What are CPT codes for mental health?

CPT (Current Procedural Terminology) codes are standardized five-digit codes developed by the AMA that describe the medical services a provider delivers. Mental health CPT codes specifically cover psychotherapy sessions, psychiatric evaluations, psychological testing, crisis intervention , and related behavioral health services. They are required on every insurance claim to receive reimbursement.

What are the most common psychotherapy CPT codes?

The three most commonly used psychotherapy codes are 90832 (30 minutes of individual psychotherapy, for sessions lasting 16–37 minutes), 90834 (45 minutes, for sessions lasting 38–52 minutes), and 90837 (60 minutes, for sessions lasting 53 minutes or longer). Other frequently used codes include 90846 and 90847 for family psychotherapy and 90853 for group psychotherapy.

Are telehealth therapy sessions billed the same as in-person visits?

Yes. According to CMS, telehealth visits use the same CPT codes and are reimbursed at the same rates as in-person sessions. The difference is that you add modifier 95 (or GT) to indicate a real-time telecommunication interaction and use Place of Service code 02 instead of 11.

What CPT code should I use for an initial psychiatric evaluation?

Use 90791 for a psychiatric diagnostic evaluation without medical services, or 90792 for a psychiatric diagnostic evaluation with medical services. Depending on the complexity and time involved, you may also bill an E/M code (such as 99202–99205 for new patients) alongside the evaluation code.

What is the difference between CPT codes and ICD codes?

ICD codes describe the patient's diagnosis — the reason treatment is necessary (such as F41.9 for anxiety disorder). CPT codes describe the specific service provided (such as 90834 for a 45-minute psychotherapy session). Both are required on insurance claims: ICD codes justify medical necessity, and CPT codes specify what services were delivered.

What CPT codes are most commonly missed by mental health providers?

Many providers overlook add-on codes like 90785 (interactive complexity) and 90840 (crisis psychotherapy add-on). Missing these reduces reimbursement and underreports services. Reviewing the latest AMA CPT updates regularly ensures all eligible services are captured accurately.

How often are mental health CPT codes updated?

The American Medical Association updates CPT codes annually, typically each January. These updates can redefine time-based codes, introduce new procedures, or revise descriptions for greater accuracy. Behavioral health professionals should review changes every year to ensure compliance and reimbursement accuracy.

What’s the best way to document medical necessity for psychotherapy sessions?

Documentation should include the diagnosis, treatment goals, patient progress, and clinical justification for ongoing therapy. Insurers often require evidence that sessions address functional impairment. Linking ICD codes directly to CPT procedures reinforces medical necessity in the billing record.

Can multiple CPT codes be billed during the same therapy session?

Yes, but only when distinct services are provided and separately documented. For instance, you may bill both a psychotherapy and an E/M code if you evaluate medication during the same encounter. Clearly note separate times and purposes for each service in the clinical record.

Are there CPT codes specific to group telehealth therapy?

Group telehealth psychotherapy uses CPT code 90853 with a telehealth modifier (95 or GT). The Place of Service code should be “02” to indicate telecommunication delivery. Billing requirements mirror in-person sessions, but documentation must state that the session occurred via secure video conferencing.

When is a clinician obligated to breach confidentiality due to a threat of harm (Tarasoff principle)?

Under the Tarasoff principle , clinicians may have a legal and ethical duty to breach confidentiality if a client poses a serious and imminent threat of harm to an identifiable person. This duty, often summarized as a "duty to warn" or "duty to protect," originates from the 1976 Tarasoff v. Regents of the University of California case and is now codified in many states. Obligations may include warning the potential victim, notifying law enforcement, or taking other reasonable steps to prevent harm. However, laws vary by state: some mandate action, while others permit it. Clinicians should be familiar with their state’s laws and document all decisions carefully. Consulting with a supervisor or legal advisor is recommended in high-risk cases. Tip: Laws regarding duty to warn and protect vary widely. Some states mandate it, others permit it, and a few offer no clear guidance. The Psych Law GAP resource provides an overview of the Tarasoff duty to warn/protect and specifically links to a detailed compilation of each state's relevant statutes and regulations as of February 2020, making it a reliable resource for state-by-state legal differences. The National Conference of State Legislatures (NCSL) also provides a concise summary and table of state-specific laws on the duty to warn and protect, highlighting where states have mandatory, permissive, or no explicit duty.

How can clinicians minimize legal risk when handling suicidal or self-harm patients?

To reduce legal risk while treating clients with suicidal ideation or self-harming behaviors, clinicians should document thoroughly, follow clinical best practices, and take timely, appropriate action. Key strategies include: Use standardized risk assessment tools , such as the Columbia Suicide Severity Rating Scale (C-SSRS), and document both the results and your clinical interpretation. Create a collaborative safety plan when appropriate, and include it in the client’s record. Consult with supervisors or colleagues when facing uncertainty about risk level or next steps. Refer to higher levels of care or initiate emergency interventions when risk is imminent and beyond your scope. Document all actions taken , including client statements, safety planning, informed consent, referrals, and attempts to contact emergency contacts or crisis services. Careful documentation is your strongest legal defense. If it’s not written down, it may not be considered to have happened in the eyes of an auditor, board, or court.

