I got 2 visits covered per week for a while (I think 3 months or so) when I had just gotten out of the hospital and was under a lot of stress at work. However my insurance then suddenly turned on me and required my therapist send in a ton of paperwork proving I needed treatment. Based on that they said that I had an incurable disorder (bipolar I) and could not benefit from treatment due to a lack of insight (my therapist absolutely did not agree with this and he had been treating me for 4 years at the time so knew me well) and so they were reducing it to once a month. We fought and got twice a month and my therapist's office gave me a reduced rate for the other 2 visits (I was ready to go to weekly by the end of that battle).

I know when there is marriage/family therapy one person has to be the patient and that is submitted with a diagnostic code. I don't know how they determine that the 2 kinds of treatment are beneficial to the one person, but I do know it is billed that way. Perhaps they billed it as your spouse having issues coping with your disorder? I have no idea.
