Out of pocket max health plan

I was wondering if anyone could provide any insight on insurance. I am getting a vaginoplasty in june and have this week to finalize my blue shield of California insurance and what im trying to decide is weither to get gold ppo which comes with a $800 monthly premium $0 deductible and about 9k out of pocket maximum and covers 30% co insurance for most things. with the other option being a bronze high deductible health plan at 500 monthly premium, a 7k deductible and a 7k out of pocket max, so basically pay 7k then everything is covered. I understand every where is gonna be different, but im just wondering if those that recieved the procedure already, found that they hit there yearly out of pocket max. the way I see it, is the average cost of the procedure on self pay is like 150k and even if the insurance can negotiate that down to say 40k id still hit the more expensive out of pocket maximum so going on the 500/mo premium would be much more beneficial. and help is very welcomed.
