question about max out of pocket and deductibles?

hi, i am just starting my WLS journey. i know that my insurance will pay 50% of costs related to weight loss surgery. the question i have is this: my yearly deductible is $250.00, and the max out of pocket is $2000.00, so does that mean that if my half is over $2000.00 they (the insurance co) has to pay it even if it is more than 50%? i am new to insurance and sooo confused. here is what it says on their website:

Individual Plan Year Deductible		Individual Plan Year Out of Pocket
PPO (in-net) PPO (out-of-net) PPO (out-of-area) Lifetime Maximum: In-network Out-of-Network	$250.00 $750.00 $250.00		$2000.00 $4000.00 $2000.00 $5,000,000.00 $5,000,000.00

  the surgeon that i picked and the surgery center that he uses is in network. can some one please explain this to me? thanks so much in advance.

djgsmom, The first reply to your question was a great explanation.  One thing I might add is that you should look for exclusions in your insurance.  For example, my insurance has a $1000 deductible and $2000 max out of pocket expense and normally pay 80/20.  HOWEVER--with WLS they only pay 60/40 AND it does NOT apply to the out of pocket max.  Which means I will pay 40% of whatever the cost is PLUS the deductible no matter what it costs.
