or appeal process and track deadlines.
Conclusion
- A strong mental health CPT code workflow is not about memorizing codes.
- Matching the right code to the right service is important.
- Your documentation should support medical need, time spent, and payer rules.
- Start with common mental health CPT codes.
- Use 90791 and 90792 for diagnostic evaluations.
- Use 90832 for psychotherapy.
- Use add-on codes 90836 and 90838 with psychotherapy and an E/M service.
- Use 90853 for group therapy.
Then reinforce the process with eligibility checks, authorization tracking, correct telehealth setup, and clean claim submission practices that reduce rejections and denials.
