Hi, dontlookback, and welcome to the forum. Unfortunately, I don't know whether Healthnet would cover your procedure or not. You may want to ask your cardio's office staff, they would probably know if they think your insurance co. would cover the procedure or not. The closure procedure has not been FDA approved for PFO closure, but it has been approved for ASD closure (another type of hole in the heart). This is why there are so many clinical trials going on for PFO closure, so hopefully soon it will be FDA approved. You may also want to ask the cardio staff if the doctor is participating in a clinical trial.
