Yes. Therapists "use" the diagnosis to get the best coverage they can for the client. That is not saying, they make things up. They simply work the system.

For example, most therapists will not list something like Borderline Personality Disorder as a diagnosis, because this is a red flag for insurance companies. It means long term treatment and slow progress. Insurance companies do not want to see that.

Instead, a therapist might use a diagnosis that can be associated with BPD such as depression, anxiety, etc. Or they put something like PTSD, which indicates that it "can be treated. " PTSD has many similar symptoms as BPD.

I would not worry about it. Therapists with experience know what to do to get the best coverage for you. Additionally, I would not be concerned if an insurance company has a diagnosis. Who cares? Truth is the people making the coverage decisions are not PhDs and are not therapists. They are just following protocol and could care less about you and your diagnosis.

Furthermore, the insurance company can not break confidentiality.
