Use an in-network doctor and in-network hospital and the most you have to pay is the $2500, minus the 142.15 you've already met. Your doctor and the hospital can charge you above and beyond what your insurance "allows" if they are not on your insurance plan network. Out of network you will pay 40% plus the difference between what the hospital/doc charges and the amount your insurance allows. In-network you will pay only 20% of what the insurance allows. No more. So if you go to an out-of-net doc/hospital, they might charge $30,000 to your insurance, but your insurance might say only $5000 is allowed. So the rest will be billed to you. Not a very good route to go since you have a PPO. Make use of your insurance and use your PPO benefits. You pay to have that benefit so you aren't charged an arm and a leg. that's how you keep your cost down. If you do choose an out-of-net doc/hospital, then make them cut you a deal. They can do that since they aren't contracted with your insurance. They don't have to collect your deductible, etc. The hospital i work for, honors patient's in-network benefits if we are not on their ppo plan. That means, we only charge them the co-insurance (20%) and do not collect their deductibles. We write them off completely. There are a lot of hospitals out there doing that and the doc should do it, too. Let me know how it goes. Also, for your out-of-pocket max, you can apply for Care Credit. It is a health expense credit card. If you pay it off in a year, there is no interest. You can apply at www.carecredit.com ... Just make sure the facility accepts it. Most of them do. Or you can go through capital one.. they finance a lot of healthcare for very low interest rates. If you want more info, let me know.
