Contact Notes are non-clinical notes used to document communication between the therapist and a client or a client's contact. This could be about scheduling, homework assignments, billing, and any other communication held outside of the therapy session. There is NO CHARGE to the client for time spent communicating with them about the above issues, therefore there is no revenue earned for the clinician. It’s best to keep calls under 10 minutes.
However, if you’d like to bill the client and/or their insurance for treatment that was conducted over the phone, read this doc: How to bill Teletherapy (Audio Only) Sessions.
