The new ICD-10 codes for mental health are coming into effect in 2023, but what do they mean for you?
In addition, starting January, 1st, 2023 there are some major deletions to some of our most frequently used CPT Codes! CPT is deleting prolonged codes 99354, 99355, 99356, and 99357. These were face-to-face prolonged service codes. Many of us use these for extended sessions with our clients and particularly with our EMDR clients and family sessions that go longer than 90 min. Please take note of these major changes and change your billing accordingly.
Here is a summary of the ICD-10 updates and the DSM 5 codes.
ICD-10-CM includes an official Index and official Guidelines of mental health diagnoses. These are designed to help people coding claims to find and assign the correct diagnosis codes for their client’s conditions. Some are billable and some are not. Each year these codes get updated, just to confuse us all. lol!!

What changes do you need to make to prepare for the new codes in 2023?
You will need to change any diagnosis that has been removed from the billiable codes for ICD-10 to a more accurate diagnosis. If you were using any of the prolonged session billing codes, please take note and adjust accordingly. I’m keeping an eye on these changes and hope there will be a solution to allowing us to continue with extended sessions when justified.Â
