I have an HRA and was offered either the HRA or HSA plan through my employer. they are similar plans but have different deductables and such. basically, you are self insuring (with or without money added by your employer) then once you reach your deductable, co-insurance takes over and pays 80 or 90 percent, depending on the plan. On my HRA, my primary care visits are only $25, but any tests they order I pay for up to my deductable which happens to be $4,000 individual or $8,000 max which them the coinsurancce picks up 100%. depending on your plan you can put money into the HRA to use to pay the deductable. or you can use a flex spending account. These are based on in network.
The idea with these plans is you are paying for some of the costs, so you should want to be a consumer and ask questions about the reason for a test and its costs. However the downfall is when you go into the hospital. I did for pneumonia and was there for 4 days....not much questioning of why when your doctor sends you to hospital in a ambulance from her office!!! Oh well, I will max out my deductable just from this visit so I will be at the 80% pay.
I hope this helps. I am a little scared becasue these plans are more geared for healthy people, not for people with cronic issues that they cannot change or prevent!!!
