Interesting dilemma. You go to the doctor due to a "bends" issue, diagnosis, PFO, but they wont fix it, just dont dive. On the other hand, you go to the doctor for a "check up" and they find you have a PFO which puts you at a higher risk of stroke.....but they wont fix that either even if it reduces you risk of stroke.
My point is, maybe you're asking the wrong question. Suppose you went to the doctor and said you had suffered a strange issue the other day when you woke up, slurred speech and your right side of your body felt "numb", but it cleared quickly..............TIA's are hard to diagnose and often dont show up. I'm no doctor and would never suggest insurance fraud to reduce your risk of stroke.......................