What is the legal risk for medication errors in psychiatric practice?

Medication errors, such as prescribing the wrong drug, dose, or failing to monitor side effects, can expose psychiatric clinicians to significant legal risk, including malpractice lawsuits, licensing board complaints, and even criminal charges in extreme cases. Common legal claims involve: Failure to obtain a full medical or medication history Incorrect dosing or drug interactions Failure to monitor for adverse effects or suicidal ideation Lack of informed consent for medication risks To reduce liability: Always document informed consent discussions, including risks, benefits, and alternatives. Use evidence-based prescribing guidelines and regularly monitor client response and lab work. Coordinate with primary care or other treating providers when appropriate. Review medication reconciliation at each visit, especially after hospital discharge. Psychiatric medication errors are a leading source of malpractice claims involving patient harm, particularly when documentation is incomplete.

How can clinicians protect patient records during litigation/discovery?

When clinicians are subpoenaed or involved in litigation, protecting patient confidentiality is critical, even when disclosure is legally requested. Patient records carry different degrees of privacy , and clinicians must understand what can and cannot be shared. Degrees of privacy include: Standard clinical records (e.g., progress notes, treatment plans) are generally discoverable if subpoenaed, but only the minimum necessary should be disclosed. Psychotherapy notes , as defined by HIPAA, are held to a higher standard and are not automatically part of the legal medical record . These notes must be kept separate and require a court order (not just a subpoena) for disclosure. Substance use records (42 CFR Part 2) and information related to HIV status, reproductive health, or minors may have additional legal protections and state-specific disclosure restrictions. Practical tips to protect client records: Never release records without client consent or verifying legal authority. If you receive a subpoena, consult legal counsel or your professional liability carrier before responding. Redact information that is not relevant to the legal matter. For example, if only treatment attendance is requested, avoid sharing full clinical notes. Document your actions carefully. Note any subpoenas received, legal consultations made, and exactly what was disclosed. Use an EHR that supports record segmentation (like separating psychotherapy notes) and tracks access for audit purposes. Example: A therapist receives a subpoena in a custody dispute requesting all client records. Because the client is not a party to the dispute, the therapist consults legal counsel, who helps limit disclosure to session attendance dates and general treatment goals—protecting sensitive clinical content from unnecessary exposure.

When (and what) should I communicate to other providers or families about a patient’s risk status?

When (and what) should I communicate to other providers or families about a patient’s risk status? Clinicians have both ethical and legal responsibilities when a client presents with suicidal ideation, self-harm, or danger to others. Sharing information must balance confidentiality with duty of care , and your actions should be based on the immediacy of risk , the client's age or capacity, and applicable laws. Communicate risk when: The client is at imminent risk of harm to self or others The client is a minor and parental/guardian involvement is legally or clinically appropriate Another provider (e.g., primary care, psychiatrist) is involved in care and coordination is essential for safety You're making a referral to a higher level of care , such as inpatient treatment What to communicate: The level and nature of risk (e.g., suicidal ideation with plan and intent) Steps already taken , such as safety planning or emergency referrals Recommendations for follow-up care Only the minimum necessary information to ensure continuity of care or safety Examples: If a client expresses active suicidal intent and refuses voluntary hospitalization, you may be required to inform emergency services and, if relevant, family members involved in their care. If you're referring a client to a psychiatrist for medication, sharing your clinical impressions and any known safety concerns supports coordinated treatment, and helps prevent medication errors. Tip: Always document the reason for the communication, what was shared, with whom, and whether the client consented or was informed (unless doing so would increase risk).

How do I set effective goals and objectives in a treatment plan?

To set effective goals and objectives in a behavioral health treatment plan, start with the client’s presenting problem and collaboratively define broad, meaningful goals. Break each goal into SMART objectives—specific, measurable, attainable, relevant, and time-bound steps. These guide interventions, support measurable progress, and fulfill documentation and insurance requirements. ICANotes simplifies this process with diagnosis-linked goal libraries and built-in tracking tools.

What are best practices for involving clients in treatment planning?

Involving clients in treatment planning improves engagement, outcomes, and adherence by making them active partners in their care. Best practices include using open-ended questions, translating client goals into clinical language, co-creating SMART objectives, and regularly revisiting the plan. ICANotes supports collaborative planning with editable templates, built-in client participation fields, and tools for tracking progress together.

How often should treatment plans be reviewed or updated?

Treatment plans should typically be reviewed every 90 days in outpatient settings and every 30 days in higher levels of care like IOP or PHP. Plans should also be updated immediately when there are significant clinical changes, such as a new diagnosis, progress toward goals, or a client crisis. ICANotes supports timely reviews with built-in reminders, progress tracking, and customizable templates.

How do I document progress and outcomes in a treatment plan?

To document progress and outcomes in a mental health treatment plan, track whether each objective is met, partially met, or unmet, include client self-reports, clinical observations, and use standardized tools like the PHQ-9 or GAD-7 to show measurable change. Update goals as needed based on progress. ICANotes streamlines this with structured templates, built-in outcome tracking, and audit-ready formatting.
