A look at the top ICD-10 codes therapists, psychologists, social workers, and counselors are using in SimplePractice

We know there’s still a lot of questions out there in the behavioral health community about which ICD-10 codes to use for mental health diagnoses. From what we understand, some insurance payers are still determining which behavioral health codes are billable and non-billable ICD-10 codes.

We see that there is a lot of healthy debate happening among experts about how best to use the new ICD-10 code set. While we cannot weigh in on this debate because we’re software makers and not clinicians, we think it may be helpful to look at some of the data trends we’ve seen in the first few days of the ICD-10 transition. So, we’ve listed below the ICD-10 codes most frequently used by the SimplePractice community.

We need to be clear here that we are not billers and we are not clinicians so we can’t recommend which ICD-10 codes to use in your documentation. This list is just a glimpse into the frequency of use for certain codes. This is not a recommendation to use any of these codes for your documentation.

With that little disclaimer said, here are the ICD-10 codes most frequently used by the SimplePractice community.
