Shoulder grooving as condition for breast reduction surgery under Cigna? Any way around that? What if you're young?

Hi, I'm wondering if anyone has dealt with Cigna recently regarding breast reduction surgery. They have a condition for approval that "shoulder grooving" be present. What does that entail? How deep does the groove have to be? I'm only 33, but am 32e, I feel like this shoulder grooving condition rules me out since I don't where thin strapped bras and am pretty young to have had such structural changes develop.
