Runner,
I had 2 surgeries prior to my ADR and was told scar tissue makes surgery more diffiuclt too. However, in all the posts I've read over the past 4+ years, no one was ever denied and ADR because of scar tissue and I don't recall any post op difficulties blamed on scar tissue.
I have heard of ins. claiming no coverage for complications down the road but again, I can't remember this being an issue, though my memory is not all that reliable anymore.
Sounds like just another denial excuse. So what comes next for you?
