Do Drug, alcohol treatment center falsely diagnose people as needing treatment solely for profit?

I had to attend a DWI screening at a drug and alcohol center for an evaluation ordered by the DMV of NY to get my license back, I told them the truth that I hadn’t had a drink in more than a year or done drugs in over 2 years they charged me $200 bucks then told me after 15 minutes of yes and no questions that I needed at 12 week program. That sounds sketchy to me!!! it seems like they just want your money
