IPM replacement and Inverter Coolant drain/replace charges

So I recently had recall j0v done on my car because I was experiencing the inverter failure. They repaired it and replace the IPM. I'm noticing on my bill they charged me for an Inverter Coolant Service, Drain and Refill. Wouldn't this be covered under the warranty since you have to drain the inverter to work on it?? Did I just get hosed by the dealer? If so does anyone have "2011 Prius: Intelligent Power Module Transistor Removal" TIPS document that I can show the dealer the coolant needed to be drained and refilled.

I did have them replace the fender lining which they didn't replace it until I called them out on it when I was picking up the car.

I also had them Clean of HV battery air intake screen and blower. When I looked in the air intake I could still see cat hair and then I pulled the system apart and found lint, dirt and hair stuck on the blower blades.
