Psychiatric care often occurs outside of traditional office visits. Caring for patients between visits does not eliminate professional responsibility. Clinical decision-making via secure messages, email, or other HIPAA-compliant platforms still requires documentation and clinician time and carries malpractice risk. When clinicians evaluate symptoms, manage medications, assess safety, or make treatment decisions outside scheduled appointments, that work should be documented and reimbursed.
The American Medical Association introduced the Online Digital Evaluation and Management codes in 2020. With the AMA CPT 2026 code set and the CMS 2026 Physician Fee Schedule, both continue to recognize and reimburse non-face-to-face clinical work. One of the most relevant pathways for mental health clinicians outside of office visits is Online Digital E/M.
Online Digital E/M services are reported using CPT 99421, 99422, and 99423. They allow physicians and qualified healthcare professionals, such as nurse practitioners and physician assistants (physician associates), to bill for asynchronous, patient-initiated digital care that involves true evaluation, assessment, and management.
This article explains how Online Digital E/M applies specifically to psychiatric practices in 2026 and how PMHScribe supports compliant documentation of these services.
Why Online Digital E/M Is Especially Relevant in Psychiatry
Psychiatry routinely involves clinical decision-making that occurs between visits. Common examples include reviewing patient portal messages about worsening mood, managing medication side effects, adjusting doses, ordering labs, or responding to concerns about sleep, anxiety, attention, or suicidality.
Historically, much of this work went undocumented or unpaid. Online Digital E/M codes formally recognize this work when it meets defined criteria and is properly documented.
What Are Online Digital E/M Services
Online Digital E/M services are patient-initiated, asynchronous services provided to established patients through HIPAA-compliant digital platforms such as EHR portals, secure email, or secure messaging applications.
These services require evaluation, assessment, and management by a psychiatrist, psychiatric nurse practitioner, or physician assistant. They are not intended for administrative communication, such as scheduling, prescription refill requests without evaluation, or relaying normal test results without interpretation.
Although the patient’s problem may be new, the patient must be established with the clinician or group practice.
Online Digital E/M services are reported once per seven-day period based on cumulative clinician time.
CPT Codes and Time Thresholds for Online Digital E/M
Online Digital E/M services are time-based and cumulative over a seven-day period that begins with the clinician’s initial personal review of the patient-initiated inquiry.
- CPT 99421: 5 to 10 minutes
- CPT 99422: 11 to 20 minutes
- CPT 99423: 21 minutes or more
Do not report Online Digital E/M for less than five minutes. These codes are listed in the 2026 CMS Physician Fee Schedule.
What Psychiatric Work Counts Toward Cumulative Time
For psychiatrists, psychiatric mental health nurse practitioners, and physician associates, cumulative time may include:
- Review of the initial patient inquiry
- Review of relevant psychiatric history, prior notes, or data
- Assessment of symptoms, risk, and treatment response
- Clinical decision-making regarding medications or therapy
- Communication with clinical staff focused on the patient’s psychiatric problem
- Ordering labs, tests, or referrals
- Generating or adjusting prescriptions
- And the subsequent communication with the patient through secure messaging, email, telephone, or other digital communication
Clinical staff time does not count toward cumulative time. All professional work by clinicians within the same specialty and group practice related to the patient’s problem is included in the cumulative time.
Psychiatry-Specific Documentation Requirements
Online Digital E/M services require a chart note.
For psychiatrists, psychiatric mental health nurse practitioners, and physician associates, documentation should clearly reflect:
- That the service was patient-initiated
- The psychiatric assessment was performed
- Clinical reasoning and medical decision making
- Medication management or treatment decisions
- Orders placed or prescriptions written
- Time spent cumulatively during the seven-day period
- The mode of digital communication used
Relationship to Telepsychiatry and Other E/M Services
In 2025, traditional telephone E/M codes were replaced with synchronous audio-only telemedicine E/M visit codes. These are the codes for videoconferencing visits and telephone call visits.
Audio-Video Telemedicine E/M services CPT are 98000 through 98007.
Audio-Only Telemedicine E/M services are CPT 98008 through 98016.
If a synchronous telemedicine visit occurs within seven days of initiating an Online Digital E/M service, the digital work is incorporated into the separately reported E/M visit and is not billed separately.
If a patient initiates an Online Digital E/M inquiry for a new problem within seven days of a prior E/M visit that addressed a different problem, the Online Digital E/M service may be reported separately.
If a new, unrelated problem arises during the seven-day Online Digital E/M period, the clinician’s time spent managing that problem may be added to the cumulative time.
Common Reporting Limitations and Exclusions
Report CPT 99421 – 99423 only once per seven-day period.
Do not report Online Digital E/M on the same day as another E/M service.
Administrative Burden in Psychiatric Practices
Despite being clinically appropriate, Online Digital E/M services can be difficult to track. They still require a chart note to bill and recall interim care.
Without purpose-built tools, Online Digital E/M work is often under-documented, missed entirely, and not billed.
How PMHScribe Supports Online Digital E/M in Psychiatry
PMHScribe is designed specifically for psychiatric and mental health workflows.
PMHScribe helps psychiatrists, psychiatric mental health nurse practitioners, and physician associates generate structured Online Digital E/M documentation that aligns with CPT 99421, 99422, and 99423 requirements. Copy and paste portal messages into PMHScribe, click the Online Digital E/M (Portal Messages) in the Practice Tools Section to generate an appropriate chart note.
The platform supports permanent documentation storage, organizes notes around psychiatric assessment and medical decision-making, and reduces the manual burden of documenting asynchronous care.
By aligning documentation with CPT and CMS guidance, PMHScribe helps mental health clinicians capture legitimate, reimbursable non-face-to-face work without increasing charting time.
Final Takeaway
Online Digital E/M services are now a core component of psychiatric care. CPT 99421, 99422, and 99423 provide a compliant mechanism to document and bill for asynchronous psychiatric evaluation and management that already occurs every day.
The key to success in 2026 is understanding the rules, documenting appropriately, and using tools designed for psychiatric practice.
