Mental Health Billing - Frequently Asked Questions
For Ontario, codes like K013, K005, K007 and K623 are the most commonly billed for mental health-related appointments.
For BC, codes such as mental health management fees (14044-14048) and in-office counselling (12120, 00120, etc.) are the most common for mental health-related visits.
Mental health-related visit codes are not billable under the LFP model, but are billable under fee-for-service.
A unit is considered 30 minutes or a major part of the half-hour counselling/mental health assessment (20 minutes).
In some instances, if you are performing two different assessments, like A007 and K005, and they are regarding two separate issues with two different diagnostic codes (and the diagnostic codes are not non-specific, like 799 etc.), and it is documented separately in the patient’s charts with clear start and end times for the mental health-related visit, then the visits can be billed together.
This applies only to specific A-prefix assessments, such as A007, A003, and A001, as well as K-prefix assessments, such as K005/K007.
For example, if a physician bills an A007 assessment with diagnostic code 307 (sleep disorder) and a K007 assessment with diagnostic code 300 (anxiety neurosis), this would be incorrect because both diagnoses fall under the same “Mental Disorders” diagnostic code table. Both assessments have to be for different issues for the claim to be paid out.
