I don't quite get why you're paying her less this year than last year? Because your husband thinks she's getting too much money from the Ins. Company? Because that's really none of his business and shouln't dictate what your co-pay amount is. Just because the insurance codes changed, it doesn't mean she is getting something "special". It means she is being better compensated for your extended sessions.

Also, from a business perspective, you're basically taking up 2 session times - she could see two people for 45 minutes in that amount of time and make more money. That's why the 90 minute session isn't the cost of one and half 60 minute sessions.
