Your work isn’t finished when your patient leaves your office or signs off your telehealth appointment. If you bill insurance, then you’re also responsible for appropriately documenting your patients’ visits. A large part of billing includes understanding Current Procedural Terminology (CPT) codes, which healthcare providers — including psychiatrists — use to describe their services. 

There’s no way around it: The process of documentation and billing can be time-consuming. Save time (and stress) with the guide, which outlines the most common psychiatry CPT codes you’ll use to document appointments and bill insurance.

Practice in-network with confidence

Simplify insurance and save time on your entire workflow — from compliance and billing to credentialing and admin.

It’s important to use the code that most accurately reflects the time you spent with the patient to treat their condition, and ensure that documentation for the session supports the chosen code.

Diagnostic, evaluation, intake services

When you first start seeing a new patient, you’ll schedule an initial intake appointment to properly diagnose them and evaluate their mental and medical status so you can appropriately treat them. You’ll likely use one of the below codes to do so: 

  • 90792 – Psychiatric Diagnostic Evaluation With Medical Services: The most common code used for intake appointments, 90792 represents a mental health appointment that involves an evaluation and diagnosis, along with medical services (which include an exam, prescribing, or evaluating existing medication). For that reason, it can only be used by psychiatrists, psychiatric nurse practitioners, and clinical psychologists.
  • 90791 – Psychiatric Diagnostic Evaluation: It’s less common for psychiatrists to use 90791 because it doesn’t include a core component of psychiatry, the medical services component. For that reason, it’s primarily used by counselors, social workers, and marriage and family therapists.

Evaluation and management (E/M) services

This category of CPT codes represents the crux of a psychiatrist’s work: office visits for evaluation and management (E/M) services. In the behavioral health realm, this group of codes may encompass any of the following medical services: 

  • Clinical interview
  • Interpreting symptoms 
  • Forming a diagnosis
  • Completing a physical or mental status exam 
  • Medical decision-making
  • Prescribing
  • Ordering labs or other tests

The most common E/M codes psychiatrists use include: 

New patient visits

  • 99202 – Office or Other Outpatient Visits for the Evaluation and Management of a New Patient: Code 99202 represents an E/M appointment with a new patient lasting 15-29 minutes.
  • 99203 – Office or Other Outpatient Visits for the Evaluation and Management of a New Patient: Code 99203 represents an E/M appointment with a new patient lasting 30-44 minutes.
  • 99204 – Office or Other Outpatient Visits for the Evaluation and Management of a New Patient: Code 99204 represents an E/M appointment with a new patient lasting 45-49 minutes.
  • 99205 – Office or Other Outpatient Visits for the Evaluation and Management of a New Patient: Code 99205 represents an E/M appointment with a new patient lasting 60-74 minutes.

Established patient visits

  • 99212 – Established patient office or other outpatient visit: Code 99212 represents an E/M appointment with an established patient lasting 10-19 minutes.
  • 99213 – Established patient office or other outpatient visit: Code 99213 represents an E/M appointment with an established patient lasting 20-29 minutes.
  • 99214 –  Established patient office or other outpatient visit: Code 99214 represents an E/M appointment with an established patient lasting 30-39 minutes. This longer visit usually includes medical decision making in more complex cases.
  • 99215 – Established patient office or other outpatient visit: Code 99215 represents an E/M appointment with an established patient lasting 40-54 minutes. This longer visit usually includes medical decision making in more complex cases.

It’s important to note that these codes can’t be combined with the diagnostic/evaluation codes 90792 or 90791. They can be billed alone or include add-on codes for psychotherapy, which are outlined below. 

Psychotherapy services

If you also provide psychotherapy services in addition to evaluation and management — which may include providing non-pharmaceutical coping skills for your patients’ symptoms — you can add on psychotherapy codes in your documentation. Due to the nature of a psychiatrist’s training and specialty, it’s unlikely you’d provide psychotherapy alone without an E/M element.

Psychotherapy codes are add-on codes defined by time. You may use any of the below codes in conjunction with E/M codes:

  • 90833 – Evaluation and Management with 30 Minutes Psychotherapy: Code 90833 represents an E/M appointment with 16-37 minutes of psychotherapy.
  • 90836 – Evaluation and Management with 45 Minutes Psychotherapy: Code 90836 represents an E/M appointment with 38-52 minutes of psychotherapy.
  • 90838 – Evaluation and Management with 60 Minutes Psychotherapy: Code 90838 represents an E/M appointment with 53 minutes or more of psychotherapy.

No matter which CPT codes you use, be sure to include all the applicable codes in a single claim when you file — along with the appropriate documentation that supports the CPT code — for more efficient claim approval and reimbursement for services rendered.

Tips for using psychiatry CPT codes in documentation

Nothing slows down a psychiatrist’s workflow like a delayed, rejected, or clawed-back claim. Correctly using CPT codes in documentation helps reduce the possibility of those annoying outcomes. As you complete your documentation, keep these tips in mind.

  • Support your code selection through documentation. Each piece of documentation you create, including progress notes and treatment plans, should include a CPT code to reflect the services provided. To stay in compliance, make sure the other elements of your notes back up your code selections. For example, if you use code 99215 (for an E/M visit lasting 40-54 minutes), your session details should corroborate the length of the appointment.
  • Remember medical necessity. For seamless billing, your documentation should tell a cohesive story about why certain services were necessary, and thus why certain codes were selected. For example, if you used CPT code 90839 (psychotherapy for crisis), your progress note should include specific details, such as quotes or observed behaviors, that show your client was indeed in crisis.
  • Make sure your codes work together. Properly using add-on or modifier codes can increase the overall accuracy and robustness of your coding. On the other hand, some codes cannot be used together because they reflect mutually exclusive services. Always double check that you’ve picked the code(s) that best reflect the services provided, while remaining compliant.
