ICD Codes for Mental Health in 2023
The WHO regularly revises the internationally recognized ICD codes, making them an even more reliable resource. But the United States has developed its own clinical modification for use in the country. It has over 70,000 codes describing diseases, signs and symptoms, abnormal findings, complaints, and external injury or illness causes.
In mental health, there are hundreds of codes for different conditions, such as
ICD codes for autism, as well as mood, anxiety, eating, and personality disorders. Some subcategories and modifiers go with each code to give more information about the diagnosed condition. As a result, the number of codes for mental health is quite extensive, especially in 2023, and continues to increase with classification system updates.
To give you an idea of how many codes there are, the "Mental, Behavioral, and Neurodevelopmental Disorders" chapter of the ICD-10-CM organizes the codes into the following three main categories:
- G Codes: These are used to categorize various factors influencing health status and healthcare delivery. They also provide additional information that could be useful for patient care, research, or reimbursement.
- Z Codes: These are used to categorize factors that influence health status and the provision of healthcare services, but they are not considered diseases or conditions in and of themselves. They also provide valuable information in patient care, research, or reimbursement.
- F Codes: These are used to categorize mental and behavioral disorders. They make up most of the ICD-10 codes for mental health, like the ICD codes for ADHD, and are used by doctors and insurance companies to document and track patient care.
Furthermore, while many codes may be used in healthcare situations, you will not encounter them all in your therapy practice. That's why we've compiled a list of the most common ICD codes for mental health in 2023, which you can find below:
